According to financial data provider Vanda Research, Nvidia has replaced Tesla as the stock with the largest net purchase by retail investors this year, reflecting investors' continued pursuit of the technology stock bull market. Compared with the popular representative of traditional index funds, the S&P 500 Index ETF, Nvidia's net inflow this year has almost doubled, reaching $29.8 billion, which is nearly nine times that of 2021. Marco Iachini, senior vice president of Vanda, said: "The fact is that Nvidia has stolen Tesla's thunder to some extent because its price increase is impressive." (Jinshi)
