It is a pleasure to report that the Ampco-Pittsburgh Corporation (NYSE:AP) is up 37% in the last quarter. Meanwhile over the last three years the stock has dropped hard. In that time, the share price dropped 52%. So the improvement may be a real relief to some. While many would remain nervous, there could be further gains if the business can put its best foot forward.

Although the past week has been more reassuring for shareholders, they're still in the red over the last three years, so let's see if the underlying business has been responsible for the decline.

Given that Ampco-Pittsburgh 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 desire 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 three years, Ampco-Pittsburgh grew revenue at 8.1% per year. That's a pretty good rate of top-line growth. So some shareholders would be frustrated with the compound loss of 15% per year. To be frank we're surprised to see revenue growth and share price growth diverge so strongly. It would be well worth taking a closer look at the company, to determine growth trends (and balance sheet strength).

A Different Perspective

Ampco-Pittsburgh provided a TSR of 6.1% over the last twelve months. But that was short of the market average. On the bright side, that's still a gain, and it is certainly better than the yearly loss of about 3% endured over half a decade. So this might be a sign the business has turned its fortunes around. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important. Like risks, for instance.
