Costain Group PLC (LON:COST) shareholders are doubtless heartened to see the share price bounce 33% in just one week. But will that heal all the wounds inflicted over 5 years of declines? Unlikely. Five years have seen the share price descend precipitously, down a full 91%. So we don't gain too much confidence from the recent recovery. The important question is if the business itself justifies a higher share price in the long term. While a drop like that is definitely a body blow, money isn't as important as health and happiness.

While the last five years has been tough for Costain Group shareholders, this past week has shown signs of promise. So let's look at the longer term fundamentals and see if they've been the driver of the negative returns.

Given that Costain Group 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. Shareholders of unprofitable companies usually expect strong revenue growth. That's because it's hard to be confident a company will be sustainable if revenue growth is negligible, and it never makes a profit.

Over half a decade Costain Group reduced its trailing twelve month revenue by 12% for each year. That's definitely a weaker result than most pre-profit companies report. So it's not altogether surprising to see the share price down 14% per year in the same time period. We don't think this is a particularly promising picture. Of course, the poor performance could mean the market has been too severe selling down. That can happen.

A Different Perspective

While the broader market lost about 4.7% in the twelve months, Costain Group shareholders did even worse, losing 19%. However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. However, the loss over the last year isn't as bad as the 14% per annum loss investors have suffered over the last half decade. We'd need to see some sustained improvements in the key metrics before we could muster much enthusiasm. 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.
