BGRIMM Technology Co., Ltd. (SHSE:600980) shares have had a horrible month, losing 26% after a relatively good period beforehand. Instead of being rewarded, shareholders who have already held through the last twelve months are now sitting on a 15% share price drop.

In spite of the heavy fall in price, there still wouldn't be many who think BGRIMM Technology's price-to-earnings (or "P/E") ratio of 27.8x is worth a mention when the median P/E in China is similar at about 28x. 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.

For instance, BGRIMM Technology's receding earnings in recent times would have to be some food for thought. One possibility is that the P/E is moderate because investors think the company might still do enough to be in line with the broader market in the near future. If you like the company, you'd at least be hoping this is the case so that you could potentially pick up some stock while it's not quite in favour.

What Are Growth Metrics Telling Us About The P/E?

There's an inherent assumption that a company should be matching the market for P/E ratios like BGRIMM Technology's to be considered reasonable.

Retrospectively, the last year delivered a frustrating 6.8% decrease to the company's bottom line. However, a few very strong years before that means that it was still able to grow EPS by an impressive 54% in total over the last three years. Accordingly, while they would have preferred to keep the run going, shareholders would probably welcome the medium-term rates of earnings growth.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 42% shows it's noticeably less attractive on an annualised basis.

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

What We Can Learn From BGRIMM Technology's P/E?

Following BGRIMM Technology's share price tumble, its P/E is now hanging on to the median market P/E. It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

Our examination of BGRIMM Technology revealed its three-year earnings trends aren't impacting its P/E as much as we would have predicted, given they look worse than current market expectations. When we see weak earnings with slower than market growth, we suspect the share price is at risk of declining, sending the moderate P/E lower. If recent medium-term earnings trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 1 warning sign with BGRIMM Technology, and understanding should be part of your investment process.
