We think intelligent long term investing is the way to go. But no-one is immune from buying too high. For example the Air New Zealand Limited (NZSE:AIR) share price dropped 78% over five years. That's not a lot of fun for true believers. Furthermore, it's down 14% in about a quarter. That's not much fun for holders.

Since shareholders are down over the longer term, lets look at the underlying fundamentals over the that time and see if they've been consistent with returns.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just 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.

Air New Zealand became profitable within the last five years. That would generally be considered a positive, so we are surprised to see the share price is down. Other metrics may better explain the share price move.

Arguably, the revenue drop of 9.1% a year for half a decade suggests that the company can't grow in the long term. That could explain the weak share price.

What About The Total Shareholder Return (TSR)?

We'd be remiss not to mention the difference between Air New Zealand's total shareholder return (TSR) and its share price return. 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. Air New Zealand's TSR of was a loss of 57% for the 5 years. That wasn't as bad as its share price return, because it has paid dividends.



A Different Perspective

We regret to report that Air New Zealand shareholders are down 8.0% for the year. Unfortunately, that's worse than the broader market decline of 1.4%. Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. Unfortunately, longer term shareholders are suffering worse, given the loss of 9% doled out over the last five years. We'd need to see some sustained improvements in the key metrics before we could muster much enthusiasm. It's always interesting to track share price performance over the longer term. But to understand Air New Zealand better, we need to consider many other factors. For example, we've discovered 1 warning sign for Air New Zealand that you should be aware of before investing here.
