Those holding Shanghai Menon Animal Nutrition Technology Co., Ltd. (SZSE:301156) shares would be relieved that the share price has rebounded 29% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 14% in the last twelve months.

Even after such a large jump in price, Shanghai Menon Animal Nutrition Technology's price-to-earnings (or "P/E") ratio of 25.4x might still make it look like a buy right now compared to the market in China, where around half of the companies have P/E ratios above 32x and even P/E's above 58x are quite common. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's limited.

For example, consider that Shanghai Menon Animal Nutrition Technology's financial performance has been pretty ordinary lately as earnings growth is non-existent. One possibility is that the P/E is low because investors think this benign earnings growth rate will likely underperform the broader market in the near future. 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 out of favour.

How Is Shanghai Menon Animal Nutrition Technology's Growth Trending?

The only time you'd be truly comfortable seeing a P/E as low as Shanghai Menon Animal Nutrition Technology's is when the company's growth is on track to lag the market.

Retrospectively, the last year delivered virtually the same number to the company's bottom line as the year before. This isn't what shareholders were looking for as it means they've been left with a 12% decline in EPS over the last three years in total. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Comparing that to the market, which is predicted to deliver 41% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.

With this information, we are not surprised that Shanghai Menon Animal Nutrition Technology is trading at a P/E lower than the market. Nonetheless, there's no guarantee the P/E has reached a floor yet with earnings going in reverse. There's potential for the P/E to fall to even lower levels if the company doesn't improve its profitability.

What We Can Learn From Shanghai Menon Animal Nutrition Technology's P/E?

The latest share price surge wasn't enough to lift Shanghai Menon Animal Nutrition Technology's P/E close to the market median. Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

As we suspected, our examination of Shanghai Menon Animal Nutrition Technology revealed its shrinking earnings over the medium-term are contributing to its low P/E, given the market is set to grow. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio.
