Back in the dot-com boom era, stock splits became commonplace in response to soaring share prices. Amid the current artificial intelligence (AI) boom, a similar pattern could be developing. Already, several AI companies have split their shares, and more splits could be on the way among the others that are trading at lofty prices.

Plenty of AI stocks trade down from their recent peaks, and the Nasdaq Composite, the tech-heavy index, hit an intraday peak on July 11. The index is down 5.5% from that peak after a recent recovery. Similarly, the VanEck Semiconductor ETF, which is led by the chip stocks that are key in the AI rally, is down 18% from its peak on the same day.

The expectations for many artificial intelligence (AI) stocks are extremely high. If an earnings report isn't absolutely perfect, maybe even better than perfect, investors could sell off shares, sending the stock price down.

These companies are getting a nice boost thanks to AI, a trend that's likely to continue thanks to their huge addressable markets.
