Microsoft Options Market Skews Bullish as Call Volume Outpaces Puts by Over 2.5 to 1

Microsoft Corp. (MSFT) experienced unusually high options volume on Friday, with trading activity indicating strong bullish sentiment from market participants. By 12:40 PM EDT, over 1.11 million options contracts had changed hands, heavily weighted toward calls, according to market data reported by Investing.com.

Bullish Bets Dominate Trading

The most telling metric from the session was the call-to-put ratio, which stood at 2.53-to-1. This reflects 799,283 call contracts traded against 315,563 puts. This lopsided activity, which favors bets on the stock price rising, coincided with a 3.83% increase in Microsoft's share price to $517.02 as of 12:43 PM EDT.

Key Strikes Signal Near-Term Optimism

Analysis of the most active contracts reveals a focus on continued upward momentum in the short term. Significant activity was seen in out-of-the-money calls with a near-term expiration:

• $530 Call (Oct 16, 2026): This strike, roughly 2.5% above the current price, saw 3,659 contracts traded.
• $540 Call (Oct 16, 2026): Notably, the volume of 5,525 contracts nearly matched the existing open interest of 5,159, suggesting a significant amount of new bullish positions being established.
• $550 Call (Oct 16, 2026): This was the day's most active strike with 6,327 contracts traded, adding to a large pre-existing open interest of over 59,000 contracts.

This pattern suggests that traders are positioning for Microsoft's stock to clear the $530 to $550 range within the next three weeks.

Volatility and Hedging Activity

While call buying was dominant, put activity was concentrated far below the current stock price. Strikes at the $400 level for November and December expirations saw notable volume. These deep out-of-the-money puts, trading more than 22% below the stock's price, are typically interpreted as institutional investors buying protection, or tail-risk hedges, for large long-stock positions rather than outright bearish bets.

Furthermore, 3-month implied volatility rose to 29.62%. An increase in volatility during a strong rally indicates that the market is pricing in the potential for continued large price swings, rather than complacency. The overall options data points to a market focused on upside momentum, supported by institutional hedging.
