To the annoyance of some shareholders, Kehua Holdings Co.,Ltd (SHSE:603161) shares are down a considerable 30% in the last month, which continues a horrid run for the company. Instead of being rewarded, shareholders who have already held through the last twelve months are now sitting on a 34% share price drop.

After such a large drop in price, when close to half the companies operating in China's Auto Components industry have price-to-sales ratios (or "P/S") above 2x, you may consider Kehua HoldingsLtd as an enticing stock to check out with its 0.6x P/S ratio. However, the P/S might be low for a reason and it requires further investigation to determine if it's justified.

What Does Kehua HoldingsLtd's Recent Performance Look Like?

Kehua HoldingsLtd certainly has been doing a great job lately as it's been growing its revenue at a really rapid pace. It might be that many expect the strong revenue performance to degrade substantially, which has repressed the P/S ratio. Those who are bullish on Kehua HoldingsLtd will be hoping that this isn't the case, so that they can pick up the stock at a lower valuation.

What Are Revenue Growth Metrics Telling Us About The Low P/S?

The only time you'd be truly comfortable seeing a P/S as low as Kehua HoldingsLtd's is when the company's growth is on track to lag the industry.

If we review the last year of revenue growth, the company posted a terrific increase of 32%. The latest three year period has also seen an excellent 65% overall rise in revenue, aided by its short-term performance. Therefore, it's fair to say the revenue growth recently has been superb for the company.

Comparing the recent medium-term revenue trends against the industry's one-year growth forecast of 25% shows it's noticeably less attractive.

With this information, we can see why Kehua HoldingsLtd is trading at a P/S lower than the industry. 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 Final Word

Kehua HoldingsLtd's recently weak share price has pulled its P/S back below other Auto Components companies. Using the price-to-sales 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.

Our examination of Kehua HoldingsLtd confirms that the company's revenue trends over the past three-year years are a key factor in its low price-to-sales ratio, as we suspected, given they fall short of current industry expectations. Right now shareholders are accepting the low P/S as they concede future revenue 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.
