What I mean by paying to hold a collar (even a no cost collar) is that as price moves up on the underlying assets and away from your put strike. ?.
If the SPX approached the short call strike, one could roll the collar up. How much that cost would depend on how close it was to expiration. I think that it would be minor, compared to locking in another 5% of portfolio gain. That's the trade off. The ET option trader's wet dream is that after doing so, the market collapses and in additon to the ~5% put protection from the collar, that previous, near worthless set of puts also comes into play and the downside becomes a winner since you have double the protection, at least below the lower put strike. Yeh, unlikely but a nice fantasy that occasionally come true when near worthless long options come back to life.
As for shorting calls on stocks while buying puts on index, couldn't you get level 4 and do "naked" calls in one account backed by the stocks in the managed account?.
I have Level 4 so naked calls isn't a problem. I just wonder if that approach introduces the issue of stock specific news creating an additional problem, namely one stock zooms up, say due to a very good earnings announcement, yet the portfolio goes up minimally. Now I have a call loss without the associated 5% portfolio appreciation (my initial tentative collar distance premise).
I think the answer here is a blend of all of the above. But you'd basically need to have the exit strategy in stone from jump.
If I utilied an index collar. I think the management would be reasonably similar to what I do when defending or booking gains with a single equity and attached options (or a vertical). To the downside, get outta Dodge or roll the long puts down and sell more call premium if defending. To the upside, roll the entire collar up. I think increased vols would not be much of an issue to the upside.
For example, I have seen great results on the VIX ratio spreads, but I've given a lot back trying to figure them out. I just rest orders to sell when they hit a certain threshold now, and would have been ragingly profitable had I started like that--but as of now, it's running a loss. I'm also not sure how large of the VIX ratios I'd be comfortable with.
When you figure it out, post a Cliff Notes version here for me.
