Microsoft closed at USD 492.43, down 2.26%. Despite the daily decline, large options traders showed a strong bullish conviction. A massive $2.14 million in-the-money call purchase and a uniquely structured bullish calendar put spread, designed as a net-debit trade, led the activity. With total bullish flow reaching $4.97 million against zero bearish flow, institutional positioning appears firmly aligned with the expectation of further upside in MSFT shares.

Options Indicators

MSFT’s implied volatility is 27.95%, and with an IV percentile of 41.43%, current option volatility sits in a neutral range rather than an extreme. In other words, options are neither especially cheap nor notably expensive at current levels, with pricing appearing relatively balanced versus the stock’s recent volatility backdrop. The IV/HV ratio of 0.49 also suggests implied volatility is running below historical realized volatility, indicating the market is not assigning an aggressive premium to near-term option pricing. The Call/Put volume ratio is 1.10.

Large Trades

A bullish bull put spread with a net debit of $0.08 million was one of the two standout trades, built by buying the 500.0 put expiring on 2026-08-24 and selling the 500.0 put expiring on 2026-08-21, with both legs totaling 1,500 contracts and both strikes in the money versus the $492.43 reference price. Although labeled as a bull put spread, this is effectively a calendar-style bullish put structure across different expirations, and the key point is the trader paid a net debit rather than collecting premium. That suggests a directional bullish positioning with a timing component, likely seeking favorable value from the later-dated long put versus the shorter-dated short put, rather than a simple premium-collection trade.

A CALL buy worth $2.14 million was the other major trade, consisting of 2,000 contracts of the 490.0 call expiring on 2026-08-21. With the stock reference price at $492.43, the strike was in the money, making this a clearly bullish single-leg position with direct upside exposure. The use of in-the-money calls points to a trader seeking relatively high delta participation in further gains, which is typically a more assertive directional bet than buying far out-of-the-money upside lottery exposure.

Overall sentiment was decisively bullish, with total bullish large-trade flow at $4.97 million against bearish flow of $0.00 million, leaving a net difference of $4.97 million to the bullish side. The directional read is clearly positive: both highlighted trades expressed upside intent, with one using an in-the-money call purchase for straightforward bullish exposure and the other using a bullish multi-leg put structure that reflects constructive expectations with an expiration-spread element. Taken together, the large-trade activity suggests institutional positioning favored further strength in MSFT rather than hedging for downside.

Strategy Reference

For a neutral-to-bullish outlook with a lower margin requirement, an investor could consider selling a put credit spread, such as the 450/440 strike, where the short put sits well out of the money and carries a low probability of assignment given the current bullish flow.
