Nvidia shares fell 4.3 percent to $178.67 while the Nasdaq composite rose 2.7 percent to 25,253, signaling isolated weakness in the semiconductor giant.

The selloff follows reports of alleged China spy links involving advanced chip technology and potential national security vulnerabilities. These allegations could trigger expanded U.S. export controls on Nvidia's most powerful AI chips—already subject to strict restrictions on sales to China.

We view this as a material repricing of geopolitical risk. Nvidia's access to the Chinese market is a critical component of its long-term growth thesis. Any new restrictions would directly impact a substantial portion of global revenue.

Our fair value range is $160 to $170 under a heightened regulatory scenario—a 5 to 10 percent additional drop from current levels. This assumes expanded export restrictions or new U.S. sanctions materialize.

Nvidia's Feb. 14 earnings report will be the first test of these allegations' financial impact. Management guidance on China revenue, regulatory updates, and revised forecasts will determine near-term direction. We expect significant volatility and advise monitoring official statements from U.S. regulators and the company for specifics on chip export restrictions.
