## Common questions

- What does Berkshire Hathaway own? [Berkshire Hathaway's latest 13F](https://www.moatshark.com/m/berkshire-hathaway), with buys, sells, its 5% stakes and its Japanese holdings. Greg Abel has been chief executive since 1 January 2026; Warren Buffett, CEO until the end of 2025, has been chairman emeritus since 18 September 2026, so recent trades are not his.
