Zhejiang Zhengguang Industrial Co., Ltd. (SZSE:301092) Stock Rockets 36% As Investors Are Less Pessimistic Than Expected

Zhejiang Zhengguang Industrial Co., Ltd. (SZSE:301092) shares have had a really impressive month, gaining 36% after a shaky period beforehand. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 14% over that time.

In spite of the firm bounce in price, there still wouldn't be many who think Zhejiang Zhengguang Industrial's price-to-earnings (or "P/E") ratio of 33x is worth a mention when the median P/E in China is similar at about 34x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/E.

As an illustration, earnings have deteriorated at Zhejiang Zhengguang Industrial over the last year, which is not ideal at all. It might be that many expect the company to put the disappointing earnings performance behind them over the coming period, which has kept the P/E from falling. If not, then existing shareholders may be a little nervous about the viability of the share price.

Does Growth Match The P/E?

In order to justify its P/E ratio, Zhejiang Zhengguang Industrial would need to produce growth that's similar to the market.

Retrospectively, the last year delivered a frustrating 41% decrease to the company's bottom line. As a result, earnings from three years ago have also fallen 37% overall. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Comparing that to the market, which is predicted to deliver 37% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.

With this information, we find it concerning that Zhejiang Zhengguang Industrial is trading at a fairly similar P/E to the market. 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 earnings trends is likely to weigh on the share price eventually.

The Final Word

Zhejiang Zhengguang Industrial appears to be back in favour with a solid price jump getting its P/E back in line with most other companies. Using the price-to-earnings 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.

We've established that Zhejiang Zhengguang Industrial currently trades on a higher than expected P/E since its recent earnings have been in decline over the medium-term. When we see earnings heading backwards and underperforming the market forecasts, we suspect the share price is at risk of declining, sending the moderate P/E lower. If recent medium-term earnings trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
