The most you can lose on any stock (assuming you don’t use leverage) is 100% of your money. But when you pick a company that is really flourishing, you can make more than 100%. One great example is Berkshire Hathaway Inc. (NYSE:BRK.A) which saw its share price drive 169% higher over five years. It’s down 1.2% in the last seven days.

With that in mind, it’s worth seeing if the company’s underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

To quote Buffett, ‘Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace…’ One way to examine how market sentiment has changed over time is to look at the interaction between a company’s share price and its earnings per share (EPS).

Over half a decade, Berkshire Hathaway managed to grow its earnings per share at 56% a year. The EPS growth is more impressive than the yearly share price gain of 22% over the same period. Therefore, it seems the market has become relatively pessimistic about the company.

The image below shows how EPS has tracked over time (if you click on the image you can see greater detail).

It’s probably worth noting that the CEO is paid less than the median at similar sized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

It’s nice to see that Berkshire Hathaway shareholders have received a total shareholder return of 20% over the last year. However, that falls short of the 22% TSR per annum it has made for shareholders, each year, over five years. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
