The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But in contrast you can make much more than 100% if the company does well. To wit, the ESCO Technologies Inc. (NYSE:ESE) share price has flown 133% in the last three years. That sort of return is as solid as granite. In more good news, the share price has risen 23% in thirty days. We note that ESCO Technologies reported its financial results recently; luckily, you can catch up on the latest revenue and profit numbers in our company report.

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 the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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.

ESCO Technologies was able to grow its EPS at 21% per year over three years, sending the share price higher. In comparison, the 33% per year gain in the share price outpaces the EPS growth. This suggests that, as the business progressed over the last few years, it gained the confidence of market participants. It's not unusual to see the market 're-rate' a stock, after a few years of growth.

The company's earnings per share (over time) is depicted in the image below (click to see the exact numbers).

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward. This free interactive report on ESCO Technologies' earnings, revenue and cash flow is a great place to start, if you want to investigate the stock further.

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. As it happens, ESCO Technologies' TSR for the last 3 years was 136%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

We're pleased to report that ESCO Technologies shareholders have received a total shareholder return of 59% over one year. Of course, that includes the dividend. That's better than the annualised return of 12% over half a decade, implying that the company is doing better recently. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper.
