As an investor its worth striving to ensure your overall portfolio beats the market average. But the risk of stock picking is that you will likely buy under-performing companies. We regret to report that long term Northwest Bancshares, Inc. (NASDAQ:NWBI) shareholders have had that experience, with the share price dropping 13% in three years, versus a market return of about 24%. The falls have accelerated recently, with the share price down 11% in the last three months. But this could be related to the weak market, which is down 8.6% in the same period.

With the stock having lost 5.4% in the past week, it's worth taking a look at business performance and seeing if there's any red flags.

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 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 three years that the share price fell, Northwest Bancshares' earnings per share (EPS) dropped by 14% each year. This fall in the EPS is worse than the 4% compound annual share price fall. So the market may not be too worried about the EPS figure, at the moment -- or it may have previously priced some of the drop in.

It's probably worth noting we've seen significant insider buying in the last quarter, which we consider a positive. On the other hand, we think the revenue and earnings trends are much more meaningful measures of the business.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. In the case of Northwest Bancshares, it has a TSR of 5.7% for the last 3 years. 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 good to see that Northwest Bancshares has rewarded shareholders with a total shareholder return of 14% in the last twelve months. That's including the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 9% 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. It's always interesting to track share price performance over the longer term. But to understand Northwest Bancshares better, we need to consider many other factors.
