Not sure if OP meant literally sell, or just rebalance out of stocks. TBH I've been considering sliding over to all bonds for a time, since there is no tax event if funds stay in the account. But the numbers don't seem that high at the end of the day.

If you try to time the market and you sell at the exact peak you still have to time the market again and buy back at the correct bottom. If you miss either of these you're likely leaving long term performance on the table.
