According to a report by Sina Finance on July 19, Cathie Wood, founder of ARK Investment, said that Nvidia is currently a "common" artificial intelligence (AI) bet, and she is buying other stocks that are expected to benefit from AI technology. It is reported that Wood has received extra attention after liquidating the Nvidia position held by the flagship fund ARK Innovation ETF (ARKK) in January. This operation has caused the fund to miss a large part of its strong gains this year. Now, Wood says, Nvidia has soared, leaving many other companies that would benefit from AI behind. "We've basically redeployed our investments into other AI stocks that weren't as high profile, and Nvidia is the usual bet right now," she said. Wood also said ARKK’s largest holding, Tesla, is “the largest investment opportunity in AI.” In an interview, she said her best new investment idea was Teradyne Inc. , a company that designs semiconductor testing products and services.
