Nanya New Material Technology Co.,Ltd (SHSE:688519) shareholders won't be pleased to see that the share price has had a very rough month, dropping 27% and undoing the prior period's positive performance. The drop over the last 30 days has capped off a tough year for shareholders, with the share price down 17% in that time.

Since its price has dipped substantially, Nanya New Material TechnologyLtd's price-to-sales (or "P/S") ratio of 1.4x might make it look like a buy right now compared to the Electronic industry in China, where around half of the companies have P/S ratios above 3.2x and even P/S above 6x are quite common. 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 Nanya New Material TechnologyLtd's Recent Performance Look Like?

For instance, Nanya New Material TechnologyLtd's receding revenue in recent times would have to be some food for thought. Perhaps the market believes the recent revenue performance isn't good enough to keep up the industry, causing the P/S ratio to suffer. Those who are bullish on Nanya New Material TechnologyLtd will be hoping that this isn't the case so that they can pick up the stock at a lower valuation.

Do Revenue Forecasts Match The Low P/S Ratio?

In order to justify its P/S ratio, Nanya New Material TechnologyLtd would need to produce sluggish growth that's trailing 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 7.5%. The last three years don't look nice either as the company has shrunk revenue by 2.6% in aggregate. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenue over that time.

Comparing that to the industry, which is predicted to deliver 25% 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 understandable that Nanya New Material TechnologyLtd's P/S would sit below the majority of other companies. Nonetheless, there's no guarantee the P/S has reached a floor yet with revenue going in reverse. Even just maintaining these prices could be difficult to achieve as recent revenue trends are already weighing down the shares.

The Key Takeaway

The southerly movements of Nanya New Material TechnologyLtd's shares means its P/S is now sitting at a pretty low level. Generally, our preference is to limit the use of the price-to-sales ratio to establishing what the market thinks about the overall health of a company.

Our examination of Nanya New Material TechnologyLtd confirms that the company's shrinking revenue over the past medium-term is a key factor in its low price-to-sales ratio, given the industry is projected to grow. At this stage investors feel the potential for an improvement in revenue isn't great enough to justify a higher P/S ratio. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
