The Greenbrier Companies, Inc. (NYSE:GBX) shares have had a really impressive month, gaining 27% after a shaky period beforehand. Taking a wider view, although not as strong as the last month, the full year gain of 13% is also fairly reasonable.
In spite of the firm bounce in price, Greenbrier Companies may still be sending very bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 7.8x, since almost half of all companies in the United States have P/E ratios greater than 19x and even P/E's higher than 34x 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 limited.
Greenbrier Companies certainly has been doing a good job lately as it's been growing earnings more than most other companies. One possibility is that the P/E is low because investors think this strong earnings performance might be less impressive moving forward. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.
