The Plover Bay Technologies Limited (HKG:1523) share price has done very well over the last month, posting an excellent gain of 25%. But the gains over the last month weren't enough to make shareholders whole, as the share price is still down 5.7% in the last twelve months.

Since its price has surged higher, Plover Bay Technologies' price-to-earnings (or "P/E") ratio of 12.5x might make it look like a 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 4x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.

Plover Bay Technologies certainly has been doing a good job lately as its earnings growth has been positive while most other companies have been seeing their earnings go backwards. It seems that many are expecting the company to continue defying the broader market adversity, which has increased investors' willingness to pay up for the stock. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is Plover Bay Technologies' Growth Trending?

Plover Bay Technologies' P/E ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the market.

Retrospectively, the last year delivered an exceptional 23% gain to the company's bottom line. The strong recent performance means it was also able to grow EPS by 90% in total over the last three years. Therefore, it's fair to say the earnings growth recently has been superb for the company.

Turning to the outlook, the next three years should generate growth of 15% each year as estimated by the lone analyst watching the company. Meanwhile, the rest of the market is forecast to expand by 16% per year, which is not materially different.

With this information, we find it interesting that Plover Bay Technologies is trading at a high P/E compared to the market. It seems most investors are ignoring the fairly average growth expectations and are willing to pay up for exposure to the stock. Although, additional gains will be difficult to achieve as this level of earnings growth is likely to weigh down the share price eventually.

The Final Word

Plover Bay Technologies' P/E is getting right up there since its shares have risen strongly. Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

We've established that Plover Bay Technologies currently trades on a higher than expected P/E since its forecast growth is only in line with the wider market. When we see an average earnings outlook with market-like growth, we suspect the share price is at risk of declining, sending the high P/E lower. This places shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
