Berkshire Hathaway’s capital return machine is still running well past the quarter it was built for. Reuters reported yesterday that the conglomerate bought back roughly $2 billion of its own stock in October, extending a program that already saw about $9.6 billion repurchased in the third quarter of 2026 and some $14.4 billion across the first nine months of the year. Yet the same results release that disclosed those figures also showed profit moving the other way — a split-screen that now sits at the heart of how investors weigh the stock.
Morningstar, for its part, published an assessment today calling the shares moderately overvalued. The research house currently pegs fair value at $510 per B-share, which puts the stock about 12% above that mark. It does expect to nudge its fair-value estimate higher following yesterday’s quarterly results, and on its math adjusted operating results came in slightly ahead of its own expectations. How large that revision turns out to be — and whether the operating business can sustain it — is what will decide the stock’s appeal from here.
A Quarter That Points Two Ways
The headline numbers explain the tension. Operating profit for the third quarter of 2026 came in at $12.705 billion, down from $13.485 billion in the same period a year earlier — a decline of 6%, according to Reuters. Net earnings fell harder, to $22.112 billion from $30.796 billion. Over the longer stretch, though, the picture looks sturdier: for the first nine months of 2026, Berkshire still posted operating growth of 8%.
That gap between the quarterly dip and the nine-month advance is the crux. A durable re-rating would require Berkshire to stay on that growth path, and the conglomerate’s mix of businesses offers both the levers and the obstacles. Morningstar sees BNSF running roughly 400 basis points behind Union Pacific on profitability; closing that gap could support the company’s value, provided the railroad actually lifts its earnings — the shortfall alone sets no timetable for improvement. For shareholders, earnings quality matters more than a standalone revenue gain, since higher sales only help the valuation if they translate into lasting operating profit.
Insurance Is Where the Drag Lives
The weakness is concentrated in insurance. Underwriting profit dropped 43% in the third quarter of 2026, and investment income from the insurance operations slid 14%. Net underwriting results for the insurance and reinsurance businesses fell to $1.352 billion. Berkshire also warned of substantial economic and geopolitical uncertainty and sluggish demand across several retail operations.
One supporting factor sits in the property and casualty reinsurance book, where premiums reportedly continued to benefit from the Tokio Marine agreement. That tailwind has yet to show through in the bottom line — and for the bull case to gain traction, it would need to. Morningstar also points to risks in the energy unit, including potential charges from wildfire litigation and laws limiting investment in renewable power. Those are pressures that could make a richer valuation harder to justify even outside insurance.
Should investors sell immediately? Or is it worth buying Berkshire Hathaway?
Buybacks, but Only Below Intrinsic Value
What gives the optimistic case its footing is the growth in earnings outside insurance combined with Berkshire’s considerable financial reserves. Those resources leave room for acquisitions, equity stakes and repurchases — though value only gets created if the prices paid allow for attractive future returns. Berkshire’s buyback rule ties such purchases to a valuation below intrinsic value, a judgment the chief executive makes after consulting with the chairman. That standard argues for price discipline, so long as the earnings assumptions behind it hold up.
In the favorable scenario, the two levers reinforce each other: the operating business builds value while buybacks raise the remaining shareholders’ claim on it. Morningstar’s expected modest upgrade would then be a first step, with any further headroom having to come from additional operating progress.
The bear case is a prolonged stretch of weakness across several earnings sources at once. If underwriting stays under pressure and retail demand keeps lagging, investors would be left weighing buybacks against a still-unfavorable operating trend — and the longer that combination persists, the more a visible improvement in the business would matter. A recovery confined to one segment would likely be too little if the other stays soft.
The 13F Is the Next Marker
The next concrete checkpoint arrives on 16.11.2026, the 13F deadline, when Berkshire discloses how it is positioning its publicly traded holdings. Investors will be watching above all for whether the company’s use of capital lines up with the value creation it is targeting. After that, the real test is the operating business itself: a higher intrinsic value would be the durable foundation for further share gains, provided Berkshire backs it with growing earnings and disciplined investment.
