Wide Bid/Ask Spread Issue

    I own some ratio put protected stock (more long puts than stock). I want to keep the stock and roll my puts down 5 points, lowering my cost basis. However, the spread on the higher strike put is Holland Tunnel wide. I would like to know:

    1) Fair value of the June $45 put?

    XYZ = $39.15
    June 45p is $8.40 x $9.00
    June 45c is $$1.65 x $1.80
    Ex-div is 3/10 for 71 cents (two dividends by exp)

    Based on the midpoint of the $45 call, what is fair value of the $45 put? Can you also show me the calculation?

    2) This part is giving me a royal headache. As an alternative, if I place a combo spread order to roll the $45 puts down and MM won't give me the value calculated above (ignoring splitting the B/A on the $40p), I might be able to get around the wide $45p spread by using a long stock collar and transacting with the two options with much narrower spreads?

    IOW, the long 45p is equiv to shorting the stock and buying the Jun $45c. So if I sell the covered call and buy Jun $40 puts then I end up with initial shares, new shares, short $45c and long $40p and that's equivalent to rolling the $45p down. Is this correct? I realize that there's more slippage but if I can't roll directly, I still want to execute this. I have no problem tying up the cash, likely unwinding some of this when volatility settles down.

    Other suggestions welcome too.

    stock - strike = call -put

  3. Forget the math. It's all down to .......

    ....... how motivated of a buy/seller you are. If the trade is important then you accept the bid/ask - otherwise you can try the nickel-and-dime approach, which in most cases leads to a higher cost anyways.

    Find a correlated instrument with better spreads.

    Yap. As I said before: You know what you are doing. :thumbsup:

    Those bid/ask are nothing compared to some of the options I traded. It comes down to if you think the reward is >> the price you pay, you go for it. I just paid ask on xx contracts of call options which had a bid of $5.00 and a ask of $7.00. My opinion is even $7.00 is cheap.

    Who is right? Only time will tell. Since I paid for theta, time is not on my side but in this case it is my choice to go long instead of put write. :cool:

    One thing us mom and pop retails should always look at is who is doing the bid and ask. Usually the mid is not real if one side is a retail like us.

    I think not.

    Using your formula and using the midpoint of the call, the put would be worth be worth $7.57 (midpoint).

    And yet the put's quote is $8.40 x $9.00 . Houston, I think that we have a problem.

    What's missing from your incorrect answer is dividends and carry cost.

    At one point on Friday, the B/A spread was $1.20. I'm not motivated to trade at such prices, particularly when the aggregate position is fairly delta neutral hedged and a move in either direction doesn't slam me.

    Hi spindr0
    I just put an analysis up on our blog looking at this question: https://blog.orats.com/traders-complain-about-options-market-width-here-are-the-worst-offenders
    We also have a way to look at theoretical values to help with your trading.
    Let me know if you would like me to expand on these.
