Some Confidence Is Lacking In Ashtead Group plc's (LON:AHT) P/E

With a price-to-earnings (or "P/E") ratio of 21.6x Ashtead Group plc (LON:AHT) may be sending bearish signals at the moment, given that almost half of all companies in the United Kingdom have P/E ratios under 16x and even P/E's lower than 9x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's as high as it is.

Ashtead Group could be doing better as its earnings have been going backwards lately while most other companies have been seeing positive earnings growth. It might be that many expect the dour earnings performance to recover substantially, which has kept the P/E from collapsing. If not, then existing shareholders may be extremely nervous about the viability of the share price.

Does Growth Match The High P/E?

In order to justify its P/E ratio, Ashtead Group would need to produce impressive growth in excess of the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 6.6%. Still, the latest three year period has seen an excellent 53% overall rise in EPS, in spite of its unsatisfying short-term performance. So we can start by confirming that the company has generally done a very good job of growing earnings over that time, even though it had some hiccups along the way.

Shifting to the future, estimates from the analysts covering the company suggest earnings should grow by 14% per annum over the next three years. That's shaping up to be similar to the 13% each year growth forecast for the broader market.

In light of this, it's curious that Ashtead Group'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. Although, additional gains will be difficult to achieve as this level of earnings growth is likely to weigh down the share price eventually.

The Key Takeaway

We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

Our examination of Ashtead Group's analyst forecasts revealed that its market-matching earnings outlook isn't impacting its high P/E as much as we would have predicted. 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. This places shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
