Insider and hedge fund activity can reveal where experienced investors see opportunity before the broader market catches on. Watching these moves will not guarantee returns, but it can surface ideas worth researching further.
Company insiders, including CEOs, CFOs, and board members, have the closest view of a business. When they buy shares with their own money, particularly after a stock has pulled back, it often reflects confidence in the underlying fundamentals. Insiders rarely put personal capital at risk unless they believe the outlook is stronger than the current price suggests.
Hedge fund managers bring a different lens. With dedicated research teams, deep industry relationships, and significant capital to deploy, they tend to act with conviction. Studying their 13F filings can highlight where professional investors are building positions and how those positions change over time.
For individual investors, tracking this activity is not a shortcut. It is a starting point. The real work comes from understanding why insiders or funds are buying and whether the thesis holds up under closer examination.
Below are the best free tools to track insider and hedge fund buying, along with what each platform does well and where it falls short.
The Best Platforms You Should Be Using Today

TIKR makes it easy to evaluate insider buying for any stock by showing the exact trade date, amount, and role of the insider. It’s the best choice if you want insider data alongside full stock research.

What to Look for in an Insider Trading/Hedge Fund Tracking Research Tool
Not all tracking tools are built the same. Some only show hedge fund data, while others focus on insider trades. Some are cluttered and hard to use. Others hide the best features behind a paywall.
Here’s what to look for in a high-quality free tool:
- Access to both Form 4 and 13F filings: Form 4 filings show insider buying, usually within two business days. 13F filings report hedge fund positions but are delayed by 45 days. The best tools let you see both.
- Filtering capabilities: You should be able to filter by things like dollar amount, insider role (CEO, CFO, Director), date, and whether it was a buy or a sale. For hedge funds, filters like fund name, position size, and holding period are helpful.
- Easy-to-use interface: You want to be able to scroll through trades quickly without having to read through SEC filings by hand.
- Tracking and alerts: Some tools let you follow specific companies, insiders, or hedge funds. This saves time and helps you capture key trades as they occur.
- Historical context: The best tools also show whether the insider or fund has a strong track record. For example, has this CEO bought at past lows before the stock recovered?
The right tool helps you spot the trades that matter and ignore everything else.
1. TIKR
TIKR is one of the only free platforms that provides both insider trading (Form 4) and hedge fund filings (13F) in a clean, searchable dashboard, as well as complete, end-to-end stock research. You can sort insider trades by role (e.g., CEO or CFO), transaction type, and dollar value. It’s handy for spotting “cluster buys,” where multiple insiders buy at once, which is a strong potential signal of undervaluation.
TIKR also shows which hedge funds are buying or selling specific stocks, and lets you see each fund’s complete 13F portfolio with historical changes. The data is intuitive to navigate, with helpful charts and filtering options.
Best for: All-in-one insider and fund tracking tool without needing to pay.
Below are recent insider transactions for Dollar Tree (DLTR). You can see recent Insider Transactions on over 50,000 stocks with TIKR:
TIKR also lets you track the top holdings of over 10,000 leading hedge funds through TIKR’s Track Investing Gurus feature.
This allows users to easily see what stocks hedge funds are buying and how they’re allocating their portfolio.
As an example, you can see that Warren Buffett’s Berkshire Hathaway recently reduced its stake by ~14% in Apple:

Pros
- All-in-One Platform: Combines insider trades, hedge fund ownership, financials, valuation model building, analyst estimates, earnings transcripts, and more in a single, intuitive dashboard.
- Accurate Insider Data: Clearly shows insider buying and selling activity per stock, including date, amount, and insider role.
- 13F Ownership Transparency: For any stock, you can instantly see which funds hold it, how much they own, and how their positions have recently changed.
- Zero Clutter: No ads and no distractions. Clean, professional-grade interface with a dedicated team building a better product every day.
- Incredible Value: Offers all of this (and more) at a price point lower than many single-feature tools.
Cons
- No Feed of Insider/Hedge Fund Activity Across All Stocks: You cannot browse the latest insider trades or fund buys across the entire market. You need to check insider buys stock by stock and check recent hedge fund buys fund by fund.
- Not Built Solely for Tracking Hedge Funds: Lacks niche views like “top recent buys across hedge funds” or filters by strategy (e.g., value vs. growth funds).
Bottom Line
TIKR works best for investors who already have a list of stocks or funds they want to research. If you want to dig into a specific company’s insider transactions, ownership structure, and fundamentals in one place, it delivers. If you want to scan for the hottest insider buys across the entire market, you may need to supplement with other tools.
2. OpenInsider
Open Insider is a longtime favorite for quickly scanning insider trades. The platform pulls real-time Form 4 filings and organizes them by insider name, company, date, and transaction size. You can easily filter by purchase type (e.g., only buys), role, or trade size.
The website’s layout is simple, but it gets the job done. It’s beneficial if you want to scan for recent large insider buys across the entire market.
Best for: Quickly spotting insider buying activity across companies.
Pros
- No Fluff, Just Data: Laser-focused on insider trades, which makes it extremely simple and fast to navigate.
- Useful Filters: Filter by type (buys only), market cap, sector, or cluster buying.
- Free & Fast: Loads instantly, with zero login or setup required. Great for quick checks.
- Highly Trustworthy: Uses real Form 4 data with direct links to SEC filings.
Cons
- Very Dated UI: No-frills layout feels old and can be overwhelming for new users. On the flipside, it is also convenient for experienced investors.
- No Hedge Fund Data: This tool focuses exclusively on insider trades, with no 13F tracking or fund activity.
- Not Integrated with Stock Research Tools: You cannot click into a stock to get any deeper stock research.
Bottom Line
OpenInsider works best for investors who want to quickly scan insider trades without distractions. The filters for cluster buying and buy-only transactions make it easy to spot high-conviction signals. However, if you want hedge fund data or fundamental research alongside insider activity, you will need to pair it with other tools like TIKR.
3. WhaleWisdom
Whale Wisdom focuses entirely on 13F filings and institutional ownership. You can browse top hedge funds, see their newest positions, and track how their holdings have changed over time.
One unique feature is the “WhaleScore,” which ranks funds based on past performance and position turnover. You can also view consensus picks, which are stocks held by multiple top-performing funds.
Best for: Researching hedge fund portfolios and long-term investment ideas.
Pros
- 13F Filing Focus: One of the best platforms for tracking hedge fund ownership because you can filter by fund, stock, or sector.
- Trend Analysis: See how positions have changed over time, including new buys and sold-out positions.
- WhaleScore & Rankings: Ranks funds by performance and transparency.
- Free Tier is Solid: Most key features are accessible without a subscription.
Cons
- Clunky Navigation: The interface can feel slow, crowded, and less modern than alternatives. The UX is not optimized for speed or daily use.
- Insider Trade Coverage & Stock Research is Weak: The platform is designed for hedge fund tracking, but insider trading data is minimal or nonexistent.
Bottom Line
WhaleWisdom works well for investors who want to focus specifically on 13F filings and hedge fund positioning. The trend analysis and fund rankings add useful context. However, if you need insider transaction data or deeper fundamental research, along with ownership data, you will need to pair it with other tools.

4. Insider Monkey
Insider Monkey tracks both insider trading and hedge fund activity, making it a helpful resource if you want to monitor moves from company executives and elite investors in one place. The platform highlights recent Form 4 filings and gives helpful commentary when large, unusual insider buys occur.
Insider Monkey often publishes articles that spotlight cluster buying, recent trends, and big bets from notable hedge funds, giving you more context than raw data alone. Their 13F section also tracks the top holdings of major investors like Buffett, Dalio, and Ackman.
Best for: Getting extra context behind insider and fund trades, with a mix of data and commentary.
Pros
- Articles + Data: Combines hedge fund filings with commentary, rankings, and news.
- Pre-Analyzed Lists: Offers curated views of “hedge fund favorites,” new positions, and under-the-radar stocks.
- Accessible for Beginners: The blog format and explanations make it easy to follow without technical knowledge.
Cons
- Too Much Clutter: An ad-heavy layout and frequent pop-ups can degrade the user experience.
- Lacks Precision: You do not get the clean, sortable tables that tools like TIKR or OpenInsider offer.
- Light on Raw Data: You will often get summarized opinions instead of full trade details.
Bottom Line
Insider Monkey is well-suited for investors who prefer curated content and want someone else to handle the initial screening. The editorial lens can surface interesting ideas. However, if you want to run your own analysis with clean, sortable data, you will find the platform limiting compared to more research-focused tools.

5. QuiverQuant
Quiver Quant was built for retail investors who want professional-grade data in a modern interface. Their insider trading dashboard is clean, visual, and packed with filters. You can track how many insiders are buying vs selling, when the last major purchase occurred, and which sectors are seeing the most activity.
What sets Quiver apart is how it connects insider activity to broader transparency trends. In addition to Form 4 data, Quiver shows trades from U.S. politicians, government contracts, lobbying spend, and more. This makes it a great choice if you’re interested in understanding how public sector influence intersects with stock performance.
Best for: Visualizing insider trading trends and exploring government-related investment signals.
Pros
- Unique Data Sets: Tracks not just insider trades and hedge funds, but also politician trades, government contracts, and even Reddit sentiment.
- Free & Accessible: Offers generous data at no cost.
- Insider & 13F Data is Visualized Well: Timeline charts, percent change visuals, and easy sorting make it easy to digest.
- Dashboard Filtering: You can scan recent buys and sells across insiders and funds with built-in filters.
Cons
- Lacks Context: Does not show much about insider roles, cluster buying patterns, or fund strategy. The data is helpful for headlines, but does not support deeper analysis.
- Can Feel Gimmicky: The focus on viral content with limited depth (e.g., Nancy Pelosi trades) can distract from serious research.
- Missing Integration: No earnings data, valuation models, or deep stock insights to pair with the trading activity.
Bottom Line
Quiver Quantitative is well-suited for investors seeking a quick overview of politicians’ trades, insider activity, and alternative sentiment data in one place. The visualizations make it easy to spot trends at a glance. However, if you want to dig deeper into the fundamentals behind a trade or build a full research workflow, you will need to supplement with other tools.
TL;DR:
- Use TIKR for a comprehensive research platform that combines insider and hedge fund data with deep stock analysis, valuation tools, and earnings transcripts.
- Use OpenInsider for fast, focused insider trade tracking with clean, sortable tables.
- Use WhaleWisdom to study how hedge funds build and update their portfolios over time through 13F filings.
- Use Insider Monkey if you prefer curated articles and pre-analyzed lists over raw data.
- Use Quiver Quantitative for a quick scan of politicians’ trades, insider activity, and alternative data such as Reddit sentiment.
For most investors, the best approach is to combine tools. Start with TIKR for deep research on stocks you already care about, then use OpenInsider or Quiver Quantitative to scan for new ideas across the broader market.
