USA TODAY: Shares of the Mexican-food chain became a hot tamale Thursday on Wall Street when they more than doubled in their first day of trading, gaining $22 to $44.
The stock’s smoking first day says as much about initial public offerings as burritos. It’s the first time shares of a U.S. company have doubled in their first day since November 2000, when computer-chip maker Transmeta gained 115%, Thomson Financial says.
