If ETF funds are so good, why do so few people buy them?

I do not recommend buying ETFs; they rise very slowly and have large pullbacks. Once you chase high prices, it is completely hopeless to recover. Moreover, the exact value of an ETF cannot be calculated, and the holding experience is very poor.

Unless this ETF is rising 95% of the time and has continued driving forces to rise, do not buy the ETF.

ETFs are just a package of leading stocks and junk stocks. The A-shares have always been in a bear market, and junk stocks generally keep falling to ST. So why not just buy more stable leading stocks directly?

Updated on 10.18, I found the discussion in the comments very lively, and I've changed my mind a bit. Some ETFs are still quite recommended, such as the S&P series, the Hong Kong stock dividend series, the commodity series (excluding energy and chemical ETFs), and the Chinese bond series. We can't generalize.

Regarding industry ETFs, my view remains: not good.
