US stock futures pointed to a modest rebound on Monday after last week's selloff, but Nvidia's premarket slide kept a lid on enthusiasm, especially for technology-heavy indexes. By early morning trading, Dow E-minis were up about 1.1%, while S&P 500 E-minis gained 0.7% and Nasdaq 100 E-minis lagged with a 0.4% rise, according to Reuters.
The split in futures performance is partly a reflection of index composition. The Dow Jones Industrial Average includes fewer high-growth tech names, while the Nasdaq 100 is heavily weighted toward mega-cap technology companies, particularly chipmakers that have powered the artificial intelligence (AI) boom. That means a stumble in a single large tech stock can have an outsized effect on the Nasdaq's direction.
Nvidia's leadership questions
Nvidia fell about 4.8% in premarket trading after reports surfaced of an internal investigation into whether CEO Jensen Huang was targeted by a foreign intelligence effort. The news raised fresh questions about leadership at a company that has become a bellwether for the AI trade.
Even though the investigation does not directly affect Nvidia's sales or profits, uncertainty about a central figure can make investors view the stock as riskier. That often shows up as a lower valuation multiple, meaning investors are willing to pay less for each dollar of expected earnings. For a stock trading at a premium because of its AI growth prospects, such concerns can trigger a sharper pullback.
The weakness spilled across the semiconductor sector. The Philadelphia Semiconductor Index recorded its biggest weekly loss since March 2025, and other chipmakers including Intel, Marvell Technology, and Qualcomm were down between 0.5% and 1% in premarket trading. This backdrop helps explain why Nasdaq-linked futures struggled to keep pace, even as some major AI buyers like Microsoft, Alphabet, and Meta were higher early on.
What it means for investors
For everyday investors, the key takeaway is that Nvidia's slide can limit how much the Nasdaq rebounds. When a mega-cap stock faces key-person uncertainty, investors typically demand a larger cushion for holding it, which can lead to multiple compression. Because Nvidia and other chipmakers are heavily weighted in growth-oriented indexes, that de-rating does not stay contained. Index funds and futures mechanically reflect the drop through market-cap weighting, so a decline in Nvidia pulls down the entire benchmark.
The result can be a narrower, more fragile rebound in Nasdaq-linked benchmarks compared with the Dow. The Dow's broader mix of industrial and financial stocks makes it less sensitive to a single tech giant's troubles. This divergence is a reminder that not all market rebounds are created equal.
For those with diversified portfolios, the episode underscores the importance of understanding how much of your exposure is tied to a handful of large technology names. A stock like Nvidia can move markets on its own, and events that seem distant from daily business—such as a leadership probe—can still ripple through your holdings.
Investors will likely watch for further developments in the Nvidia investigation and any impact on the broader AI supply chain. Nvidia's premarket drop has already stirred concerns among chip investors, and South Korean stocks fell earlier on similar worries. Meanwhile, chip stocks in Asia have shown some recovery on reassurances about supply, but the mood remains cautious.
In the coming days, market participants will be parsing any new information about the investigation and its potential implications for Nvidia's leadership and strategy. The company's role in the AI boom means any perceived instability at the top could have outsized effects on sentiment across the tech sector.
For now, the rebound on Wall Street looks tentative, with the Dow leading and the Nasdaq lagging. Whether that pattern holds will depend on how quickly investors can set aside the Nvidia-specific concerns and refocus on broader economic and earnings fundamentals.
