What China New Energy Limited's (HKG:1156) 33% Share Price Gain Is Not Telling You

Despite an already strong run, China New Energy Limited (HKG:1156) shares have been powering on, with a gain of 33% in the last thirty days. The last 30 days bring the annual gain to a very sharp 37%.

Following the firm bounce in price, you could be forgiven for thinking China New Energy is a stock not worth researching with a price-to-sales ratios (or "P/S") of 1.1x, considering almost half the companies in Hong Kong's Construction industry have P/S ratios below 0.3x. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's as high as it is.

Do Revenue Forecasts Match The High P/S Ratio?

China New Energy's P/S ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the industry.

Retrospectively, the last year delivered an exceptional 56% gain to the company's top line. Despite this strong recent growth, it's still struggling to catch up as its three-year revenue frustratingly shrank by 57% overall. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 18% shows it's an unpleasant look.

In light of this, it's alarming that China New Energy's P/S sits above the majority of other companies. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. Only the boldest would assume these prices are sustainable as a continuation of recent revenue trends is likely to weigh heavily on the share price eventually.

What We Can Learn From China New Energy's P/S?

The large bounce in China New Energy's shares has lifted the company's P/S handsomely. Generally, our preference is to limit the use of the price-to-sales ratio to establishing what the market thinks about the overall health of a company.

Our examination of China New Energy revealed its shrinking revenue over the medium-term isn't resulting in a P/S as low as we expected, given the industry is set to grow. When we see revenue heading backwards and underperforming the industry forecasts, we feel the possibility of the share price declining is very real, bringing the P/S back into the realm of reasonability. Unless the the circumstances surrounding the recent medium-term improve, it wouldn't be wrong to expect a a difficult period ahead for the company's shareholders.
