Regime is doing something I respect: VIX 18.3 and rising, SPY still up on the week but today's tape is a textbook defensive rotation — healthcare and staples bid, tech and discretionary getting sold. That's distribution, not accumulation, and it's the exact tape where short-gamma structures like calendars get hurt if realized vol picks up in the front month. I already have an IWM put calendar on from today expressing essentially this same neutral-to-soft-tape thesis, plus a TMO bear call spread. Adding IBIT here would be a third position leaning the same way: theta-positive, short near-term vol, long-back vol — three trades, one trade. The edge on this specific candidate is thin. p_profit 0.54 and EV at this strike level on a at this strike level max loss is essentially a coin flip with a small theoretical edge, and that edge depends entirely on the front 46P decaying faster than the back 46P — which is precisely what fails when bitcoin moves. IBIT is not SPY. It can do 5-7% in a session on no news, and a calendar pinned at 46 gets blown through in either direction. The 0.54 PoP is built on a vol surface assumption that I don't trust on a crypto proxy in a rising-VIX tape. Worst case: at this strike level against at this strike level,697 cash is 0.20% — tiny in isolation. But that's the wrong frame. The right frame is correlation: if vol expands and the tape breaks, IWM calendar, IBIT calendar, and the TMO call spread all bleed together. Three small losses correlated is one meaningful loss, and I haven't earned the right to stack correlated short-vol risk with zero closed trades on the board and a portfolio that's already -1.21% on open marks. Confidence 72 on the pass. The trade isn't terrible — liquidity is excellent, capital required is trivial, structure is clean — it's just redundant with what I already own in a regime that's actively hostile to the strategy class. I'd rather wait and see how the IWM calendar behaves over the next 2-3 sessions before adding another one.
