Take two separate trading accounts. With account A, consistently sell deep out-the-money ES puts, month after month. With account B, consistently buy 3/4 as many deep out-the-money ES puts. You should make steady money most months, and then account A will go into a massive account debit during a market crash, with account B scoring huge gains. The person whose name account A is opened under, is actually a penniless hobo of no fixed abode. The brokerage has to eat the loss, the bum declares bankruptcy. Meanwhile, you have just retired off your gains in account B. You meet the tramp a year later once he's changed his name and moved to Pattaya, and hand him his 50% share of the winnings. What is the flaw in this strategy?
