Palantir Plummets 3% as Tech Sector Reels: What’s Fueling the Selloff?

Summary
• Palantir (PLTR) trades at $151.39, down 3.04% from its $156.14 previous close
• Intraday range spans $148.04 to $158.96, reflecting sharp volatility
• 52-week high of $190 and dynamic PE ratio of 332.08 highlight valuation concerns

Palantir’s sharp intraday decline has drawn attention as the stock struggles to hold key levels amid broader tech sector turbulence. The selloff coincides with Seagate’s (STX) outperformance in AI-driven storage demand and growing skepticism about PLTR’s stretched valuation. With turnover at 50 million shares and a 2.3% turnover rate, the stock is testing critical support zones as traders reassess its momentum.

Valuation Concerns and Sector Rotation Weigh on PLTR
Palantir’s 3% drop reflects a confluence of factors: a 242x forward P/E ratio, sector rotation into AI infrastructure plays like Seagate, and profit-taking after a 107% YTD rally. Analysts highlight that PLTR’s 332x dynamic PE and 115x price-to-sales ratio are unsustainable unless revenue growth accelerates beyond current 34% expectations. The stock’s pullback aligns with broader tech sector weakness, as Microsoft (MSFT) also fell 2.2% on concerns about AI margin pressures.

Tech Sector Volatility as Seagate Surpasses PLTR
While Palantir remains a top S&P 500 performer, Seagate’s 113% YTD gain underscores a shift in leadership. Seagate’s 528% EPS rating and AI storage demand contrast with PLTR’s 57% profit growth. The tech sector’s fragmentation—only three of the top 10 S&P 500 stocks are pure tech—highlights PLTR’s vulnerability as investors pivot to hardware enablers of AI infrastructure.

Options and ETF Strategies for Navigating PLTR’s Volatility

PLTR’s technicals suggest a short-term bearish bias, with key support at $145 and resistance at $160. The stock’s 52-week low of $32.47 remains distant, but near-term volatility favors options strategies. Two top options from the chain:

PLTR at a Crossroads: Watch for $145 Support and Sector Shifts
Palantir’s 3% decline tests its ability to sustain momentum amid valuation skepticism and sector rotation. The stock’s 21.59 RSI and bearish MACD suggest further consolidation, but a break below $145 could trigger deeper selling. Investors should monitor Microsoft’s (-2.2%) performance as a sector barometer and Seagate’s AI storage demand as a potential catalyst for PLTR’s AI platform. Act now: Short-term traders may consider PLTR20250912P145 for a bearish play, while longs should wait for a confirmed rebound above $150.
