Qiming Information Technology Co.,Ltd (SZSE:002232) shares have retraced a considerable 28% in the last month, reversing a fair amount of their solid recent performance. Longer-term shareholders will rue the drop in the share price, since it's now virtually flat for the year after a promising few quarters.

In spite of the heavy fall in price, Qiming Information TechnologyLtd's price-to-sales (or "P/S") ratio of 5.7x might still make it look like a sell right now compared to the wider Software industry in China, where around half of the companies have P/S ratios below 4.3x and even P/S below 2x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/S.

How Qiming Information TechnologyLtd Has Been Performing

As an illustration, revenue has deteriorated at Qiming Information TechnologyLtd over the last year, which is not ideal at all. Perhaps the market believes the company can do enough to outperform the rest of the industry in the near future, which is keeping the P/S ratio high. However, if this isn't the case, investors might get caught out paying too much for the stock.

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 Qiming Information TechnologyLtd's to be considered reasonable.

Taking a look back first, the company's revenue growth last year wasn't something to get excited about as it posted a disappointing decline of 13%. As a result, revenue from three years ago have also fallen 22% overall. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 26% shows it's an unpleasant look.

With this information, we find it concerning that Qiming Information TechnologyLtd is trading at a P/S higher than the industry. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. There's a very good chance existing shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with the recent negative growth rates.

The Bottom Line On Qiming Information TechnologyLtd's P/S

Despite the recent share price weakness, Qiming Information TechnologyLtd's P/S remains higher than most other companies in the industry. 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 Qiming Information TechnologyLtd 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. Should recent medium-term revenue trends persist, it would pose a significant risk to existing shareholders' investments and prospective investors will have a hard time accepting the current value of the stock.
