When close to half the companies in the United States have price-to-earnings ratios (or "P/E's") above 18x, you may consider United States Steel Corporation (NYSE:X) as an attractive investment with its 9.5x P/E ratio. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

Recent times haven't been advantageous for United States Steel as its earnings have been falling quicker than most other companies. The P/E is probably low because investors think this poor earnings performance isn't going to improve at all. You'd much rather the company wasn't bleeding earnings if you still believe in the business. 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.

Keen to find out how analysts think United States Steel's future stacks up against the industry? In that case, our free report is a great place to start.

Does Growth Match The Low P/E?

The only time you'd be truly comfortable seeing a P/E as low as United States Steel's is when the company's growth is on track to lag the market.

Retrospectively, the last year delivered a frustrating 50% decrease to the company's bottom line. At least EPS has managed not to go completely backwards from three years ago in aggregate, thanks to the earlier period of growth. Therefore, it's fair to say that earnings growth has been inconsistent recently for the company.

Shifting to the future, estimates from the eight analysts covering the company suggest earnings growth is heading into negative territory, declining 2.0% per year over the next three years. With the market predicted to deliver 10% growth per year, that's a disappointing outcome.

With this information, we are not surprised that United States Steel 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 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.

As we suspected, our examination of United States Steel's analyst forecasts revealed that its outlook for shrinking earnings is contributing to its low P/E. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. Unless these conditions improve, they will continue to form a barrier for the share price around these levels.
