Bank of America (BAC), the best performer in the Dow Jones Industrial Average for 2012, has more than doubled since the start of the year as the company rebuilds capital and investor confidence.

Bank of America climbed 1.4 percent to $11.15 at 10:33 a.m. in New York, bringing its advance for this year to 101 percent. The second-largest U.S. lender by assets has more than quadrupled since February 2009 when the stock sold for $2.53 during the credit crisis amid speculation it would be nationalized.
