The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But on a lighter note, a good company can see its share price rise well over 100%. One great example is Federal Agricultural Mortgage Corporation (NYSE:AGM) which saw its share price drive 165% higher over five years. Also pleasing for shareholders was the 18% gain in the last three months. But this could be related to the strong market, which is up 13% in the last three months.

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. 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 five years of share price growth, Federal Agricultural Mortgage achieved compound earnings per share (EPS) growth of 12% per year. This EPS growth is slower than the share price growth of 22% per year, over the same period. So it's fair to assume the market has a higher opinion of the business than it did five years ago. And that's hardly shocking given the track record of growth.

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. We note that for Federal Agricultural Mortgage the TSR over the last 5 years was 218%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

It's good to see that Federal Agricultural Mortgage has rewarded shareholders with a total shareholder return of 41% in the last twelve months. And that does include the dividend. That gain is better than the annual TSR over five years, which is 26%. Therefore it seems like sentiment around the company has been positive lately. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important. Consider for instance, the ever-present spectre of investment risk.
