For many, the main point of investing is to generate higher returns than the overall market. But in any portfolio, there will be mixed results between individual stocks. So we wouldn't blame long term Lake Shore Bancorp, Inc. (NASDAQ:LSBK) shareholders for doubting their decision to hold, with the stock down 38% over a half decade. We also note that the stock has performed poorly over the last year, with the share price down 24%.

It's worthwhile assessing if the company's economics have been moving in lockstep with these underwhelming shareholder returns, or if there is some disparity between the two. So let's do just that.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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.

While the share price declined over five years, Lake Shore Bancorp actually managed to increase EPS by an average of 12% per year. Given the share price reaction, one might suspect that EPS is not a good guide to the business performance during the period (perhaps due to a one-off loss or gain). Or possibly, the market was previously very optimistic, so the stock has disappointed, despite improving EPS.

Due to the lack of correlation between the EPS growth and the falling share price, it's worth taking a look at other metrics to try to understand the share price movement.

In contrast to the share price, revenue has actually increased by 7.7% a year in the five year period. So it seems one might have to take closer look at the fundamentals to understand why the share price languishes. After all, there may be an opportunity.

What About The Total Shareholder Return (TSR)?

We'd be remiss not to mention the difference between Lake Shore Bancorp's total shareholder return (TSR) and its share price return. The TSR attempts to capture the value of dividends (as if they were reinvested) as well as any spin-offs or discounted capital raisings offered to shareholders. Lake Shore Bancorp's TSR of was a loss of 28% for the 5 years. That wasn't as bad as its share price return, because it has paid dividends.
