Where several insiders bought at once
What this meansOne insider buying can be noise. Several executives and directors buying in the same quarter is one of the stronger signals in public data, though it is never a guarantee.

What this meansInsiders almost always sell more than they buy, through stock awards and diversification. Watch for months when buying rises.

FAQ
Reading insider trades
Short answers to the questions we hear most.
Who counts as an insider?
Officers, directors and anyone owning more than 10% of a company’s shares. They must report trades in that company’s stock on SEC Form 4, usually within two business days.
What is a 10b5-1 plan?
A pre-arranged trading plan set up in advance, often to sell shares on a schedule. Planned sales say little about an insider’s current view, so we flag them.
Why focus on purchases?
Insiders sell for taxes, diversification or a new house. Buying with their own cash in the open market is rarer and more telling, especially when several insiders do it together.
