Hudson Technologies (NASDAQ:HDSN) shareholders are still up 889% over 5 years despite pulling back 10% in the past week

The Hudson Technologies, Inc. (NASDAQ:HDSN) share price has had a bad week, falling 10%. But that doesn't change the fact that the returns over the last half decade have been spectacular. In fact, during that period, the share price climbed 889%. Impressive! So it might be that some shareholders are taking profits after good performance. Of course what matters most is whether the business can improve itself sustainably, thus justifying a higher price. While the long term returns are impressive, we do have some sympathy for those who bought more recently, given the 40% drop, in the last year. It really delights us to see such great share price performance for investors.

While the stock has fallen 10% this week, it's worth focusing on the longer term and seeing if the stocks historical returns have been driven by the underlying fundamentals.

Check out our latest analysis for Hudson Technologies

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 the last half decade, Hudson Technologies became profitable. Sometimes, the start of profitability is a major inflection point that can signal fast earnings growth to come, which in turn justifies very strong share price gains. Since the company was unprofitable five years ago, but not three years ago, it's worth taking a look at the returns in the last three years, too. Indeed, the Hudson Technologies share price has gained 90% in three years. In the same period, EPS is up 85% per year. This EPS growth is higher than the 24% average annual increase in the share price over the same three years. So you might conclude the market is a little more cautious about the stock, these days. This cautious sentiment is reflected in its (fairly low) P/E ratio of 9.21.

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.

A Different Perspective

Hudson Technologies shareholders are down 40% for the year, but the market itself is up 33%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Longer term investors wouldn't be so upset, since they would have made 58%, each year, over five years. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. 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.
