Sharing Duan Yongping's ultimate investment advice for making money: Close your eyes and buy the S&P 500, and eventually, you'll make money. Honestly, investing in U.S. stock ETFs doesn’t have to be complicated. Bet on the future of the U.S. economy with the S&P 500—stick to $VOO and $IVV. Large scale, low fees (0.03%), stable dividends (1.2%) that are higher than domestic bank deposit rates—holding these feels super solid. Believe in technology shaping the future? Go for the Nasdaq 100—focus on $QQQ and $QQQM. Great liquidity, low fees (0.15%-0.18%), dividends around 0.45%, and a top choice for long-term value growth. Ignore the noise, avoid off-brand picks, and hold onto these few—better than anything else.
