MSFT: five straight sessions of same-direction call premium with IV rank at 21

Alot of unusual options activity is one big print that means nothing.

What I look for on a swing timeframe is persistence — net premium leaning the same way session after session. That's positioning being built, not a single hedge.

# MSFT right now:

5 for 5 sessions of net call buying, +$129.2M cumulative net premium, call/put skew 2.13x. Open interest up 1.7% over that stretch, so it's being held overnight, not day-traded off.

**Why options instead of shares:** IV rank is 21. Persistent bullish flow into cheap vol means I'm not paying up for the thesis. Same flow at IV rank 60+ and the trade is already priced — I skip it. Price is above the 20 and 50-day, so nothing here is countertrend.

**Structure:** 46 DTE, 0.56 delta. Earnings are \~65 days out, deliberately outside the window. A binary event inside a flow-based thesis kills the read the moment the print lands.

**Risk:** stop at −30% on premium, first target \~+110%. About 3.7:1, my minimum for a multi-day options swing.

**Invalidation:** the persistence breaks. Two consecutive sessions of negative net premium and the reason I'm in is gone — I don't wait for the stop to tell me. That's the real exit, not a price level.

**The obvious criticism, made by me first:** flow doesn't tell you who's on the other side. A 2.13x call skew fits someone building a bullish position and fits someone hedging a short equally well. I treat it as a filter that stacks with trend and cheap vol, not a signal on its own.

Anyone else running flow persistence instead of single-print alerts? Curious where you set the lookback — five sessions is what I settled on, not from any real optimization.
