    Greg Abel Takes Helm at Berkshire Hathaway Following Buffett Step-Down

    Question

    Greg Abel Takes Helm at Berkshire Hathaway Following Buffett Step-Down

    Direct answer

    Warren Buffett has stepped down as Berkshire Hathaway chairman, concluding a tenure that generated over 6,000,000% cumulative returns since 1965. New CEO Greg Abel now oversees capital allocation for the $1.1 trillion holding company. Abel's primary operational constraint is scale. Deploying tens of billions of dollars in excess cash without diluting overall return on equity will require active M&A or expanded return-of-capital programs.
