Regime first: VIX at 18 and trending up 3.8% over five days, SPY grinding higher but with defensives (XLU, XLF, XLRE) getting sold while tech leads — that's a risk-on tape with a creeping vol bid underneath. We're 14 days past FOMC and 35 out from the next, so we're in the meaty part of the inter-meeting window where realized vol typically picks up. QCOM specifically is flagged 'extreme' IV regime, which means something idiosyncratic is going on with that name's vol surface — semis have been whippy and QCOM has Apple-modem and China-handset overhangs that don't show up in a generic screener. Now the setup. An iron butterfly with strikes pinned at 215 and 36 DTE is a bet that QCOM sits right on 215 into mid-January. The screener says p_profit is 0.33 and EV is +$312 against $134 max loss. That EV number is doing a lot of work — it's only positive because the scoring model is taking credit for the fat premium that 'extreme IV' provides. But extreme IV exists for a reason: the market is pricing a wide distribution because the realized distribution has been or is expected to be wide. A short-ATM-straddle structure (which is what an iron fly is) in a high-IV single-name semi is exactly the trade that looks great on a spreadsheet and gets run over when the stock moves 8% on a sector rotation or a supply-chain headline. The 0.33 p_profit tells you the model itself doesn't think this lands. Portfolio context kills it anyway. I already have six positions open, four of which are short-vol or short-premium in character: two bear call spreads (TMO, ASML, MU — that's three actually), a put calendar on IWM, and two broken-wing butterflies. My book is already a giant short-gamma, short-vega blob. Adding a QCOM iron fly in extreme IV is correlation-stacking — if we get a vol expansion event in the next two weeks, every one of these positions bleeds simultaneously. The $134 max loss looks tiny in isolation (0.45% of cash), but the real risk is that it's the seventh short-vol position taking the same macro hit. Worst case on this specific ticket is the full $134, roughly 0.45% of the $29.6k cash — survivable in isolation. But the correlated worst case across the book if VIX spikes to 25 is meaningfully larger, and I don't get paid enough on this one to justify adding to that exposure. Confidence in passing: 80. I've passed 20 in a row, and I'm aware that pattern can become its own bias, but this particular candidate isn't the one to break the streak on — sub-50 p_profit, redundant exposure, extreme IV in a single-name semi heading into a vol-up tape.
