There wouldn't be many who think ACM Research, Inc.'s (NASDAQ:ACMR) price-to-earnings (or "P/E") ratio of 16.9x is worth a mention when the median P/E in the United States is similar at about 17x. Although, it's not wise to simply ignore the P/E without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

With its earnings growth in positive territory compared to the declining earnings of most other companies, ACM Research has been doing quite well of late. It might be that many expect the strong earnings performance to deteriorate like the rest, which has kept the P/E from rising. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's not quite in favour.

Does Growth Match The P/E?

ACM Research's P/E ratio would be typical for a company that's only expected to deliver moderate growth, and importantly, perform in line with the market.

Taking a look back first, we see that the company grew earnings per share by an impressive 64% last year. The strong recent performance means it was also able to grow EPS by 351% in total over the last three years. Therefore, it's fair to say the earnings growth recently has been superb for the company.

Shifting to the future, estimates from the seven analysts covering the company suggest earnings should grow by 10% per annum over the next three years. With the market predicted to deliver 13% growth each year, the company is positioned for a weaker earnings result.

With this information, we find it interesting that ACM Research is trading at a fairly similar P/E to the market. Apparently many investors in the company are less bearish than analysts indicate and aren't willing to let go of their stock right now. These shareholders may be setting themselves up for future disappointment if the P/E falls to levels more in line with the growth outlook.

The Key Takeaway

We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

We've established that ACM Research currently trades on a higher than expected P/E since its forecast growth is lower than the wider market. Right now we are uncomfortable with the P/E as the predicted future earnings aren't likely to support a more positive sentiment for long. Unless these conditions improve, it's challenging to accept these prices as being reasonable.
