Passive investing in an index fund is a good way to ensure your own returns roughly match the overall market. While individual stocks can be big winners, plenty more fail to generate satisfactory returns. Unfortunately the Pathfinder Bancorp, Inc. (NASDAQ:PBHC) share price slid 25% over twelve months. That contrasts poorly with the market return of 26%. On the bright side, the stock is actually up 23% in the last three years.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Unhappily, Pathfinder Bancorp had to report a 23% decline in EPS over the last year. This proportional reduction in earnings per share isn't far from the 25% decrease in the share price. Given the lower EPS we might have expected investors to lose confidence in the stock, but that doesn't seemed to have happened. Instead, the change in the share price seems to reduction in earnings per share, alone.
