Thanks for the help Sonia ! Don't know how this helps. Account is tits, maybe you should have published this earlier, would saved a lot of trouble...
Interesting but the difference in vol is more due to their stupid liquidation algo, the switch is static
The difference between Oct. and Dec. is not stationary, Dickey Fuller of order 3 shows it is highly "correlated" to the direction of the underlying which explains (partially) how it is weak when the market comes down
It is, but he would have been marked down on net liq on the prem (Dec/Oct value). Wouldn't have increased his haircut. it would have prob improved with CT lower. There is a lot more to the position than the Oct/Nov long switch. Vols rallied 8-10 pts into his short vol in other CT-positions. It's not my place to talk about his book beyond that comment. There is vol of vol upside in CT.
