Nvidia results beat estimates
Company sees continued demand growth ahead.
Chip giant Nvidia (NVDA) reported fourth-quarter results that beat Wall Street estimates on both revenue and earnings.
But shares were flat after hours before the company's conference call in part because its gross profit margin projection of 70.6% to 71% was lower than expected.
Shares closed up 3.7% at $131.28. They're down slightly on the year but up 67% from a year ago.
