Sundy Service Group Co. Ltd's (HKG:9608) 26% Share Price Plunge Could Signal Some Risk

Sundy Service Group Co. Ltd (HKG:9608) shares have retraced a considerable 26% in the last month, reversing a fair amount of their solid recent performance. Instead of being rewarded, shareholders who have already held through the last twelve months are now sitting on a 45% share price drop.

In spite of the heavy fall in price, Sundy Service Group's price-to-earnings (or "P/E") ratio of 59.7x 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 9x 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.

For example, consider that Sundy Service Group's financial performance has been poor lately as its earnings have been in decline. One possibility is that the P/E is high because investors think the company will still do enough to outperform the broader market in the near future. If not, then existing shareholders may be quite nervous about the viability of the share price.

How Is Sundy Service Group's Growth Trending?

The only time you'd be truly comfortable seeing a P/E as steep as Sundy Service Group's is when the company's growth is on track to outshine the market decidedly.

Retrospectively, the last year delivered a frustrating 49% decrease to the company's bottom line. This means it has also seen a slide in earnings over the longer-term as EPS is down 82% in total over the last three years. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

In contrast to the company, the rest of the market is expected to grow by 21% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

With this information, we find it concerning that Sundy Service Group is trading at a P/E higher than the market. 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 Final Word

Even after such a strong price drop, Sundy Service Group's P/E still exceeds the rest of the market significantly. 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 Sundy Service Group currently trades on a much 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 high P/E lower. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
