Climbing the crowded mountain: Generating alpha with high-performance analytics 

Capital markets are more competitive than ever, with quantitative researchers and analysts from leading firms all climbing the same mountain to find innovative ways of generating alpha. This blog explores the role that high-performance data analytics plays in helping these climbers reach the summit faster than their competitors. 

When Sir Edmund Hillary attained the summit of Everest in 1953, he became the first person to reach the highest point on Earth, succeeding where almost a dozen well-funded expeditions had failed. Yet, seven decades later, hundreds of tourists make the same ascent each year—thanks to a potent combination of better knowledge and technology. 

Himalayan mountains and valleys may differ significantly from the peaks and troughs of financial markets, but your trading desks face a similar problem in today’s search for profit, or ‘alpha’. Like the summit of Everest, markets are more crowded than ever—and traditional capabilities no longer leave you far above the competition. 

Not only have today’s market participants learned from the hard-won strategies of others, but advancing technology also means it’s easier for them to deploy sophisticated models, algorithms, and other capabilities that only the most prominent firms possessed just a decade or two ago. 

While finding a competitive edge is more complicated than ever, capital markets are also much more complex today. It’s not just the worldwide scope, multiplying financial instruments, or growing regulation; constant connectivity and business digitization mean the sheer variety, volume, and velocity of relevant data can be overwhelming. 

But it can also be a source of advantage. 

Read on as we explore how high-performance data analytics can optimize the ideation and execution of trading strategies, accelerate alpha generation, and sharpen your competitive edge. 

In this hyper-competitive environment, innovation is vital to consistent alpha generation—and the ability to drink from today’s firehose of data holds the key. 

Drinking from the firehose 

Information now flows at the speed of thought around the world, making modern capital markets much more efficient. 

With ubiquitous automation and high-frequency trading, markets react faster than ever, reducing the window for adjustments. Market participants can also identify inefficiencies more swiftly, making it increasingly challenging to uncover untapped opportunities for exploitation. 

In this hyper-competitive environment, innovation is vital to consistent alpha generation—and the ability to drink from today’s firehose of data holds the key. 

When your teams can harness high-performance analytics to process, integrate, and evaluate a staggering array of data in real time, they can access vital insights and make the best possible choices when seeking alpha. Beyond enabling more effective execution, highly performant analytics also slashes the time it takes to develop new and improved trading strategies—allowing you to iterate models and deploy ideas faster than competitors. 

But it’s no easy task. Extracting meaningful insights from petabyte-scale data fast enough to drive moment-to-moment trading decisions is a big challenge. 

Leveraging high-performance data analytics 

Effective data analytics comes down to scale, speed, and depth of insight. Here are some must-have considerations for any advanced analytics platform. 

Real-time processing… 

Your quants and traders need access to high-quality real-time data for the most accurate and up-to-date view of market conditions. 

By ingesting large volumes of streaming data from diverse inputs and processing it in milliseconds, high-performance analytics makes it quicker and easier to identify patterns or anomalies and make fast, informed decisions based on market signals. But that alone isn’t enough. 

…enriched with historical data 

To drive critical, in-the-moment decisions, a top-performing analytics stack also needs to fuse streaming market data with historical information at speed and scale. 

Historical information is vital to contextualize financial data—giving traders better visibility into market risks or opportunities and empowering them to backtest strategies robustly. 

Time-series support 

Time-series databases are designed to handle high-frequency, high-volume information streams, capturing the chronological flow and interdependent nature of market events. 

By ensuring your analytics stack supports time-series data capture and low-latency processing, your quants can harness granular insights into market behavior and trends over time—detecting anomalies, finding patterns, and enabling predictive modeling by comparing similar situations from the past. 

Comprehensive data integration 

Beyond processing real-time, historical, and time-series data, high-performance analytics must also handle varied data sources and make it easy to load, transform, query, or visualize massive datasets. 

To create a holistic view of the market, you need access to structured information, like price and volume feeds, and unstructured data, like documents, images, or videos. 

While structured data has long been the backbone of algorithmic trading, finding connections with unstructured data can yield deeper insights and new opportunities for alpha generation. Read Mark Palmer’s blog, “The New Dynamic Data Duo”, to learn more. 

Data cleansing 

Whatever markets you’re trading, don’t forget the importance of high-quality data. Early validation is critical, ensuring that inaccurate or duplicate data is identified as soon as it enters the system. This prevents flawed data from affecting downstream analytics. 

Normalization plays an equally important role, as data from multiple sources—market feeds, platforms, and internal systems—often comes in various formats. Consistent data structures allow for seamless integration and more reliable insights. 

Real-time data integrity checks ensure that only accurate, complete, and reliable data informs trading models. For firms handling large volumes of data, ensure you invest in an analytics solution offering high-speed validation, normalization, and integrity checks built for the scale and complexity of capital markets. 

AI and machine learning 

Markets don’t wait, so crunching petabyte-scale data for actionable insights must happen quickly. As such, high-performance data analytics platforms increasingly leverage complex algorithms and AI and machine learning to help traders detect hard-to-see patterns, automatically refine strategies, or drive ideation. 

In a recent survey by Mercer, around 91% of investment managers said they are using or plan to use AI in their investment processes. 

Scalability 

Finally, don’t forget the importance of scalability and flexibility. Any analytics solution should be able to grow with your needs as trading operations and data volumes rise, scaling up both compute and storage as required to prevent performance degradation. 

Whatever markets you’re trading, don’t forget the importance of high-quality data. Early validation is critical, ensuring that inaccurate or duplicate data is identified as soon as it enters the system. This prevents flawed data from affecting downstream analytics. 

The future of alpha 

Techniques for generating alpha have come a long way, but innovation in capital markets is only accelerating. 

Emerging technologies are transforming what data analytics can do, letting traders harness more information than ever, create unimaginable insight, and make hyper-accurate market forecasts. 

Here are three areas to consider as you plan for the future. 

Generative AI (GenAI) 

Progress in GenAI enables ever-faster analytics and the ability to ingest and process more extensive and varied datasets for richer insights. 

Many capital market firms are already becoming ‘AI-first’ enterprises, making AI a core component of their culture, infrastructure, and decision-making to drive innovation and competitive advantage. Almost two-thirds of organizations surveyed by Bain & Company in 2024 cite GenAI as a top three priority over the next two years. The McKinsey Global Institute also estimates that GenAI can offer $200-340 billion in annual value for the banking sector. 

While real-time data and time-series analysis remain critical for responsive decision-making, the integration of GenAI will supercharge the performance of models and analytics, while reducing complexity and cost. 

However, the most significant value will be leveraging the full spectrum of traditional and emerging AI capabilities to create new connections and generate fresh ideas.  

Unlocking the value of alternative data 

The more data you have, the more it compounds in value. Actionable insights come from finding links, correlations, and patterns. 

We’ve already covered the benefits of adding unstructured datasets like call transcripts or analyst reports—but they are challenging to ingest, process, and interrogate for helpful information. However, that’s changing. 

Gaining insights from an even wider range of alternative data sources is becoming faster, cheaper, and easier thanks to advances in large language models (LLMs) and vector databases. While LLMs provide the ability to analyze and understand a considerable volume of unstructured data, for instance through intelligent document processing, vector databases also enable real-time querying and retrieval

The ability to tap into much more varied forms of unstructured data will fuel an analytics revolution, enhancing your ability to find unique and unexpected insights that were previously invisible. 

Data inputs spanning everything from social media sentiment, web traffic, and geolocation data to weather patterns and satellite images will soon be a mainstay of competitive advantage. 

According to a report from the Alternative Investment Management Association, nearly 70% of leading hedge funds are already using alternative data in their quest for alpha.  Meanwhile, Deloitte forecasts that the market for alternative data will be larger than that for traditional financial information by 2029. 

Advanced predictive analytics 

AI-powered predictive analytics using vast real-time, time-series, and historical datasets will strengthen the ability of trading desks to foresee market movements or broader trends. This will enable more informed, proactive decisions—capitalizing on emerging opportunities and significantly reducing the risk from unexpected events. 

But remember, feeding AI the wrong data will give you incorrect predictions. You need clean, trustworthy data–in vector form–to train accurate and efficient AI models. 

In this webinar, we explored Wall Street’s leading-edge applications of high-frequency data in quantitative trading.

Staying ahead of the curve 

As innovation accelerates, it’s crucial to prepare for tomorrow’s capabilities today. If you don’t have a technology stack that’s optimized for high-performance analytics, now’s the time to focus on this vital element in your quest for alpha. 

You don’t invest in technology for technology’s sake—so aligning strategies for data analytics with key business goals and specific pain points is crucial. It all comes down to six letters: TCO and ROI. 

If you’re currently depending on a patchwork of legacy systems, don’t accept the combination of higher infrastructure costs and slower analytics that causes you to miss out on alpha-generating opportunities. 

To support ongoing innovation, look for analytics platforms that are easy to deploy and can flexibly integrate with new technologies as they appear. It’s vital to stay current on emerging trends and continuously refine your approach to keep pace with what’s possible. 

You may not be scaling Everest, but make no mistake, the race to the top has started. Data is exploding in complexity and volume, system capabilities are increasing, and your competitors are already exploring new capabilities.

    The ultimate guide to choosing embedding models for AI applications

    Backtesting at scale with highly performant data analytics

    Speed and accuracy are crucial when backtesting trading strategies.

    To gain the edge over your competitors, your data analytics systems must ingest huge volumes of data, with minimal latency, and seamlessly integrate with alternative data sources.

    This blog identifies the essential components you should consider to optimize your analytics tech stack and incorporate emerging technologies (like GenAI) to enhance backtesting at scale.

    Key considerations for effective backtesting data analytics

    When you backtest, you’re using your data analytics stack to create a digital twin of the markets within a ‘sandbox’.

    By applying a set of rules to real-world, historical market data, you can evaluate how a trading strategy would have performed within a risk-free testing ground. The more performant this testing ground is, the less time it takes to develop new and improved trading strategies, allowing you to iterate and deploy your ideas faster than your competitors.

    But how do you ensure your backtesting tech stack can operate at the speed and scale you need to be successful? Here, we’ll dig a little deeper into these essential components of effective backtesting.

    The key considerations are:

    Data quality and management: Access to high quality historical data from a reputable source is essential for backtesting at scale. Focus on data aggregation, quality controls, and structured data to improve the speed and ease of retrieving data. 

    Speed and efficiency: Speed and efficiency of your data analytics stack is crucial. Speed-to-insight is everything and any down time or latency can lead to missed opportunities and increased exposure to risk.

    User expertise:The effectiveness of your data analytics stack is also dependent on the expertise of the users and their understanding of the programming language on which your solution runs.

    Most importantly…

    Scalability and flexibility: Determining the viability of a trading strategy requires the ability to process petabyte-scale volumes of high-frequency data – sometimes handling billions of events per day. You then need to be able to run concurrent queries to continually fine tune parameters and run quicker simulations. Your chosen database and analytics tools should be scalable to handle all of this without sacrificing performance.

    By working with a platform that incorporates these essential features, you can run more informed simulations, more often. This shortens your time-to insight and enhances the level of confidence in your approach, obtaining accurate, empirical evidence that supports or opposes your strategies.

    Having highly performant data analytics technology is crucial, but success doesn’t stop there. To gain the insights you need to optimize trade execution and generate Alpha, you need a granular view, informed by both historical and real-time data.

    Fuse high-quality historical time series data with real-time data

    The biggest questions you face while backtesting require context, which is why high-quality historical data, from a reputable source, is vital. However, for a backtest to be valuable, it must also be timely and accurate. The accuracy is impacted by the realism of the backtest, which means the simulation must reflect real-world conditions.

    Processing high-frequency market data for low-latency decision making requires the fusion of a real-time view of the market with the ability to put conditions into historical context quickly.
    Processing high-frequency market data for low-latency decision making requires the fusion of a real-time view of the market with the ability to put conditions into historical context quickly.

    You need massive amounts of historical data applied to real-time streaming data to accomplish this. Think of it like the human body’s nervous system. Real-time streaming data provides the sensory input. However, we require the accumulated history of whether that input means danger or opportunity to put the situation in perspective and make effective judgements.

    Compare today’s market conditions to the last similar situation to fine-tune predictive model​
    A time series database is like a video replay for market data that quants can use to analyze markets (e.g.,AS-IF)

    The key is a high-performance system that allow you to test more quickly and accurately than your competition. By combining real-time streaming data with a time-series view of historical data, you can backtest your strategies against past market conditions, assessing their viability against previous trends and behaviours.

    Find this balance when you backtest by leveraging a database that makes it easy to combine high-frequency, real-time data and temporal, historical data in one place. This allows applications to perform tick-level “as-if” analysis to compare current conditions to the past and make smarter intraday backtesting decisions.

    Real-time and historical time series aren’t the only two data types you can fuse together to enhance your analytics…

    Backtesting with GenAI: Combining structured and unstructured data

    Structured data has long been utilized in algorithmic trading to predict market movements. However, advancements in GenAI are making it easier and more cost effective to process unstructured data (PDF documents, web pages, image/video/audio files, etc.) for vector-based analysis.

    Combining these types of data in the backtesting process is providing new opportunities to gain an analytics edge (Read “The new dynamic data duo” from Mark Palmer for a more detailed explanation).

    These types of applications require data management systems to connect and combine unstructured with structured data via vector embeddings, synthetic data sources, and data warehouses to help prepare data for analysis. For example, new KX capabilities enable the generation of vector embeddings on unstructured documents, making them available for real-time queries.  

    Using LLMs to merge structured market data with unstructured sources such as SEC filings and social media sentiment means you can generate queries that not only assess how your portfolio has performed, but why it performed that way.

    Combining structured and unstructured data marries accuracy with serendipitous discovery. It provides more expansive and specific insights.

    For example, let’s assume a series of trades haven’t performed as well as expected. Your system can use its access to news outlets, social media sentiment, and other unstructured sources to attribute the downturn to broad factors such as market instability, specific corporate developments, and currency shifts, offering a more detailed perspective on potential causes for the underperformance.

    The combination of structured and unstructured data represents a revolutionary step in data analytics, enhancing your ability to backtest with unique insights that were previously hidden.

    Backtesting at scale: wrapped up

    If you want to assess the viability and effectiveness of your trading hypotheses and get watertight strategies to market faster than competitors, then you need a highly performant analytics platform.

    To backtest at scale, your analytics platform should offer speed, scalability, and efficient data management. It must also support multiple data sources and enable the comprehensive testing of complex trading strategies.

    One such platform is kdb Insights Enterprise, a cloud-native, high-performance, and scalable analytics solution for real-time analysis of streaming and historical data. Ideal for quants and data scientists, Insights Enterprise delivers fast time-to-value, works straight out of the box, and will grow with your needs.

      The misunderstood importance of high-fidelity data

      Why does the gentle crackle of a vinyl record hold such a special place in our hearts? Analog experiences remain highly valued for their quality and tangible feel. The vinyl record renaissance exemplifies this – in the age of music streaming, many still appreciate vinyl’s richer, more immersive experience. Sometimes, a slower, higher-fidelity analog format offers an essential counterpoint to our instant-everything culture. It connects us to a level of quality and experience that digital struggles to replicate. 

      High data fidelity is crucial in data analytics too – especially for applications that deal with high-frequency time series data streams. Yet technologists often dismiss tuning into streaming data because they “don’t need to make real-time automated decisions.”

      But they’re mistaken: rich, immersive, high-fidelity streaming data is for everyone. 

      Let’s explore the misunderstood importance in more detail, particularly in the context of market data and quantitative trading. 

      Understanding data fidelity 

      Data fidelity refers to the accuracy and completeness of data as it is captured and stored. Most companies “over-digest” data through down-sampling, complex transformations during ETL, summarization and aggregation, or statistical techniques. While these methods are sufficient to get a bird’s-eye view of activity—such as obtaining the close-of-day stock price—they fall short when rich, high-fidelity insight is required. 

      High-fidelity data management stores are in time-series order – meaning they are chronologically arranged within a sequence over time. This helps answer some of our most important questions about space, time, and order, and complements traditional, transactional data.

      High-fidelity data by example in quantitative trading 

      Consider the world of financial market data and quantitative trading. Stock prices fluctuate hundreds of thousands, or even millions, of times a day. For many applications, a summarized version of this data is adequate — the price at each minute, hour, or end of the day.  

      However, high-fidelity data is indispensable for analysts and algorithmic traders who need to understand micro-movements and develop sophisticated trading strategies. For example, high-fidelity data allows for tick-by-tick analysis, where every price change is recorded and analyzed.  

      This level of detail is crucial for understanding the nuances of stock movements and conducting AS-IF analysis, a term used in time-series data analytics to compare time windows. AS-IF analysis makes it easy to compare today’s market conditions to the last similar situation so that traders can fine-tune today’s predictive model and trading strategies. 

      Compare today’s market conditions to the last similar situation to fine-tune predictive model​

      For example, high-fidelity data is essential to AS-IF comparison for ‘pairs trading’, where the price movements of related stocks are analyzed. Pairs trading capitalizes on the principle that the prices of related stocks tend to move together. However, trading opportunities arise when these stocks deviate from their usual patterns. Identifying these opportunities requires a detailed, tick-by-tick record of stock movements and other market indicators. 

      Comparing different windows in time helps traders anticipate how today’s market conditions might play out and predict the best trading strategies to employ by understanding data movements from previous, similar periods. 

      Applications beyond finance 

      The need for high-fidelity data extends beyond financial markets:

      • For manufacturing applications involving the streaming of IoT (Internet of Things) sensor data, high-fidelity data can be crucial for diagnosing equipment failures. By replaying every sensor data change event, engineers can pinpoint the exact moment and cause of a failure 
      • In e-commerce, high-fidelity data can help understand customer behavior. By analyzing every click a user makes on their journey to checkout, businesses can identify where customers abandon their shopping carts, leading to more effective strategies for reducing cart abandonment rates 
      • In high-precision agricultural applications, drone and satellite imagery stream into the data analytics team. A high-fidelity view of data that overlays weather, soil quality, and irrigation, alongside imagery, can help industrialized agricultural teams analyze actions that optimize cost, safety, and yield.

      In essence, any application with access to time-series streaming data has applications that benefit from a high-fidelity way of looking at their data.  

      The business advantage of high-fidelity data 

      Most companies struggle to store and analyze high-fidelity data due to the limitations of traditional relational and NoSQL databases, which are not optimized for time series data. This is where time series databases excel. They’re designed to handle high-frequency, high-volume data streams, making them ideal for storing and analyzing high-fidelity tick data. 

      The applications of high-fidelity data are numerous and varied, spanning industries from finance to manufacturing to e-commerce. Specialized time series databases handle and analyze this type of data, which sets it apart from other database management platforms.  

      As part of your innovation portfolio, exploring the possibilities of storing and analyzing high-fidelity tick or time series data can yield game-changing insight.  

      In summary, high-fidelity data is a technical requirement and a strategic asset that can drive significant business value.

        Structure, meet serendipity: Integrating structured and unstructured data for left- and right-brain decisions

        Most technologists view using unstructured data (conversations, text, images, video) and LLMs as a surging wave of technology capabilities. But the truth is, it’s more than that: unstructured data adds an element of surprise and serendipity to using data. It decouples left—and right-brain thinking to improve insight generation and decision-making. 

        A recent MIT study points to the possibility of elevating analytics in this way. It observed 444 participants performing complex tasks associated with communicating key decisions like an analysis plan by a data scientist about how they plan to explore a dataset.  The study found that using GenAI increased speed by 44% and improved quality by 20%. The study shows that analysts, data scientists, and decision-makers of all kinds can use unstructured data and GenAI to elevate decision-making when they use unstructured and structured data. 

        This form of data-fueled decision-making combines the unstructured data required to power right-brain, creative, intuitive, big-picture thinking—with structured data for left-brain analytical, logical, and fact-based insight to inform balanced decision-making. 

        Here’s how it works. 

        Diagram comparing Structured Data to Left-Brain thinking and Unstructured Data to Right Brain thinking

        Unstructured data: A creative, intuitive, big-picture data copilot 

        Unstructured data powers creative, intuitive, big-picture thinking. Documents and videos are used to tell stories on a stream of consciousness. In contrast to structured data, it’s designed to unfold ideas in a serendipitous flow – a journey from point A to point B, with arcs, turns, and shifts in context. 

        Navigating unstructured data is similarly serendipitous. It matches how the brain processes fuzzy logic, relationships among ideas, and pattern-matching. The rise of LLMs and generative AI is largely because prompt-based exploration matches how our brains think about the world – you ask questions via prompts, and neural networks predict what might resolve your quandary.  Like your brain, neural networks help analyze the big picture, generate new ideas, and connect previously unconnected concepts. 

        This creative, right-brain computing style is modeled after how our brains work. Warren Mcculloch and Walter Pitts published the seminal paper in 1943 that theorized how computers might mimic our creative brains in A Logical Calculus of the Ideas Immanent in Nervous Activity. In it, they described computing that casts a “net” around data that forms a pattern and sparks creative insight in the human brain. They wrote: 

        “…Neural events and their relations can be treated using propositional logic. It is found that the behavior of every net can be described in these terms, with the addition of more complicated logical means for nets containing circles, and that for any logical expression satisfying certain conditions, one can find a net behaving in the fashion it describes.” 

        Eighty years later, neural networks are the foundation of generative AI and machine learning. They create “nets” around data, similar to how humans pose questions. Like the neural pathways in our brain, GenAI uses unstructured data to match patterns.  

        So, unstructured data provides a new frontier of data exploration, one that complements the creative “nets” that our brains cast naturally over data. But, alone, unstructured data is fuel for our creativity, and it, too, can benefit from some right-brain capabilities. From a data point of view, the right brain is informed by structured data.  

        Structured data: An analytical, logical, fact-based copilot 

        Structured data is digested, curated, and correct. The single source of the truth. Structured data is our human attempt to place the world in order and forms the foundation of analytical, logical, fact-based decision-making. 

        Above all, it must be high-fidelity, clean, secure, and aligned carefully to corporate data structures. Born from the desire to track revenue, costs, and assets, structured data exists to provide an accurate view of physical objects (products, buildings, geography), transactions (purchases, customer interactions, conversations), and companies (employees, reporting hierarchy, distribution networks) and concepts (codes, regulations, and processes). For analytics, structured data is truth serum.  

        But digested data loses its original fidelity, structure, and serendipity. Yes, structured data shows us that we sold 1,000 units of Widget X last week, but it can’t tell us why customers made those purchasing decisions. It’s not intended to speculate or predict what might happen next. Interpretation is entirely left to the human operator.  

        By combining access to unstructured and structured data in one place, we gain a new way to combine both the left and right sides brain as we explore data. 

        This demo explains how our vector database, KDB.AI, works with structured and unstructured data to find similar data across time and meaning, and extend the knowledge of Large Language Models.

        Where unstructured exploration meets structured certainty, by example 

        Combining structured and unstructured data marries accuracy with serendipitous discovery for daily judgments. For example, every investor wants to understand why they made or lost money. Generative AI can help answer that data in a generic way (below, left). When we ask unstructured data why our portfolio declined in value, AI uses unstructured data to provide a remarkably good human-based response: general market volatility, company-specific news, and currency fluctuations provide an expansive view of what might have made your portfolio decline in value.  

        But the problem with unstructured-data-only answers is that they’re generic. Trained on a massive corpus of public data, they supply the most least-common-denominator, generic answers. What we really want to know is why our portfolio declined in value, not an expansive exploration of all the options. 

        Fusing unstructured data from GenAI with structured data about our portfolios provides the ultimate answer.  GenAI, with prompt engineering, interjects the specifics of how your portfolio performed, why your performance varied, and how your choice compared to its comparable index.  

        The combination of expansive and specific insight is shown in the right column, below: 

        Bringing left-and-right brain thinking together in one technology backplane is a new, ideal analytical computing model. Creative, yet logical, questions can be asked and answered. 

        But all of this is harder than it may sound for five reasons. 

        How to build a bridge between unstructured and structured data 

        Unstructured and structured data live on different technology islands: unstructured data on Document Island and structured data on Table Island. Until now, different algorithms, databases, and programming interfaces have been used to process each. Hybrid search builds a bridge between Document and Table Island to make left-and-right brain queries possible. 

        Hybrid search requires five technical elements: 

        1. Hybrid data indexing  
        1. Hybrid query processing 
        1. High-frequency streaming data 
        1. Hybrid time series organization 
        1. Vector embedding-free storage optimization 

        In our next post, we’ll explore these elements and how they build a bridge between creative and logical data-driven insights. Together, they form a new way of constructing an enterprise data backplane with an AI Factory approach to combine both data types in one hybrid context.  

        The business possibilities of combining left-and-right brain analytics are as fundamental as the shift in how decision-making works in the context of AI. So, introduce new thinking methods based on new hybrid data technology capabilities for elevated data exploration and decision-making.

        The Montauk Diaries – Two Stars Collide

        by Steve Wilcockson

         

        Two Stars Collide: Thursday at KX CON [23]

         

        My favorite line that drew audible gasps at the opening day at the packed KX CON [23]

        “I don’t work in q, but beautiful beautiful Python” said Erin Stanton of Virtu Financial simply and eloquently. As the q devotees in the audience chuckled, she qualified her statement further “I’m a data scientist. I love Python.”

        The q devotees had their moments later however when Pierre Kovalev of the KX Core Team Developer didn’t show Powerpoint, but 14 rounds of q, interactively swapping characters in his code on the fly to demonstrate key language concepts. The audience lapped up the q show, it was brilliant.

        Before I return to how Python and kdb/q stars collide, I’ll note the many announcements during the day, which are covered elsewhere and to which I may return in a later blog. They include:

        Also, Kevin Webster of Columbia University and Imperial College highlighted the critical role of kdb in price impact work. He referenced many of my favorite price impact academics, many hailing from the great Capital Fund Management (CFM).

        Yet the compelling theme throughout Thursday at KX CON [23] was the remarkable blend of the dedicated, hyper-efficient kdb/q and data science creativity offered up by Python.

        Erin’s Story

        For me, Erin Stanton’s story was absolutely compelling. Her team at broker Virtu Financial had converted a few years back what seemed to be largely static, formulaic SQL applications into meaningful research applications. The new generation of apps was built with Python, kdb behind the scenes serving up clean, consistent data efficiently and quickly.

        “For me as a data scientist, a Python app was like Xmas morning. But the secret sauce was kdb underneath. I want clean data for my Python, and I did not have that problem any more. One example, I had a SQL report that took 8 hours. It takes 5 minutes in Python and kdb.”

        The Virtu story shows Python/kdb interoperability. Python allows them to express analytics, most notably machine learning models (random forests had more mentions in 30 minutes than I’ve heard in a year working at KX, which was an utter delight! I’ve missed them). Her team could apply their models to data sets amounting to 75k orders a day, in one case 6 million orders over a 4 months data period, an unusual time horizon but one which covered differing market volatilities for training and key feature extraction. They could specify different, shorter time horizons, apply different decision metrics. ”I never have problems pulling the data.” The result: feature engineering for machine learning models that drives better prediction and greater client value. With this, Virtu Financial have been able to “provide machine learning as a service to the buyside… We give them a feature engineering model set relevant to their situation!,” driven by Python, data served up by kdb.

        The Highest Frequency Hedge Fund Story

        I won’t name the second speaker, but let’s just say they’re leaders on the high-tech algorithmic buy-side. They want Python to exhibit q-level performance. That way, their technical teams can use Python-grade utilities that can deliver real-time event processing and a wealth of analytics. For them, 80 to 100 nodes could process a breathtaking trillion+ events per day, serviced by a sizeable set of Python-led computational engines.

        Overcoming the perceived hurdle of expressive yet challenging q at the hedge fund, PyKX bridges Python to the power of kdb/q. Their traders, quant researchers and software engineers could embed kdb+ capabilities to deliver very acceptable performance for the majority of their (interconnected, graph-node implemented) Python-led use cases. With no need for C++ plug-ins, Python controls the program flow. Behind-the-scenes, the process of conversion between NumPy, pandas, arrow and kdb objects is abstracted away.

        This is a really powerful use case from a leader in its field, showing how kdb can be embedded directly into Python applications for real-time, ultra-fast analytics and processing.

        Alex’s Story

        Alex Donohoe of TD Securities took another angle for his exploration of Python & kdb. For one thing, he worked with over-the-counter products (FX and fixed income primarily) which meant “very dirty data compared to equities.” However, the primary impact was to explore how Python and kdb could drive successful collaboration across his teams, from data scientists and engineers to domain experts, sales teams and IT teams.

        Alex’s personal story was fascinating. As a physics graduate, he’d reluctantly picked up kdb in a former life, “can’t I just take this data and stick it somewhere else, e.g., MATLAB?”

        He stuck with kdb.

        “I grew to love it, the cleanliness of the [q] language,” “very elegant for joins” On joining TD, he was forced to go without and worked with Pandas, but he built his ecosystem in such a way that he could integrate with kdb at a later date, which he and his team indeed did. His journey therefore had gone from “not really liking kdb very much at all to really enjoying it, to missing it”, appreciating its ability to handle difficult maths efficiently, for example “you  do need a lot of compute to look at flow toxicity.” He learnt that Python could offer interesting signals out of the box including non high-frequency signals, was great for plumbing, yet kdb remained unsurpassed for its number crunching.

        Having finally introduced kdb to TD, he’s careful to promote it well and wisely. “I want more kdb so I choose to reduce the barriers to entry.” His teams mostly start with Python, but they move into kdb as the problems hit the kdb sweet spot.

        On his kdb and Python journey, he noted some interesting, perhaps surprising, findings. “Python data explorers are not good. I can’t see timestamps. I have to copy & paste to Excel, painfully. Frictions add up quickly.”  He felt “kdb data inspection was much better.” From a Java perspective too, he looks forward to mimicking the developmental capabilities of Java when able to use kdb in VS Code.”

        Overall, he loved that data engineers, quants and electronic traders could leverage Python, but draw on his kdb developers to further support them. Downstream risk, compliance and sales teams could also more easily derive meaningful insights more quickly, particularly important as they became more data aware wanting to serve themselves.

        Thursday at KX CON [23]

        The first day of KX CON [23] was brilliant. a great swathe of great announcements, and superb presentations. For me, the highlight was the different stories of how when Python and kdb stars align, magic happens, while the q devotees saw some brilliant q code.
