Or you can be a Boglehead and in general not try to pick individual stocks and not try to time the market: https://www.bogleheads.org/wiki/Getting_started
"Bogleheads® emphasize regular saving, broad diversification, and sticking to one's investment plan regardless of market conditions. We follow a small number of simple investment principles that have been shown over time to produce risk-adjusted returns far greater than those achieved by the average investor. They have been further distilled and explained in thousands of posts on the forum. ..."
That said, sometimes people get lucky so YMMV. And the Boglehead philosophy and success (following by Jack Bogle, the creator of the first Index fund) has been forged primarily over the last few decades of US markets and people can question if anything substantial might change and when. Always lots of discussion about such things on that web board.
