If you buy and hold a stock for many years, you'd hope to be making a profit. Furthermore, you'd generally like to see the share price rise faster than the market. Unfortunately for shareholders, while the Alkermes plc (NASDAQ:ALKS) share price is up 17% in the last five years, that's less than the market return. Zooming in, the stock is actually down 8.5% in the last year.

Although Alkermes has shed US$315m from its market cap this week, let's take a look at its longer term fundamental trends and see if they've driven returns.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During the last half decade, Alkermes became profitable. That's generally thought to be a genuine positive, so investors may expect to see an increasing share price.

A Different Perspective

Investors in Alkermes had a tough year, with a total loss of 7.0%, against a market gain of about 19%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Longer term investors wouldn't be so upset, since they would have made 4%, each year, over five years. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend.
