My dad taught me that many (not all) gamblers blew the dough on winning and stayed mum on the losses. He had a card in his wallet with his weekly poker gains and losses. More losses than wins, but the wins were big enough to more than offset the losses. It was a 'friendly' game, mostly an excuse to drink and smoke cigars (my dad did neither). But I digress. The point is that one might consider netting losses before blowing the dough. And it can be hard to do in this kind of trading because it seems that success means avoiding the rare really bad trade. I knew two guys that thought they could trade for a living and both tell the same story...they made money on nearly every trade, or at least lost peanuts, but then there were those one or two trades that blew 6 months profit. Both went back to work for the man.
That sounds like a recency bias, they probably became overconfident after that long winning streak and blew past their position size limits. IIRC it's what killed LTCM during the 1998 Asian crisis (I remember that one well). If you hold the line on what you put into any one name, a few wipeouts won't matter if you score big on one or two. In my experience you can't avoid really bad trades if you want to have a chance at great returns-- you just dilute them with true diversification. My dad got burned badly on a Texas bank decades ago, so my hard limit on any initial outlay is 0.1% of net investments (most are far less; ESOP is my only exception).
I bought the single PUT BBBY 40 - Feb 5 for $6 on last Wed, Jan 27, when BBBY was trading around $50. The stock succumbed after that, and today it is down to about where it was before all this Gamestop short squeeze started.
Rather than wait till tomorrow when the option expires to see if I can get a few more bucks, I sold it today for $13.20. BBBY closed today at $27.01, so I sold the put at about its intrinsic value.
I'm diamond hands on BBBY, up a bit since I bought shares Christmas Eve of 2018. They paid five quarterly dividends until Covid hit. But paper hands on MGNI, I took the early surge this morning to close out what was "Rubicon Project" a year before I bought BBBY. Normally my positions are way more red than green but lately it's the other way around, although much of my green is "only just". The widespread large jumps in the sub-pennies (I re-buy these for a few bucks after taxloss harvesting and sort positions by %return ascending to serve as a constant reminder to obey my hard limit) I've never seen before and suggests speculative fever is especially hot now. IMO if this is FOMO, it screams late-stage bubble.
