Palantir Plummets 2.78% Amid Insider Sales and Short-Seller Pressure: Is the AI Giant Losing Momentum?

Summary
• Palantir (PLTR) trades at $154.33, down 2.78% intraday after opening at $156.22
• Insider selling by CEO Alex Karp and short-seller profits of $1.6B fuel bearish sentiment
• 52-week high of $190 now 20% above current price, raising valuation concerns

Palantir’s sharp intraday decline has ignited a firestorm of speculation, with the stock trading near its 2025 low of $29.31. The move follows a confluence of factors: insider selling, short-seller attacks, and a broader market rotation away from high-growth tech. With $30.9M in turnover and a 1.43% turnover rate, the stock’s volatility underscores the tug-of-war between bulls betting on AI-driven growth and bears questioning its $154B valuation.

Insider Sales and Short-Seller Firepower Trigger Selloff
The selloff stems from a perfect storm of insider selling and short-seller activity. CEO Alex Karp’s recent share sales, coupled with Citron Research’s bearish critique, have amplified skepticism about Palantir’s $338.9 P/E ratio. Compounding this, the Federal Reserve’s dovish comments—while supportive of tech—have failed to offset immediate concerns. Simply Wall St’s analysis highlights a $50–$440 fair value range from 148 investors, reflecting deep uncertainty. Meanwhile, TipRanks’ ‘Hold’ consensus and $156.78 price target suggest the market is pricing in a potential rebound but remains cautious.

Software Sector Mixed as Microsoft Gains, Palantir Struggles
While Palantir falters, Microsoft (MSFT)—the software sector’s leader—trades up 0.03% intraday, highlighting divergent momentum. Microsoft’s stable earnings and cloud dominance contrast with Palantir’s speculative AI narrative. The sector’s broader weakness, however, is evident in mixed sentiment: RTX’s $50B Patriot missile contract win underscores defense-tech resilience, but high-growth software stocks like PLTR face valuation headwinds. This divergence signals a market prioritizing cash flow over speculative AI bets.

Options Playbook: Hedging the Volatility with PLTR20250829P148 and PLTR20250829C160
• RSI: 48.6 (neutral) • MACD: 2.73 (bearish histogram) • Bollinger Bands: Lower band at $144.15 (key support) • 30D MA: $163.61 (above current price) • Leveraged ETF: Direxion Daily PLTR Bull 2X Shares (PLTU) at -5.02%

Palantir’s technicals suggest a short-term bearish trend with a potential bounce near $144.15 (lower Bollinger band). The PLTR20250829P148 put option (delta: -0.276, IV: 64.3%, leverage: 75.25%) and PLTR20250829C160 call (delta: 0.319, IV: 60.6%, leverage: 70.76%) offer asymmetric risk/reward. The put’s high leverage and moderate delta position it to capitalize on a 5% downside (projected price: $146.61, put payoff: $1.39/share). The call’s 70.76% leverage amplifies gains if PLTR rebounds above $160. Both contracts benefit from high gamma (0.0288–0.0326) and theta (-0.008–0.791), ensuring sensitivity to price swings and time decay. Aggressive bulls may consider PLTR20250829C160 into a bounce above $160, while bears should monitor the $148 support level.
