fair. have you tried Dollar Cost Averaging on individual stocks before?The reality is that buying an ETF on any exchange is essentially the same as buying the 3 to 5 largest weighted stocks within that ETF. If an investor isn't making money on those individual stocks, it's unlikely he'll make money on the ETF too. Conversely, if someone can profit from buying an S&P 500 ETF, whether in the long or short term, he should also be able to profit from, e.g. THE "big-7" stocks too, given that these stocks are over 80% correlated (possibly even more than 90%) with the ETF.
