It's not a stretch to say that Shandong Taihe Technologies Co., Ltd.'s (SZSE:300801) price-to-earnings (or "P/E") ratio of 37.1x right now seems quite "middle-of-the-road" compared to the market in China, where the median P/E ratio is around 36x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/E.

For instance, Shandong Taihe Technologies' receding earnings in recent times would have to be some food for thought. It might be that many expect the company to put the disappointing earnings performance behind them over the coming period, which has kept the P/E from falling. If not, then existing shareholders may be a little nervous about the viability of the share price.

Is There Some Growth For Shandong Taihe Technologies?

In order to justify its P/E ratio, Shandong Taihe Technologies would need to produce growth that's similar to the market.

Retrospectively, the last year delivered a frustrating 40% decrease to the company's bottom line. This means it has also seen a slide in earnings over the longer-term as EPS is down 21% in total over the last three years. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 41% shows it's an unpleasant look.

With this information, we find it concerning that Shandong Taihe Technologies is trading at a fairly similar P/E to the market. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. There's a good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the recent negative growth rates.

The Bottom Line On Shandong Taihe Technologies' 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 Shandong Taihe Technologies revealed its shrinking earnings over the medium-term aren't impacting its P/E as much as we would have predicted, given the market is set to grow. Right now we are uncomfortable with the P/E as this earnings performance is unlikely to support a more positive sentiment for long. Unless the recent medium-term conditions improve, it's challenging to accept these prices as being reasonable.
