From each company's latest annual SEC filing. Fiscal years can end on different dates.
State Street (STT) is the larger business by reported revenue: $13.9B in its fiscal year ended Dec 2025, about 1.8× MCO's $7.7B (fiscal year ended Dec 2025). MCO's net margin was 31.9% and STT's 21.1%. The SEC classifies them differently (Services-Consumer Credit Reporting, Collection Agencies; State Commercial Banks); what connects them is shared exposure to the Rates & central banks research theme, not a common industry.

MCO vs STT: audited financials
- Scale: STT's $13.9B of revenue is about 1.8× MCO's $7.7B.
- Net margin: MCO kept 31.9% of revenue as net income versus 21.1% at STT.
- Cash flow: operating cash flow is left out of this reading because lending, deposit, and trading balances run through it at banks, brokers, and insurers, so it does not measure earnings quality the way it does for an operating company.
- Periods: both fiscal years end on 2025-12-31, so these annual figures cover the same months.

Company-specific drivers maintained by Yield Theory. Use them to decide which filing deserves deeper work; they are not predictions.
What moves MCO
We have not yet published a company-specific driver list for MCO. The primary source is Item 1 (Business) and Item 1A (Risk Factors) of its 10-K filed 2026-02-18.

The investment question
You now know STT reports about 1.8× MCO's revenue, and MCO keeps more of each dollar as net income. Those are the facts. The investment question is what each share price already assumes about their exposure to rates & central banks, and which evidence in the next filings would prove that assumption wrong.

Read the full researchSEC filing comparison and disclosure evidence
Start with primary filings because fiscal calendars and accounting presentation can make superficially similar quarters incomparable. Both fiscal years end December 31, so annual reports line up, but check segment definitions before comparing growth or margins.
The current verified House and Senate snapshot contains 7 matched transaction rows for MCO and 10 matched transaction rows for STT. These delayed, range-based disclosures can identify a filing to inspect; they do not establish motive, conviction, or a real-time trading signal.

What this comparison cannot tell you
This page does not contain licensed live prices, a valuation model, earnings estimates, portfolio constraints, or a forecast of future returns. SEC classifications can be broad, company descriptions can lag strategic change, and the latest annual filing may predate a material acquisition or divestiture. Read subsequent quarterly and current reports before making a decision.
A stronger business is not automatically the better stock. Starting valuation, expectations, capital structure, cyclicality, dilution, and the probability of each thesis determine the investment outcome. Use this comparison to frame the work, then verify the numbers in the linked filings and current company disclosures.

MCO vs STT FAQs
Are MCO and STT direct competitors?
Not necessarily. Moody's files as Services-Consumer Credit Reporting, Collection Agencies and State Street as State Commercial Banks. The pair is compared because both map to the Rates & central banks research theme, not because the filings show head-to-head competition.
Is MCO or STT the bigger company by revenue?
State Street (STT) is the larger business by reported revenue: $13.9B in its fiscal year ended Dec 2025, about 1.8× MCO's $7.7B (fiscal year ended Dec 2025). MCO's net margin was 31.9% and STT's 21.1%. The SEC classifies them differently (Services-Consumer Credit Reporting, Collection Agencies; State Commercial Banks); what connects them is shared exposure to the Rates & central banks research theme, not a common industry. Each figure is the annual amount tagged in the company's own SEC XBRL filing; market value depends on live prices, which this page does not publish.
Which is better, MCO or STT?
There is no context-free winner. Compare the operating exposures, filing evidence, valuation, balance sheet, and risks against the specific thesis you are testing. This page deliberately does not turn a static profile into a buy or sell recommendation.
Does this MCO vs STT comparison include live prices?
No. Yield Theory does not republish unlicensed real-time market data. The financial figures on this page are the audited annual numbers Moody's Corporation and State Street Corporation tagged in their SEC XBRL filings. Use a regulated broker or licensed quote provider for current prices and valuation multiples.
Where does the company information come from?
Company classifications, fiscal year-ends, and filing links come from the SEC EDGAR submissions API snapshot refreshed 2026-11-09. Business summaries and research themes are maintained by Yield Theory.
