Guangdong Tianhe Agricultural Means of Production Co., Ltd. (SZSE:002999) shares have continued their recent momentum with a 26% gain in the last month alone. The bad news is that even after the stocks recovery in the last 30 days, shareholders are still underwater by about 3.5% over the last year.

Since its price has surged higher, Guangdong Tianhe Agricultural Means of Production's price-to-earnings (or "P/E") ratio of 48.9x might make it look like a sell right now compared to the market in China, where around half of the companies have P/E ratios below 35x and even P/E's below 20x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.

As an illustration, earnings have deteriorated at Guangdong Tianhe Agricultural Means of Production over the last year, which is not ideal at all. One possibility is that the P/E is high because investors think the company will still do enough to outperform the broader market in the near future. If not, then existing shareholders may be quite nervous about the viability of the share price.

Does Growth Match The High P/E?

Guangdong Tianhe Agricultural Means of Production's P/E ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 33%. As a result, earnings from three years ago have also fallen 43% overall. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

In contrast to the company, the rest of the market is expected to grow by 39% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

With this information, we find it concerning that Guangdong Tianhe Agricultural Means of Production is trading at a P/E higher than the market. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. There's a very 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 Guangdong Tianhe Agricultural Means of Production's P/E

Guangdong Tianhe Agricultural Means of Production shares have received a push in the right direction, but its P/E is elevated too. Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

Our examination of Guangdong Tianhe Agricultural Means of Production revealed its shrinking earnings over the medium-term aren't impacting its high P/E anywhere near as much as we would have predicted, given the market is set to grow. When we see earnings heading backwards and underperforming the market forecasts, we suspect the share price is at risk of declining, sending the high P/E lower. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
