Net income is as reported (GAAP), so it includes one-off items and, for some companies, gains or losses on investments they hold. Companies that report under IFRS (most non-US companies) or whose shares we can’t match reliably are left out; “portfolio covered” shows how much is included. Look-through earnings explained. Growth compares earnings per share over the last 12 months with the 12 months a year earlier, for holdings profitable in both.

5% stake filings

Holdings of 5% or more of a company (13D and 13G), usually reported well before the next 13F. How this works

Weitz Investment Management’s filings since December 2024, newest first. An amendment showing less than 5% means the holding fell below the threshold. A 13D means the holder may seek to influence the company. How to read a 13D.
