There's no doubt that investing in the stock market is a truly brilliant way to build wealth. But not every stock you buy will perform as well as the overall market. For example, the Cathay General Bancorp (NASDAQ:CATY), share price is up over the last year, but its gain of 24% trails the market return. However, the stock hasn't done so well in the longer term, with the stock only up 1.8% in three years.

Now it's worth having a look at the company's fundamentals too, because that will help us determine if the long term shareholder return has matched the performance of the underlying business.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During the last year, Cathay General Bancorp actually saw its earnings per share drop 22%.

Given the share price gain, we doubt the market is measuring progress with EPS. Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

Unfortunately Cathay General Bancorp's fell 8.7% 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.

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. It's always worth keeping an eye on CEO pay, but a more important question is whether the company will grow earnings throughout the years.

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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for Cathay General Bancorp the TSR over the last 1 year was 28%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

Cathay General Bancorp shareholders gained a total return of 28% during the year. But that return falls short of the market. The silver lining is that the gain was actually better than the average annual return of 8% per year over five year. It is possible that returns will improve along with the business fundamentals. 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.
