The S&P 500 is down 11% in the first 12 trading days of 2009, exceeding last year’s 9.2 % drop, according to data compiled by Bloomberg going back to 1928. The decline helped erase more than two-thirds of a 24 percent rally since Nov. 20 as optimism that government spending would revive the economy evaporated.

‘Effectively Insolvent’

U.S. financial losses from the credit crisis may reach $3.6 trillion, according to New York University Professor Nouriel Roubini, who predicted last year’s economic and stock-market meltdowns.

“If that’s true, it means the U.S. banking system is effectively insolvent because it starts with a capital of $1.4 trillion,” Roubini said at a conference in Dubai today. “This is a systemic banking crisis.”
