Shortstrangle
Rolling: NVDA August 19th 190 Short Call to 160... for a 6.10 credit and selling the 180 call for 2.52.
Comments: Inverting my original short strangle to a 5-wide (165P/160C) and selling the 180 call to flatten net delta. Total credits collected of 17.48. Resulting delta/theta 8.27/29.95 with a downside break even of 147.52.
This underlying ... has been pesky. It's possible that taking on shares and selling call against would've been the better way to go, since it ripped up to 190 at one point (only to subsequently give it all up), which would have afforded me an opportunity to bail on the position.
Opening: QQQ August 19th 250/331 Short Strangle... for a 5.05 credit.
Comments: 5.05 ($505) credit on buying power of 29.26 ($2926); 17.3% ROC as a function of buying power effect; 8.6% at 50% max. Currently the highest IVR/IV broad market ETF on the board at 71/35. Went a little wider here than usual (13 delta both sides) to accommodate more whip. Delta/theta .45/14.52.
Rolling: XBI July 15th 65C/75P to August 70/86... for a 9.88 debit.
Comments: As with my IWM trade, paying a debit to uninvert this setup, free up buying power, and turn it into a higher POP (Probability of Profit) setup. I had collected a total of 11.65 in credits up to this point, so I'm still net credit by 1.77 after doing this, but with a smaller buying power footprint and with "delta/theta happy" metrics at -2.66/8.70. Like the IWM trade, however, it's under water: it's currently marking at 5.42. I had a brief opportunity to take it off for a .70 loss, but it decided to move too much ... .
Rolling: IWM July 22nd 167.5/172 to August 5th 158/187.5... for a 6.04 debit.
Comments: Rolling out and paying a debit here that is smaller than total credits collected to reduce buying power effect. Up to this point, I'd collected a total of 8.39 in credits, so I'm still net credit on the setup by 2.35, but it's currently marking at 4.57 or so, so I'm down 2.22 on the position at this point. The setup, however, is now "delta/theta happy" at -4.03/12.39 and isn't being such a buying power pig.
