Berkshire Hathaway (BRK.B) Stock Looks Undervalued As Its 82% Five Year Run Continues

Berkshire Hathaway stock has delivered an 81.8% return over 5 years, yet the latest valuation work suggests the current share price of US$512.37 still sits at a meaningful discount to an intrinsic value estimate based on the Excess Returns model.

  • Berkshire Hathaway's 81.8% return over the past 5 years points to a stock that has already rewarded patient shareholders. This makes any remaining upside case more reliant on the underlying valuation than on momentum.
  • The completed acquisition of Taylor Morrison can support long term cash flow through a larger homebuilding platform. At the same time, exposure to housing cycles and integration execution may weigh on how much value investors ultimately assign to this deal.
  • With a high value score of 5 out of 6, Berkshire Hathaway screens as broadly cheap across the main valuation checks rather than fully priced.

The issue now is whether Berkshire Hathaway's current discount to the intrinsic value estimate offers enough margin of safety once the recent share price gains and new homebuilding exposure are taken into account.

Berkshire Hathaway delivered 7.5% returns over the last year. See how this stacks up to the rest of the Diversified Financial industry.

Is Berkshire Hathaway a Bargain on Excess Returns?

The Excess Returns model looks at whether Berkshire Hathaway is earning more on its equity base than the estimated cost of that equity. For Berkshire Hathaway, the model uses a book value of $505,559.42 per share and a stable EPS estimate of $63,627.66 per share, based on the median return on equity from the past 5 years. Against a cost of equity of $39,918.67 per share, this implies an excess return of $23,709.00 per share and an average return on equity of 11.75% on a stable book value of $541,622.96 per share.

Those inputs translate to an intrinsic value estimate of $774.30 per share, compared with the recent share price of $512.37. That gap implies Berkshire Hathaway screens as around 33.8% undervalued on this Excess Returns view. Because the completed acquisition of Taylor Morrison enlarges the homebuilding platform, investors may see the current discount as reflecting both the strength of the core excess returns profile and the added execution and housing cycle risks around that deal.

On this Excess Returns analysis, Berkshire Hathaway stock currently looks undervalued relative to the estimated intrinsic value.

The Bottom Line

Berkshire Hathaway still screens as undervalued on both the Excess Returns intrinsic value estimate and the current earnings multiple, which point in the same direction rather than conflicting. That leaves the key question whether the discount is compensation for real risks, particularly around the larger homebuilding exposure after the Taylor Morrison acquisition, or whether it reflects an overly cautious view of the group’s earning power. For investors, the key consideration from here is whether Berkshire Hathaway can sustain returns that support the intrinsic value estimate and prompt the market multiple to close some of that gap.
