Bank of America insists it has more than enough capital, but the market clearly disagrees. The stock was pounded again today in an up market, dropping 8% to $6.42. One analyst, Layla Peruzzi of Jefferies, thinks that Bank of America needs to raise an eye-popping $40-$50 billion. Assuming most of this capital-raise came in the form of equity, the dilution would be severe: The bank's market capitalization is now only $65 billion.
