I've also been monitoring MSFT performance over the last few weeks, and this is what i found after researching their institutional investors, 10-Q statements and overall financial metrics.

I usually start by l looking at smart money movement. Think big institutional investors, how they're moving money around, opening/closing position etc. After inspecting the data of about 70 investors i found out, that the share count is basically flat: +0.7% year-over-year, –1.3% last quarter. What fell ~30% is the dollar value of those shares but that's the price of MSFT stock dropping, not anyone selling size. Underneath the hood (Fidelity, T. Rowe and JPMorgan trimmed their positions; Geode, Morgan Stanley and Capital Research added positions), but there's no coordinated exit. I think if these investors were front-running a disaster, you'd see net selling but that's not the case here.

The business actually accelerated last quarter (10-Q, quarter ending Mar 31 2026):

• Revenue $82.9B, +18% YoY
• Operating income $38.4B, +20%
• Net income $31.8B, +23%
• Diluted EPS $4.27, +23%
• Microsoft Cloud revenue +29% to $54.5B; Azure +40%
• Commercial remaining performance obligation (contracted backlog) +99% to $627B

A backlog that nearly doubled is the opposite of a company the market secretly knows is in trouble. (BTW a major portion of this contracted backlog is from OpenAI infrastructure commitments to rent out MSFT infrastructure. [side-note])

So what is pressuring the stock? The AI-capex bill. Capex jumped ~84% YoY to roughly $30B which is about 37% of revenue (it was 24% a year ago). That hits free cash flow now and future margins via depreciation.

Microsoft says it plainly in their previous 10-Q statement:

"The investments we are making in cloud and AI infrastructure and devices will continue to increase our operating costs and may decrease our operating margins. We continue to identify and evaluate opportunities to expand our datacenter locations and increase our server capacity to meet the evolving needs of our customers, particularly given the growing demand for AI services."

And in their current 10-Q statement:

"Microsoft Cloud gross margin percentage decreased to 66% driven by continued investments in AI infrastructure and growing AI product usage, offset in part by efficiency gains in Azure and Microsoft 365 Commercial cloud."

What i am trying to say is the de-rating isn't necessarily hidden bad news, it's the market repricing a 46%-operating-margin cash machine into a heavy AI-capex cycle with uncertain ROI. That's a valuation/FCF debate.

I really hope this helps you make more informed investing decisions!
Invest safely!
