Resist the urge to sell everything?

$AMC Entertainment(AMC.US)$ $Jim Cramer on Wednesday warned investors against selling off all their holdings, even as the markets continue to roil.

“No matter how scared you get, most people aren’t nimble enough to get out of this market and then get back in again at a good price. That’s why it’s a mistake to sell everything even as the market’s gotten more difficult,” the “Mad Money” host said.

I know that even if an investor plans to sell everything and reenter the market later, nailing down the right timing will be incredibly tough.
