These stocks are trading at attractive valuations relative to their history, especially in light of their opportunities in the artificial intelligence space.

As of the end of the second quarter, Meta had nearly 3.3 billion daily active users (DAUs). That's a huge advantage for the company in many ways, but consider this: Meta is in a position to introduce its AI-powered features to roughly 40% of the world's population.

Chipsets known as graphics processing units (GPUs) are an integral component in the development of artificial intelligence (AI) applications. At the moment, Nvidia (NASDAQ: NVDA) holds an estimated 88% of the AI GPU market thanks to its industry-leading A100 and H100 GPUs.

Apple and Nvidia have both announced major share buyback programs, but I see one of these artificial intelligence (AI) players as the obvious winner in the long term.

Using Wall Street analysts' price targets to determine whether a stock is a buy or a sell isn't the best strategy. While it should help inform investors of how others think of the stock, it shouldn't be the be-all and end-all. One popular artificial intelligence (AI) stock that these analysts (on average) say to sell now is Palantir (NYSE: PLTR).
