Some awesome feedback here. Just to touch a few points:
Intrinsic/Extrinsic: If we are going with options that have a delta value of 1 there should be no cost for buying the option (granted usually it hovers around .96 -.98 but sometimes you can get options at 1.0).
Expiring Worthless: The option can expire worthless but that means (with Delta 1 options) you lost the same amount that you would have lost if you were holding the underlying instrument. Technically you could then just buy the stock at this lower price and still control the same amount of stocks as you would have were you to go with buying the stocks directly.
I.e.:
Stock @ 100 -> 50 (50$ Loss)
Option @ 50, Delta 1, Strike @ 50: Stock goes to 50, option expires worthless (50$ loss)
Same loss in both situations. However, the 50$ saved from buying the option can be used to buy the stock at 50$, therefore you would control the same amount at the end of the period.
Additional strategies: Yes, there are lots of other strategies: Some risky, some less so. But without going into these *very* interesting discussions, I just want to loop back to the main point:
Why not always invest in deep in the money delta 1 options instead of buying the underlying stock?
So far I've seen ways to improve upon this, but none that really say : Here's a major downside.
