Despite shrinking by US$109m in the past week, Mercury General (NYSE:MCY) shareholders are still up 133% over 1 year

The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. On the other hand, if you find a high quality business to buy (at the right price) you can more than double your money! Take, for example Mercury General Corporation (NYSE:MCY). Its share price is already up an impressive 126% in the last twelve months. Also pleasing for shareholders was the 14% gain in the last three months. Having said that, the longer term returns aren't so impressive, with stock gaining just 7.8% in three years.

While the stock has fallen 3.0% this week, it's worth focusing on the longer term and seeing if the stocks historical returns have been driven by the underlying fundamentals.

Check out our latest analysis for Mercury General

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During the last year Mercury General grew its earnings per share, moving from a loss to a profit.

When a company is just on the edge of profitability it can be well worth considering other metrics in order to more precisely gauge growth (and therefore understand share price movements).

However the year on year revenue growth of 18% would help. We do see some companies suppress earnings in order to accelerate revenue growth.

The image below shows how earnings and revenue have tracked over time (if you click on the image you can see greater detail).

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. It's always worth keeping an eye on CEO pay, but a more important question is whether the company will grow earnings throughout the years.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Mercury General, it has a TSR of 133% for the last 1 year. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

It's good to see that Mercury General has rewarded shareholders with a total shareholder return of 133% in the last twelve months. Of course, that includes the dividend. That's better than the annualised return of 7% over half a decade, implying that the company is doing better recently. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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.
