Weak trading hits JPMorgan, profit falls in three core businesses

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. Trading was particularly volatile during the quarter as worries about the impact of an economic slowdown in China roiled financial markets, discouraging investors from making big bets and muddying the outlook for U.S. interest rates.
