Shareholders have had an even rougher run lately, with the share price down 22% in the last 90 days.

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 flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During the three years that the share price fell, Advanced Medical Solutions Group's earnings per share (EPS) dropped by 7.4% each year. The share price decline of 16% is actually steeper than the EPS slippage. So it's likely that the EPS decline has disappointed the market, leaving investors hesitant to buy.
