The SPDR S&P 500 Index Fund (SPY), which holds the crown of the largest Global ETF, has once again missed the title of "the favorite symbol of retail investors in the US stock market" this year. After being overtaken by Tesla last year, it was once again severely crushed by the AI leader NVIDIA over the past year. According to Statistics from research firm Vanda Research, as of the 17th of this month, retail investors have net bought a total of 29.8 billion dollars worth of NVIDIA Stocks this year, nearly twice that of the SPY Fund (net purchase of 15.3 billion dollars). Ranked third is Tesla with 14.7 billion dollars, which still has the chance to increase further. The QQQ, which tracks the NASDAQ 100 Index, ranks fourth with 9.8 billion dollars, followed closely by another AI computing concept stock, AMD, also at 9.8 billion dollars.
