While Old Second Bancorp, Inc. (NASDAQ:OSBC) shareholders are probably generally happy, the stock hasn't had particularly good run recently, with the share price falling 19% in the last quarter. But that scarcely detracts from the really solid long term returns generated by the company over five years. We think most investors would be happy with the 125% return, over that period. Generally speaking the long term returns will give you a better idea of business quality than short periods can. Ultimately business performance will determine whether the stock price continues the positive long term trend.

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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, Old Second Bancorp managed to grow its earnings per share at 7.5% a year. This EPS growth is slower than the share price growth of 18% per year, over the same period. So it's fair to assume the market has a higher opinion of the business than it did five years ago. That's not necessarily surprising considering the five-year track record of earnings growth.

We consider it positive that insiders have made significant purchases in the last year. Even so, future earnings will be far more important to whether current shareholders make money.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Old Second Bancorp the TSR over the last 5 years was 139%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

We're pleased to report that Old Second Bancorp shareholders have received a total shareholder return of 9.0% over one year. That's including the dividend. However, that falls short of the 19% TSR per annum it has made for shareholders, each year, over five years. The pessimistic view would be that be that the stock has its best days behind it, but on the other hand the price might simply be moderating while the business itself continues to execute. Investors who like to make money usually check up on insider purchases, such as the price paid, and total amount bought.
