Best stock screeners in 2026
A screener is only as good as the filters you can compose and the shortlist it hands back. Here’s what separates a genuinely useful screener from a phone book, an honest look at the popular options, and where Tradune fits.
The short answer
- Finviz
- if you want the fastest free screener and market heat-map, and nothing else.
- Stock Rover
- if you screen on deep fundamentals and historical financials on a desktop.
- Koyfin
- if you want screening inside a broad market-data and macro dashboard.
- Tradune
- if you want a multi-factor screener that sits on top of your own portfolio, risk analytics and insider signals — free right now.
Not a ranking and not an award — each line is the need that tool is the right answer for, checked against its own public plans as of October 2026.
How to choose a stock screener
Multi-factor filtering
One filter (like “low P/E”) finds value traps. Real screening layers valuation, growth, quality and technicals so factors check each other.
A readable shortlist
The job is 10–30 names worth researching, not 400 or 3. Good screeners are tuned to produce a workable list.
Saveable, re-runnable screens
Your thesis is reusable — you should be able to save a screen and re-run it next week in one click.
Fair price for the depth
Deep screening shouldn’t need a separate subscription on top of the tools you use for tracking and risk.
The options, honestly
No fabricated ratings — just what each tool is good at, so you can match one to your needs.
| Tool | Price | Strongest at | Where it stops |
|---|---|---|---|
| Tradune | Free right now | Multi-factor screening wired straight to your own portfolio, risk analytics and signals | Fewer raw fundamental fields than Stock Rover, and the deep multi-factor screener is earmarked for Pro once paid plans exist |
| Finviz | Free / $39.50/mo (Elite) | Extremely fast, familiar screener and market heat-map | No risk (VaR) or tax-loss-harvesting analytics |
| Stock Rover | Free / $29+/mo | Very deep fundamental database and historical financials | No dedicated cluster-buy or Form 4 signal workflow (insider and institutional data appear as panels) |
| Koyfin | Free / $39–$79/mo | Broad market, analyst-estimate and macro data coverage | Portfolio risk metrics are drawdown and exposure based; no VaR workflow found |
Tradune’s screener is multi-factor across valuation, growth, quality and technicals, with saveable screens — and it sits next to a portfolio tracker, risk analytics and signals in one free-right-now workspace, so screening isn’t a separate subscription.
