The latest literature reveals the homogenization risk of Wall Street in the AI era. The proliferation of similar models is accelerating the decay of alpha.

From hedge funds to wealth management firms, Wall Street is embracing artificial intelligence in hopes of gaining an investment edge. Now, researchers are beginning to ask what will happen when more and more investors turn to similar AI models to seek this advantage: will they buy the same stocks, react to the same headlines, and sometimes make the same mistakes? Recent studies suggest that this situation could have implications for the entire market. While AI may enable investors to act faster and access more information, it could also lead to more crowded trades, easier manipulation of the system, and difficulties in controlling risk. Multiple recent studies indicate that as investors converge on the same opportunities, the widespread use of artificial intelligence may shorten the lifespan of profitable trading signals. Additionally, research has found that AI models systematically take on unexpected risks, or may be manipulated by the information they ingest.
