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