The past three years for Northland Power (TSE:NPI) investors has not been profitable

As an investor its worth striving to ensure your overall portfolio beats the market average. But the risk of stock picking is that you will likely buy under-performing companies. We regret to report that long term Northland Power Inc. (TSE:NPI) shareholders have had that experience, with the share price dropping 51% in three years, versus a market return of about 22%. And over the last year the share price fell 36%, so we doubt many shareholders are delighted. Furthermore, it's down 14% in about a quarter. That's not much fun for holders.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

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. 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.

Over the three years that the share price declined, Northland Power's earnings per share (EPS) dropped significantly, falling to a loss. Extraordinary items contributed to this situation. Since the company has fallen to a loss making position, it's hard to compare the change in EPS with the share price change. However, we can say we'd expect to see a falling share price in this scenario.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Northland Power, it has a TSR of -45% for the last 3 years. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

While the broader market gained around 10.0% in the last year, Northland Power shareholders lost 33% (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 1.7%, 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. It's always interesting to track share price performance over the longer term. But to understand Northland Power better, we need to consider many other factors.
