Financial funds ranked as the worst-performing group for the second week in a row.

Ten of the 19 largest declines among all U.S. funds exclusively focused on the financial industry during the week ending Thursday, Jan. 22. Investors fled financial stocks as fourth-quarter earnings reports revealed the magnitude of the damage to the major banking industry players.

Bank of America's

(BAC) - Get Report

fourth-quarter loss continued as details of billions in losses from its Merrill Lynch brokerage unit required another $20 billion infusion of U.S. Treasury capital and asset guarantees totaling $118 billion. Merrill's brokerage clients withdrew $10 billion from accounts in the fourth quarter, on top of $3 billion in the third quarter.

Merrill CEO John Thain departed last week after the firm paid billions in bonuses to employees on Dec. 29, just before the sale to Bank of America was completed, and he spent $1.2 million to redecorate his office. In the four trading days under review, fear that Bank of America may need even more capital drove the stock down another 31.4%. Additional government capital infusions risk "nationalization" as the government's share of ownership may exceed 50%.
