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.

One analyst boosted his price target on Nvidia’s stock to a level that would imply a $5.7 trillion market cap, with the chip maker seemingly cleared to sell its H20 chip in China again.

The Nasdaq Composite posted its latest record finish today, supported by a jump in shares of heavyweight Nvidia, but the other Wall Street benchmarks dropped as a key inflation report and a flurry of bank earnings failed to excite investors.
