IV trader, I agree with your analysis, If I convert into B-fly. I will have no loss even if the stock trades out of my range 120-90. I may have some probability to make some money. I am expecting a small correction in SPX/ISRG.
Offset the strangle for $33.00. Vols have dropped 200bp, but the delta was beginning to become a concern.
PF Dissection: A 1x3 PF is simply a synthetic 1x3 ratio-write [spot x option]. The natural PF is an advantage in index markets w/o an futures contract, such as the SOX. To replicate the ratio write [PF] in such an index would require a two-way synthetic in the options: SOX put-skew ratio write: Short atm call/Long atm put x Short 3 otm puts SOX put-skew PF: Short itm call/Short 2 otm puts [same-strike] Reduces the 3-way synthetic trade to a 2-way. Obviously in futures options it's preferable to trade the 1x3 ratio write with futures/options. Applicable in equity options with put skew in issues with restricted shorts, or for anyone preferring to trade options-only. PF synthetic = futures x 3 otm puts[calls] 1x3 ratio synthetic = PF Skewed Index PF: Short itm call [short futures/short put synth] x short 2 otm puts [same-strike]
ICE: Reported today. Stock is up slightly, but the June 65 combo hasn't lost more than 300bp in vol. Looks like a nice trade here at $11.00 and 58% vol on the sale.
ISRG: Rolling over here after a couple failed attempts to trade >130. Sold the June 120 combo. Don't have fills in front of me.
Riskarb, what do you think about a strangle on GOOGster? Short 10 Jun450 Calls, Short 10 Jun390 Puts for a credit of 20? B.E. is between 370 and 470...?
A 420 straddle would be preferable if you're looking to carry those long deltas. I wouldn't suggest it unless you're bullish on GOOG to 420 a share.
