Weak trading hits JPMorgan, profit falls in three core businesse

``JPMorgan Chase & Co., the biggest U.S. bank by assets, reported a 6.4 percent decline in revenue and profit declines in three of its four main businesses, underscoring how weak trading markets and low interest rates have hurt banks in recent months. Like other banks, JPMorgan has been struggling to increase revenue in the face of weak demand for loans and low interest rates, which have been stuck near zero for overnight funds since December 2008.''
