Cooper Companies (NASDAQ:COO) investors are up 4.0% in the past week, but earnings have declined over the last five years

It hasn't been the best quarter for The Cooper Companies, Inc. (NASDAQ:COO) shareholders, since the share price has fallen 17% in that time. But the silver lining is the stock is up over five years. Unfortunately its return of 14% is below the market return of 106%.

Since the stock has added US$630m to its market cap in the past week alone, let's see if underlying performance has been driving long-term 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. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Cooper Companies' earnings per share are down 2.0% per year, despite strong share price performance over five years.

Since EPS is down a bit, and the share price is up, it's probably that the market previously had some concerns about the company, but the reality has been better than feared. Having said that, if the EPS falls continue we'd be surprised to see a sustained increase in share price.

A Different Perspective

While the broader market gained around 9.3% in the last year, Cooper Companies shareholders lost 8.9%. 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 3%, 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.
