Nvidia's selloff on November 12 was deep enough to drag the entire S&P 500 into the red, making the stock's recovery one of the more consequential intraday moves of the session. Dip-buyers stepped in with enough conviction to erase more than half of Nvidia's loss on the day, and the broader index followed suit, turning positive.

A move that began as a broad market selloff was unwound within hours, suggesting that buyers had been waiting and treated the decline as an entry point.

Nvidia carries enough index weight that its direction can bend the S&P 500's daily performance on its own. When a stock of that size recaptures losses at this pace, it tends to shift sentiment across the technology sector and beyond.

The situation remained in motion at the time of The Kobeissi Letter's post, with Nvidia having recovered more than half of its intraday loss but not yet a full recovery. Traders following the session closely would have been watching whether that momentum continued into the close or faded as the afternoon wore on.
