It’s useless to time the market. Who can do that successfully? All you can say is that the valuations don’t seem right or too high and then you sell everything.
The easiest thing to do is just not buy any new stocks during times like these. I thought the market was too high in May of this year, but I held on and my portfolio went up by 20%! Buffett is right about timing the market.
Just keep a load of cash on hand and buy during the next correction. Assuming of course, that you want to keep your assetts denominated in dollars.
