Stocks turned mixed by mid-morning Friday after business activity in Chicago rebounded and consumer sentiment improved.

The S&P 500 was down 0.11%, the Dow Jones Industrial Average fell 0.03%, and the Nasdaq rose 0.1%.

Chicago PMI bounced back into positive territory in October, climbing to a reading of 56.2 from 48.7 in September. The reading was its highest since January, boosted by gains in new orders and production. 

Consumer sentiment moved higher to a reading of 90 in October from 87.2 in September, according to the University of Michigan, as global market volatility eased and gasoline prices remained low. However, the index wasn't as high as a preliminary reading of 92.1. 

Consumer spending rose in the U.S. in September at the slowest pace this year as consumers spent less on gasoline. Personal spending increased 0.1% over the month, according to the Commerce Department, half the increase economists had expected. Consumers have also become more conservative in recent weeks as the global market looked to be on shakier ground and the U.S. labor market showed signs of weakness. 

U.S. equities are on track to close out with the best monthly gain in four years. Benchmark indexes have rallied in October as China and the European Central Bank committed to do whatever it takes to reinvigorate flagging growth. Markets in the U.S. rallied on Wednesday after the Federal Reserve held rates steady. However, a potential December rate hike was left in play. Investors had hoped the Fed would provide further clarification on how likely a rate hike this year might be.
