The difference between an investor who catches great opportunities and one who misses them often comes down to their screening process. Stock screeners let you filter thousands of companies down to the handful that match your exact criteria — before you commit hours of research time to something that fails a basic filter.
This guide covers the best stock screener stack for retail investors in 2026: free tools, paid tools, and how to use them together.
The Complete Screener Stack
| Tool | Best For | Price |
|---|---|---|
| Finviz | Quick fundamental + technical screens | Free / Elite $39.50/month |
| Koyfin | Deep financial data, charting, peer comparison | Free / Pro from $39/month |
| Trendspider | AI-powered technical analysis + backtesting | From $39/month |
| Simply Wall St | Visual fundamental analysis for individual stocks | Free / Premium $10/month |

1. Finviz — The Essential Free Screener
Finviz (Financial Visualizations) is the first tool most serious retail investors learn, and many never need to move beyond it for basic screening. It covers the most important fundamental and technical filters in one clean interface, and the free version is genuinely powerful.
Key Screening Filters
- Fundamental: P/E, P/S, P/B, EPS growth, revenue growth, ROE, debt/equity, dividend yield, payout ratio
- Technical: SMA position, RSI, price performance over multiple timeframes, pattern recognition
- Descriptive: Sector, industry, market cap, country, exchange, float, share count
Best Screens to Run on Finviz
- Quality Value: P/E under 15, ROE over 15%, debt/equity under 0.5, EPS growth positive last 5 years
- Growth at Reasonable Price (GARP): PEG under 1.5, EPS growth over 20% YoY, revenue growth over 15%
- 52-Week Lows with Strong Fundamentals: Price within 10% of 52-week low, P/B under 1.5, positive earnings
Free vs. Elite: The free version refreshes data with a 20-minute delay and lacks real-time alerts. Finviz Elite ($39.50/month) adds real-time data, alerts, backtesting, and correlation analysis. For most retail investors, the free version is sufficient to start.
2. Koyfin — The Research Platform
Once Finviz flags an interesting stock, Koyfin is where you go for depth. It’s a Bloomberg-lite research platform built specifically for individual investors — comprehensive financial data, charting, and peer comparison without the $25,000/year Bloomberg terminal price tag.
Key Features
- Financial dashboards: Income statement, balance sheet, cash flow, ratios — 10+ years of history with clean visualizations
- Peer comparison: Compare any company against its sector or custom peer groups across 50+ metrics
- Macro dashboards: Economic data, yield curves, factor returns — essential for understanding market context
- Watchlists with data tables: Build custom watchlists with any combination of metrics displayed
Best use case: Deep-dive research on the 5–10 companies that pass your Finviz screen. Before buying, run every candidate through a Koyfin financial dashboard + peer comparison.
3. Trendspider — For Technical Investors
If your investment process incorporates technical analysis — trend following, support/resistance, momentum — Trendspider automates much of the analysis that used to require hours of manual chart work. Its ML-powered trendline detection finds patterns across multiple timeframes simultaneously.
Key Features
- Automated multi-timeframe trendline detection
- Strategy tester — backtest any technical rule without coding
- Market scanner — screen for technical setups across thousands of tickers
- Smart alerts based on technical conditions
Best for: Investors who use technical analysis to time entries and exits on fundamentally screened stocks.
4. Simply Wall St — Visual Due Diligence
Simply Wall St translates complex financial data into visual “snowflake” diagrams that give you an instant read on a company’s valuation, financial health, growth trajectory, dividends, and management quality. It’s not a replacement for deep research, but it’s an excellent sanity-check tool.
Best Use Case
After running your Finviz screen, paste each ticker into Simply Wall St for a 30-second visual check. If the snowflake is severely distorted in an area you care about (e.g., weak financial health when you’re looking for quality), you can quickly deprioritize that company before spending more research time.
Price: Free tier available; Premium is $10/month — the best value tool in this stack for individual stock due diligence.
5. Wisesheets — For Data-Driven Investors
Wisesheets connects live financial data directly to Google Sheets or Excel. If you build custom models or comparison tables, Wisesheets lets those models update automatically with live data rather than requiring manual copy-paste every time you revisit them.
Best Use Cases
- Build a watchlist dashboard with 20+ companies and 30+ metrics that refreshes live
- Automate DCF models that pull current revenue/EPS/growth estimates automatically
- Historical data downloads for quantitative backtesting
The Complete Workflow
Here’s how to use the full stack efficiently:
- Screen (Finviz) — Run your quality/value/growth filters. Get your shortlist down to 20–30 tickers.
- Visual check (Simply Wall St) — Paste each ticker in. Eliminate obvious weak spots in 30 seconds per company. Cut list to 10–15.
- Deep research (Koyfin) — Full financial history, peer comparison, and ratio analysis on your shortlist. Cut to 5–8 serious candidates.
- Technical timing (Trendspider) — For companies you’re ready to buy, use Trendspider to identify optimal entry points based on technical levels.
- Track and model (Wisesheets) — Build a live watchlist in Sheets with all your positions and candidates so you always have a current view without manual updates.
Free-Only Stack (Zero Cost)
If you’re not ready to pay for tools yet, this all-free combination covers most of what you need:
- Finviz (free) — Primary screener
- Simply Wall St (free tier) — Visual due diligence
- Macroaxis (free) — Quantitative value screening and financial health scores
- SEC EDGAR (free) — Primary filings — 10-K, 10-Q, proxy statements
You can generate serious investment ideas without paying a dollar. The paid tools add speed and depth, not a fundamentally different process.
Bottom Line
The right screener stack doesn’t find you great stocks — it eliminates bad ones efficiently, so you spend your limited research time where the real opportunity is. Finviz + Koyfin is the core combination that serious retail investors come back to. Add Trendspider if technical timing matters to you, and Wisesheets if you want a data-driven spreadsheet workflow.
