Shorting puts as a way to buy a stock into a decline is a nice sounding strategy but in practice I'm finding its pretty flawed. What happened to BRKB shows to me the flaw I didn't anticipate. So I shorted a bunch of puts, the stock declined to the strike price and even bellow. I didn't buy enough of the stock because I was already pretty exposed through the puts. The stock recovered and the puts (the ones that I kept) are going to expire worthless. But the problem is that I lost the chance to buy the stock like I wanted (I only got in a small stake). I wanted to have been exercised but the dip recovered before the expiration
One could say, just short half of the notional stake that you wanted to have and wait to buy the shares with the other half. Well, I'm not sure doing half of a mistake is a good idea
I would be making a nice profit now with BKRB at $137. Now I don't want to buy it, not in this enviroment. I will probably have to wait a few months for another VIX spike to add more
