For many, the main point of investing in the stock market is to achieve spectacular returns. While not every stock performs well, when investors win, they can win big. For example, the RadNet, Inc. (NASDAQ:RDNT) share price is up a whopping 348% in the last half decade, a handsome return for long term holders. This just goes to show the value creation that some businesses can achieve. On top of that, the share price is up 40% in about a quarter.

On the back of a solid 7-day performance, let's check what role the company's fundamentals have played in driving long term shareholder returns.

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. 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.

We know that RadNet has been profitable in the past. However, it made a loss in the last twelve months, suggesting profit may be an unreliable metric at this stage. So it might be better to look at other metrics to try to understand the share price.

In contrast revenue growth of 11% per year is probably viewed as evidence that RadNet is growing, a real positive. It's quite possible that management are prioritizing revenue growth over EPS growth at the moment.

A Different Perspective

RadNet shareholders are up 16% for the year. But that was short of the market average. If we look back over five years, the returns are even better, coming in at 35% per year for five years. It's quite possible the business continues to execute with prowess, even as the share price gains are slowing. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
