Here is a clean, concise rephrased version of the full news piece:

U.S. stocks rose on Wednesday, snapping a four-day tech-led decline as investors awaited Nvidia’s upcoming earnings report.

The S&P 500 gained 0.38% to close at 6,642.16, while the Nasdaq Composite added 0.59% to finish at 22,564.23. The Dow Jones Industrial Average advanced 47 points, or 0.1%, ending the day at 46,138.77.

Alphabet climbed about 3% to a fresh record high, fueled by optimism surrounding its newly unveiled AI model, Gemini 3. Nvidia — another member of the “Magnificent Seven” — jumped roughly 3% ahead of its third-quarter results due after the close. Analysts broadly expect the index heavyweight to beat Wall Street forecasts and project robust revenue growth driven by strong demand for its AI chips and infrastructure.

Still, the bar is high: recent profit-taking in tech reflects growing concerns that the AI boom has pushed valuations for Nvidia and other hyperscalers to stretched levels. On Tuesday, the Dow and S&P 500 logged their fourth straight declines, the S&P’s longest losing streak since August, while the Nasdaq posted its fifth loss in six sessions. Bitcoin briefly slipped below $90,000 before rebounding, and gold recovered from a one-week low.
