TL;DR — The Bottom Line
Insider Monkey is a finance data platform that tracks hedge fund 13F filings, insider transactions, and smart-money positioning. It offers extensive free data plus a premium newsletter (from ~$9.99/month) led by Research Director Dr. Inan Dogan, with self-reported stock picks claiming to beat the S&P 500 by 66 percentage points over 3.5 years. For individual investors and professionals seeking to follow elite hedge funds and corporate insiders, Insider Monkey is one of the most specialized smart-money platforms available.
For individual investors, financial advisors, and even hedge fund analysts, one persistent question drives daily decision-making: what is the smart money doing? Insider Monkey has built its entire platform around answering that question. By aggregating 13F filings, insider transactions, and hedge fund letters into a single research hub, Insider Monkey gives users a window into the positioning of elite funds and corporate insiders—data points that historically correlate with above-average returns.
This in-depth review examines what Insider Monkey offers, how its features stack up against competitors like Seeking Alpha, GuruFocus, and TipRanks, the credibility of its performance claims, and how different types of investors can extract maximum value from the platform.

What Is Insider Monkey and Who Is It For?
Insider Monkey is a finance website and data provider that specializes in two highly valuable datasets: hedge fund 13F filings and insider trading transactions. The platform was built on a simple thesis—if ordinary investors could see what elite hedge funds and corporate insiders were buying in near real time, they could meaningfully improve their stock selection.
The audience splits across three primary user groups:
- Individual investors looking to piggyback institutional ideas without paying Bloomberg-tier fees.
- Financial advisors and RIAs who need an idea-sourcing tool and a way to validate client portfolio positioning.
- Hedge fund analysts and PMs who use Insider Monkey's hedge fund database to monitor peers, track rotations, and benchmark crowded trades.
What separates Insider Monkey from generalist financial portals is depth in a narrow lane. While Seeking Alpha competes on contributor volume and Motley Fool competes on brand-driven newsletter marketing, Insider Monkey leans into structured, filing-based data that lends itself to repeatable analytical workflows.
Core Features of the Insider Monkey Platform
Insider Monkey's product suite breaks down into four main pillars: hedge fund research, insider trading data, editorial content, and premium services. Each is designed to make smart-money tracking accessible without requiring an institutional data terminal.
Hedge Fund Research and 13F Tracking
The hedge fund center maintains profiles on hundreds of major funds, including portfolio composition, top holdings, quarterly changes, and assets under management based on disclosed 13F filings. Sample portfolios on the site can show total disclosed values exceeding $2.49 billion, with line items including ticker, share count, market value, quarter-over-quarter activity, and portfolio weight.
For an analyst, this is the kind of data that used to require manual SEC EDGAR scraping. Insider Monkey aggregates it into searchable, sortable views—ideal for spotting consensus longs, contrarian shorts, or thematic rotations across an entire cohort of funds.
Insider Trading Database and Screener
The Insider Monkey insider trading screener covers more than 1 million historical transactions. Users can filter by company, insider role (CEO, CFO, director), transaction size, and date range. The platform also publishes near-real-time pages of latest insider purchases, which is useful for spotting unusual buying clusters that often precede positive catalysts.
Editorial Content and Stock Lists
Insider Monkey publishes a high volume of editorial content—stock lists (
