Thanks. Very, very interesting trading strategy. Can you explain a bit more about how volatility will affect this position? Let's look at some different scenarios with a couple of weeks having past (i.e. when we get to about Sept 12th):
1 - Vol is unchanged. Looks like you will be showing profits within a range of about 760 to 830. Not bad. But, you will show massive profits on a break below 600 or above 905.
2 - Vol is up 5%. Showing profits above 780 and massive profits below 615 and above about 850. As vol increases, your vega increases, I assume this is because you have positive vomma? Can you please confirm?
3 - Vol is down 5%. Showing profits between 745 and 845. Massive profits below 595 or above 915. As vol decreases, your vega decreases, I assume this is because you have positive vomma? Can you please confirm?
4 - Vol is up 25% due to a tail event. You are profitable within any range with profits increasing exponentially below about 670.
Very interesting strategy indeed, and I do love the fat tail protection. I have a couple of questions in addition to the ones above if you don't mind.
a) What are the downsides to this strategy? Obviously there is huge upside in the case of a fat tail event, but what can hurt this strategy? What is your worst scenario?
b) What's your plan for managing the trade? Adjustments, stop loss, profit target etc.
c) Do you have any criteria for trade entry, or is this something that you put on each month no matter what? Does the current vol levels determine how much tail protection you buy?
d) Anything else i'm missing?
Thanks very much for sharing and providing advice.
Since tail
Yes, the goal is to maintain a positive vomma. I stress test the trade by adding/subtracting vol, price and add time. The trade will usually start off with a slightly neg theta but this is not a concern. Neutralizing vega is the key.
My first adjustment, if you want to call it that, is adding/doubling the size of the trade, so it'll have a similar profile but with different strikes since the market is always moving.
I start taking it down a couple weeks or so prior to expiration or when the opportunity to close a few shorts at a time makes sense.
I like the 10 point spread on the call side and 20 on the puts. There is no magic to back ratios only that it is a much safer trade than iron condors.
Adjustments or additional trades are done after I give the trade some time to breathe and get an idea on direction. There are many adjustments to mention.
Try putting some on in your paper acccount to get a feel for them. Good luck.
