Stock Market Today: Dow jumps 1,000 points, S&P 500 and Nasdaq surge after last week’s selloff; Nvidia stock drops as CEO probe launched: live updates

Stocks closed sharply higher Monday, with the Dow jumping 1,000 points as the S&P 500 and Nasdaq surged, rebounding from last week's selloff. Nvidia shares moved the opposite way, retreating after news that a probe of the company's CEO had been launched.

The split tape stands out. Broad indexes rallied hard while one of the market's most closely watched single names fell, which suggests the Nvidia decline stayed contained to the stock rather than dragging on the wider tape. That reading is interpretation, not a stated cause: the headline links the Nvidia drop to the CEO probe, but the source offers no detail on the probe's scope, and none on what drove the index rally beyond last week's selloff.

The Dow's 1,000-point gain gives the session a clear scale marker. A move of that size, following a down week, points to dip-buying or a relief bounce across large-cap names. The Nasdaq and S&P 500 surge confirms the strength was not confined to blue chips.

For Nvidia holders, the divergence matters most. The stock fell into a market that was ripping higher, so the weakness is name-specific and tied to the headline risk of the CEO probe.
