Qualcomm's U.S. stocks rose more than 2% pre-market, Huang Renxun shouted: Go buy their stocks.

Before the US stock market opened, Qualcomm rose more than 2%, thanks to NVIDIA CEO Huang Renxun publicly suggesting investors to buy shares of this chip manufacturer. Huang Renxun praised Qualcomm's performance in the mobile device field during his remarks. "We are not very good at the mobile device business, and we don't need to delve into it," Huang Renxun added when talking about Qualcomm, "I think they are doing a great job." He bluntly said, "Go buy their stock." "There's no problem with that. I recommend stocks from other companies all day. It's a good thing to help peers, and we should feel happy when we see others succeed."
