Sign inThe shared column is the reading: companies both sides name in their own filings. BLK names 6 counterparties, BRK-B names 0, and none appears on both lists. A shared supplier is a fact each company filed separately, not a measured dependency between the two.
BRK-B names no counterparty in its filings, so there is nothing to intersect.
Two filed statements on one plate. Each side is drawn as a share of its own revenue, so band length reads as margin, never as company size. BLK keeps 32.0¢ of every revenue dollar to BRK-B's 25.3¢. By revenue, BRK-B's quarter is 21.2× BLK's, a fact this drawing states rather than draws.
Standardized lines from each company's own filing. The two quarters end 730 days apart, which this page states rather than hides: BLK Jun 30 '24, BRK-B Jun 30 '26. The gap column is a margin difference in percentage points, never a price direction, so it takes no colour and no caret.
