Nanfang Ventilator Co., Ltd.'s (SZSE:300004) Shares Climb 30% But Its Business Is Yet to Catch Up

Those holding Nanfang Ventilator Co., Ltd. (SZSE:300004) shares would be relieved that the share price has rebounded 30% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 19% over that time.

Following the firm bounce in price, when almost half of the companies in China's Building industry have price-to-sales ratios (or "P/S") below 1.7x, you may consider Nanfang Ventilator as a stock not worth researching with its 6.1x 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.

How Is Nanfang Ventilator's Revenue Growth Trending?

In order to justify its P/S ratio, Nanfang Ventilator would need to produce outstanding growth that's well in excess of 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 10%. This means it has also seen a slide in revenue over the longer-term as revenue is down 48% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 25% shows it's an unpleasant look.

With this in mind, we find it worrying that Nanfang Ventilator'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. 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 Bottom Line On Nanfang Ventilator's P/S

The strong share price surge has lead to Nanfang Ventilator's P/S soaring as well. Using the price-to-sales ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

Our examination of Nanfang Ventilator 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. Unless the the circumstances surrounding the recent medium-term improve, it wouldn't be wrong to expect a a difficult period ahead for the company's shareholders.

We don't want to rain on the parade too much, but we did also find 1 warning sign for Nanfang Ventilator that you need to be mindful of.
