Having said that, if I were to choose just one stock to invest in AI, it would have to be Amazon ( AMZN -0.32%). It offers an excellent combination of growth potential and safety, and there's a solid case to be made that it is the most attractively valued of the megacap tech stocks right now.

Two hot stocks in this sector are Palantir Technologies (NASDAQ: PLTR) and SoundHound AI (NASDAQ: SOUN). Palantir's shares had surged by more than 300% over the prior 12 months, while SoundHound had skyrocketed by 600%.

That sets the table for continued growth over the coming years. Analysts estimate that Nvidia will grow earnings by an average of 38% annually for the next three to five years. Today, Nvidia trades at a forward P/E ratio of 51, a rock-solid value for its anticipated growth.

This top-performing ETF's largest three stock holdings are Nvidia, Taiwan Semiconductor Manufacturing, and Broadcom.

But it's off to a very rocky start in 2025 -- last week (ended Friday, Jan. 10), its price plunged by 32% as investors trimmed their bets on stocks with elevated valuations.
