Terna – Rete Elettrica Nazionale Società per Azioni (BIT:TRN) is currently trading at a trailing P/E of 13.5x, which is higher than the industry average of 13.5x. Although some investors may jump to the conclusion that you should avoid the stock or sell if you own it, understanding the assumptions behind the P/E ratio might change your mind. Today, I will deconstruct the P/E ratio and highlight what you need to be careful of when using the P/E ratio. View our latest analysis for Terna – Rete Elettrica Nazionale Società per Azioni

What you need to know about the P/E ratio

BIT:TRN PE PEG Gauge Jun 14th 18

The P/E ratio is a popular ratio used in relative valuation since earnings power is a key driver of investment value. It compares a stock’s price per share to the stock’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 company’s earnings.

P/E Calculation for TRN

Price-Earnings Ratio = Price per share ÷ Earnings per share

TRN Price-Earnings Ratio = €4.63 ÷ €0.342 = 13.5x

On its own, the P/E ratio doesn’t tell you much; however, it becomes extremely useful when you compare it with other similar companies. We want to compare the stock’s P/E ratio to the average of companies that have similar characteristics as TRN, such as size and country of operation. A common peer group is companies that exist in the same industry, which is what I use. TRN’s P/E of 13.5x is higher than its industry peers (13.5x), which implies that each dollar of TRN’s earnings is being overvalued by investors. Therefore, according to this analysis, TRN is an over-priced stock.

Assumptions to watch out for

However, before you rush out to sell your TRN shares, it is important to note that this conclusion is based on two key assumptions. The first is that our “similar companies” are actually similar to TRN, or else the difference in P/E might be a result of other factors. For example, if you compared higher growth firms with TRN, then its P/E would naturally be lower since investors would reward its peers’ higher growth with a higher price. The second assumption that must hold true is that the stocks we are comparing TRN to are fairly valued by the market. If this does not hold, there is a possibility that TRN’s P/E is lower because our peer group is overvalued by the market.

What this means for you:

You may have already conducted fundamental analysis on the stock as a shareholder, so its current overvaluation could signal a potential selling opportunity to reduce your exposure to TRN. Now that you understand the ins and outs of the PE metric, you should know to bear in mind its limitations before you make an investment decision. 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.
