Northland Power (TSE:NPI) shareholders are up 5.3% this past week, but still in the red over the last three years

In order to justify the effort of selecting individual stocks, it's worth striving to beat the returns from a market index fund. But if you try your hand at stock picking, you risk returning less than the market. We regret to report that long term Northland Power Inc. (TSE:NPI) shareholders have had that experience, with the share price dropping 47% in three years, versus a market return of about 28%. Furthermore, it's down 15% in about a quarter. That's not much fun for holders.

Although the past week has been more reassuring for shareholders, they're still in the red over the last three years, so let's see if the underlying business has been responsible for the decline.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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. This was, in part, due to extraordinary items impacting earnings. Since the company has fallen to a loss making position, it's hard to compare the change in EPS with the share price change. But it's safe to say we'd generally expect the share price to be lower as a result!

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for Northland Power the TSR over the last 3 years was -40%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

While the broader market gained around 21% in the last year, Northland Power shareholders lost 17% (even including dividends). Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 4% per year over five years. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. 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.
