How to read this
• Open-market buys with their own money = the signal investors watch most, since insiders know the company best — but it doesn’t always mean the price will rise
• Cluster buys (2 or more insiders within 30 days) are usually seen as stronger than a single buyer
• Sells happen for many reasons — paying taxes, personal spending, or a pre-arranged “10b5-1 trading plan” — so they aren’t always a bad sign
• Stock awards, option exercises and automatic tax withholding are excluded · Only stocks tracked on this site (held by the whales) are shown
Price levels and picks are calculated automatically with the same formula for every stock — for education only, not a recommendation to buy or sell. · How it's calculated
