you know what else is a bad idea? Putting $80k into Virgin Galactic or Tesla calls at strategic moments in time. But I did both and now I'm sitting on more money in my toy account than my actively managed investment account. so maybe YMMV?
and no i don't recommend anyone doing what i did, but basic technical analysis said to sell [or buy puts] last week and with enough time watching markets you will know when an oversold relief rally is due [including mini rallies within overall downtrends]
