Regime first: VIX 18 and rising 3.8% over a week with SPY still grinding higher is the 'index up, vol up' signature — money rotating, defensives (XLU, XLF, XLRE) getting sold while tech leads. That's a tape where realized vol can expand under the surface even though the headline index looks calm. We're 35 days from the next FOMC, so this iron fly's June expiry will live through at least one Fed meeting and a full earnings cycle for QCOM. IV regime is flagged 'extreme' on the name, which means the premium looks fat but it's fat for a reason. Now the setup. An iron butterfly with shorts pinned at 215 is a bet QCOM sits roughly on a dime for 36 days. Probability of profit is 0.33 — the model is telling me this trade loses two out of three times. The $312 EV is mechanically a function of the wide wings collecting rich premium in extreme IV, but EV in a short-gamma structure assumes the vol surface is priced fairly and the underlying behaves. On a single-name semi heading into a vol expansion regime, neither assumption is one I want to lean on. Iron flies at-the-money are the most gamma-sensitive structure in the book; any 3-4% move in QCOM (utterly normal for a semi) and you're at or near max loss. Worst case is $133.88, which is 0.45% of cash — trivial in isolation. That's not why I'm passing. I'm passing because the book is already heavily short-vol/short-gamma: TMO bear call, ASML bear call, MU bear call (three short-call-spread semis/quality names), WMT BWB, MRK BWB, IWM put calendar. Six positions, and at least five of them want vol to stay contained or compress. Adding a seventh short-premium trade — and an iron fly at that, the purest short-gamma expression — into a rising-VIX tape is concentration, not diversification. One vol shock prints losses across the entire book simultaneously. Also worth noting: I have zero closed trades and no realized P&L to calibrate against. I'm flying blind on whether my current short-vol stack is actually working in this regime. Stacking another correlated bet before I've seen a single position resolve is exactly the behavior that turns a good paper run into a bad one. Confidence is high on the pass. What I'd want before reconsidering: at least two of the existing short-vol positions closed at or near target so I can see the book breathe, or VIX rolling back under 16 to confirm the vol uptick was noise.
