Air Canada (TSE:AC) shareholders have endured a 56% loss from investing in the stock five years ago

Generally speaking long term investing is the way to go. But unfortunately, some companies simply don't succeed. For example the Air Canada (TSE:AC) share price dropped 56% over five years. We certainly feel for shareholders who bought near the top. And we doubt long term believers are the only worried holders, since the stock price has declined 20% over the last twelve months.

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.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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.

During five years of share price growth, Air Canada moved from a loss to profitability. Most would consider that to be a good thing, so it's counter-intuitive to see the share price declining. Other metrics may better explain the share price move.

In contrast to the share price, revenue has actually increased by 5.9% a year in the five year period. So it seems one might have to take closer look at the fundamentals to understand why the share price languishes. After all, there may be an opportunity.

The image below shows how earnings and revenue have tracked over time (if you click on the image you can see greater detail).

It's probably worth noting we've seen significant insider buying in the last quarter, which we consider a positive. That said, we think earnings and revenue growth trends are even more important factors to consider.

A Different Perspective

Air Canada shareholders are down 20% for the year, but the market itself is up 15%. 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 9% per year over five years. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. It's always interesting to track share price performance over the longer term. But to understand Air Canada better, we need to consider many other factors. Take risks, for example - Air Canada has 2 warning signs (and 1 which doesn't sit too well with us) we think you should know about.
