Volatility skew

Discussion in 'Options' started by DeltaDelta, Oct 1, 2005.

  1. OK , Sle. You are right , I came here to learn more , especially from members like you and Riskarb. I do similar to what you described above : buying the event ATM , but selling ITM (2.5 points deep for both calls and puts) next, non event month(if IV is inflated , of course). I find it to be the highest gain_per-combo.
    Take care

    Never mind that !

    Hang onto your seat, SLE is about to explain how to structure a positive gamma AND positive theta At the same time ! This is hot stuff....

    Hopefully !

    That's not that hard to do. I did it all the time last year. It's simply a function of a steep smile.

    Oy vey. You are selling the guts. Which in case you were not aware of is the same thing synthetically as selling the more liquid and better priced strangle. Obviously you have NOT read Natenburg. Better learn your synthetics before you start trading for real.

    All you have to do is look for real sharp skews going into earnings. I use to play them with ratio spreads, typically 1 x 3 spreads. Now keep in mind, this is one of the flaws in the BS model. The reason I say flaw is because your position is not going to behave the way your greeks say they will.

    For example. Take a $100 stock. Say you buy one Oct 110 call and sell three Oct 115 calls calls for a .20 credit. This position could show that you are long gamma and long theta. The reason is because you are selling the 115 calls which are higher up the smile. That extra premium is what is giving you long theta. But in reality, it's an illusion. I say that because you will not be earning this theta every day like you think.

    Just like in the previous example I gave with the 32.50 stock, those 115 calls are going to stay bid and as time goes by, the vol will actually INCREASE! This is expected. Therefore, that long theta you have is not really theta at all. You will only earn this juice after the earnings report. But on paper, your position will be long gamma and long theta. The long gamma is coming from the fact that you are long the 110 calls on a front month option. Since gamma tails off as you go further out of the money, the 115 calls are picking up very little gamma.

    Anyway, I could go on forever about this. This is why you need to know your greeks forwards and backwards. Because many times, they are very misleading. You need to know how your options are priced and why they are priced that way. Just looking at your net greeks is not going to cut it. BTW, you aren't going to find a lot of these in this low vol environment. Usually on stocks like GOOG and CME you will find them now because of the sharp skews going into earnings.

    I just find it funny that you obviously did not know that. There is no reason to ever trade the guts over the strangle unless the guts are priced better then their synthetic which 99.9% of the time they are not. I hate to say it bro, but that post of yours outed yourself. You should have left it alone after your first few posts. Ever heard of the saying, "it's better to be quiet and make everyone think you are a fool then to open your mouth and prove it"? :D

    I don't see how a ratio write could make you positive gamma AND positive Theta, regardless of any smile / skew.

    sle ?

    BTW, I know my greeks inside out, back to front, and upside down.

    Think about it. Where is the gamma located in any option? Where is the skew? What does that skew represent? Think about the gamma curvature.
