There's Reason For Concern Over Routon Electronic Co., Ltd.'s (SHSE:600355) Massive 28% Price Jump

Those holding Routon Electronic Co., Ltd. (SHSE:600355) shares would be relieved that the share price has rebounded 28% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Taking a wider view, although not as strong as the last month, the full year gain of 15% is also fairly reasonable.

Since its price has surged higher, when almost half of the companies in China's Tech industry have price-to-sales ratios (or "P/S") below 3.2x, you may consider Routon Electronic as a stock not worth researching with its 13.4x P/S ratio. 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 Routon Electronic's Recent Performance Look Like?

For instance, Routon Electronic's receding revenue in recent times would have to be some food for thought. 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. However, if this isn't the case, investors might get caught out paying too much for the stock.

Is There Enough Revenue Growth Forecasted For Routon Electronic?

Routon Electronic's 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.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 16%. The last three years don't look nice either as the company has shrunk revenue by 24% in aggregate. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

In contrast to the company, the rest of the industry is expected to grow by 25% 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 Routon Electronic'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.

The Bottom Line On Routon Electronic's P/S

The strong share price surge has lead to Routon Electronic's P/S soaring as well. 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.

We've established that Routon Electronic currently trades on a much higher than expected P/S since its recent revenues have been in decline over the medium-term. 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.
