Shareholders in Edison International (NYSE:EIX) are in the red if they invested a year ago

Passive investing in an index fund is a good way to ensure your own returns roughly match the overall market. Active investors aim to buy stocks that vastly outperform the market - but in the process, they risk under-performance. Investors in Edison International (NYSE:EIX) have tasted that bitter downside in the last year, as the share price dropped 32%. That falls noticeably short of the market return of around 16%. Longer term shareholders haven't suffered as badly, since the stock is down a comparatively less painful 19% in three years. The falls have accelerated recently, with the share price down 12% in the last three months.

It's worthwhile assessing if the company's economics have been moving in lockstep with these underwhelming shareholder returns, or if there is some disparity between the two. So let's do just that.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Even though the Edison International share price is down over the year, its EPS actually improved. It could be that the share price was previously over-hyped.

It's fair to say that the share price does not seem to be reflecting the EPS growth. But we might find some different metrics explain the share price movements better.

Edison International's dividend seems healthy to us, so we doubt that the yield is a concern for the market. From what we can see, revenue is pretty flat, so that doesn't really explain the share price drop. Of course, it could simply be that it simply fell short of the market consensus expectations.

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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, Edison International's TSR for the last 1 year was -28%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

Edison International shareholders are down 28% for the year (even including dividends), but the market itself is up 16%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. On the bright side, long term shareholders have made money, with a gain of 4% per year over half a decade. 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.
