Some Confidence Is Lacking In BT Group plc's (LON:BT.A) P/E

Simply Wall St

BT Group plc's (LON:BT.A) price-to-earnings (or "P/E") ratio of 19x might make it look like a sell right now compared to the market in the United Kingdom, where around half of the companies have P/E ratios below 16x and even P/E's below 9x are quite common. However, the P/E might be high for a reason and it requires further investigation to determine if it's justified.

BT Group certainly has been doing a good job lately as it's been growing earnings more than most other companies. The P/E is probably high because investors think this strong earnings performance will continue. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Is There Enough Growth For BT Group?

BT Group's P/E ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the market.

Taking a look back first, we see that the company grew earnings per share by an impressive 24% last year. Still, incredibly EPS has fallen 17% in total from three years ago, which is quite disappointing. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Shifting to the future, estimates from the analysts covering the company suggest earnings should grow by 14% per annum over the next three years. Meanwhile, the rest of the market is forecast to expand by 15% per year, which is not materially different.

In light of this, it's curious that BT Group's P/E sits above the majority of other companies. Apparently many investors in the company are more bullish than analysts indicate and aren't willing to let go of their stock right now. These shareholders may be setting themselves up for disappointment if the P/E falls to levels more in line with the growth outlook.

The Key Takeaway

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.

We've established that BT Group currently trades on a higher than expected P/E since its forecast growth is only in line with the wider market. Right now we are uncomfortable with the relatively high share price as the predicted future earnings aren't likely to support such positive sentiment for long. Unless these conditions improve, it's challenging to accept these prices as being reasonable.
