Regime first: VIX 18.3 and rising 5% on the week, SPY still up 1.5% over five sessions but today's tape is screaming rotation — XLK down 2.65%, XLY down 1.23%, defensives (XLV, XLP) bid. That is textbook risk-off rotation under the hood of an index that hasn't broken yet. We're 13 days past FOMC and 36 days from the next one, which means the back-month leg of any calendar (July expiry) will straddle that meeting. Calendars don't like vol expansion in the front month relative to the back, and they really don't like gap moves through the strike. Now look at what's already on the book: I'm already long an IWM put calendar opened today. Adding a QQQ put calendar is not diversification — it's doubling the same bet. Both are long-vega, short-gamma, neutral-to-slightly-bearish structures that profit if the underlying drifts toward strike with vol holding up. QQQ and IWM are not the same index, but in a defensive-rotation tape they will be correlated on the downside, and the vol surface response will be correlated too. This is one position dressed up as two. Worst case on this specific structure is at this strike level, about 1.6% of cash. Standalone that's survivable. But stacked on top of the IWM calendar and the TMO bear call, the portfolio's combined worst-case is now meaningfully concentrated in 'short-gamma, neutral-to-bearish, vol-sensitive' exposure. If QQQ gaps down 5% on a tech-led selloff next week, the K=700 strike (currently roughly 5% OTM from QQQ proxy levels) gets blown through, front-month gamma dominates, and the calendar collapses well before the back-month vega catches up. The 0.66 p_profit assumes an orderly drift; the regime is telling me drift isn't the base case right now. The edge described — at this strike level EV on at this strike level capital with strong liquidity — is real on paper, but the EV calculation almost certainly underweights the fat left tail in a rotation regime with rising VIX. And I have no closed-trade track record yet to calibrate whether my calendar scoring is even honest. First rule when you don't know your own edge: don't stack correlated bets. Confidence is high that passing is correct here. What I'd want before reconsidering: either close the IWM calendar first, or wait for VIX to stabilize and the tech tape to stop bleeding so the structure isn't fighting the regime on day one.
