With a price-to-earnings (or "P/E") ratio of 24.4x Guangzhou Baiyun Electric Equipment Co., Ltd. (SHSE:603861) may be sending bullish signals at the moment, given that almost half of all companies in China have P/E ratios greater than 38x and even P/E's higher than 75x are not unusual. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

AI is about to change healthcare. These 20 stocks are working on everything from early diagnostics to drug discovery. The best part - they are all under $10bn in marketcap - there is still time to get in early.

Recent times have been quite advantageous for Guangzhou Baiyun Electric Equipment as its earnings have been rising very briskly. It might be that many expect the strong earnings performance to degrade substantially, which has repressed the P/E. 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.

Does Growth Match The Low P/E?

The only time you'd be truly comfortable seeing a P/E as low as Guangzhou Baiyun Electric Equipment's is when the company's growth is on track to lag the market.

If we review the last year of earnings growth, the company posted a terrific increase of 57%. Still, incredibly EPS has fallen 15% in total from three years ago, which is quite disappointing. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

In contrast to the company, the rest of the market is expected to grow by 35% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

With this information, we are not surprised that Guangzhou Baiyun Electric Equipment 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.

The Final Word

While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

We've established that Guangzhou Baiyun Electric Equipment maintains its low P/E on the weakness of its sliding earnings over the medium-term, as expected. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
