Palantir's Momentum Is Undeniable, But Is the Stock a Buy at These Levels?

Palantir Technologies (PLTR 1.50%) has been on fire over the past few years, driven higher by the accelerating adoption of artificial intelligence (AI) and its legacy government contracts business. Shares of the data mining and AI specialist recently hit a new all-time high and are up 475% over the past year, more than 28 times the 17% gains of the S&P 500.
