How this view changed
- · Rating cut from High to Medium. Company news, 10 November 2026: Anthropic launched Claude Sheets, a spreadsheet that competes with Excel, alongside Claude Data and Claude Whiteboards; Microsoft shares fell as much as 3% intraday and closed down 2.2% at $533.16.
In the portfolio Since : −1.9% from the average price paid for its shares, 2.6 percentage points behind the S&P 500 from the minute it was bought. See the portfolio.
Why it was bought
Bought 10 November 2026, in the portfolio's opening purchases. The fact behind it, dated 28 October 2026: Fiscal 2027 Q1 results: revenue +19%, Azure +48% constant currency, Q2 Azure guided to 49–50%.
Price against the kill line
5.7% clear of its kill line on the 13 November 2026 close.
How to read this
The red mark is the price level of the published kill line: a close through it (a weekly close, on a weekly line) would prove the research note wrong on price. The dot is where the stock closed on 13 November 2026; a dot left of the mark has closed through its line.
The scale is stretched near the line, so close calls are easy to see. More than 8% from the line, the stock reads well clear, with a hollow dot to show the figure is off the drawn scale.
The kill line is the research note's own test. The portfolio sells on business facts, not on a price. How the portfolio decides
Three months against the kill line
Daily closes, to . Red: the kill line, a weekly close below $495.63, on record since 11 November 2026; only a weekly close settles it. The shares are up 9.3% since the close; the S&P 500 is down 2.1% over the same sessions. Figures in the note can cover a different window.
Kill line
A weekly close below $495.63, the 11 September 2026 close, which would put the shares back in their September range and erase the advance after the 28 October report. Azure growth below 47% excluding currency effects in the fiscal second quarter of 2027, or Microsoft guiding fiscal 2027 free cash flow negative, would also break the case.
The portfolio's case
Azure is compounding near 50% in constant currency (+48% in fiscal 2027 Q1, guided to 49–50%), with commercial remaining performance obligations of $677 billion up 73% and operating margin near 50%. Free cash flow fell 27% to $18.6 billion on $45.2 billion of quarterly capex including finance leases, and that worry has kept the stock behind the index for a year.
The portfolio sells if one of these comes true
- Fiscal 2027 Q2 Azure constant-currency growth below 47%, or Q3 Azure guidance below Q2's actual.
- Microsoft guides fiscal 2027 free cash flow negative, or commercial remaining performance obligations growth falls below 40%.
- OpenAI cuts or moves its committed Azure consumption, or Microsoft discloses a material OpenAI share of remaining performance obligations at risk.
It can also sell when that day's research finds the stock fully priced, for a clearly better use of the money, to limit risk in the portfolio, on the weekly review's plan, when a cash takeover pays the shares out or at the end set for a shorter trade when it was bought. A close through the kill line (on a weekly line, a weekly close) means the note's call is wrong: the note is re-read, and the portfolio reads the new note at its next decision. The price alone never sells.

This note mentions Anthropic, the company that makes Claude, the AI model that wrote it. The same method and sources apply as on every note. The conflict of interest, stated.
The thesis
Microsoft's shares are modestly more likely than not to lead the S&P 500 over the next three months. The reason is Azure: the cloud business grew 48% excluding currency effects in the September 2026 quarter, and Microsoft guides to 49–50% for the December quarter. The fiscal second-quarter 2027 report, expected in late January 2027, shows whether Azure delivers that pace.
The rating is Medium because the Azure figures are filed, recent and above expectations, and the shares have held near their 50-day moving average through two separate shocks. On 10 November Anthropic launched Claude Sheets, a spreadsheet aimed at Excel, and Microsoft fell 2.3% to $521.12 on 11 November while Benzinga reported the Nasdaq 100 up 2.8%. From 12 November to 14 November a global Microsoft 365 outage took down Outlook, Teams and Copilot for more than 24 hours, Digital Trends reported. The shares closed at $523.88 on 13 November, up from $523.00, in a session in which Benzinga reported the Nasdaq 100 down 1.7%.
The price already assumes a lot. At the 13 November close the shares trade at 27.3 times earnings and 11.1 times sales, with a 1.5% free-cash-flow yield, on figures filed to 28 October. Revenue grew 18.8% from a year earlier in the September quarter, to $92,279 million. Holding the multiple requires that growth to continue while capital spending turns into Azure revenue.
Bullish and bearish views on Microsoft Corporation
The bull case on Microsoft Corporation (MSFT), in brief: Azure beat and guided higher. The bear case: Anthropic opened a front against Excel.
Bull case
- Azure beat and guided higher. Azure grew 48% excluding currency effects against about 45% expected, investingLive reported on 28 October. Microsoft guided fiscal second-quarter revenue to $96.0–97.1 billion, above a $95.6 billion estimate, per Benzinga and SiliconANGLE.
- Filed growth and margins are strong. The 10-Q for the quarter ended 30 September 2026 shows revenue of $92,279 million, up 18.8% from a year earlier, and an operating margin of 49.8%, the highest of the last six quarters. Net income over the four quarters to 30 September was $142,631 million.
- Contracted demand keeps growing. Backlog stood at $683,000 million on 30 September 2026, up 71.6% from a year earlier, per the 10-Q. Deferred revenue rose 13.0% to $69,563 million.
- Demand still exceeds supply. Chief Financial Officer Amy Hood said on 28 October that demand keeps outrunning capacity, per SiliconANGLE. Nvidia guided its quarter to 25 October at $108.0 billion of revenue and reports on 17 November, per its own release.
- Microsoft owns part of the rival. Microsoft is among the investors in a $26 billion private placement tied to Anthropic's initial public offering, Investing.com reported on 10 November, citing Anthropic's filing.
- OpenAI is a large paying customer. Microsoft recorded $10.0 billion of revenue from commercial arrangements with OpenAI in the September quarter, about 11% of the total, The Next Web reported on 29 October from the quarterly filing.
Bear case
- Anthropic opened a front against Excel. Claude Sheets launched on 10 November with connectors that let Adobe, Atlassian and HubSpot run inside Claude, per Investing.com. Anthropic's Nasdaq debut is reported for 19 November, which would fund a direct competitor to Microsoft 365.
- The outage hit the core franchise. Exchange Online problems began around 11:17 a.m. Eastern time on 12 November and spread to Teams, Copilot, SharePoint and Intune, Digital Trends reported on 14 November. Microsoft traced it to an earlier network capacity upgrade exposed by a later network change. Benzinga reported on 13 November that Defender, Safe Links and Purview security tools were also disrupted.
- Spending is eating free cash flow. Capital spending was $135,921 million over the four quarters to 30 September 2026, leaving free cash flow of $59,957 million against operating cash flow of $195,878 million, per the 10-Q. Microsoft expects more than $50 billion of spending in the fiscal second quarter, The Next Web reported on 29 October.
- Microsoft borrowed $25 billion as spending rose. Microsoft sold $25.0 billion of senior notes in ten tranches maturing from 2028 to 2066, with fixed-rate tranches paying 4.850% to 6.350% (Form 8-K filed 4 November).
- OpenAI concentration is rising. Receivables from OpenAI rose to $7.2 billion at the end of September from $6.0 billion in June, per the quarterly filing as reported by The Next Web on 29 October.
- Third-party capacity is slipping. Business Insider reported on 4 November that Aterio's satellite analysis puts about 140 megawatts of a Microsoft-linked Nebius project at risk of slipping into 2027. Nebius fell 16.84% on 13 November on soft guidance and Microsoft data-center delays, Benzinga reported.
- UK regulators want conduct powers. The UK Competition and Markets Authority provisionally proposed strategic market status for Microsoft's business software, including Copilot, on 16 October, with a final decision due by February 2027, Resultsense reported.
Price setup
Microsoft closed at $523.88 on 13 November 2026. That is above the 50-day moving average of $519.0 and the 200-day moving average of $440.49, both as of the same close. The shares are up 9.3% over three months. They sit 6.3% below the 52-week intraday high of $559.15 set on 4 November, and far above the 52-week closing low of $352.83 on 25 June.
The Anthropic launch took the shares from $545.18 on 9 November to $521.12 on 11 November. They then held between $521 and $524 through the outage sessions of 12 November and 13. The 50-day average is the nearest level the case turns on: a run of closes under it would show the Anthropic and outage news weighing for longer than a news cycle, and a recovery toward the 4 November high would show the market looking through both to the January report. The kill line sits below the September closing range.
SEC Form 4 filings show Chief Marketing Officer Takeshi Numoto sold 5,000 shares at $531.00 on 10 November. Amy Hood sold 7,305 shares at an average $544.37 on 9 November and the same number at an average $545.42 on 13 October, both under a pre-arranged Rule 10b5-1 trading plan. Chief Executive Satya Nadella gifted 4,704 shares on 6 November. None of the filings since September reports an open-market purchase.
Catalysts ahead
- 17 November 2026: Microsoft Ignite conference, 17–20 November, Moscone Center, San Francisco. Shows whether Microsoft discloses Copilot agent usage or revenue after Anthropic's office-software launch, and how it addresses the 12–14 November outage with enterprise customers.
- 17 November 2026: Nvidia results for the quarter ended 25 October 2026, after the US close. Sets the tone for AI infrastructure spending after Nvidia's chief executive's exit, and tests whether Microsoft keeps trading apart from the AI hardware group.
- ~19 November 2026 (est.): Anthropic Nasdaq debut, with pricing reported for 18 November. Funds a direct competitor to Microsoft 365 and puts a public value on the Anthropic stake Microsoft is buying through the private placement.
- ~4 December 2026 (est.): Decision deadline for the voluntary buyout offer to about 60,000 employees. Uptake sets how far the program offsets rising depreciation from AI spending.
- ~27 January 2027 (est.): Fiscal second-quarter 2027 results. Shows whether Azure meets its 49–50% guidance, how backlog grows, whether spending runs above $50 billion, how OpenAI receivables move, and whether the outage cost any revenue.
- ~13 February 2027 (est.): UK Competition and Markets Authority final strategic market status decision on Microsoft business software. A final designation could impose conduct rules on bundling Copilot with Office and on access for rival AI tools.
What would change the view
A weekly close below $495.63, the 11 September 2026 close, which would put the shares back in their September range and erase the advance after the 28 October report. Azure growth below 47% excluding currency effects in the fiscal second quarter of 2027, or Microsoft guiding fiscal 2027 free cash flow negative, would also break the case.
The risks this note tracks, each with what would confirm it:
- Azure growth falls well short of its accelerated guidance. Confirmed by: Azure growth below 47% excluding currency effects in the fiscal second quarter of 2027 at the late-January report, or fiscal third-quarter Azure guidance below the fiscal second-quarter actual.
- Anthropic's office tools take share from Microsoft 365 and Copilot. Confirmed by: paid Microsoft 365 seat growth slowing below 5%, or Microsoft citing competitive pricing pressure in productivity software.
- The 12–14 November outage damages trust in Microsoft 365 and Copilot. Confirmed by: Microsoft disclosing material service credits or a revenue effect from the outage, or large customers or governments publicly moving workloads to rivals.
- OpenAI dependence turns into a credit or revenue problem. Confirmed by: OpenAI cutting or moving its committed Azure consumption, a reserve against OpenAI receivables, or Microsoft disclosing that a material OpenAI share of remaining performance obligations is at risk.
- Capital spending outruns revenue and cash generation. Confirmed by: Microsoft guiding fiscal 2027 free cash flow negative, or commercial remaining performance obligations growth falling below 40%.
- Giving up rented Oracle and neocloud capacity leaves Azure short of supply. Confirmed by: Microsoft attributing an Azure shortfall to capacity constraints, or more supplier delays like those IREN disclosed on 5 November 2026 and Nebius faced in November.
- A US ban on Chinese optical transceivers slows Microsoft's data-center buildout. Confirmed by: a federal rule barring new Chinese transceiver models without a broad exemption for hyperscale data centers.
- UK conduct rules limit Copilot bundling in Office. Confirmed by: a final strategic market status designation by February 2027 followed by proposed conduct requirements on Copilot defaults.
What it trades with
Microsoft has traded apart from the AI hardware group in the latest sessions. It fell on 11 November while the Nasdaq 100 rose 2.8% on a CoreWeave-led rally, and it closed higher on 13 November while AMD fell 10.5% and the Nasdaq 100 fell 1.7%, per Benzinga. The shares now respond more to news about AI software competition, chiefly Anthropic, than to chip-maker headlines.
The nearest links run through AI capacity. Nvidia's 17 November results set the tone for AI infrastructure spending after its chief executive's exit. Neocloud suppliers Nebius and IREN have reported delays on Microsoft-linked sites, and Bloomberg reported Microsoft pulling back from some neocloud deals. Alphabet and Amazon compete for the same cloud demand, and Anthropic's listing gives investors a direct way to own Microsoft's newest office-software rival.
