By buying an index fund, investors can approximate the average market return. But many of us dare to dream of bigger returns, and build a portfolio ourselves. For example, the Sempra (NYSE:SRE) share price is up 45% in the last three years, clearly besting the market return of around 21% (not including dividends). However, more recent returns haven't been as impressive as that, with the stock returning just 29% 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.

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. 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.

Sempra was able to grow its EPS at 38% per year over three years, sending the share price higher. This EPS growth is higher than the 13% average annual increase in the share price. So it seems investors have become more cautious about the company, over time.

We like that insiders have been buying shares in the last twelve months. Even so, future earnings will be far more important to whether current shareholders make money. This free interactive report on Sempra's earnings, revenue and cash flow is a great place to start, if you want to investigate the stock further.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, Sempra's TSR for the last 3 years was 61%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

Sempra provided a TSR of 29% over the last twelve months. But that return falls short of the market. The silver lining is that the gain was actually better than the average annual return of 8% per year over five year. This could indicate that the company is winning over new investors, as it pursues its strategy. 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. For example, we've discovered 2 warning signs for Sempra (1 makes us a bit uncomfortable!) that you should be aware of before investing here.
