The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But when you pick a company that is really flourishing, you can make more than 100%. One great example is PennyMac Financial Services, Inc. (NYSE:PFSI) which saw its share price drive 269% higher over five years. Also pleasing for shareholders was the 15% gain in the last three months.

After a strong gain in the past week, it's worth seeing if longer term returns have been driven by improving fundamentals.

Check out our latest analysis for PennyMac Financial Services

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. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During five years of share price growth, PennyMac Financial Services actually saw its EPS drop 0.8% per year.

By glancing at these numbers, we'd posit that the decline in earnings per share is not representative of how the business has changed over the years. Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

We doubt the modest 1.0% dividend yield is attracting many buyers to the stock. The revenue growth of 0.7% per year hardly seems impressive. So why is the share price up? It's not immediately obvious to us, but a closer look at the company's progress over time might yield answers.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, PennyMac Financial Services' TSR for the last 5 years was 291%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

We're pleased to report that PennyMac Financial Services shareholders have received a total shareholder return of 39% over one year. That's including the dividend. That's better than the annualised return of 31% over half a decade, implying that the company is doing better recently. 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.
