Stock Market Today: Dow Jumps 900 Points as Market Rebounds from Last Week’s Sell-Off; Nvidia Shares Plunge as Company Investigates CEO Huang

Stocks ripped higher Monday as the Dow Jones Industrial Average jumped 900 points, rebounding from steep losses the prior week. Nvidia went the other way: shares plunged after news that the company is investigating CEO Huang, raising uncertainty about the chipmaker's leadership.

The split tape matters. Broad indexes are surging on a relief bounce after last week's sell-off, while Nvidia is sliding on a company-specific governance headline. The market is rewarding risk broadly but punishing the one name where the top executive is under internal scrutiny.

Interpretation: a 900-point Dow move after a week of heavy losses reads as a snapback, and Nvidia's decline despite that bid suggests the leadership news is being priced as a distinct, idiosyncratic risk rather than part of the broader tape. When a stock falls into a rally this strong, sellers are clearly in control of that name.

The source provides no detail on the nature of the investigation, its scope, or any timeline, so the size of the eventual impact is unknowable from what has been reported. That uncertainty itself is the driver: markets tend to discount unresolved leadership questions until facts emerge.
