The advice I have heard is if you think there will be a significant drop in the market you liquidate all your holdings while they are still high and then rebuy when the price is low. Granted this is a gamble though, if you’re wrong then you just sold all your stock and are no longer participating in the market plus you need to pay capital gains tax
Did you hear this advice from 100 broke people or one lucky schmuck?
This is significantly safer than shorting that some people here suggest.
You can't lose money sitting on cash. While when shorting your potential loss is infinite.
Mistiming the market is losing out on potential gains, which is losing money compared to sitting on cash. Cash doesn't grow.
Most people are best off investing in index funds and forgetting about it for 10+ years.
