Stock Analysis (stockanalysis.com) is a clean, fast financial data platform that has grown rapidly by offering free access to financial statements, analyst estimates, and IPO calendars. SafetyMargin.io serves a more focused niche — providing Buffett-style analytical tools that go beyond displaying data to helping you interpret it.

Where SafetyMargin.io Stands Out
Analytical Depth Beyond Data Display
Stock Analysis excels at presenting financial data clearly — income statements, balance sheets, cash flow statements, all neatly formatted. But displaying data is not the same as analyzing it.
SafetyMargin.io takes the next step. The three-scenario DCF helps you model different outcomes and quantify your margin of safety. The Reverse DCF answers the critical question: what growth rate is the market already pricing in? The Buffett Signal cross-references valuation with sentiment to generate a disciplined action signal.
Forensic Accounting
Stock Analysis does not assess the quality or reliability of financial statements. SafetyMargin.io runs three automated forensic tests:
- Beneish M-Score — flags potential earnings manipulation using 8 financial ratios
- Altman Z-Score — quantifies bankruptcy risk with a 5-factor model
- Sloan Ratio — reveals whether reported earnings are supported by actual cash flow
These tests add a critical layer of due diligence that pure data platforms miss.
Capital Allocation Framework
SafetyMargin.io evaluates management quality through a suite of metrics that Stock Analysis does not offer: Owner Earnings (Buffett's preferred cash flow), ROIIC (return on incremental invested capital), SBC-Adjusted FCF (true dilution-adjusted cash generation), the $1 Retained Earnings Test, and Buyback Effectiveness scoring.
Investment Workflow
The built-in Buffett Checklist and Notes Panel let you document your research, track your thesis, and record evidence for each stock — all saved locally and instantly available when you return. Stock Analysis does not offer qualitative research tools.
Where Stock Analysis Stands Out
Financial Statement Tables
Stock Analysis presents full financial statements (income statement, balance sheet, cash flow) in clean, sortable tables with quarterly and annual views. For investors who want to read the raw numbers, this is excellent.
IPO and Earnings Calendars
Stock Analysis maintains a popular IPO calendar and earnings calendar. These are useful tools for event-driven investors that SafetyMargin.io does not offer.
ETF Coverage
Stock Analysis provides detailed ETF data including holdings, expense ratios, and comparisons. SafetyMargin.io focuses exclusively on individual stock analysis.
Data Breadth
Stock Analysis covers a broader universe of US-listed securities with financial statements going back further than SafetyMargin.io's 4-year window.
Pricing
| SafetyMargin.io | Stock Analysis | |
|---|---|---|
| Free tier | Full access to all features | Generous free tier |
| Premium | N/A (everything is free) | $9.99/month |
Stock Analysis Pro adds advanced screeners, unlimited comparisons, and Excel exports.
