"Market timing doesn't always work"
Fixed that for you.
The only market timing that works long term is a continuous plan of regular investments and not turning into a mouth breathing panic monkey when the market does a downturn.
People on the intardnets who tell you that they can let you know their secret for making millions by timing them market for the low, low prices of $XX are lying.
Back in 2007 or so when the *expletive deleted*it hit the fan we had a couple of people here bail out of the markets, locking in their losses. Then they never re-entered the market. But did come back to whine about how much money they lost out on when the markets rebounded.
At the same time I watch my accounts lose between 75-80% of their overall value. It was rough to watch, but I doubled down, upped my contributions as much as I could, and quit obsessing over the numbers.
I'll retire in a few years as a multimillionaire.
