Average price paid is weighted by shares, so a large purchase counts for more than a small one. It is what insiders reported paying, not a target or a fair value.

Insider flow: Net buying by value — a count of disclosed transactions, not a rating or a recommendation.

Insider transaction timeline

Every reported transaction, positioned by trade date. Purchases sit above the axis, sales below; circle area is proportional to dollar value. No share-price line is drawn — this feed carries transaction prices only, and a price history inferred from them would imply market data the filings do not contain.
