Listen to the news

Long term investing works well, but it doesn't always work for each individual stock. It hits us in the gut when we see fellow investors suffer a loss. Spare a thought for those who held GrafTech International Ltd. (NYSE:EAF) for five whole years - as the share price tanked 84%. We also note that the stock has performed poorly over the last year, with the share price down 22%. The last week also saw the share price slip down another 22%. While a drop like that is definitely a body blow, money isn't as important as health and happiness.

With the stock having lost 22% in the past week, it's worth taking a look at business performance and seeing if there's any red flags.

GrafTech International isn't currently profitable, so most analysts would look to revenue growth to get an idea of how fast the underlying business is growing. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. 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.

In the last five years GrafTech International saw its revenue shrink by 22% per year. That's definitely a weaker result than most pre-profit companies report. So it's not that strange that the share price dropped 13% per year in that 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.

We consider it positive that insiders have made significant purchases in the last year. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business. So it makes a lot of sense to check out what analysts think GrafTech International will earn in the future (free profit forecasts).

A Different Perspective

Investors in GrafTech International had a tough year, with a total loss of 22%, against a market gain of about 16%. 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. However, the loss over the last year isn't as bad as the 13% 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. 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.
