If you want to compound wealth in the stock market, you can do so by buying an index fund. But investors can boost returns by picking market-beating companies to own shares in. For example, the Amerant Bancorp Inc. (NYSE:AMTB) share price is up 32% in the last 1 year, clearly besting the market return of around 21% (not including dividends). So that should have shareholders smiling. The longer term returns have not been as good, with the stock price only 6.4% higher than it was three years ago.

After a strong gain in the past week, it's worth seeing if longer term returns have been driven by improving fundamentals.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. 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, Amerant Bancorp actually saw its earnings per share drop 66%.

Given the share price gain, we doubt the market is measuring progress with EPS. Indeed, when EPS is declining but the share price is up, it often means the market is considering other factors.

We are skeptical of the suggestion that the 1.6% dividend yield would entice buyers to the stock. We think that the revenue growth of 3.1% could have some investors interested. Many businesses do go through a phase where they have to forgo some profits to drive business development, and sometimes its for the best.

It is of course excellent to see how Amerant Bancorp has grown profits over the years, but the future is more important for shareholders. You can see how its balance sheet has strengthened (or weakened) over time in this free interactive graphic.

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 Amerant Bancorp, it has a TSR of 34% 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 Amerant Bancorp shareholders have received a total shareholder return of 34% over the last year. Of course, that includes the dividend. That gain is better than the annual TSR over five years, which is 4%. Therefore it seems like sentiment around the company has been positive lately. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. It's always interesting to track share price performance over the longer term. But to understand Amerant Bancorp better, we need to consider many other factors.
