It is doubtless a positive to see that the Allegiant Travel Company (NASDAQ:ALGT) share price has gained some 33% in the last three months. Meanwhile over the last three years the stock has dropped hard. Indeed, the share price is down a tragic 65% in the last three years. So it is really good to see an improvement. The rise has some hopeful, but turnarounds are often precarious.

If the past week is anything to go by, investor sentiment for Allegiant Travel isn't positive, so let's see if there's a mismatch between fundamentals and the share price.

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 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.

During five years of share price growth, Allegiant Travel moved from a loss to profitability. We would usually expect to see the share price rise as a result. So it's worth looking at other metrics to try to understand the share price move.

We note that, in three years, revenue has actually grown at a 31% annual rate, so that doesn't seem to be a reason to sell shares. It's probably worth investigating Allegiant Travel further; while we may be missing something on this analysis, there might also be an opportunity.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

A Different Perspective

While the broader market gained around 20% in the last year, Allegiant Travel shareholders lost 18% (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. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 7% over the last half decade. 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. It's always interesting to track share price performance over the longer term. But to understand Allegiant Travel better, we need to consider many other factors.
