Currently, analysts expect fourth quarter earnings for S&P 500 companies to grow at a rate of 3.3 percent, according to the latest data from S&P Capital IQ. That’s a better growth rate than the previous quarter, but it’s considerably weaker than the 8.4 percent growth rate recorded in the same period last year.

Wells Fargo, the first major bank to report earnings, dropped even after the bank reported a 25 percent increase in fourth-quarter earnings. The bank’s stock fell 30 cents, or 0.8 percent, to $35.10.

JPMorgan Chase, Goldman Sachs, U.S. Bancorp, Citigroup and Bank of America are among banks and financial companies reporting earnings next week. Financial stocks were the best performing industry group in the S&P 500 last year, gaining 26 percent.

Boeing fell $1.93, or 2.5 percent, to $75.16 after the U.S. Federal Aviation Administration said it is launching a comprehensive review of the critical systems of Boeing’s 787, the aircraft maker’s newest and most technologically advanced plane, after a fire and a fuel leak earlier this week.

The yield on the 10-year Treasury note, which moves opposite to the security’s price, fell 4 basis points to 1.86 percent.
