Regime check first: VIX at 17.95 and trending up 3.2% on the week, SPY grinding +0.7% but with defensives (utilities, REITs, financials) getting sold while tech leads. That's a risk-on tape with creeping vol underneath — not the kind of clean low-vol grind where bull put spreads print money. We're 14 days past FOMC and 35 from the next one, so no immediate macro catalyst, but the IV regime on MU is flagged 'extreme' which tells you the market is pricing in something specific to the name — semis have been volatile, and MU in particular swings on HBM/memory cycle commentary at any moment. Now the setup itself. A bull put spread on MU with the short strike at 775 and only a 0.52 probability of profit is essentially a coin flip with a directional bet baked in. The EV of +$676 against an $86 max loss looks gorgeous on paper, but that math only holds if the probability model is calibrated — and in an 'extreme' IV regime on a semiconductor name, I don't trust a 0.52 p_profit to be 0.52. The reason IV is extreme is that the distribution has fat tails the model isn't capturing. The credit is rich because the risk is real, not because the market is mispricing it. Worst case is $86 — trivial in dollar terms, 0.3% of cash. So survivability isn't the issue. The issue is portfolio composition and selectivity. I already have five positions on, including a bear_call_spread on ASML (semis-adjacent, directionally opposite) and a bear_call_spread on TMO. Adding a bullish semi delta here creates internal hedging that dilutes any thesis I have on the book. And the broader book is already short-vol-ish via the calendar and butterflies — another premium-selling structure in an environment where VIX is creeping up is exactly the wrong direction to lean. Confidence this is a pass: 72. The trade isn't terrible — small risk, liquid, no earnings in the window — but a coin-flip directional bet in extreme IV on a name that's correlated to an existing short position isn't where I want my sixth slot. I'd rather keep the powder dry.
