To be fair, you don't know why the OP isn't posting. Maybe he is on BLM land and hasn't been able to respond? But to be honest, the way the OP is day trading, it would be impossible for you to verify anything he claims, anyway. The OP could come and post here this evening that he's up 6,000% due to a few great moves. How would you know the wiser since you don't know the details and timing of his buys/sells as they are happening (like most day traders, he only posts after the fact), nor the composition of his portfolio?
If you want to know how the current market conditions are affecting an investor's portfolio, I can tell you that I am down significantly. I am down something like 25%. Use your imagination about how much money we are talking about for portfolios of different sizes. The bigger your portfolio, the more significant the drop in terms of dollars.
As for how this one investor is handling the extreme market fluctuations, I can tell you that I am watching with great interest, but I am keeping my hands off of the wheel. As Warren Buffet once quipped, "Benign neglect, bordering on sloth, remains the hallmark of our investment process." Why such equanimity? Because, you see, losses aren't losses until you realize those losses, i.e. until you sell your shares. The same goes for gains. If you stay put and do nothing while others are frantically selling off, the market will eventually bottom. And then it will eventually come back.
Day traders (and gamblers in general) try to time this movement in order to make huge profits. The problem is that you have to get two very difficult decisions correct: when to get out, and when to get back in. Day traders mostly get it wrong and mostly lose money. Some lose their shirts.
Investors, on the other hand, ride out the fluctuation. We have seen this movie before. If you had done NOTHING after the drop in 2008 (neither selling nor buying), the market recovery began in earnest in April-ish 2009, and then it was off to the races for a long, sustained bull market run. In other words, investors kept their shirts. They did better than keep their shirts; they enjoyed the whole ride up. It's what allowed me to retire early at 40.
And this current market condition, too, shall pass. And frankly, I am doubly-unconcerned about the current market condition because I am not even tapping into my portfolio for another year or two, as I am living off of cash reserves. That's a loooong time to see how this current condition plays out.
