Shares of United Airlines tumble on sour outlook for 4Q profit because of rising fuel prices

Shares of United Airlines have tumbled after the carrier issued a gloomy outlook for fourth-quarter profit. And they took other airline stocks lower, too on Wednesday. United said after the market closed Tuesday that it earned $1.14 billion in the third quarter, which included much of the summer vacation-travel season. But investors are more focused on United's fourth-quarter forecast, which was far short of Wall Street expectations. On Wednesday, shares of United Airlines fell nearly 10%, the stock's worst one-day percentage loss since July of last year.
