Chris, give me a more specific example of what you are trying to do. When you are short a calendar you are taking in a credit. Your goal is to capture some of that credit. So If I sell the calendar for an 8 pt credit, I would like to buy it back for 7 1/2, 7 3/4 or 7 or even less if I can. If you do this spread correctly, you should never lose 2 pts. In fact I would call 2 pts a complete disaster. The only way you can lose 2 pts is if the stock opened flat the next day and the vol on the back month went vertical which would be awfully strange considering the stock opened flat. See you have two things here that are keeping you from losing a lot of money.
If the stock opens flat the next day then this is bad for your front month options which you are long. However, if that happens, and you sold really high vol on the back month then the premium on the back month should have imploded and kept you from losing money.
The other scenario, if the stock has really big news and lets say it gaps down 5 pts and the vol on the back month goes up therefore hurting your short vol position there, you would more then make up for that from the money you made by being long the front month premium.
So it's really odd that you could lose 2 pts on any spread. But give me specific numbers and I will look at it more carefully. Like I said before, you want to do as many of these as you can since a great majority of them will be even trades. You want to catch as many gaps as you can. I hope this helps.

Mav,
Thank you again for the detailed explanation.
let`s make MRVL - high volatility (one of the top on IVolatility list) on Tuesday had third quarter fiscal results released on Wednesday.
Following are quotes (bid/ask) on Tuesday close:
Call Nov40 - 275/295
Put Nov40 - 40/55
Call May40 - 730/770
Put May40 - 370/400
And quotes on Wednesday close:
Call Nov40 - 260/285
Put Nov40 - 65/80
Call May40 - 720/760
Put May40 - 390/420
So opening short calendar straddle on Tue would be $750 credit and closing on Wed comes to -$850 debit resulting in $100
(1 point) loss.
But once profits in this strategy are about fraction of the point, reward/risk ratio would not look impressive ?
Quote from Maverick74:
Chris,
A couple of things here. One, what did the stock do after they reported. Two, a one point loss is not that bad and the reward is not a qtr of a point. I have made over 4 to 6 pts in these trades and higher. I said most of the gains and losses would be small which is why I said you need to do a lot of them. Many of the gains will only be for 1/4 or 1/2 pt. And most of the losses will be for 1/4 to 1 point. But if you do enough of them the risk to reward ratio is very attractive. Also do you know how much the vol came in with mrvl? By the way, the prices you used were taken off the bids and offers which is fine but I always leg into these and get at least a nickel if not a dime off the bids and offers. So that already drops the loss to only .60 vs a dollar.

Thanks a lot to Mav and Hello Dollars for posting here. I called around to some brokerages and it looks like only Green Tree Trading allows spread margins for short back month/long front month. Are there any other ideas on how to play volatility implosion in the back months? Is putting a vertical spread on in the back month such a play? Should we do some sort of covered write?
