A futures hedge won't be effective. She's trading extremely convex stuff and so her deltas will be changing too much. On top of that she won't be compensated for this chop because the initial premiums are so low.
I think she's been successful because she's probably actually very prudent. She's an old lady who was an accountant - she's probably actually very good at risk management. she's not your typical elitetrader cowboy who thinks he's smarter than everyone else.
I was responding to the guy who was discussing about options liquidity drying up up at expiration date and that might cause run in SPX moves to cross the strike of the short options hence loss of profit. So you can hedge that out with an algo with futures.
Actually if you watch some of her interviews, she explains she is an accountant and very quantitative and technical in nature when she started. But over time became more a go on gut instincts and strategy kind of trader.
As for risk management, anyone selling naked options in the form of strangles, and not even iron condors with defined limited risk, has no risk management here. You can argue she is a superior trader. And clearly if she can pull it off she is a good trader (i.e. buying and selling of securities to time markets). But there is no risk management being that leveraged and taking on naked short options positions like that. Her other risk management technique as far as I can tell is not going 100% all in. I think she mentions being 70%(?) max at any given time. So she can take the odd blow.
Her risk management seems to be as follows:
-Selling both calls & puts to create short strangles. So at least she is not betting directionally, which means premium from one end will at least soften blow to the other if there is a run on her in one direction.
-Not fully maxing out margin room
-Talked about VIX bull call spreads as a potential hedge trade but mentioned she has not been doing that recently in one interview.
None of that stuff is really a very legit hedge, except maybe the call spread on the VIX to hedge out some of the vega risk.
But clearly this strategy of selling tail risk premium is losing effectiveness. The VIX is at all time lows. And while she continues to be in the business of selling premiums, the profits must be dwindling compared to years with higher volatility. And if volatility picks up again, she is at real risk of vega really picking up with her short options too (on both sides of puts/calls no less). Of course she is probably not a one trick pony. Maybe she will flip sides to be long options. Like how Paulson bet against real estate before and now bet on it. Play both sides.
