S&P 500 and Nasdaq Rise Ahead of Nvidia Results

Reuters reports the S&P 500 and Nasdaq Composite opened higher on May 20, 2026, driven by a rebound in chip stocks ahead of Nvidia's quarterly earnings, which investors view as a barometer for AI demand. Per Reuters, the S&P 500 rose 15.6 points, or 0.21%, to 7369.19, and the Nasdaq Composite rose 120.8 points, or 0.47%, to 25991.509 at the open. Reuters and the Economic Times note the Dow Jones Industrial Average slipped 15.0 points to 49348.83 at the same reporting point. The Globe and Mail reports slightly later levels: the S&P 500 at 7384.08, the Nasdaq at 26062.71, and the Dow at 49425.86.

The Globe and Mail lists individual chip-stock movers at the same session, including Marvell Technology up 8.13%, Micron Technology up 3.33%, and Nvidia up 0.73%. Reuters and the Economic Times also report investor caution about elevated U.S. Treasury yields, which market coverage flagged as a restraint on equity valuations even amid the chip-led rebound.

Market coverage frames Nvidia's quarterly report as a short-term demand signal for AI compute; observers often treat quarterly guidance and data-center revenue trends in chip earnings reports as leading indicators for cloud capex and supply-side demand for GPUs, accelerators, and memory.

For practitioners: Movements in chip stocks around Nvidia results matter to organizations managing procurement timing, budgeting for GPU capacity, and vendor selection. Industry observers note that strong results can support continued investment in AI infrastructure, while weaker-than-expected outcomes can tighten upgrade cycles and influence supplier stock performance.

Track Nvidia's reported revenue and any data-center or AI-specific guidance in the forthcoming results, memory and GPU pricing trends, and short-term shifts in Treasury yields. Market reaction in chip suppliers such as Marvell and Micron, which the Globe and Mail highlighted, will also signal how investors are interpreting the earnings for broader AI-infrastructure demand.
