An S&P 500 ETF is highly regarded for its investment potential, endorsed by top investors like Warren Buffett and widely utilized by hedge funds. The index, which tracks 500 leading U.S. stocks, is updated quarterly by S&P Global to include top performers while removing underachievers. Historically, it has averaged a 9% annual return, but in recent years, it has been outperformed by the Invesco QQQ Trust, which follows the Nasdaq-100 index of major non-financial companies.
