I think it is a mistake to be 0% invested, I am about 70% invested and will probably reduce that to about 50% due to covered calls hitting.

Even if I was very sure a correction was coming I would be 10% invested.

I would probably only need a 5% correction to get up to 90% invested.

Of course 100% invested is not a limit I am willing to go to 300% invested using leverage, of course not at the moment.
