Remember, most of the gains made in the stock market are made when the general ‘wisdom’ is to be in cash.
Market timers rarely do well in the market.
Chances are, you didn’t sell at the peak and chances are you won’t buy back in before quite a bit of the upward movement is past you.
If you wait until Piggs are saying it is safe to get back in, we’ll be long past any decent gains.
That’s why I don’t try and play that game. All my retirement positions are long positions and I have most of my money in ‘market’ positions with a few, generally strong, single stocks. I’m down quite a bit right now but since I’m still in the market, all the losses are ‘virtual’.
