Ningbo PIA Automation Holding Corp.'s (SHSE:688306) 28% Share Price Surge Not Quite Adding Up

Despite an already strong run, Ningbo PIA Automation Holding Corp. (SHSE:688306) shares have been powering on, with a gain of 28% in the last thirty days. The annual gain comes to 180% following the latest surge, making investors sit up and take notice.

Following the firm bounce in price, you could be forgiven for thinking Ningbo PIA Automation Holding is a stock to steer clear of with a price-to-sales ratios (or "P/S") of 6.4x, considering almost half the companies in China's Machinery industry have P/S ratios below 3.3x. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's so lofty.

What Does Ningbo PIA Automation Holding's Recent Performance Look Like?

We'd have to say that with no tangible growth over the last year, Ningbo PIA Automation Holding's revenue has been unimpressive. It might be that many are expecting an improvement to the uninspiring revenue performance 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.

We don't have analyst forecasts, but you can see how recent trends are setting up the company for the future by checking out our free report on Ningbo PIA Automation Holding's earnings, revenue and cash flow.

Do Revenue Forecasts Match The High P/S Ratio?

In order to justify its P/S ratio, Ningbo PIA Automation Holding would need to produce outstanding growth that's well in excess of the industry.

Retrospectively, the last year delivered virtually the same number to the company's top line as the year before. The lack of growth did nothing to help the company's aggregate three-year performance, which is an unsavory 7.0% drop in revenue. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Comparing that to the industry, which is predicted to deliver 22% growth in the next 12 months, the company's downward momentum based on recent medium-term revenue results is a sobering picture.

In light of this, it's alarming that Ningbo PIA Automation Holding's P/S sits above the majority of other companies. 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. 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.

What We Can Learn From Ningbo PIA Automation Holding's P/S?

Shares in Ningbo PIA Automation Holding have seen a strong upwards swing lately, which has really helped boost its P/S figure. We'd say the price-to-sales ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

Our examination of Ningbo PIA Automation Holding 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. Right now we aren't comfortable with the high P/S as this revenue performance is highly unlikely to support such positive sentiment for long. 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.
