Nvidia Post-Earnings

Real Money Stock of the Day Nvidia (NVDA - Get Report) posted earnings that beat expectations after the bell Thursday.

Adjusted earnings in Nvidia's first quarter were 88 cents a share, beating forecasts by 30 cents. Revenue fell to $2.22 billion from $3.21 billion a year ago and came in roughly in-line with forecasts of $2.2 billion. Gaming revenue of $1.06 billion beat forecasts, while data center revenue declined 10% from a year earlier to $664 million.

Last night, right before the earnings call, shares of Nvidia were up nearly 7%. However, after the call started and CFO Collette Kress disclosed that Nvidia would be going from yearly guidance to quarterly guidance, shares were only up around 2%.

Pinterest (PINS) failed to impress investors when the company released its first earnings report.

The adjusted loss in the quarter narrowed to 32 cents a share from 38 cents a year earlier but was wider than forecasts that called for a loss of 11 cents.

Revenue in the first quarter rose 54% to $202 million, ahead of analysts' estimates of $200.7 million.

The company promptly fell 15% in after-hours trading Thursday night.
