Ok, I was ignoring the credit to keep it simple.
But then you are saying I could actually leverage the spread even more than 33:1???
Same with the naked put.
But the MASSIVE leverage gap between the 2 strategies, still remains similarly MASSIVE.
Correct?
Well they're not equivalent in delta-terms, but delta has various moments of convexity. The spread accumulates deltas much faster (higher gamma and +speed), making tao's argument moot, but that was not remotely my point.
If any of you are under the assumption that I give a fuck if you blow up, you're wrong (well, I don't want to see you blow-up). I am not trying to save anyone from themselves, the SEC IS DOING THAT.
The fact remains that most traders lever-up in spreads because by their nature they're DELIMITED bets. For the same reason pros will avoid a short backspread in favor of a fly, even if there is a ton of skew in the wing (think long fly, bear delta, index).
Another example. In OTC mkts in exotics it's almost always more favorable to trade the american DNT over the euro digital double. The digital double is a pick-em proposition at either KO, which is a bad position to be in, while the DNT is a total loss... but the DNT is 1/2 the debit of the 2x-digital. I'd rather take the discount from inception (or go much wider on the KOs at the equiv debit) than pray that spot trades one tick in my favor in the digital double at the KO.
