Microsoft shares closed at $450.24 on Friday, up 5.45%, as strong momentum in the stock fueled a surge in options activity. Large block trades were concentrated in near-dated call options, with one transaction involving nearly $9.5 million worth of out-of-the-money (OTM) calls at the $455 strike, highlighting a broadly bullish tone in the options market.
Options Metrics
As of May 30, Microsoft's implied volatility (IV) stood at 26.05%, while its IV Percentile was 51.0%.
The reading places volatility in a broadly neutral range, suggesting current option premiums are neither significantly cheap nor expensive relative to historical levels. In other words, the market's expectations for future price swings remain broadly in line with historical norms.
Meanwhile, the call-to-put volume ratio reached 4.13, indicating a strong preference for bullish positioning among options traders, consistent with Microsoft's recent share-price strength.
Block Trade Activity
Over the past two trading sessions, large options flows were dominated by call purchases, with net bullish premium flow totaling approximately $14.96 million, signaling expectations for further upside in the near term.
The most notable trade involved the June 26, 2026 $455 call, an out-of-the-money contract that attracted 9,353 contracts of buying activity, representing roughly $9.45 million in premium traded. The size of the transaction suggests a high-conviction leveraged bet on continued gains in Microsoft's stock.

In addition to the aggressive OTM positioning, traders also accumulated substantial amounts of in-the-money calls, including the June 26, 2026 $440 call and the June 5, 2026 $435 call. Combined premium on these bullish trades exceeded $11.6 million, reflecting a more conservative approach to expressing upside expectations.

Diverging Positioning in Longer-Dated Calls
Activity in longer-dated August contracts revealed a more mixed outlook.
The August 21, 2026 $480 call saw significant two-way flow:
Approximately 4,000 contracts were sold, representing about $6.1 million in premium, a trade that could reflect premium-harvesting strategies or expectations that the stock will remain below the strike price.
At the same time, 1,732 contracts were purchased, totaling roughly $2.65 million, indicating that some traders continue to position for a breakout above $480 over a longer time horizon.
The opposing flows suggest investors remain divided on Microsoft's ability to extend its rally beyond the $480 level in the coming months.
Strategy Watch
For options sellers seeking defined opportunities, the concentration of activity around the $480 strike highlights a key area of market debate.
One approach is selling out-of-the-money August calls near the $480 strike to collect premium, particularly for investors who believe the stock may struggle to sustain gains above that level. However, such strategies carry potentially unlimited upside risk if the shares continue to rally.
For traders looking to limit risk exposure, a bull call spread may offer a more balanced alternative. This strategy involves purchasing a lower-strike call while simultaneously selling a higher-strike call, reducing upfront costs while defining both maximum profit and maximum loss.
Overall, recent options flow points to a market that remains constructive on Microsoft's near-term prospects, with aggressive call buying supporting the bullish narrative, even as longer-dated positioning reflects uncertainty over how far the rally can extend.
