Unpleasant Surprises Could Be In Store For Newmark Security plc's (LON:NWT) Shares

With a price-to-earnings (or "P/E") ratio of 56x Newmark Security plc (LON:NWT) may be sending very bearish signals at the moment, given that almost half of all companies in the United Kingdom have P/E ratios under 15x 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 so lofty.

For example, consider that Newmark Security's financial performance has been poor lately as its earnings have been in decline. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/E from collapsing. If not, then existing shareholders may be quite nervous about the viability of the share price.

How Is Newmark Security's Growth Trending?

There's an inherent assumption that a company should far outperform the market for P/E ratios like Newmark Security's to be considered reasonable.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 62%. As a result, earnings from three years ago have also fallen 11% overall. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 18% shows it's an unpleasant look.

In light of this, it's alarming that Newmark Security's P/E sits above the majority of other companies. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. There's a very good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the recent negative growth rates.

The Final Word

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.

We've established that Newmark Security currently trades on a much higher than expected P/E since its recent earnings have been in decline over the medium-term. Right now we are increasingly uncomfortable with the high P/E as this earnings performance is highly unlikely to support such positive sentiment for long. If recent medium-term earnings trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 3 warning signs with Newmark Security (at least 2 which are a bit concerning), and understanding these should be part of your investment process.

Of course, you might find a fantastic investment by looking at a few good candidates. So take a peek at this free list of companies with a strong growth track record, trading on a low P/E.
