Every investor on earth makes bad calls sometimes. But you want to avoid the really big losses like the plague. So spare a thought for the long term shareholders of DLH Holdings Corp. (NASDAQ:DLHC); the share price is down a whopping 78% in the last three years. That would be a disturbing experience. The more recent news is of little comfort, with the share price down 68% in a year. Shareholders have had an even rougher run lately, with the share price down 48% in the last 90 days.

With the stock having lost 11% in the past week, it's worth taking a look at business performance and seeing if there's any red flags.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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, DLH Holdings' earnings per share (EPS) dropped by 30% each year. The share price decline of 40% is actually steeper than the EPS slippage. So it's likely that the EPS decline has disappointed the market, leaving investors hesitant to buy. This increased caution is also evident in the rather low P/E ratio, which is sitting at 9.50.
