S&P 500 Wobbles as Nvidia Selloff Rattles AI Trade

The S&P 500's recent strength is being tested as Nvidia shares slide sharply, reviving debate over whether the broader AI trade is finally unwinding or if this is simple pre-earnings jitters. Given Nvidia's outsized weight in the index, its moves are disproportionately dictating the tape for the entire benchmark.

Traders are parsing whether this is a healthy rotation out of crowded mega-cap tech positions or the start of a deeper de-rating. With the S&P 500 heavily concentrated in a handful of AI-linked names, any sustained weakness in semiconductor sentiment threatens to drag the index lower even if breadth elsewhere holds up.

Volatility around the Nvidia print will likely set the tone for index direction into the next session, with dip-buyers watching closely for signs of stabilization.
