Changzhou Aohong Electronics Co., Ltd. (SHSE:605058) shareholders are no doubt pleased to see that the share price has bounced 35% in the last month, although it is still struggling to make up recently lost ground. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 21% in the last twelve months.

Even after such a large jump in price, Changzhou Aohong Electronics' price-to-earnings (or "P/E") ratio of 22.8x 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. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

For example, consider that Changzhou Aohong Electronics' financial performance has been poor lately as its earnings have been in decline. It might be that many expect the disappointing earnings performance to continue or accelerate, 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.

How Is Changzhou Aohong Electronics' Growth Trending?

There's an inherent assumption that a company should underperform the market for P/E ratios like Changzhou Aohong Electronics' to be considered reasonable.

Retrospectively, the last year delivered a frustrating 22% 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 26% in total over the last three years. 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.

In light of this, it's understandable that Changzhou Aohong Electronics' P/E would sit below the majority of other companies. 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 Key Takeaway

Changzhou Aohong Electronics' stock might have been given a solid boost, but its P/E certainly hasn't reached any great heights. 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.

We've established that Changzhou Aohong Electronics 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. If recent medium-term earnings trends continue, it's hard to see the share price moving strongly in either direction in the near future under these circumstances.
