If it plunges again, what would you do?

If it goes down another 370 in the next few days I would look at it as a gift and start to buy in. The market is waiting for a correction of about 500 points or so. I am only about 30% in right now. I would go another 40% in, and if there were another 300-500 points down I would go all in.

This is a knowledge seeking site not a what if game
So the dow goes down. The market has always gone up and down. we ride it for the long term and not sweat the small stuff

Nothing different than if it does not.

I'm moving to Mars.
