Robust demand for artificial-intelligence chips makes for attractive buying opportunities in several semiconductor stocks headed into earnings season, according to J.P. Morgan.

Nvidia said it has filed applications to resume selling H20 GPUs in China and has received assurances that licenses will be granted.

Nvidia took a $4.5 billion write-off in its latest quarter on unsold H20 chips that it was unable to repurpose for other markets. If sales of these high-volume chips to China resume, a reversal of this write-off could boost earnings.
