The banking giant reported quarterly revenue of 21.9 billion dollars, down two percent on a year-over-year basis.

JP Morgan Chase reported quarterly earnings per share of 1.76 dollars and net revenue of 26.2 billion dollars, beating market expectations. However, investors were concerned about the banking giant's 27-percent year-on-year decline in fixed income trading revenue.

Another Dow component Pfizer said Tuesday that it was thinking about selling or spinning off its consumer health-care business, which generates 3.4 billion dollars in annual sales.

On the economic front, the Labor Department said on Friday its Consumer Price Index for All Urban Consumers increased 0.5 percent in September on a seasonally adjusted basis. Over the last 12 months, the all items index rose 2.2 percent.

The consumer sentiment index, a survey of consumers by the University of Michigan, jumped to 101.1 in October, far exceeding economists' expectation of 95.

U.S. retail sales were lower than expected in September but recovered from the prior month's 0.2 percent slide.

The Commerce Department said on Friday the advance estimates of U.S. retail and food services sales for September 2017, adjusted for seasonal variation and holiday and trading-day differences but not for price changes, were 483.9 billion dollars, an increase of 1.6 percent from the previous month, and 4.4 percent above September 2016.

On Thursday, the Labor Department said its producer price index for final demand increased 0.4 percent last month after rising 0.2 percent in August. In the 12 months through September, the index rose 2.6 percent.
