With a price-to-earnings (or "P/E") ratio of 24.5x The TJX Companies, Inc. (NYSE:TJX) may be sending bearish signals at the moment, given that almost half of all companies in the United States have P/E ratios under 17x and even P/E's lower than 9x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.

With its earnings growth in positive territory compared to the declining earnings of most other companies, TJX Companies has been doing quite well of late. It seems that many are expecting the company to continue defying the broader market adversity, which has increased investors' willingness to pay up for the stock. If not, then existing shareholders might be a little nervous about the viability of the share price.

What Are Growth Metrics Telling Us About The High P/E?

The only time you'd be truly comfortable seeing a P/E as high as TJX Companies' is when the company's growth is on track to outshine the market.

Retrospectively, the last year delivered an exceptional 29% gain to the company's bottom line. The latest three year period has also seen an excellent 5,165% overall rise in EPS, aided by its short-term performance. So we can start by confirming that the company has done a great job of growing earnings over that time.

Looking ahead now, EPS is anticipated to climb by 8.0% each year during the coming three years according to the analysts following the company. With the market predicted to deliver 10% growth per annum, the company is positioned for a weaker earnings result.

In light of this, it's alarming that TJX Companies' P/E sits above the majority of other companies. It seems most investors are hoping for a turnaround in the company's business prospects, but the analyst cohort is not so confident this will happen. Only the boldest would assume these prices are sustainable as this level of earnings growth is likely to weigh heavily on the share price eventually.

The Final Word

While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

We've established that TJX Companies currently trades on a much higher than expected P/E since its forecast growth is lower than the wider market. When we see a weak earnings outlook with slower than market growth, we suspect the share price is at risk of declining, sending the high P/E lower. This places shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
