Alpha Decay: Why Speed Matters

When a major hedge fund files a 13F revealing a massive new position, that information is pure Alpha. The moment the market processes this information, the price adjusts, and the Alpha decays.

For the active trader, the objective is clear: capture the signal before the decay. The challenge is technical.
