How the markets moved today

S&P 500 (^GSPC +2.91%) advanced 2.92% to finish Tuesday at 6,529, while the Nasdaq Composite (^IXIC +3.83%) climbed 3.83% to close at 21,590.63.

What this means for investors

Nvidia shares rose after news of a $2 billion investment and an expanded AI infrastructure partnership with Marvell Technology, reinforcing demand across AI networking and custom chip development. The move comes even as Nvidia’s size and prior gains keep expectations high, highlighting how incremental infrastructure deals can still drive the stock despite its large market value.

The rebound follows a roughly 20% pullback from recent highs, which has helped reset positioning and attract buyers, while Nvidia’s central role in AI data center buildouts continues to support sentiment. The Marvell partnership also points to continued expansion across the AI supply chain beyond GPUs, thereby broadening the demand narrative. Investors will be watching whether similar large-scale infrastructure deals continue to emerge in the near term to sustain momentum following the recent pullback.
