Alpha Erosion

Alpha erosion refers to the decline in the excess returns of a trading strategy as its unique edge is identified and exploited by other market participants. This is a natural consequence of efficient markets, where profitable opportunities are quickly competed away.

Alpha erosion can be caused by increased capital flowing into a strategy, improvements in technology by competitors, or changes in the underlying market structure. To combat this, traders must constantly innovate and seek new sources of alpha.

Monitoring alpha decay is a critical part of the strategy lifecycle, allowing traders to know when a strategy has reached its limit and needs to be retired or overhauled. It is the fundamental challenge of maintaining a profitable trading business.
