Energy International Investments Holdings Limited (HKG:353) shares have continued their recent momentum with a 29% gain in the last month alone. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 11% over that time.

Since its price has surged higher, Energy International Investments Holdings' price-to-earnings (or "P/E") ratio of 41x 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 8x and even P/E's below 4x 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 instance, Energy International Investments Holdings' receding earnings in recent times would have to be some food for thought. 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.

Is There Enough Growth For Energy International Investments Holdings?

Energy International Investments Holdings' P/E ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the market.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 62%. At least EPS has managed not to go completely backwards from three years ago in aggregate, thanks to the earlier period of growth. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

Comparing that to the market, which is predicted to deliver 23% growth in the next 12 months, the company's momentum is weaker based on recent medium-term annualised earnings results.

In light of this, it's alarming that Energy International Investments Holdings' 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. 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 Key Takeaway

The strong share price surge has got Energy International Investments Holdings' P/E rushing to great heights as well. 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 Energy International Investments Holdings 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. If recent medium-term earnings trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 3 warning signs with Energy International Investments Holdings, and understanding them should be part of your investment process.
