SLM's (NASDAQ:SLM) investors will be pleased with their impressive 194% return over the last five years

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%. For example, the SLM Corporation (NASDAQ:SLM) share price has soared 166% in the last half decade. Most would be very happy with that. It's down 1.1% 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.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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.

Over half a decade, SLM managed to grow its earnings per share at 22% a year. That makes the EPS growth particularly close to the yearly share price growth of 22%. Therefore one could conclude that sentiment towards the shares hasn't morphed very much. Indeed, it would appear the share price is reacting to the EPS.

The graphic below depicts how EPS has changed over time (unveil the exact values by clicking on the image).

We consider it positive that insiders have made significant purchases in the last year. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business.

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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of SLM, it has a TSR of 194% for the last 5 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

It's nice to see that SLM shareholders have received a total shareholder return of 69% over the last year. That's including the dividend. That gain is better than the annual TSR over five years, which is 24%. 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. 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.
