Insurance, railroads, energy, investments. We rebuild its market value from the price, split it into its parts, and compare its multiples with those of its largest competitors.
Verified figures, not advice. Every number on this page comes from the company's own filings or from exchange prices, and the source is linked. Every calculation is shown, so you can repeat it. What we do not do is tell you what a share should be worth or whether to buy it: that depends on your goals and on forecasts, and no multiple can settle it. This is a snapshot: prices of 12 Oct 2026, company results up to mid 2026. Found a mistake? Tell us and we correct it.

What investors pay beyond the accounts
For banks and insurers, debt and deposits are raw material, not financing. Enterprise value and EBITDA do not describe them, so we do not build them. Value is read against equity: market value is $1.11tn and book equity is $747.9bn, a price to book of 1.5x.
Banks and insurers are compared on price to earnings, price to book and dividend yield. Dividend yield is shown for information and has no "vs median".
Chubb, Progressive and Travelers are insurers. Berkshire also owns railroads, utilities and manufacturing, so insurers cover only part of it.
- P/E: 12.9x against a peer median of 11.0x (mean 10.7x). Difference to the median: +18%.
- Price to book: 1.5x against a peer median of 2.3x (mean 2.6x). Difference: -37%.
These are descriptions of today's prices, not forecasts. "n.m." means not meaningful, for example negative profit.

Questions people ask
Does a higher multiple than competitors mean the share is overvalued?
No. It means investors pay more per dollar of sales or profit. The reason can be faster growth, higher margins or lower risk, or it can be excess optimism. A multiple gap is a question to investigate, not an answer.
Why not use enterprise value for a bank or insurer?
Their debt and deposits are the raw material of the business, not a way of financing it, so enterprise value would mislead. Value is read against equity instead.
Why show both the mean and the median of competitors?
The mean is pulled up by one extreme value. The median is the middle value and resists outliers. When they differ a lot, trust the median more.
