Sun.King Technology Group Limited's (HKG:580) 25% Share Price Surge Not Quite Adding Up

Sun.King Technology Group Limited (HKG:580) shareholders would be excited to see that the share price has had a great month, posting a 25% gain and recovering from prior weakness. Looking further back, the 13% rise over the last twelve months isn't too bad notwithstanding the strength over the last 30 days.

After such a large jump in price, Sun.King Technology Group's price-to-earnings (or "P/E") ratio of 30.3x might 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. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

With earnings growth that's exceedingly strong of late, Sun.King Technology Group has been doing very well. It seems that many are expecting the strong earnings performance to beat most other companies over the coming period, which has increased investors’ willingness to pay up for the stock. If not, then existing shareholders might be a little nervous about the viability of the share price.

Does Growth Match The High P/E?

There's an inherent assumption that a company should far outperform the market for P/E ratios like Sun.King Technology Group's to be considered reasonable.

Retrospectively, the last year delivered an exceptional 187% gain to the company's bottom line. Still, incredibly EPS has fallen 2.1% in total from three years ago, which is quite disappointing. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 22% shows it's an unpleasant look.

In light of this, it's alarming that Sun.King Technology Group's P/E sits above the majority of other companies. 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 heavily on the share price eventually.

The Final Word

Shares in Sun.King Technology Group have built up some good momentum lately, which has really inflated its P/E. We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

We've established that Sun.King Technology 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.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 2 warning signs with Sun.King Technology Group (at least 1 which is concerning), and understanding these should be part of your investment process.
