2. JP Morgan kicks off banks’ Q3 earnings season

Though markets traditionally consider Alcoa’s earnings, out last Tuesday, to be the unofficial start of the third quarter (Q3) reporting season, JP Morgan has the double duty of being the first major financial institution and the first component of the Dow Jones to release earnings.

The world’s largest bank smashed estimates in the second quarter which may imply that the market has set the bar high for the July to September period.

Experts currently expect JP Morgan to report earnings-per-share (EPS) of $1.39, compared to $1.68 in the same period last year, while revenue is expected to increase to $23.8 billion from last year’s $23.5 billion.

After JP Morgan’s earnings release scheduled for 10:45GMT, both Wells Fargo and Citigroup will step up to the plate at 12:00GMT.

Chinese consumer prices rose 1.9% year on year in September, the strongest increase in five years. Inflation is up thanks to a weaker yuan and higher prices of commodities, including oil. Producer prices also grew in September, the first increase in almost five years.

The positive reading eased concerns about China's economy after disappointing export data Thursday.
