How these figures are made

As of Oct 26, 2026: insiders filed 527 buys ($1.1B) and 2,075 sales ($7.6B) in December 2025, 0.25 buys per sale. Scores as of Dec 31, 2025's close.

Shares bought or sold on the market. The buys and sales officers, directors, and 10% owners filed on Form 4s, never grants, option exercises, gifts, or shares held back for taxes.
Plan sales left out. Sales a Form 4 marks as made under a 10b5-1 trading plan set up in advance are not counted, as the Insiders list leaves them out. Buys so marked are counted, as the list counts them, and tagged Plan.
By the filing date. A trade counts in the month its Form 4 was filed, the day the public could read it.
One trade, once. A trade reported by more than one owner of the same shares (a fund and its general partner) counts once. A move between two filers on one day at one price, and a price in another currency or share unit, are left out.
Dollars as filed. Shares times the price on the filing. The buy/sell ratio counts trades, not dollars. The record reaches back to trades made on Oct 7, 2025.
