Investors can approximate the average market return by buying an index fund. But if you buy individual stocks, you can do both better or worse than that. That downside risk was realized by WEC Energy Group, Inc. (NYSE:WEC) shareholders over the last year, as the share price declined 14%. That's disappointing when you consider the market returned 27%. Looking at the longer term, the stock is down 13% over three years.

Now let's have a look at the company's fundamentals, and see if the long term shareholder return has matched the performance of the underlying business.

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.

Unhappily, WEC Energy Group had to report a 5.4% decline in EPS over the last year. The share price decline of 14% is actually more than the EPS drop. This suggests the EPS fall has made some shareholders are more nervous about the business.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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, WEC Energy Group's TSR for the last 1 year was -11%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

While the broader market gained around 27% in the last year, WEC Energy Group shareholders lost 11% (even including dividends). However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Longer term investors wouldn't be so upset, since they would have made 4%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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. Take risks, for example - WEC Energy Group has 2 warning signs (and 1 which is a bit unpleasant) we think you should know about.
