You may think that with a price-to-sales (or "P/S") ratio of 9.9x Vtron Group Co.,Ltd. (SZSE:002308) is a stock to avoid completely, seeing as almost half of all the Electronic companies in China have P/S ratios under 4.5x and even P/S lower than 2x aren't out of the ordinary. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/S.

What Does Vtron GroupLtd's Recent Performance Look Like?

As an illustration, revenue has deteriorated at Vtron GroupLtd 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.

How Is Vtron GroupLtd's Revenue Growth Trending?

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

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 28%. This means it has also seen a slide in revenue over the longer-term as revenue is down 41% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

In contrast to the company, the rest of the industry is expected to grow by 59% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

With this in mind, we find it worrying that Vtron GroupLtd's P/S exceeds that of its industry peers. 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 Final Word

It's argued the price-to-sales ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

Our examination of Vtron GroupLtd 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.
