- The primary source for public-company data is SEC EDGAR, and it's free.
- Free screeners and charts cover the scanning; FRED and Investor.gov cover the context.
- Check FINRA BrokerCheck before anyone suggests an investment to you.
Real investment research doesn't need a paid terminal. The underlying data is public and free; filings, financials, market history, and broker records. These ten sites put an analyst's toolkit in reach of an empty wallet.
Everything else is commentary. The 10-K, 10-Q, and proxy statements on SEC EDGAR are primary sources; no newsletter writing them in, no headline spinning them.
| Site | What it gives you | Who it's for |
|---|---|---|
| SEC EDGAR | Every official filing, free | Anyone researching a company |
| FINRA BrokerCheck | Broker licenses and complaint histories | Before trusting any advisor |
| Morningstar | Ratings and fund data | Fund and ETF research |
| Koyfin | Pro-grade charts, free tier | Chart-minded investors |
| Finviz | Free stock screeners | Finding candidates by criteria |
| TradingView | Charting and community | Technical analysis |
| Yahoo Finance | Financials, news, key stats | The everyday overview |
| St. Louis Fed FRED | Macro and rate data | The big picture |
| Investor.gov | Official explainers and calculators | Learning the rules first |
| SEC enforcement + state sites | Fraud records and actions | Skeptics with a question |
A five-step free research loop
- Screen with Finviz or a simple filter for companies you can explain.
- Read the 10-K: revenue, margins, debt, and the risks section.
- Check the market: valuation and price history on Yahoo or TradingView.
- Get context: rates and inflation from FRED.
- Write two sentences on why you'd own it. If you can't, you're not ready.
Places to double-check the numbers
- Fund and ETF fees → Morningstar's free pages and the fund's own prospectus.
- Retirement rules → Investor.gov's official calculators.
- Company court cases and actions → SEC enforcement and your state regulator.
If you're growing a retirement account, the research that matters is your time in the market and your fees; not picking the next stock. These tools shine once your basics are funded.

FAQ
Frequently asked questions
Is free investment research as good as paid?
For most individual investors, yes. Filings, financials, and market data are public and free; paid services mostly repackage them with convenience and commentary. Start free, and you'll discover which conveniences are actually worth paying for.
What's the first thing to check on any stock?
The company's latest 10-K and 10-Q on SEC EDGAR, and whether the person recommending it is registered; that's FINRA BrokerCheck. Filings tell you what's true; registration tells you who's accountable.
