Buying NVDA call contracts.

Nvidia Corp. (NVDA) reported disappointing earnings after the market closed last night. The stock was off sharply in after-hours trading.

But today, the stock is up nearly 3% as investors step in and buy.

This is a good indication that investors have already priced in the negative news for this company and any future surprises are likely to be positive.

NVDA is rebounding from a key support area — and could have a ways to run as investors rebuild positions.
