Earnings season kicks off next week, with America's biggest aluminum producer, Alcoa Inc. (NYSE: AA), announcing its second-quarter earnings results on July 9.

The story that is likely to emerge is one of slower profit growth. And looking further ahead, the news is likely to get worse, John Higgins, senior markets economist at Capital Economics, said in a note to clients. This is a key reason why we continue to expect the S&P 500 to end this year and next around the 1,350 mark.

The S&P 500 declined 6.44 points, or 0.5 percent, to close at 1,367.58 in Thursday's trading, with financial and energy stocks as the worst performers.

JPMorgan Chase & Co. (NYSE: JPM) has been in very hot water since the bank announced in May it had lost $2 billion related to credit derivatives. Some estimates now peg the loss to be as high as $9 billion.

JPMorgan Chase's second-quarter earnings release on July 13 will probably garner most attention as it plans disclose part of the total losses on the soured bet. Despite the loss, CEO Jamie Dimon has given many assurances that the bank is still on track to report solid second-quarter profits.

Wells Fargo & Co. (NYSE: WFC) will join JPMorgan Chase to release second-quarter earnings results after the market close on Friday.
