In recent days, Palantir's stock has been showing signs of slowing down. After hitting a new all-time high of $190 on Aug. 12, it has proceeded to trade lower. By Monday, the AI stock would close at just over $174 -- down 8% from its recent high.

The stock has climbed 2.5x since early January and now trades at around $185 per share. After such a rapid ascent, should investors holding sizable gains cash out?

The sudden reversal shows how the hottest AI trade and top-performing stock of the year is colliding with a broader market rotation out of big tech.
