The SANVO Fine Chemicals Group Limited (HKG:301) share price has fared very poorly over the last month, falling by a substantial 28%. Instead of being rewarded, shareholders who have already held through the last twelve months are now sitting on a 38% share price drop.

Although its price has dipped substantially, SANVO Fine Chemicals Group's price-to-earnings (or "P/E") ratio of 58.2x might still make it look like a strong sell right now compared to the market in Hong Kong, where around half of the companies have P/E ratios below 8x and even P/E's below 5x are quite common. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.

Recent times have been quite advantageous for SANVO Fine Chemicals Group as its earnings have been rising very briskly. The P/E is probably high because investors think this strong earnings growth will be enough to outperform the broader market in the near future. If not, then existing shareholders might be a little nervous about the viability of the share price.

How Is SANVO Fine Chemicals Group's Growth Trending?

In order to justify its P/E ratio, SANVO Fine Chemicals Group would need to produce outstanding growth well in excess of the market.

Taking a look back first, we see that the company grew earnings per share by an impressive 38% last year. However, this wasn't enough as the latest three year period has seen a very unpleasant 91% drop in EPS in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 19% shows it's an unpleasant look.

In light of this, it's alarming that SANVO Fine Chemicals Group's P/E 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. There's a very good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the recent negative growth rates.

The Key Takeaway

SANVO Fine Chemicals Group's shares may have retreated, but its P/E is still flying high. It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

Our examination of SANVO Fine Chemicals Group revealed its shrinking earnings over the medium-term aren't impacting its high P/E anywhere near as much as we would have predicted, given the market is set to grow. When we see earnings heading backwards and underperforming the market forecasts, we suspect the share price is at risk of declining, sending the high P/E lower. If recent medium-term earnings trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
