I recently retired so I'm no longer buying but I did get unbelievably lucky. Right after all this started I was in the process of rolling over my self employment 401k into a schwab ira which went directly into their money market account.
Initially before it transitioned my 401k went down about $200,000 but after that it would've gone down another $400,000 (estimated). I feel as if I made $400,000. I'm gonna wait about a month then I'll put it back into an S&P index fund.
In the meantime I've got a stock portfolio I call my 'play money'. I strongly disagree with day trading but when the market goes up 1,000 pts it looks like a good time to sell then buy back the next day when it will inevitably go down.
