Last week, Cathie Wood's Ark Invest made a series of high-profile portfolio moves focused on innovation and technology stocks. The most notable investments included significant purchases in Robinhood Markets (HOOD), Netflix (NFLX), and Baidu (BIDU), while the funds also made notable sales such as Shopify (SHOP) and Advanced Micro Devices (AMD) shares.

"The valuations [of Chinese tech stocks] are quite different. They're roughly half of what they are in the United States. We're very impressed at how quickly China is moving here," Ark Invest founder and CEO Cathie Wood mentioned in an interview earlier.
