Disappointing results from Bank of America and Citigroup tugged the stock market to its fifth straight loss Thursday.
Oil prices continued their slide, and U.S. government bonds jumped.
Weak revenue from trading pulled down Bank of America's profit 11 percent in the fourth quarter. The bank's earnings and revenue fell short of Wall Street's estimates. BofA's stock sank 84 cents, or 5 percent, to $15.20.
Discouraging news on the global economy and falling oil prices have rattled investors recently, even as the bull market for stocks closes in on its sixth anniversary.
