After two straight down sessions to start September, Wall Street's rebound on September 2 was led in large part by technology stocks tied to artificial intelligence, with Nvidia shares climbing 3.12% on the day.
Nvidia was the single biggest contributor to the Dow's 295 point gain that day, ahead of American Express, up 1.84%, and Walt Disney, up 1.74%. Coverage of the session described it plainly: Wall Street rebounded after a three session decline, supported by renewed buying in AI related technology stocks, while Asian markets opened the following morning on steadier footing as a result.
The move is notable partly because of how the week had started. On September 1, technology shares had actually been a drag on the market, with the Information Technology sector of the S&P 500 falling 1.6% as investors rotated away from riskier assets amid Middle East tensions and rising bond yields. The reversal just a day later, with AI linked names doing much of the work to pull indexes back up, shows how central this small group of large technology and semiconductor companies has become to the overall direction of US stock indexes this year.
For everyday investors, the practical takeaway is that a handful of AI focused companies, Nvidia chief among them, continue to have an outsized effect on whether a broad market index goes up or down on any given day, for better or worse depending on the day.
Traders will be watching whether AI related buying can continue to offset pressure from higher bond yields and Middle East related uncertainty heading into Friday's jobs report.
Why does Nvidia have such a big effect on the overall stock market?
Nvidia is one of the largest companies by market value and central to the artificial intelligence trade, so its share price swings can move broad indexes like the Dow and S&P 500 significantly.
