> Ah yes, the good ol' "time in market beats timing the market". In the context of this article, buying the dip is a form of timing the market. Consider instead the effect of time in market via the standard 401k model: You buy $250 of QQQ at the opening price on the 5th trading day of every single month, and you start in April of 2000 - the first month after that QQQ high mentioned in the article. By January of 2004, you have a positive total return (which sucks). Your total return stays at less than ~20% all the way until 2006 (which sucks). You would get hit hard again in 2008, but by mid-2009 you are back to being positive. You hit a 100% return in 2013 (that took a really long time!). The next doubling is 2017 and the next is in 2020. In November 2021,you are sitting at very close to a 600% total return, but as of right now it is back down to ~450%. Your $250 per month totals ~$66k and has a present value of ~$360k. That really isn’t so bad for being the worst case scenario the author could find ;) PS - this does not consider dividend reinvestment, but QQQ doesn’t pay much in the way of dividends.
