It might seem bad, but the worst that can happen when you buy a stock (without leverage) is that its share price goes to zero. But in contrast you can make much more than 100% if the company does well. For example, the Schlumberger Limited (NYSE:SLB) share price has soared 243% in the last three years. Most would be happy with that. And in the last month, the share price has gained 16%.

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

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 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).

During three years of share price growth, Schlumberger moved from a loss to profitability. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here.

You can see how EPS has changed over time in the image below (click on the chart to see the exact values).

It is of course excellent to see how Schlumberger has grown profits over the years, but the future is more important for shareholders. Take a more thorough look at Schlumberger's financial health with this free report on its balance sheet.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, Schlumberger's TSR for the last 3 years was 263%, which exceeds the share price return mentioned earlier. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

We're pleased to report that Schlumberger shareholders have received a total shareholder return of 23% over one year. And that does include the dividend. That certainly beats the loss of about 2% per year over the last half decade. We generally put more weight on the long term performance over the short term, but the recent improvement could hint at a (positive) inflection point within the business. 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.
