Honestly, the best think to do with this bear market, and I can bet most of the real traders will do this.
If you can afford it, best thing to do is max out your yearly contribution to your 401k when it drops lower. I think the max is something like 23k for the year.
I know myself, will absolutely NOT put 23k into a pinky. That's me though, best thing is dump it all in your retirement funds when Wallstreet is bleeding.
