Unfortunately for some shareholders, the Shanghai Lingyun Industries Development Co., Ltd (SHSE:900957) share price has dived 41% in the last thirty days, prolonging recent pain. For any long-term shareholders, the last month ends a year to forget by locking in a 69% share price decline.

Although its price has dipped substantially, given about half the companies in China have price-to-earnings ratios (or "P/E's") above 30x, you may still consider Shanghai Lingyun Industries Development as a highly attractive investment with its 12.1x P/E ratio. However, the P/E might be quite low for a reason and it requires further investigation to determine if it's justified.

For instance, Shanghai Lingyun Industries Development's receding earnings in recent times would have to be some food for thought. One possibility is that the P/E is low because investors think the company won't do enough to avoid underperforming the broader market in the near future. However, if this doesn't eventuate then existing shareholders may be feeling optimistic about the future direction of the share price.

Does Growth Match The Low P/E?

The only time you'd be truly comfortable seeing a P/E as depressed as Shanghai Lingyun Industries Development's is when the company's growth is on track to lag the market decidedly.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 24%. That put a dampener on the good run it was having over the longer-term as its three-year EPS growth is still a noteworthy 12% in total. Although it's been a bumpy ride, it's still fair to say the earnings growth recently has been mostly respectable for the company.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 36% shows it's noticeably less attractive on an annualised basis.

In light of this, it's understandable that Shanghai Lingyun Industries Development's P/E sits below the majority of other companies. It seems most investors are expecting to see the recent limited growth rates continue into the future and are only willing to pay a reduced amount for the stock.

The Key Takeaway

Having almost fallen off a cliff, Shanghai Lingyun Industries Development's share price has pulled its P/E way down as well. 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.

We've established that Shanghai Lingyun Industries Development maintains its low P/E on the weakness of its recent three-year growth being lower than the wider market forecast, as expected. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. If recent medium-term earnings trends continue, it's hard to see the share price rising strongly in the near future under these circumstances.
