Palantir Technologies (NASDAQ: PLTR) was the standout and number one performer in the S&P 500 in 2024, with its stock skyrocketing 340% in 2024 and elevating its market capitalization to an impressive $163 as of the January 17 close.

Palantir's share price has outpaced the company's growth, pushing its price-to-earnings ratio to nearly 360. That's among the highest valuations on the market for any company. While analysts expect strong long-term earnings growth (27% annualized), it's nowhere near enough to justify such a high price.
