CluenexBest insider trading trackers in 2026: free and paid tools for Form 4 filings
Short answer
OpenInsider is the best free insider trading tracker: fast Form 4 screens such as cluster buys and large purchases across every US company. SEC EDGAR is the free primary source. Finviz shows insider trades next to its screener. Cluenex is the pick if you want pre-planned 10b5-1 sales separated from open market buying and the trade shown next to a fair value and business check. Open market buys by executives and directors are the trades worth reading closely; most selling is pre-planned.
The numbers right now
In the 30 days to Oct 30, 2026, executives or directors bought shares on the open market at 19 of the roughly 1,000 largest US-listed companies that Cluenex covers, for $97.2M in total, while insiders sold at 239 companies for $2.4B. 67% of the dollar value sold went through pre-planned 10b5-1 sales. That is fewer companies with insider buying than the 12-month average of 60 per month.

Questions people ask
What is the best free insider trading tracker?
OpenInsider is the most useful free tracker for screening Form 4 filings across every US company. SEC EDGAR is the free primary source. Cluenex publishes free monthly statistics on insider buying and selling across about 1,000 large US stocks.
Should I ignore insider selling under 10b5-1 plans?
Mostly. A 10b5-1 plan sets up sales in advance, often for taxes or diversification, so a planned sale says little about what the insider expects. Open market purchases are rarer and more informative, because insiders usually buy for one reason.
Which insider trades are worth following?
Open market purchases by the chief executive, chief financial officer or several directors at once (a cluster buy), especially when the amount is large relative to their pay. Option exercises, grants and pre-planned sales carry much less information.
