Essential Tools
The five tools every investor should bookmark right now.
Finviz
Screener & VisualizationThe most powerful free stock screener on the internet. Heat maps, technical charts, insider trading, and fundamental screening all in one place.
Best for: Finding stocks that match specific fundamental or technical criteria. The heat map alone is worth bookmarking.
Finviz Elite is worth the money if you trade actively, but the free tier is better than most paid screeners. The heat map view of the S&P 500 is the fastest way to understand what's happening in the market on any given day. I use it almost daily.
SEC EDGAR
Regulatory FilingsEvery public company filing — 10-Ks, 10-Qs, proxy statements, insider transactions — directly from the source. No middleman, no spin.
Best for: Reading actual financial statements instead of someone else's summary. The full-text search is underrated.
EDGAR's interface looks like it was designed in 1997 because it was. But the data is the gold standard. If you're making an investment decision based on a blog post instead of reading the actual 10-K, you're doing it wrong. I spent years reading GSE filings here. The EDGAR full-text search is a secret weapon most retail investors don't know about.
Macrotrends
Historical Financials10+ years of revenue, earnings, margins, and ratios for every public company — beautifully charted and instantly accessible.
Best for: Understanding long-term financial trends. The interactive charts showing 10-year revenue growth or margin expansion are incredibly useful.
Macrotrends is the tool I recommend most to new investors. Want to know if a company's margins are expanding or contracting over the last decade? Macrotrends shows you in 3 clicks. The ad load is annoying, but the data is excellent and completely free. The macro economic charts (GDP, inflation, unemployment over decades) are a goldmine for perspective.
Yahoo Finance
All-in-OneThe Swiss Army knife of financial data. Quotes, financials, analyst estimates, news, portfolio tracking — all free.
Best for: Quick lookups, earnings dates, analyst estimates, and keeping a watchlist. The conversation boards are terrible but addictive.
Yahoo Finance has gotten worse over the years as they've tried to push Premium, but the free tier is still the best all-in-one financial data source on the web. The financials tab, the analyst estimates, and the earnings calendar are all I need for initial research. The message boards are a dumpster fire and I love them.
FRED (Federal Reserve Economic Data)
Economic Data816,000+ economic time series from 108 sources. GDP, inflation, employment, interest rates, money supply — if it's a macroeconomic data point, FRED has it.
Best for: Macroeconomic research and understanding the big picture. Creating custom charts that overlay different economic indicators.
FRED is the most underrated free tool in finance. Every professional economist uses it, but most retail investors have never heard of it. Want to chart the yield curve over 30 years? FRED. Want to see the correlation between M2 money supply and inflation? FRED. Want to settle an argument about whether unemployment leads or lags recessions? FRED. It's the single best source of economic data in the world and it's completely free.

Great Tools
Specialized tools that fill important gaps in your research workflow.
Wisesheets
Spreadsheet Add-onPull real-time and historical financial data directly into Google Sheets or Excel. Like having a Bloomberg terminal in a spreadsheet.
Best for: Building custom financial models, screening stocks by your own criteria, and backtesting strategies in a spreadsheet.
If you're the kind of person who builds spreadsheets for fun (no judgment, I'm one of you), Wisesheets is game-changing. The free tier is limited but the concept is perfect: financial data belongs in spreadsheets, not locked behind proprietary platforms. Pull 10 years of financials for 50 companies and do your own analysis. That's real investing.
Koyfin
Research PlatformA Bloomberg-lite terminal for retail investors. Dashboards, screening, charting, and financial analysis — the free tier is shockingly good.
Best for: Investors who want institutional-quality dashboards without paying institutional prices. The comparative analysis features are excellent.
Koyfin is what happens when someone looks at a Bloomberg terminal and says 'I can build this for free.' The free tier gives you access to data and visualization tools that would cost $20K/year on Bloomberg. The sector performance dashboards and the ability to compare financials across companies side-by-side are genuinely best-in-class. The catch: the free tier has limitations on data history and the number of charts you can save.
TipRanks
Analyst RatingsTrack analyst performance, see who's actually good at stock picks, and check the consensus rating for any stock.
Best for: Filtering out the noise from Wall Street. TipRanks tracks which analysts actually make money and which ones are just generating commissions.
The genius of TipRanks is simple: they track whether analysts' picks actually make money. Turns out, most don't. The platform lets you filter by analyst track record, which is the single most useful thing anyone has done with Wall Street data. The free tier is limited but the analyst ranking concept alone is worth knowing about.
Simply Wall St
Visual AnalysisSnowflake charts that score stocks on value, future growth, past performance, health, and dividends. Beautiful visual analysis.
Best for: Visual learners who want a quick health check on a stock without reading through financial statements.
The snowflake chart is one of the best visual innovations in retail investing. At a glance, you can see if a stock is cheap, growing, profitable, and financially healthy. The free tier limits you to a handful of stocks per month, which is annoying but understandable. Use it as a starting point for research, not as your entire thesis.
OpenInsider
Insider TradingReal-time SEC Form 4 filings showing when company insiders buy and sell their own stock.
Best for: Tracking whether company executives are buying or selling. Insider buying is one of the most reliable bullish signals.
There's a famous investing saying: 'Insiders sell for many reasons, but they only buy for one.' OpenInsider makes it trivial to track cluster buying (multiple insiders buying at the same time), which is one of the strongest bullish signals in the market. The interface is bare-bones but the data is pure. I check this weekly.
Useful Tools
Niche but valuable for specific research needs.
Barchart
Technical & Options DataFree options data, unusual activity tracking, and technical screening. The options side is particularly strong.
Best for: Options traders who want to see unusual activity, open interest changes, and implied volatility without paying for expensive platforms.
Barchart's free options data is better than what many paid platforms offer. The unusual options activity screener has caught some genuinely interesting trades before they moved. The technical opinion feature (aggregating multiple indicators into a single opinion) is useful for confirmation, though obviously not a crystal ball.
Gurufocus
Value InvestingTrack what legendary investors are buying and selling via their 13F filings. Plus a solid DCF calculator and value screener.
Best for: Value investors who want to see what Buffett, Munger, Ackman, and other gurus are buying before the market catches on.
The guru portfolio tracking is the killer feature. Yes, 13F filings are delayed by 45 days, but seeing that Berkshire just initiated a position still tells you something. The DCF calculator is decent for quick valuations, and the financial strength rankings (based on Piotroski and Altman Z-scores) add genuine analytical value.
Stratosphere.io
Fundamental AnalysisKPI tracking for growth companies. Revenue segments, user metrics, and business-specific data that most platforms don't bother to track.
Best for: Investors researching tech and growth companies who need to understand the actual business drivers, not just the P/E ratio.
Most financial data platforms give you the same 30 ratios for every company. Stratosphere actually tracks company-specific KPIs — like AWS revenue for Amazon, or daily active users for Meta. That's the data that actually matters for understanding whether a business is getting better or worse. The free tier is limited but the concept is ahead of its time.
Stock Analysis
Financial DataClean, fast, ad-light financial data. Financials, screener, IPO calendar, and earnings data with a modern interface.
Best for: People who want Yahoo Finance's data without Yahoo Finance's ad-bloated interface. The IPO and earnings calendars are particularly clean.
Stock Analysis is what Yahoo Finance should have become. It's fast, clean, and doesn't assault you with pop-ups. The financial statements are easy to read, the screener works well, and the IPO calendar is one of the best free ones available. It won't give you deep analytical tools, but for basic financial data lookup, it's my preferred alternative to Yahoo Finance.
Dataroma
Superinvestor TrackingTrack the portfolios of the world's best investors — Buffett, Pabrai, Greenblatt, Klarman — via their SEC filings.
Best for: Idea generation. Seeing what smart money is buying and selling, with portfolio-level context.
Dataroma is ugly, simple, and incredibly useful. It aggregates 13F filings from about 70 superinvestors and shows you their current holdings, recent buys, and recent sells. The 'Common Stock Holdings' view — showing which stocks appear in multiple guru portfolios — is the fastest way to generate investment ideas from the smartest people in the room. The site looks like it was made in 2005 and I hope it never changes.

Frequently Asked Questions
What is the best free stock screener?
Finviz is the best free stock screener for most investors. It lets you filter by over 60 fundamental and technical criteria, shows heat maps of market sectors, and includes insider trading data. For a more visual approach, Koyfin offers institutional-quality screening with a modern interface. Both have free tiers that outperform many paid alternatives.
Can I do real stock analysis without paying for tools?
Absolutely. SEC EDGAR gives you the actual financial filings for free. Macrotrends charts 10+ years of financial data. FRED provides every macroeconomic data point you could want. Finviz screens and visualizes the entire market. Combined, these free tools give you 90% of what a Bloomberg terminal does for fundamental analysis. The main things you'd miss are real-time data feeds and institutional-grade options analytics.
What's the best free alternative to Bloomberg Terminal?
Koyfin is the closest free alternative to Bloomberg for retail investors. It offers dashboards, financial data, comparative analysis, and screening tools that mimic Bloomberg's layout. For economic data specifically, FRED (from the Federal Reserve) is actually better than Bloomberg for historical macro data. No free tool replicates Bloomberg's real-time data feeds or chat function, but for research and analysis, you can get surprisingly close for $0.
How do I track what Warren Buffett is buying?
Dataroma and Gurufocus both track 13F filings, which large investment managers must file quarterly with the SEC. These filings are delayed by 45 days, so you won't see real-time moves, but you can track portfolio changes over time. OpenInsider tracks individual insider buys and sells in real-time via SEC Form 4 filings. For Berkshire Hathaway specifically, the quarterly 13F is the best source.
Are free stock analysis tools accurate?
The free tools on this list pull from the same data sources as paid platforms — SEC filings, exchange data feeds, and government databases. The data itself is accurate. Where free tools fall short is in real-time speed (most have 15-minute delays), historical depth (some limit how far back you can go), and advanced analytics (DCF models, Monte Carlo simulations). For fundamental research and stock screening, free tools are more than sufficient.
