JPMorgan Chase and Bank of America are among the top stocks in the Dow Jones industrial average on Friday. The gains come even after Moody's cut the credit ratings on 15 large banks after the market closed Thursday.
The Dow is up 56 points to 12,630 an hour after the opening bell. That's a rise of 0.4 percent.
Moody's had been warning that it would make the move since earlier this year. Analysts at KBW said the step by Moody's removes uncertainty had been hanging over the banks for months.
The KBW analysts called Morgan Stanley "the clear winner" and said JPMorgan took second place. Some analysts expected the rating agency to make deeper cuts to their credit scores.
Morgan Stanley rose 2.6 percent in early trading, gaining 35 cents to $14.32.
JPMorgan Chase jumped 2.5 percent, adding 88 cents to $36.38. Bank of America rose 1 percent, or 8 cents, to $7.89.
The Standard & Poor's 500 index rose 6 points to 1,331 and the Nasdaq composite index climbed 16 points to 2,874. The early gains turned the Nasdaq positive for the week. The other two major indexes are still on course to end the week lower.
Bank stocks were the strongest industry group among the 10 tracked by the S&P 500 index. Only two sectors fell, industrial and materials companies.
European and Asian stocks fell again on Friday.
