Recent periods of elevated volatility, rapid shifts in liquidity, and changing correlation structures have highlighted how quickly market conditions can evolve. In this environment, many alpha signals are decaying faster than in prior cycles as market structure, automation, and competitive dynamics continue to compress effective strategy lifespans.

Shorter regime stability and increased sensitivity to timing and execution mean that signal degradation is often detected late—frequently after capital has been deployed and opportunity cost has already accrued.

This session examines how hedge funds are responding to that environment, and why the ability to understand change quickly has become a decisive factor in maintaining alpha.

In this webinar, we explore:

  • How signal behavior evolves under live market conditions
  • Why detection lag now carries direct P&L and capital allocation impact
  • Where value is lost quietly through delayed activation or late retirement of strategies
  • How portfolio interaction amplifies small signal-level changes
  • Which analytical capabilities shorten the time from exposure to understanding

The focus is on navigating signal decay with greater clarity and control as markets continue to evolve.
