ACM Research, Inc. (NASDAQ:ACMR) shareholders have seen the share price descend 25% over the month. But over five years returns have been remarkably great. Indeed, the share price is up a whopping 310% in that time. Arguably, the recent fall is to be expected after such a strong rise. But the real question is whether the business fundamentals can improve over the long term. Unfortunately not all shareholders will have held it for five years, so spare a thought for those caught in the 42% decline over the last three years: that's a long time to wait for profits.
While this past week has detracted from the company's five-year return, let's look at the recent trends of the underlying business and see if the gains have been in alignment.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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.
Over half a decade, ACM Research managed to grow its earnings per share at 70% a year. This EPS growth is higher than the 33% average annual increase in the share price. So one could conclude that the broader market has become more cautious towards the stock.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

A Different Perspective
It's good to see that ACM Research has rewarded shareholders with a total shareholder return of 101% in the last twelve months. That gain is better than the annual TSR over five years, which is 33%. Therefore it seems like sentiment around the company has been positive lately. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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.
