Despite an already strong run, Emdoor Information CO.,LTD. (SZSE:001314) shares have been powering on, with a gain of 29% in the last thirty days. The last 30 days bring the annual gain to a very sharp 31%.

Even after such a large jump in price, Emdoor InformationLTD may still be sending buy signals at present with its price-to-sales (or "P/S") ratio of 2.5x, considering almost half of all companies in the Tech industry in China have P/S ratios greater than 3.3x and even P/S higher than 8x aren't out of the ordinary. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's limited.

What Does Emdoor InformationLTD's Recent Performance Look Like?

There hasn't been much to differentiate Emdoor InformationLTD's and the industry's revenue growth lately. It might be that many expect the mediocre revenue performance to degrade, which has repressed the P/S ratio. If not, then existing shareholders have reason to be optimistic about the future direction of the share price.

How Is Emdoor InformationLTD's Revenue Growth Trending?

There's an inherent assumption that a company should underperform the industry for P/S ratios like Emdoor InformationLTD's to be considered reasonable.

Retrospectively, the last year delivered an exceptional 21% gain to the company's top line. Still, revenue has fallen 11% in total from three years ago, which is quite disappointing. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenues over that time.

Turning to the outlook, the next year should generate growth of 25% as estimated by the one analyst watching the company. With the industry only predicted to deliver 17%, the company is positioned for a stronger revenue result.

In light of this, it's peculiar that Emdoor InformationLTD's P/S sits below the majority of other companies. It looks like most investors are not convinced at all that the company can achieve future growth expectations.

What Does Emdoor InformationLTD's P/S Mean For Investors?

The latest share price surge wasn't enough to lift Emdoor InformationLTD's P/S close to the industry median. 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.

A look at Emdoor InformationLTD's revenues reveals that, despite glowing future growth forecasts, its P/S is much lower than we'd expect. There could be some major risk factors that are placing downward pressure on the P/S ratio. At least price risks look to be very low, but investors seem to think future revenues could see a lot of volatility.
