It's been a soft week for Greene County Bancorp, Inc. (NASDAQ:GCBC) shares, which are down 10%. But that scarcely detracts from the really solid long term returns generated by the company over five years. Indeed, the share price is up an impressive 122% in that time. We think it's more important to dwell on the long term returns than the short term returns. Only time will tell if there is still too much optimism currently reflected in the share price.

Although Greene County Bancorp has shed US$60m from its market cap this week, let's take a look at its longer term fundamental trends and see if they've driven returns.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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.

Over half a decade, Greene County Bancorp managed to grow its earnings per share at 7.3% a year. This EPS growth is lower than the 17% average annual increase in the share price. So it's fair to assume the market has a higher opinion of the business than it did five years ago. And that's hardly shocking given the track record of growth.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. As it happens, Greene County Bancorp's TSR for the last 5 years was 139%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

Greene County Bancorp shareholders are up 4.8% for the year (even including dividends). Unfortunately this falls short of the market return. On the bright side, the longer term returns (running at about 19% a year, over half a decade) look better. It's quite possible the business continues to execute with prowess, even as the share price gains are slowing. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
