Quote from rew:
You'd have to sell a heck of a lot of premium to make 3300% in two years. When you sell an option short you must either set a substantial amount of money aside as margin or must hedge, which for most trades still requires some margin, and reduces your profits. It's not as though you can just sell $80,000 worth of OTM puts or calls in an account with $100,000 in it, no matter how confident you are that they're all going to expire worthless. Also if you don't hedge the day will come when you blow up, guaranteed. In 2008 a lot of put sellers blew up real good.
Retail traders who are very good at it do well if they consistently make 40% a year selling option premium. A truly exceptional trader might make 100% a year (although most of those 10%-a-month guys blow up). I just can't see any way anyone is going to make 3300% in two years selling option premium.
My guess is that the 3300% guy was long on some OTM options and was very, very lucky (or very, very astute at guessing market direction, in which case, he should start a hedge fund).
Well, I don't know how you arrive at long otm options when I stated he only went short gamma/vega. He was only in defined-risk; so no, he didn't trade any positions requiring variation margin.
I know a guy in Germany who turned a 10k account into 10 million over 6 years with zero outside funds or additions of any kind. He traded nothing but short gamma.
Short gamma (and vega) can obviously be traded defined-risk.
