You really think you can make 50% return selling deep OTM puts?
You think it is that easy?
My point stands. You still don't understand it though
I never said it was that easy... I just pointed out that on a single trade/strategy you need to look at the capital used for setting that up. If you have portfolio margin, which I assume everyone has who trades actively with 100k in account, and use leverage... you should look at risk-adjusted return on used capital... basically the margin used.
So, if you use the full margin/leverage capability of your account... you can buy about 2mln worth of S&P500 and when you get your 7% return, its actually 7%x20=140% ... which is ridiculous, because no-one in their right mind would use that full leverage...
Same goes with OP's strategy, which is a credit spread and you hold margin for that... which is actually very low on a portfolio margin. If you have 100k in account and would do what OP wants to do but on a bigger scal... use the leverage you can, you can actually get to 50%. But the risk would be big...
Do you think option market makers only get 7% on their capital?? No... they tend to go for at least 20%.
There is no point in looking at a benchmark like S&P500 average return over the past 20 years when you leverage. And when you trade actively it's no point either...
I bet that most experience traders here who actively trade... (not 'invest') take a lot more then your 7%... because why bother otherwise.
So yes... I do understand... I'm just making a point that we're talking actively trading, usually with leverage and on margin. Not buy-hold over 20 years to get 7% on avg.
ps. why not use risk-free rate of returns as your benchmark... that's what now? 0.25%?? You're benchmarking apples with coconuts...
