Investing in Ampco-Pittsburgh (NYSE:AP) three years ago would have delivered you a 72% gain

Ampco-Pittsburgh Corporation (NYSE:AP) shareholders have seen the share price descend 13% over the month. But that shouldn't obscure the pleasing returns achieved by shareholders over the last three years. To wit, the share price did better than an index fund, climbing 72% during that period.

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

Ampco-Pittsburgh isn't currently profitable, so most analysts would look to revenue growth to get an idea of how fast the underlying business is growing. Shareholders of unprofitable companies usually expect strong revenue growth. That's because fast revenue growth can be easily extrapolated to forecast profits, often of considerable size.

Ampco-Pittsburgh actually saw its revenue drop by 8.7% per year over three years. Despite the lack of revenue growth, the stock has returned 20%, compound, over three years. Unless the company is going to make profits soon, we would be pretty cautious about it.

A Different Perspective

Investors in Ampco-Pittsburgh had a tough year, with a total loss of 20%, against a market gain of about 1.4%. 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 10% over the last half decade. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business.
