Berkshire Hathaway (BRK.A) Stock Could Be Below Fair Value After Its 79% Run

Simply Wall St·09/22/2026 10:21:30
Listen to the news

Berkshire Hathaway has delivered a 78.8% share price gain over the past 5 years, and the question now is whether that long run is still supported by the returns the group earns on the capital it controls. A major leadership handover and fresh headlines around key subsidiaries mean investors are looking at the stock less as a Warren Buffett story and more as a test of how efficiently the conglomerate can keep compounding its own money.

  • The 78.8% return over 5 years puts a lot of faith in Berkshire Hathaway’s ability to keep earning solid returns on a very large capital base, which makes the quality and durability of those returns the central issue.
  • Warren Buffett’s move to chairman emeritus while Howard Buffett becomes chair and Greg Abel continues to run operations can reshape how quickly and where capital is deployed inside the group, which matters for how much profit Berkshire can earn on every dollar it retains and reinvests.
  • If you'd rather focus on earnings, this one's for you. See what Berkshire Hathaway's 12.5x P/E says about the price.

The issue now is whether Berkshire Hathaway’s current share price is fully justified by the returns it earns on its capital across its mix of insurers, industrial assets and financial investments.

Is Berkshire Hathaway a Bargain on Excess Returns?

The Excess Returns model looks at how much profit Berkshire Hathaway can generate over and above the return shareholders typically require on its equity. Berkshire Hathaway shows a book value of $522,225.90 per share and a stable EPS estimate of $65,244.04 per share, which implies that past profitability on equity has been strong enough to support a sizeable earnings base without relying on dividends. With an average return on equity of 11.91% and a per share cost of equity of $40,959.42, the model estimates an excess return of $24,284.62 per share and a stable book value of $547,710.90 per share based on analyst expectations.

Those excess returns are what drive the model’s view that estimated intrinsic value sits substantially above the current share price of $752,180.01. Warren Buffett stepping back to chairman emeritus, while Howard Buffett and Greg Abel formalise the succession, helps explain why some investors may question how repeatable those excess returns are, even as the model suggests the underlying economics of Berkshire Hathaway remain robust at the current price.
