CLOSE: GFIG Short Straddle +8.2%

After the volatility crush, I decided to close out this straddle and got a debit of $10.60.

I opened this straddle on 2/21/08 for credit of $13.15. So my net profit is 13.15-10.60= $2.55
My risk was $13.15 credit + $18.00 margin (20% of 90 strike)

2.55/(13.15+18.00) = 8.2% in 8 days
