U.S. Steel (X - option chain) stock is trading lower today after the company reported a fourth-quarter loss of $267 million, or $1.86 per share, on revenue of $3.35 billion. Analysts were expecting a loss of $1.44 per share on revenue of $3.09 billion. The company also forecast a first-quarter loss in line with fourth quarter results, whereas analysts are forecasting a loss of 44 cents per share. If you think this stock won't be rising too far in the coming months, then it could be a good time to look at a bearish hedged play on GE.

This morning, X opened at $52.66. So far today the stock has hit a high of $53.40 and a low of $50.37. As of 12:00, X is trading at $51.11, down $5.12 (-9.1%). The chart for X looks bearish and S&P gives X a negative 2 STARS (out of 5) sell ranking.

Not-for-squeamish U.S. Steel (NYSE: X) is rising on schedule, despite a recent pull-back, which is why I'm reiterating my Buy rating for the company, first recommended on April 15, 2009, at a price of $27.61. If you bought X in April, you're up about 28%.

The rationale for owning X's shares remains the same. U.S. Steel will likely be a survivor in the consolidating global steel sector with sufficient scale to either produce raw materials and acquire raw material assets.

It was good news bad news for the steel industry Tuesday. AK Steel Holding Corp. (NYSE: AKS) and United States Steel Corp. (NYSE: X) both reported better-than-expected third-quarter results. But for U.S. Steel, it was the third straight quarterly loss as the economic downturn continued to drag down demand.

For the three months that ended in September, U.S. Steel said it lost $303 million, or $2.11 per share. That compares with a profit of $919 million, or $7.79 per share, in the same period of last year. Revenue for the quarter fell 61% to $2.82 billion. Analysts surveyed by Thomson Reuters had expected a loss of $2.87 per share on revenue of $2.72 billion.
