(Reuters) - Shares of Nvidia Corp reversed course after markets opened to gain about 2.5 percent on Tuesday after shortseller Citron Research said it has bought the chip designer’s stock.

"Citron buys $NVDA. This is the first time in 2 years stock offers an appealing risk-reward to investors. $NVDA still a player in AI and Data...will eat through inventory issue. We see $165 before we see 120," Citron said in a tweet here. Shares of the company, which were down as much as 8 percent earlier in the day, were trading at $147.75.
