Palantir Technologies Inc (NASDAQ:PLTR) stock surged an eye-popping 350% year-to-date.

But just as retail investors celebrate their portfolios swelling, company insiders — including CFO David A. Glazer and CTO Shyam Sankar — are selling millions of dollars worth of shares.

What Happened: In December alone, Glazer sold $23 million worth of shares, while Sankar offloaded a staggering $367.9 million following an exercise of stock options.

Even CEO Alex Karp joined the selling spree last month, cashing in $132.8 million worth of shares. Despite the eye-catching totals, these transactions represent a tiny fraction of their overall holdings.

So, are they losing faith — or just diversifying?

PLTR Stock’s Bullish Trend

From a technical perspective, Palantir’s stock seems unshakable.

It's trading well above its eight-day, 20-day, 50-day and 200-day moving averages, signaling robust bullish momentum. The Moving Average Convergence Divergence (MACD) indicator, at 5.30, screams “bullish.”

Yet, the Relative Strength Index (RSI) is at 66.20, teetering on overbought territory.

What’s Next: The charts suggest the stock has more room to climb. But with the stock price 313% higher than a year ago, some are questioning how much gas is left in the tank.

So, should you ride the wave or cash in like the execs? While Palantir's future may still be dazzling, history shows insider selling is often a cue to exercise caution—or at least re-evaluate your risk appetite.
