There’s a very small chance you are going to time the bottom. The only way to time the bottom is to keep buying by dollar cost averaging. For most of us, that’s probably the wisest course vs. actively moving money around and trying to time the market.
I do dollar cost averaging and have since the early 90s when I first heard the term mentioned on a radio investment advice show (mutual funds, then). It has served me well. Recently, I started to do this into a couple index funds of my own creation using Fidelity’s Solo FidFolio and Stocks By the Slice (fractional share) features.
