Serko Limited (NZSE:SKO) shareholders should be happy to see the share price up 21% in the last quarter. But that doesn't change the fact that the returns over the last three years have been less than pleasing. After all, the share price is down 47% in the last three years, significantly under-performing the market.

So let's have a look and see if the longer term performance of the company has been in line with the underlying business' progress.

Check out our latest analysis for Serko

Given that Serko didn't make a profit in the last twelve months, we'll focus on revenue growth to form a quick view of its business development. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. Some companies are willing to postpone profitability to grow revenue faster, but in that case one would hope for good top-line growth to make up for the lack of earnings.

In the last three years, Serko saw its revenue grow by 51% per year, compound. That's well above most other pre-profit companies. The share price drop of 14% per year over three years would be considered disappointing by many, so you might argue the company is getting little credit for its impressive revenue growth. It seems likely that actual growth fell short of shareholders' expectations. Before considering a purchase, investors should consider how quickly expenses are growing, relative to revenue.

A Different Perspective

Serko shareholders are down 9.6% for the year, but the market itself is up 11%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 5% 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.
