Stocks fell significantly Friday at the end of a positive week on Wall Street, as a negative response to quarterly results from General Electric (GE) and Bank of America (BoA) gave investors a reason to retreat after the Dow industrials closed above 10,000 the previous two sessions. The U.S. dollar gained versus the euro and the yen. Light sweet crude oil for November delivery rose 95 cents to $78.53 a barrel on the New York Mercantile Exchange, one day after ending the previous session at the highest level in a year. Gold for December delivery rose 90 cents to $1,051.50 an ounce. The Dow Jones industrial average fell 67.03, or 0.7 percent, to 9.995.91. BoA reported a $2.2 billion third-quarter loss a consumer credit problems overshadowed strength in its wealth-management business. Its shares fell more than 4.5 percent. GE reported weaker quarterly profits that surpassed estimates, and its shares fell nearly 5 percent. IBM reported higher quarterly profits and lower revenue, and its shares fell 5 percent. The broader Standard & Poor's 500 index fell 8.88, or 0.8 percent, to 1,087.68. The technology-heavy Nasdaq composite index fell 16.49, or 0.8 percent, to 2,156.80. Google reported higher quarterly sales and profits, and its shares rose 3.8 percent. The New York Stock Exchange composite index fell 70.09 to 7,133.96. The American Stock Exchange composite index rose 0.40 to 1,860.61. And the Russell 2000 index fell 7.16 to 616.18.
