SiS International Holdings Limited (HKG:529) Stock Rockets 28% But Many Are Still Ignoring The Company

SiS International Holdings Limited (HKG:529) shares have continued their recent momentum with a 28% gain in the last month alone. Looking further back, the 18% rise over the last twelve months isn't too bad notwithstanding the strength over the last 30 days.

In spite of the firm bounce in price, SiS International Holdings may still be sending very bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 3.4x, since almost half of all companies in Hong Kong have P/E ratios greater than 13x and even P/E's higher than 28x are not unusual. However, the P/E might be quite low for a reason and it requires further investigation to determine if it's justified.

Recent times have been quite advantageous for SiS International Holdings as its earnings have been rising very briskly. It might be that many expect the strong earnings performance to degrade substantially, which has repressed the P/E. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

What Are Growth Metrics Telling Us About The Low P/E?

The only time you'd be truly comfortable seeing a P/E as depressed as SiS International Holdings' is when the company's growth is on track to lag the market decidedly.

If we review the last year of earnings growth, the company posted a terrific increase of 91%. The strong recent performance means it was also able to grow EPS by 139% in total over the last three years. Therefore, it's fair to say the earnings growth recently has been superb for the company.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 21% shows it's noticeably more attractive on an annualised basis.

With this information, we find it odd that SiS International Holdings is trading at a P/E lower than the market. It looks like most investors are not convinced the company can maintain its recent growth rates.

What We Can Learn From SiS International Holdings' P/E?

SiS International Holdings' recent share price jump still sees its P/E sitting firmly flat on the ground. 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.

Our examination of SiS International Holdings revealed its three-year earnings trends aren't contributing to its P/E anywhere near as much as we would have predicted, given they look better than current market expectations. When we see strong earnings with faster-than-market growth, we assume potential risks are what might be placing significant pressure on the P/E ratio. It appears many are indeed anticipating earnings instability, because the persistence of these recent medium-term conditions would normally provide a boost to the share price.
