JP Morgan predicted that the U.S. stocks have a positive outlook next year, the target of S&P 500 Index for 2015 was set at 2,250, suggesting potential upside of nearly 9%; and index constituents' 2015 earnings growth was predicted to be 8%, representing an estimated comprehensive P/E of 17.7x. 

Moreover, the broker also anticipated that the Federal Reserve might start to raise interest rates in June 2015 and the market will reflect the liquidity factors, so the volatility of the market next year will be greater than the first half and the fourth quarter of this year.
