Those holding Jiangxi Firstar Panel Technology Co.,Ltd. (SZSE:300256) shares would be relieved that the share price has rebounded 29% 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 15% over that time.

Following the firm bounce in price, Jiangxi Firstar Panel TechnologyLtd's price-to-sales (or "P/S") ratio of 6.6x might make it look like a strong sell right now compared to other companies in the Electronic industry in China, where around half of the companies have P/S ratios below 4x and even P/S below 2x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/S.

How Has Jiangxi Firstar Panel TechnologyLtd Performed Recently?

As an illustration, revenue has deteriorated at Jiangxi Firstar Panel TechnologyLtd over the last year, which is not ideal at all. One possibility is that the P/S is high because investors think the company will still do enough to outperform the broader industry in the near future. 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 Jiangxi Firstar Panel TechnologyLtd?

There's an inherent assumption that a company should far outperform the industry for P/S ratios like Jiangxi Firstar Panel TechnologyLtd's to be considered reasonable.

Retrospectively, the last year delivered a frustrating 20% decrease to the company's top line. As a result, revenue from three years ago have also fallen 86% overall. 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 information, we find it concerning that Jiangxi Firstar Panel TechnologyLtd is trading at a P/S higher than the industry. 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 We Can Learn From Jiangxi Firstar Panel TechnologyLtd's P/S?

Our examination of Jiangxi Firstar Panel TechnologyLtd 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.
