Microsoft CFO Amy Hood sold 3,387 Microsoft shares on Oct. 13, 2026 at $544.80 per share, for a total value of about $1.85 million. The filing indicates the sale was made under a pre-scheduled Rule 10b5-1 trading plan, which is a written plan that allows insiders to trade at set times or under set conditions, helping separate the decision to sell from day-to-day news. This trade matters because Hood is Microsoft’s Chief Financial Officer, a senior executive role with broad visibility into the company’s financial performance, capital allocation, and reporting. Investors often watch CFO transactions closely for signals about management’s confidence, but 10b5-1 plan sales are generally viewed as more routine since they’re arranged in advance and can be used for diversification, taxes, or liquidity needs. Over the past 30 days, this appears to be the only reported insider transaction at Microsoft. With no cluster of insider selling or buying in the same period, the activity looks isolated rather than part of a broader pattern.
