MSFT Bull Put Credit Spread — 2026-08-21

MSFT (Microsoft Corporation - Common Stock) shows bullish unusual options activity: $59419K of buyer-initiated unusual call flow (96% call-dominant) detected across near-term expirations, with a peak vol/OI ratio of 0.7x on the 460 call. We fade this by SELLING premium on the other side: the trade profits from time decay as long as MSFT stays above $475 through expiration. IV rank is 46 (moderate) — rather than sell naked premium at this IV, this is defined as a bull put credit spread (short $475 / long $470) so max loss is capped. Sell the $475 / buy the $470 put bull put credit spread expiring 2026-08-21 (18 DTE) for a net credit of $1.43 ($143 per spread). Breakeven at $473.57; net delta 0.05.

Underlying: MSFT @ ~$488.61 | 2026-08-21 (18 DTE) | Net credit (entry): ~$143 per spread. Use limit orders at the mid or slightly better.

ENTRY: Sell the $475 / buy the $470 put credit spread expiring 2026-08-21 (18 DTE) as ONE order at a LIMIT of the mid or better — target credit $143 on a $5 -wide spread. IV rank 46 is moderate — credit is workable but define risk and don't oversize. Don't leg in. Gamma: dealer gamma is POSITIVE (vol-suppressing) — spot tends to pin/mean-revert, so a briefly-tested strike often reverts; don't over-adjust on the first touch; put wall (support) at $460; call wall (resistance) at $500. | TAKE PROFIT: Buy the spread back to LOCK IN gains at ~50% of the $143 max credit (close near $71 remaining). Also close on TIME: exit around 21 DTE regardless of P&L to sidestep the late-cycle gamma/pin risk near MSFT's short strike(s) — currently 18 DTE, so plan the exit 0 day(s) out. Defined risk — max loss $358, so let it run to ~50% rather than scalping tiny. | IF TESTED: If MSFT tests the $475 short put (delta ~0.30) or the loss reaches ~$285 (≈2× credit), roll the WHOLE spread DOWN and OUT ~7–14 days for a net credit — the lone-vertical play is roll-down-and-out or close (there's no untested side to roll in until you add a call spread). Treat a close below the $460 put wall as the hard trigger to act (the pin support has failed). If price knifes past the $470 long put, the spread is at/near max loss ($358) — take it rather than hoping. Breakeven $473.57. | MAXIMIZE: Winning cleanly above $475? Let theta close it toward 50%. To improve it, roll the spread UP toward the money in the next cycle for a fatter credit once most of this credit is banked, or add a bear call spread above the market to convert into an iron condor and double the premium if the flow turns two-sided.
