Shenzhen InfoGem Technologies Co., Ltd. (SZSE:300085) shares have continued their recent momentum with a 44% gain in the last month alone. This latest share price bounce rounds out a remarkable 327% gain over the last twelve months.

Following the firm bounce in price, you could be forgiven for thinking Shenzhen InfoGem Technologies is a stock to steer clear of with a price-to-sales ratios (or "P/S") of 42.7x, considering almost half the companies in China's Software industry have P/S ratios below 7.4x. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/S.

How Shenzhen InfoGem Technologies Has Been Performing

As an illustration, revenue has deteriorated at Shenzhen InfoGem Technologies over the last year, which is not ideal at all. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/S from collapsing. If not, then existing shareholders may be quite nervous about the viability of the share price.

Do Revenue Forecasts Match The High P/S Ratio?

Shenzhen InfoGem Technologies' P/S ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the industry.

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 18%. As a result, revenue from three years ago have also fallen 32% 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 33% shows it's an unpleasant look.

With this information, we find it concerning that Shenzhen InfoGem Technologies 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. 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 Final Word

Shenzhen InfoGem Technologies' P/S has grown nicely over the last month thanks to a handy boost in the share price. While the price-to-sales ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of revenue expectations.

We've established that Shenzhen InfoGem Technologies currently trades on a much higher than expected P/S since its recent revenues have been in decline over the medium-term. Right now we aren't comfortable with the high P/S as this revenue performance is highly unlikely to support such positive sentiment for long. 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.
