Does Growth Match The High P/E?

Sinopec Oilfield Service's 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 26%. Even so, admirably EPS has lifted 335% in aggregate from three years ago, notwithstanding the last 12 months. Accordingly, while they would have preferred to keep the run going, shareholders would probably welcome the medium-term rates of earnings growth.

Looking ahead now, EPS is anticipated to climb by 19% during the coming year according to the two analysts following the company. That's shaping up to be similar to the 20% growth forecast for the broader market.

In light of this, it's curious that Sinopec Oilfield Service's P/E sits above the majority of other companies. It seems most investors are ignoring the fairly average growth expectations and are willing to pay up for exposure to the stock. These shareholders may be setting themselves up for disappointment if the P/E falls to levels more in line with the growth outlook.
