Those holding Guangzhou Ruoyuchen Technology Co.,Ltd. (SZSE:003010) shares would be relieved that the share price has rebounded 27% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 22% over that time.

Since its price has surged higher, you could be forgiven for thinking Guangzhou Ruoyuchen TechnologyLtd is a stock not worth researching with a price-to-sales ratios (or "P/S") of 1.7x, considering almost half the companies in China's Consumer Retailing industry have P/S ratios below 0.9x. However, the P/S might be high for a reason and it requires further investigation to determine if it's justified.

How Guangzhou Ruoyuchen TechnologyLtd Has Been Performing

We'd have to say that with no tangible growth over the last year, Guangzhou Ruoyuchen TechnologyLtd's revenue has been unimpressive. Perhaps the market believes that revenue growth will improve markedly over current levels, inflating the P/S ratio. If not, then existing shareholders may be a little nervous about the viability of the share price.

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

There's an inherent assumption that a company should outperform the industry for P/S ratios like Guangzhou Ruoyuchen TechnologyLtd's to be considered reasonable.

Retrospectively, the last year delivered virtually the same number to the company's top line as the year before. Still, the latest three year period was better as it's delivered a decent 10% overall rise in revenue. So it appears to us that the company has had a mixed result in terms of growing revenue over that time.

This is in contrast to the rest of the industry, which is expected to grow by 16% over the next year, materially higher than the company's recent medium-term annualised growth rates.

In light of this, it's alarming that Guangzhou Ruoyuchen TechnologyLtd's P/S sits above the majority of other companies. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. 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.

The Bottom Line On Guangzhou Ruoyuchen TechnologyLtd's P/S

The large bounce in Guangzhou Ruoyuchen TechnologyLtd's shares has lifted the company's P/S handsomely. 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.

The fact that Guangzhou Ruoyuchen TechnologyLtd currently trades on a higher P/S relative to the industry is an oddity, since its recent three-year growth is lower than the wider industry forecast. When we observe slower-than-industry revenue growth alongside a high P/S ratio, we assume there to be a significant risk of the share price decreasing, which would result in a lower P/S ratio. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these the share price as being reasonable.
