The total return for Energy Recovery (NASDAQ:ERII) investors has risen faster than earnings growth over the last five years

Energy Recovery, Inc. (NASDAQ:ERII) shareholders have seen the share price descend 12% over the month. But at least the stock is up over the last five years. However we are not very impressed because the share price is only up 94%, less than the market return of 95%. While the returns over the last 5 years have been good, we do feel sorry for those shareholders who haven't held shares that long, because the share price is down 31% in the last three years.

Since the long term performance has been good but there's been a recent pullback of 9.7%, let's check if the fundamentals match the share price.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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 five years of share price growth, Energy Recovery achieved compound earnings per share (EPS) growth of 16% per year. So the EPS growth rate is rather close to the annualized share price gain of 14% per year. That suggests that the market sentiment around the company hasn't changed much over that time. Rather, the share price has approximately tracked EPS growth.

A Different Perspective

We regret to report that Energy Recovery shareholders are down 3.0% for the year. Unfortunately, that's worse than the broader market decline of 2.0%. Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. On the bright side, long term shareholders have made money, with a gain of 14% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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.
