Microsoft ended the session at $516.17, up 3.66%.
Options flow showed unusually aggressive upside positioning, led by a $3.93 million in-the-money call purchase and a $2.20 million out-of-the-money call buy. Both trades were outright long calls rather than spreads or hedges, and the broader block tape leaned heavily bullish. Institutional-sized traders paid substantial premium for long-dated upside exposure across multiple strikes, signaling confidence that Microsoft can extend gains well beyond current levels over a longer horizon.

Options Indicators
Microsoft currently has an implied volatility (IV) of 30.31%, and with an IV percentile of 54.98%, its volatility is sitting in a neutral range rather than at an extreme. Combined with an IV/HV ratio of 1.42, the options market is pricing in volatility somewhat above recent realized movement, but overall option premiums do not appear especially cheap or especially expensive at current levels.
The Call/Put volume ratio is 2.39.
Large Trades
A call purchase worth $3.93 million was the largest displayed trade, with 1,154 contracts of the November 20, 2026 $500 call bought while the stock reference price stood at $516.17. This was an in-the-money long call, giving the buyer immediate intrinsic exposure along with additional upside participation through expiration. Strategically, this is a clearly bullish directional trade, suggesting the participant was willing to pay substantial premium for sustained upside exposure and potentially signaling confidence that MSFT can extend gains well beyond current levels over a longer-dated horizon.
A call purchase worth $2.20 million was the second highlighted trade, consisting of 2,000 contracts of the December 18, 2026 $575 call bought. With the strike above the $516.17 reference price, this was an out-of-the-money long call, making it a higher-convexity bullish position that requires further upside to become intrinsically valuable. The trade points to an investor positioning for a meaningful advance over time, using relatively farther-upside strikes to express a directional bullish view while keeping risk limited to the premium paid.
Overall, the large-trade flow in MSFT was decisively bullish. The biggest orders were both outright call buys, and the broader block activity also leaned heavily toward upside participation rather than defensive hedging, indicating that institutional-sized traders were more focused on capturing future appreciation than protecting against downside. Taken together, the figures suggest constructive market sentiment and a positive directional bias for MSFT, with traders showing willingness to commit capital to upside exposure across multiple expirations.
Strategy Reference
For a low assignment probability on the put side, a seller could consider an out-of-the-money short put below recent support, such as the December 2026 $450 or $460 strike, while traders who prefer not to post excessive margin may instead use a bull call spread like buying the $550 call and selling the $600 call in a longer-dated expiration to define risk and reduce upfront premium.
