Many investors define successful investing as beating the market average over the long term. But in any portfolio, there are likely to be some stocks that fall short of that benchmark. We regret to report that long term Avangrid, Inc. (NYSE:AGR) shareholders have had that experience, with the share price dropping 34% in three years, versus a market return of about 18%.

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.

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 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).

Although the share price is down over three years, Avangrid actually managed to grow EPS by 5.5% per year in that time. This is quite a puzzle, and suggests there might be something temporarily buoying the share price. Or else the company was over-hyped in the past, and so its growth has disappointed.

Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

We note that the dividend seems healthy enough, so that probably doesn't explain the share price drop. We like that Avangrid has actually grown its revenue over the last three years. If the company can keep growing revenue, there may be an opportunity for investors. You might have to dig deeper to understand the recent share price weakness.

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. As it happens, Avangrid's TSR for the last 3 years was -25%, 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

Avangrid shareholders are up 8.5% for the year (even including dividends). But that was short of the market average. But at least that's still a gain! Over five years the TSR has been a reduction of 2% per year, over five years. So this might be a sign the business has turned its fortunes around. 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 - Avangrid has 2 warning signs (and 1 which is a bit unpleasant) we think you should know about.
