Retail Stock Investors Can Now Imitate the Pros With AI Trading Tools

Artificial intelligence trading tools that analyze reams of data and build portfolios are already shaking up Wall Street. But as they increasingly become available to retail investors, the entire stock market is in for a seismic transformation.

The retail crowd owns roughly 25% of the US stock market directly and over 60% indirectly through individual retirement accounts, 401(K)s and the like, according to calculations by Barclays Plc. They’re known for loyalty to a handful of high-flyers, like technology giants Tesla Inc. and Nvidia Corp., and a fascination with highly volatile so-called meme stocks like GameStop Corp. In many cases, their trading is disconnected from the underlying fundamentals of the shares they’re buying.
