Don't trust it — verify it
Every number links back to the exact passage in the filing it came from, so you (or your agent) can check any figure against the primary source. Multi-source — SEC filings, earnings transcripts, IR disclosures, and a market-data feed — with every limitation stated.
Why Accuracy Matters
You're comparing two platforms. Platform X shows a company with 50% profit margin. Platform Y shows 20%. Which is right?
Bad data leads to bad decisions — and an AI agent built on bad data automates them at scale. So we don't ask you to take our word for it: every figure on MetricDuck links back to the exact passage it came from. Fundamentals parse straight from SEC EDGAR filings; signals also draw on earnings transcripts and IR disclosures; prices come from a market-data feed — and every number is one click from its source, so you can check it yourself.
Click-to-source: every fundamental links to the exact line in the official SEC filing — the same primary source regulators and institutional investors use. Don't trust it; verify it.
How We Ensure Accuracy
Think of it like reading a student's report card directly from the school versus getting it third-hand through multiple people. We go straight to the source.
1. Primary-source by default
Fundamentals come straight from SEC EDGAR, the official repository for US public-company disclosures — no aggregation middlemen. Qualitative signals add earnings transcripts and IR disclosures; prices come from a market-data feed. Whatever the source, the number stays linked to it.
2. Automated Quality Checks
Every filing goes through validation: balance sheet equations, revenue trend analysis, and range checks. Data that fails validation is flagged for review.
Transparency in Action
Direct SEC Sourcing
Apple's revenue? Pulled directly from their 10-K filing on SEC Edgar. No aggregation errors, no third-party databases—just official SEC data.
Standard Calculations
Most metrics require just 1-2 arithmetic operations from standard GAAP line items. Complex metrics (ROIC, WACC) use industry-standard formulas.
No Gap Filling
Missing data appears as "N/A" with an explanation. We never estimate, interpolate, or fill gaps with industry averages.
Last Updated Timestamps
Every page shows when data was last refreshed, so you know exactly how current the information is.
Watch It Yourself
Don't take our word for it. The inspector replays a real agent run against MetricDuck — every tool call, every returned fact, every citation back to the source filing, visible.
Limitations
Trust requires stating what we don't do as plainly as what we do:
Fundamental Data, Not Trading Signals
We provide SEC-based fundamental analysis, not real-time trading data or technical indicators. Prices are end-of-day only. New filings are typically processed within minutes of appearing on SEC EDGAR.
GAAP-Focused
We show Generally Accepted Accounting Principles (GAAP) metrics. Company-specific non-GAAP adjustments require manual review of footnotes.
US Public Companies
Currently covers US public companies with SEC filings. Complex structures (REITs, banks, holding companies) may require additional manual analysis.
Found an Error?

Include: Company name, specific metric, what you expected vs. what you see
Response time: We investigate within 24 hours and make corrections as quickly as possible.
Technical Methodology
For technical users, developers, and search engines
Data Collection Process
We monitor SEC Edgar continuously for new 10-K, 10-Q, and 8-K filings. XBRL (eXtensible Business Reporting Language) data is parsed using industry-standard parsers. Each data point is tagged with original XBRL tag (e.g., us-gaap:Revenues), filing date, period covered, and reference to source filing.
Challenge: Companies use 50+ different XBRL tags for the same concept (revenue). Our system handles common variations but may miss unusual custom tags.
Validation & Quality Checks
Before publishing, automated checks verify: balance sheet equations (Assets = Liabilities + Equity), revenue trend analysis (flag unusual changes >50% QoQ), metric range validation (ROIC between -100% and 1000%), and missing data detection.
Calculated Metrics
We compute 323+ derived metrics including ROIC (Return on Invested Capital), WACC (Weighted Average Cost of Capital), FCF (Free Cash Flow), and financial ratios. Most metrics require just 1-2 arithmetic operations from GAAP line items. Complex metrics use industry-standard formulas.
Edge case handling: Negative equity for ROIC and zero share count scenarios are handled conservatively (shown as N/A when calculations would be misleading).
Update Frequency & Timeliness
Financial statements: New 10-K/10-Q filings are typically processed within minutes of appearing on SEC EDGAR.Calculated metrics: Recomputed automatically when new financials are published.Company metadata: Industry, sector, and descriptions refreshed weekly.
Historical Data Coverage
7-10 years of historical data available depending on company age and XBRL adoption timeline. Pre-2009 filings may not be available in structured XBRL format.
