Prices are the closing price on the transaction date, not what was paid: filings never disclose an execution price. Blank figures mean the window has not elapsed yet. Sales are not scored — a sale closes a position rather than opening one — so the 15 disclosed sales of MMM are not in this table.

Download the data behind this page, or read how every figure is calculated. Trades in MMM are a small part of the full rankings, which score each member across everything they bought.
