With a price-to-earnings (or "P/E") ratio of 9.9x Commercial Metals Company (NYSE:CMC) may be sending bullish signals at the moment, given that almost half of all companies in the United States have P/E ratios greater than 17x and even P/E's higher than 32x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/E.

Recent times haven't been advantageous for Commercial Metals as its earnings have been falling quicker than most other companies. It seems that many are expecting the dismal earnings performance to persist, which has repressed the P/E. If you still like the company, you'd want its earnings trajectory to turn around before making any decisions. Or at the very least, you'd be hoping the earnings slide doesn't get any worse if your plan is to pick up some stock while it's out of favour.

Does Growth Match The Low P/E?

Commercial Metals' P/E ratio would be typical for a company that's only expected to deliver limited growth, and importantly, perform worse than the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 34%. Even so, admirably EPS has lifted 168% in aggregate from three years ago, notwithstanding the last 12 months. Although it's been a bumpy ride, it's still fair to say the earnings growth recently has been more than adequate for the company.

Shifting to the future, estimates from the seven analysts covering the company suggest earnings growth is heading into negative territory, declining 2.5% per year over the next three years. Meanwhile, the broader market is forecast to expand by 10% per annum, which paints a poor picture.

With this information, we are not surprised that Commercial Metals is trading at a P/E lower than the market. Nonetheless, there's no guarantee the P/E has reached a floor yet with earnings going in reverse. There's potential for the P/E to fall to even lower levels if the company doesn't improve its profitability.

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.

We've established that Commercial Metals maintains its low P/E on the weakness of its forecast for sliding earnings, as expected. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. It's hard to see the share price rising strongly in the near future under these circumstances.
