Among U.S. stocks with noteworthy moves:
-- Bank of America Corp. fell 14 cents, or 1.6 percent, to close at $8.83 after agreeing to pay $2.43 billion to settle a class-action lawsuit related to its acquisition of Merrill Lynch. The company was the best performer of the 30 stocks in the Dow during September, rising 10.5 percent. Home Depot was the best Dow stock for the third quarter.
-- Blackberry maker Research in Motion Ltd. jumped 36 cents, or 5 percent, to $7.50 after reporting a smaller-than-expected quarterly loss on Thursday night.
-- Shoemaker Nike fell $1.09, or 1.1 percent, to $94.91 after saying its first-quarter net income fell 12 percent because higher sales were offset by increased ad spending. The results were better than Wall Street had expected, but investors seemed more worried about the trail ahead for Nike rather than its performance in the last quarter.
-- McDonald's Corp. fell $1.52, or 1.6 percent, to $91.75 after Janney Capital Markets cut its rating and price target, saying difficult year-ago comparisons may pressure sales at stores open at least 13 months, which is a key revenue metric for retailers.
