why wouldn't everyone buy a deep itm option and keep the rest in cash. for example right now apple is at 134.16 buy a 120 strike that expires in a month that is trading at 14. keep the other 12000 in cash. if apple shoots up u have all the upside and if it crashes tomorrow to 120 u might still have 3 dollars premium as the farther down it goes the the more the delta decreases, and the max loss is 1400.
yes, i know i am not the genius that thought of this first. but this is fairly simple and i don't see a downside to this. can someone tell me the drawbacks?
obviously this strategy is best to do when the bid ask on the option is not to wide.
as shown in ajacobsons post the option is closer to 15 dollars. So you are paying almost a dollar over the current price of apple ever month if you wanted to hold the same position.
the options pricing accounts for the cost of funds in the leverage opportunity. It also accounts for gamma risk (the fact that the option might be still worth three if the stock falls to 120).
there’s no free lunch.
