CSD Water Service Co., Ltd. (SHSE:603903) Looks Inexpensive After Falling 26% But Perhaps Not Attractive Enough

CSD Water Service Co., Ltd. (SHSE:603903) shares have had a horrible month, losing 26% after a relatively good period beforehand. The drop over the last 30 days has capped off a tough year for shareholders, with the share price down 40% in that time.

Following the heavy fall in price, CSD Water Service may be sending bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 20.7x, since almost half of all companies in China have P/E ratios greater than 33x and even P/E's higher than 63x are not unusual. 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 CSD Water Service's financial performance has been poor lately as its earnings have been in decline. 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. 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 CSD Water Service's Growth Trending?

In order to justify its P/E ratio, CSD Water Service would need to produce sluggish growth that's trailing the market.

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 41%. As a result, earnings from three years ago have also fallen 61% 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 38% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

In light of this, it's understandable that CSD Water Service's P/E would sit below the majority of other companies. However, we think shrinking earnings are unlikely to lead to a stable P/E over the longer term, which could set up shareholders for future disappointment. There's potential for the P/E to fall to even lower levels if the company doesn't improve its profitability.

The Bottom Line On CSD Water Service's P/E

The softening of CSD Water Service's shares means its P/E is now sitting at a pretty low level. Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

We've established that CSD Water Service maintains its low P/E on the weakness of its sliding earnings over the medium-term, 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 moving strongly in either direction in the near future under these circumstances.
