Investors can buy low cost index fund if they want to receive the average market return. But if you invest in individual stocks, some are likely to underperform. That's what has happened with the CNB Financial Corporation (NASDAQ:CCNE) share price. It's up 11% over three years, but that is below the market return. Unfortunately, the share price has fallen 3.0% over twelve months.

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.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

During three years of share price growth, CNB Financial achieved compound earnings per share growth of 5.7% per year. The average annual share price increase of 4% is actually lower than the EPS growth. So one could reasonably conclude that the market has cooled on the stock. This cautious sentiment is reflected in its (fairly low) P/E ratio of 8.73.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for CNB Financial the TSR over the last 3 years was 22%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

CNB Financial shareholders gained a total return of 0.6% during the year. Unfortunately this falls short of the market return. It's probably a good sign that the company has an even better long term track record, having provided shareholders with an annual TSR of 3% over five years. 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.
