Option Focus | Microsoft’s $7.37 Million Sale of 510 Calls Expiring 2026 Signals Bearish Stance, Despite $3.61 Million Debit Combo with Downside Protection

Option Witch07:01

Microsoft closed at $481.63, up 0.27%.

Microsoft’s options market showed a complex picture, with a $7.37 million sale of 510 calls expiring in 2026 signaling a bearish stance, while a separate $3.61 million debit combo involving the same 510 call and downside puts suggested a more nuanced, protected directional bet. The session’s aggregate large-trade flow leaned mildly bearish, with bearish premium of $7.73 million slightly outweighing bullish flow of $6.67 million.

Options Indicators

MSFT’s implied volatility is 27.99%, and with an IV percentile of 41.04%, current option volatility sits in a neutral range rather than at an extreme. That suggests MSFT options are neither especially cheap nor especially expensive at the moment, with pricing broadly around typical levels relative to its own recent history. The IV/HV ratio of 0.48 further indicates implied volatility is running below historical volatility, implying current premiums are not stretched. The Call/Put volume ratio is 1.87.

Large Trades

A three-leg combination with a net debit of $3.61 million stands out as a structured, longer-dated directional position for the October 16, 2026 expiration. The trade buys the 510.0 call, sells the 420.0 put, and buys the 390.0 put, with all legs tied to the same maturity, making it a CALL+PUT combination established for a net debit rather than premium collection. With MSFT referenced at 481.63, the 510.0 call is out-of-the-money, the 420.0 put is out-of-the-money, and the 390.0 put is also out-of-the-money. Strategically, this looks like a directional bet with embedded downside protection: the short 420.0 put helps finance the structure, while the long 390.0 put caps part of the downside risk, leaving the trade positioned to benefit from upside while still maintaining a defined hedging element below the short put strike.

A bearish single-leg call sale worth $7.37 million was the largest outright trade of the day, with 7,000 contracts sold on the 510.0 call expiring October 16, 2026. Since the strike sits above the 481.63 reference price, the option is out-of-the-money, and the seller appears to be expressing a view that MSFT is unlikely to rally decisively above that level by expiration, or at least is using elevated upside premium as an opportunity to collect income. Overall sentiment across all large trades was modestly bearish, with bullish flow totaling $6.67 million versus bearish flow of $7.73 million, leaving a net bearish difference of $1.06 million. The directional read is therefore mildly negative: despite the presence of one sizable structured upside-oriented debit combination, the largest outright print was a substantial out-of-the-money call sale, and the aggregate flow shows bearish premium slightly outweighing bullish activity.

Strategy Reference

For a low assignment probability, a seller could consider the 540.0 call or higher in the same October 2026 cycle; alternatively, a bear call spread such as selling the 510.0 call and buying the 530.0 call would cap margin requirements while maintaining a defined-risk bearish view.
