Technical
Over 5,240 trading days, missing just the 10 best cut the yearly return from +11.1% to +6.9%. 6 of the 10 best days came within two weeks of one of the 10 worst.
Plain English
The best days tend to arrive in the middle of the worst stretches, so getting out after a scary drop often means missing the bounce too.
