Stocks are probably going to decrease a bit more, is it a good idea to sell now and buy at the end of the dip when they are lower?

I'm wondering, considering companies will eventually recover and stocks will increase is it a good idea to sell my stocks 5,76% negative plus a little amount of taxes, to buy when they're the lowest with all this WW3 vibes.

I'll still get my money back and would avoid exposure to further loss now, what do you guys think? Thanks in advance
