Aritzia (TSE:ATZ) investors are up 3.7% in the past week, but earnings have declined over the last five years

The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But on the bright side, you can make far more than 100% on a really good stock. For example, the Aritzia Inc. (TSE:ATZ) share price has soared 167% in the last half decade. Most would be very happy with that. On top of that, the share price is up 34% in about a quarter.

Since the stock has added CA$183m to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

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 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.

Aritzia's earnings per share are down 1.5% per year, despite strong share price performance over five years.

So it's hard to argue that the earnings per share are the best metric to judge the company, as it may not be optimized for profits at this point. Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

On the other hand, Aritzia's revenue is growing nicely, at a compound rate of 25% over the last five years. It's quite possible that management are prioritizing revenue growth over EPS growth at the moment.

It's good to see that there was some significant insider buying in the last three months. That's a positive. That said, we think earnings and revenue growth trends are even more important factors to consider. So it makes a lot of sense to check out what analysts think Aritzia will earn in the future (free profit forecasts).

A Different Perspective

It's nice to see that Aritzia shareholders have received a total shareholder return of 83% over the last year. That gain is better than the annual TSR over five years, which is 22%. Therefore it seems like sentiment around the company has been positive lately. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. 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.
