<h2 class="wp-block-heading"><strong>S&P 500 Worst Performers – November 2025 </strong></h2>
<p>November saw a broader shift in the market where investors rotated money out of high-flying “AI hype” stocks and into more defensive or undervalued sectors. This sector-wide cooling off added pressure to tech and AI-related stocks.</p>
<p>Super Micro was the worst performer in the S&P 500, dropping about 35% in November. The decline was driven by a combination of <a href="https://www.benzinga.com/markets/earnings/25/11/48638236/super-micro-computer-stock-tanks-after-q1-earnings-heres-why">disappointing first quarter results</a>, shrinking profit margins and long-standing concerns over its internal financial controls and corporate governance.</p>
<p>Oracle shares fell approximately 23% in November after a strong run-up earlier in the year driven by AI optimism. The stock faced a correction in November as sentiment shifted and investors became wary of the "circular" nature of <a href="https://www.benzinga.com/markets/equities/25/11/49109212/dan-ives-says-it-is-nvidias-world-and-everyone-else-is-paying-rent-predicts-massive-tech-rally-into-2026">massive AI deals </a>and investments. </p>
<p>Palantir stock was another notable victim of shifting AI sentiment and profit taking, falling more than 16% in November after shares had climbed by more than 150% earlier in 2025. </p>
