With a price-to-earnings (or "P/E") ratio of 6.9x CNOOC Limited (HKG:883) may be sending bullish signals at the moment, given that almost half of all companies in Hong Kong have P/E ratios greater than 10x and even P/E's higher than 18x are not unusual. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

CNOOC hasn't been tracking well recently as its declining earnings compare poorly to other companies, which have seen some growth on average. It seems that many are expecting the dour earnings performance to persist, which has repressed the P/E. If you still like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

Is There Any Growth For CNOOC?

The only time you'd be truly comfortable seeing a P/E as low as CNOOC's is when the company's growth is on track to lag the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 6.2%. However, a few very strong years before that means that it was still able to grow EPS by an impressive 257% in total over the last three years. Although it's been a bumpy ride, it's still fair to say the earnings growth recently has been more than adequate for the company.

Looking ahead now, EPS is anticipated to slump, contracting by 0.3% each year during the coming three years according to the analysts following the company. With the market predicted to deliver 15% growth per annum, that's a disappointing outcome.

In light of this, it's understandable that CNOOC's P/E would sit below the majority of other companies. However, shrinking earnings are unlikely to lead to a stable P/E over the longer term. Even just maintaining these prices could be difficult to achieve as the weak outlook is weighing down the shares.

The Key Takeaway

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.

As we suspected, our examination of CNOOC's analyst forecasts revealed that its outlook for shrinking earnings is contributing to its low P/E. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. It's hard to see the share price rising strongly in the near future under these circumstances.

Before you take the next step, you should know about the 2 warning signs for CNOOC (1 is concerning!) that we have uncovered.
