These days it's easy to simply buy an index fund, and your returns should (roughly) match the market. But you can significantly boost your returns by picking above-average stocks. For example, the BankFinancial Corporation (NASDAQ:BFIN) share price is up 28% in the last 1 year, clearly besting the market return of around 21% (not including dividends). So that should have shareholders smiling. However, the longer term returns haven't been so impressive, with the stock up just 18% in the last three years.

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

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 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.

During the last year, BankFinancial actually saw its earnings per share drop 56%.

This means it's unlikely the market is judging the company based on earnings growth. Therefore, it seems likely that investors are putting more weight on metrics other than EPS, at the moment.

Unfortunately BankFinancial's fell 12% over twelve months. So using a snapshot of key business metrics doesn't give us a good picture of why the market is bidding up the stock.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

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. In the case of BankFinancial, it has a TSR of 33% for the last 1 year. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

It's nice to see that BankFinancial shareholders have received a total shareholder return of 33% over the last year. Of course, that includes the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 7% per year), it would seem that the stock's performance has improved in recent times. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. 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.
