Shenzhen Rapoo Technology Co., Ltd.'s (SZSE:002577) price-to-sales (or "P/S") ratio of 11.5x may look like a poor investment opportunity when you consider close to half the companies in the Tech industry in China have P/S ratios below 3.6x. However, the P/S might be quite high for a reason and it requires further investigation to determine if it's justified.

How Has Shenzhen Rapoo Technology Performed Recently?

It looks like revenue growth has deserted Shenzhen Rapoo Technology recently, which is not something to boast about. It might be that many are expecting an improvement to the uninspiring revenue performance over the coming period, which has kept the P/S from collapsing. 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?

The only time you'd be truly comfortable seeing a P/S as steep as Shenzhen Rapoo Technology's is when the company's growth is on track to outshine the industry decidedly.

If we review the last year of revenue, the company posted a result that saw barely any deviation from a year ago. This isn't what shareholders were looking for as it means they've been left with a 7.2% decline in revenue over the last three years in total. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Comparing that to the industry, which is predicted to deliver 17% growth in the next 12 months, the company's downward momentum based on recent medium-term revenue results is a sobering picture.

With this in mind, we find it worrying that Shenzhen Rapoo Technology's P/S exceeds that of its industry peers. 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. 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.

What Does Shenzhen Rapoo Technology's P/S Mean For Investors?

Typically, we'd caution against reading too much into price-to-sales ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

We've established that Shenzhen Rapoo Technology currently trades on a much higher than expected P/S since its recent revenues have been in decline over the medium-term. With a revenue decline on investors' minds, the likelihood of a souring sentiment is quite high which could send the P/S back in line with what we'd expect. 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.
