Hainan Expressway Co., Ltd.'s (SZSE:000886) 27% Share Price Surge Not Quite Adding Up

Despite an already strong run, Hainan Expressway Co., Ltd. (SZSE:000886) shares have been powering on, with a gain of 27% in the last thirty days. Looking back a bit further, it's encouraging to see the stock is up 48% in the last year.

Since its price has surged higher, Hainan Expressway's price-to-earnings (or "P/E") ratio of 75.9x might make it look like a strong sell right now compared to the market in China, where around half of the companies have P/E ratios below 34x and even P/E's below 20x 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.

For example, consider that Hainan Expressway'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. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is Hainan Expressway's Growth Trending?

In order to justify its P/E ratio, Hainan Expressway would need to produce outstanding growth well in excess of the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 49%. Regardless, EPS has managed to lift by a handy 23% in aggregate from three years ago, thanks to the earlier period of growth. So we can start by confirming that the company has generally done a good job of growing earnings over that time, even though it had some hiccups along the way.

This is in contrast to the rest of the market, which is expected to grow by 41% over the next year, materially higher than the company's recent medium-term annualised growth rates.

In light of this, it's alarming that Hainan Expressway'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 good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with recent growth rates.

The Key Takeaway

The strong share price surge has got Hainan Expressway's P/E rushing to great heights as well. 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.

Our examination of Hainan Expressway revealed its three-year earnings trends aren't impacting its high P/E anywhere near as much as we would have predicted, given they look worse than current market expectations. When we see weak earnings with slower than market growth, 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.
