Tenaris (BIT:TEN) shareholders have earned a 28% CAGR over the last three years

One simple way to benefit from the stock market is to buy an index fund. But many of us dare to dream of bigger returns, and build a portfolio ourselves. For example, Tenaris S.A. (BIT:TEN) shareholders have seen the share price rise 90% over three years, well in excess of the market return (0.3%, not including dividends). However, more recent returns haven't been as impressive as that, with the stock returning just 39% in the last year , including dividends .

Let's take a look at the underlying fundamentals over the longer term, and see if they've been consistent with shareholders returns.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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.

Tenaris became profitable within the last three years. That would generally be considered a positive, so we'd expect the share price to be up.

We know that Tenaris has improved its bottom line over the last three years, but what does the future have in store? It might be well worthwhile taking a look at our free report on how its financial position has changed over time.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. In the case of Tenaris, it has a TSR of 108% for the last 3 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

It's nice to see that Tenaris shareholders have received a total shareholder return of 39% over the last year. Of course, that includes the dividend. That's better than the annualised return of 9% 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. 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.
