# Is It Time To Buy Noble Midstream Partners LP (NYSE:NBLX) Based Off Its PE Ratio?

Noble Midstream Partners LP (NYSE:NBLX) is trading with a trailing P/E of 10.7x, which is lower than the industry average of 12.7x. Although some investors may jump to the conclusion that this is a great buying opportunity, understanding the assumptions behind the P/E ratio might change your mind. In this article, I will break down what the P/E ratio is, how to interpret it and what to watch out for. See our latest analysis for Noble Midstream Partners

### Breaking down the P/E ratio

P/E is often used for relative valuation since earnings power is a chief driver of investment value. It compares a stockâ€™s price per share to the stockâ€™s earnings per share. A more intuitive way of understanding the P/E ratio is to think of it as how much investors are paying for each dollar of the companyâ€™s earnings.

P/E Calculation for NBLX

Price-Earnings Ratio = Price per share Ã· Earnings per share

NBLX Price-Earnings Ratio = \$44 Ã· \$4.098 = 10.7x

The P/E ratio isnâ€™t a metric you view in isolation and only becomes useful when you compare it against other similar companies. We preferably want to compare the stockâ€™s P/E ratio to the average of companies that have similar features to NBLX, such as capital structure and profitability. One way of gathering a peer group is to use firms in the same industry, which is what Iâ€™ll do. At 10.7x, NBLXâ€™s P/E is lower than its industry peers (12.7x). This implies that investors are undervaluing each dollar of NBLXâ€™s earnings. As such, our analysis shows that NBLX represents an under-priced stock.

### Assumptions to be aware of

Before you jump to the conclusion that NBLX is the perfect buying opportunity, it is important to realise that our conclusion rests on two assertions. Firstly, our peer group contains companies that are similar to NBLX. If this isnâ€™t the case, the difference in P/E could be due to other factors. For example, if you compared higher growth firms with NBLX, then its P/E would naturally be lower since investors would reward its peersâ€™ higher growth with a higher price. The second assumption that must hold true is that the stocks we are comparing NBLX to are fairly valued by the market. If this does not hold true, NBLXâ€™s lower P/E ratio may be because firms in our peer group are overvalued by the market.

### What this means for you:

Since you may have already conducted your due diligence on NBLX, the undervaluation of the stock may mean it is a good time to top up on your current holdings. But at the end of the day, keep in mind that relative valuation relies heavily on critical assumptions Iâ€™ve outlined above. Remember that basing your investment decision off one metric alone is certainly not sufficient. There are many things I have not taken into account in this article and the PE ratio is very one-dimensional.
