Which should you use: StockEyes or Finviz?
Use Finviz if your main job is screening: narrowing thousands of stocks to a watchlist with fundamental, technical, and descriptive filters, on a free tier that asks for nothing. Its screener is one of the fastest and most generous free tools in investing, and the market maps give an instant read on sector leadership. Use StockEyes if your main job is following institutional money: 13F ownership research, quarter-over-quarter changes in what professional managers hold, cluster buying across managers, and insider Form 4 activity. StockEyes is not a general-purpose screener and does not try to be; it is a filing-based ownership research site, and its free institutional-ownership pages go deeper on 13F data than Finviz's ownership columns do.
The honest summary: Finviz answers "which stocks match these criteria." StockEyes answers "who owns this stock, who is buying or selling, and what changed last quarter." Many investors use both, screening on Finviz and researching the survivors' ownership on StockEyes. The rest of this page explains exactly where each product's strengths and limits are, so the choice is a fit decision, not a loyalty decision.
What each product actually is
Finviz, short for financial visualizations, is a stock screening website that has offered a free screener for nearly two decades. Its core product is a filter system: combine descriptive filters (sector, industry, country, market capitalization) with fundamental filters (P/E, earnings growth, dividend yield, margins) and technical filters (price relative to moving averages, RSI, pattern recognition), and get a sortable table of matching stocks. Around that core sit the signature market maps, treemap visualizations that show sector and market performance at a glance, plus stock pages with charts, news, insider summaries, and statistics. The free tier works without registration; the paid tier, Finviz Elite, adds real-time data, premarket and after-hours quotes, alerts, exports, and advanced charting.
StockEyes is an institutional-ownership and insider-research site. Its core product is filing-based ownership research: per-ticker pages showing which professional money managers hold a stock, how their positions changed quarter over quarter from 13F filings, and tools built on that data, including a 13F change screener and a cluster-buying screener that surfaces managers increasing positions across several tickers. StockEyes also publishes a Form 4 insider-trading lesson, a market events calendar, a verified market-news hub, and a stock-market glossary. The institutional-ownership pages are free; the 13F screeners are signed-in Pro tools. StockEyes has no general fundamental or technical screener, no charting platform, and no real-time quote product.
Put side by side, the two products overlap in exactly one place: both show some ownership and insider information. Everywhere else they do different jobs. Finviz is built for breadth and speed across the whole market. StockEyes is built for depth on one question: what are institutions and insiders doing. Understanding that difference makes the rest of the comparison straightforward.
Screening filters compared
Screening is Finviz's home turf, and the comparison is not close on this dimension. Finviz's screener offers dozens of filters across descriptive, fundamental, technical, and pattern categories. You can screen for value (low P/E, low PEG, high dividend yield), growth (EPS growth, sales growth), quality (ROE, margins), technical setups (price above the 50-day average, RSI oversold, new highs), and ownership (insider ownership, institutional ownership, short float). Results can be viewed as overview, valuation, financial, ownership, performance, or technical tables, and the same filtered list follows you across views. The free tier includes the full standard filter set, which is why Finviz remains a common first stop for investors learning how screening works.
StockEyes does not compete on general screening. Its screeners are 13F-based: the 13F change screener filters by changes in institutional holders, changes in shares held, holder counts, and position values across quarters, and the cluster-buying screener finds managers increasing reported positions across several tickers. These answer ownership questions that Finviz's ownership view cannot, such as "which managers added the most shares last quarter" or "which stocks saw the largest quarter-over-quarter increase in institutional holders." But if you want to screen for P/E below 15 and revenue growth above 20 percent, StockEyes is not the tool; Finviz is.
| Capability | Finviz | StockEyes |
|---|---|---|
| Fundamental filters (P/E, growth, margins) | Dozens, free tier | Not offered as a general screener |
| Technical filters (RSI, moving averages, patterns) | Dozens, free tier | Not offered |
| Descriptive filters (sector, market cap, country) | Yes, free tier | Not offered as a general screener |
| Ownership filters (insider/institutional stakes) | Basic columns and filters | 13F change and cluster-buying screeners (Pro) |
| Saved screens and presets | Yes, with account; Elite expands limits | Ownership screens built around filing quarters |
| Market visualization | Signature treemap market maps | Not offered |
Reading the table: Finviz wins the general-screening row in every category. StockEyes wins only the ownership-depth row, and it wins it by doing something Finviz does not attempt: quarter-over-quarter 13F change research at the manager level.
Data depth: 13F filings, insider trades, and short interest
This is the dimension where StockEyes leads, and it is worth explaining why the depth matters. Finviz shows institutional and insider ownership as summary data: percentage of shares held by institutions, insider ownership percentage, and a table of recent insider transactions on stock pages. That is genuinely useful for a quick check, and it is free. But it is a snapshot, not a research product: it does not show which managers hold the stock, how each manager's position changed last quarter, or the multi-quarter history of institutional accumulation and distribution.
StockEyes treats 13F filings as a primary research dataset rather than a sidebar statistic. Institutional investment managers with over $100 million in qualifying assets file Form 13F quarterly, disclosing long positions in U.S.-listed equities within 45 days of quarter end. StockEyes' free institutional-ownership pages organize that filing data per ticker: which managers hold the stock, position sizes, and how holdings changed. The Pro screeners go further, filtering the whole dataset by holder-count changes, share-count changes, and position values, and the cluster-buying view surfaces managers adding to positions across multiple tickers at once. A manager directory and comparison tools round out the ownership research workflow.
On insider trading, both products aggregate Form 4 filings, but with different emphasis. Finviz shows recent insider transactions on stock pages as part of a broad data dashboard. StockEyes pairs insider data with an evidence-first lesson on reading Form 4 that teaches the transaction codes, 10b5-1 plan disclosures, and cluster-buy logic needed to separate signal from compensation noise. The philosophy is filing-first: the aggregated table is the starting point, and the original filing is the verification step.
On short interest, Finviz includes short float as a screener filter and on stock pages, which StockEyes does not match with a dedicated short-interest product. If short-squeeze screening is central to your process, Finviz's short-float filter is the practical choice. StockEyes' short-interest coverage is limited to what appears in its educational material.
| Dataset | Finviz | StockEyes |
|---|---|---|
| 13F institutional ownership | Summary percentages and ownership-view columns | Manager-level holdings, quarterly changes, free per-ticker pages |
| 13F change screening | Not offered | Dedicated 13F change screener (Pro) |
| Cluster buying across managers | Not offered | Dedicated cluster-buying screener (Pro) |
| Insider transactions (Form 4) | Recent-transaction tables on stock pages | Aggregated data plus a full Form 4 reading lesson |
| Short interest / short float | Screener filter and stock-page data | Educational coverage only |
| Analyst ratings and estimates | Shown on stock pages | Not a focus |
One caveat applies to all 13F research on any platform: filings arrive up to 45 days after quarter end, so the data is always somewhat stale, and 13F covers only long positions in U.S.-listed equities, not shorts, bonds, or international holdings. StockEyes' 13F screening guide explains these limits in detail. Depth does not remove the lag; it just makes the lagged data more useful.
Data speed, alerts, and exports
Data speed is the clearest reason anyone pays for Finviz Elite. The free tier runs on delayed quotes, which is fine for end-of-day research and learning but not for anything happening intraday. Elite upgrades to real-time quotes plus premarket data from 4:00 AM ET and after-hours data to 8:00 PM ET, which is the single biggest reason day traders subscribe. Elite also adds unlimited email and push alerts on price moves, news, insider trades, and SEC filings, Excel and CSV export, API access, and up to eight years of financial-statement history. The free tier has no alerts and no export.
StockEyes operates on a different clock because its core data is quarterly. 13F filings arrive in waves after each quarter end; Form 4 insider filings arrive within two business days of the transaction. There is no real-time quote product, no premarket data, and no intraday alert engine, because the research questions StockEyes answers (who is accumulating, what changed last quarter) do not require intraday speed. The market-news hub is refreshed on a regular cycle with source-linked stories, and the events calendar tracks confirmed market dates, but neither is a substitute for a real-time terminal.
The practical takeaway: if your workflow needs real-time prices, premarket scans, or price alerts, StockEyes cannot do that job at any tier, and Finviz Elite is one of the more affordable ways to get it. If your workflow is quarterly ownership research, Finviz's real-time feed adds nothing, because the underlying filings update on a 45-day lag regardless of how fast your quotes are.
Pricing compared
Finviz's pricing is public and simple. The free tier costs nothing, requires no account, and includes the full standard screener, market maps, stock pages with insider summaries, and delayed data. Finviz Elite is listed at $39.50 per month or $299.50 per year, which works out to about $24.96 per month on annual billing, and adds real-time data, premarket and after-hours quotes, advanced filters, unlimited alerts, Excel and CSV export, API access, and an ad-free experience. A free trial is available. As with any subscription, check the current pricing page before subscribing, since plans and prices change.
StockEyes keeps its institutional-ownership pages, market news, events calendar, glossary, and learn lessons free. The 13F change screener, cluster-buying screener, manager directory detail, and comparison tools are signed-in Pro tools. StockEyes publishes no general-screener paid tier because it has no general screener; the paid layer exists only around the institutional-ownership dataset.
| Tier | Finviz | StockEyes |
|---|---|---|
| Free | Full standard screener, maps, stock pages, delayed data, no account needed | Institutional-ownership pages, market news, events, glossary, learn lessons |
| Paid | Elite: about $39.50/mo or $299.50/yr; real-time data, alerts, exports, no ads | Pro: 13F change and cluster-buying screeners, manager detail, comparisons |
| Trial | Free Elite trial offered | Free ownership pages need no trial |

Where each one honestly wins
Dozens of fundamental, technical, and descriptive filters on a free tier, with sortable multi-view results and the fastest screening workflow in the free-tool category. Nothing StockEyes offers replaces this.
The treemap market maps remain the quickest way to see which sectors and industries are leading or lagging on any given day. It is a genuinely distinctive feature, not a gimmick.
Elite's real-time quotes, premarket and after-hours data, and unlimited alerts serve intraday and active traders. StockEyes has no equivalent product.
Manager-level holdings, quarterly change tracking, a dedicated 13F change screener, and cluster-buying detection. Finviz shows ownership as a summary statistic; StockEyes treats it as a research dataset.
A full Form 4 lesson covering transaction codes, 10b5-1 plans, and cluster logic, paired with the data. Finviz shows the transactions; StockEyes teaches the reading.
Every ownership claim traces to a filing, with an events calendar and source-linked news. The site is built for investors who verify before they act.
Who each tool is best for
Choose Finviz if you screen for ideas
You run screens regularly: value filters on weekends, momentum scans during earnings season, oversold bounces when markets fall. You want the fastest path from "the whole market" to "twenty names worth researching," and you want it free or close to free. You may also want premarket data and alerts if you trade actively, in which case Elite's pricing is modest compared with most trading platforms.
Choose StockEyes if you research ownership
Your questions start with "who": who owns this stock, which managers bought last quarter, are insiders buying alongside institutions, is ownership concentrating or dispersing. You read 13F filings, or you want to without learning EDGAR's interface. You care about the evidence trail from filing to conclusion, and you are comfortable with quarterly data that lags by design.
Choose Finviz if you are learning
New investors learning how screening works get the most from Finviz's free tier: no account, no paywall on the core filters, and enough depth to learn what P/E, ROE, and RSI filters actually do. Pair it with StockEyes' learn lessons for the concepts behind the filters.
Neither is a charting platform or a broker
Worth stating plainly: neither product executes trades, and neither replaces a charting platform for technical analysis. Finviz's charts are basic even on Elite; StockEyes has no charts product at all. Budget separately for charting if your process needs it.
Using both together: a practical workflow
The two products complement each other cleanly because they answer different questions at different stages. A practical two-tool workflow looks like this:
- Screen on Finviz. Run your fundamental or technical screen, for example, profitable companies with P/E below the market average and rising revenue, and export or save the resulting watchlist.
- Check ownership on StockEyes. For each survivor, open the free institutional-ownership page: who holds it, whether holder counts are rising or falling, and whether any manager made it a new or enlarged position last quarter.
- Read the insider evidence. Check recent Form 4 activity with the insider lesson's checklist: open-market purchases by multiple insiders carry weight; option exercises and 10b5-1 plan sales usually do not.
- Verify the business. A screen match with strong ownership is a research lead, not a conclusion. Read the 10-K, check the events calendar for upcoming catalysts, and write down what would change your mind before acting.
- Set alerts where they exist. Finviz Elite alerts can watch your shortlist for price, news, and filing triggers. StockEyes' quarterly cadence means ownership checks happen on a calendar, not a ticker.
This workflow uses each product for what it is actually good at: Finviz for breadth and speed, StockEyes for ownership depth and filing evidence. Neither product needs to win for the combination to work.
Questions about StockEyes vs Finviz
Is Finviz really free?
Yes, the core screener, market maps, stock pages, and insider summaries are free without an account, on delayed data. Finviz Elite, the paid tier, adds real-time data, premarket and after-hours quotes, alerts, exports, and advanced charting for a monthly or annual fee.
Does Finviz show institutional ownership?
Yes, as summary data: institutional ownership percentages, ownership-view screener columns, and related statistics on stock pages. What it does not offer is manager-level 13F research, quarterly change tracking per manager, or a dedicated 13F change screener, which is StockEyes’ specialty.
Can StockEyes replace Finviz’s screener?
No, and it does not try to. StockEyes has no general fundamental or technical stock screener. Its screeners are 13F-based: filtering by changes in institutional holders, shares, and position values across quarters, plus cluster-buying detection across managers.
Which is better for beginners?
Finviz, for learning how screening works: the free tier needs no account and covers the standard fundamental and technical filters. StockEyes’ learn lessons complement it with the concepts behind the filters, and its free institutional-ownership pages add an ownership dimension most beginners never see.
How much does Finviz Elite cost?
Finviz lists Elite at $39.50 per month or $299.50 per year, about $24.96 per month on annual billing, as of October 2026. A free trial is offered. Prices change, so check Finviz’s current pricing page before subscribing.
What is StockEyes Pro?
StockEyes Pro is the signed-in tier that unlocks the 13F change screener, the cluster-buying screener, manager directory detail, and comparison tools. The per-ticker institutional-ownership pages, market news, events calendar, glossary, and learn lessons remain free.
Do I need real-time data to research 13F filings?
No. 13F filings arrive up to 45 days after quarter end by regulation, so the ownership dataset updates on a quarterly cadence regardless of quote speed. Real-time data matters for trading and screening workflows, not for filing-based ownership research.
Can I use both Finviz and StockEyes?
Yes, and that is the recommended setup in this guide: screen for ideas on Finviz, then research each survivor’s institutional ownership and insider activity on StockEyes before reading the underlying business filings.
