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.

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.
