Trade talk and politics could hang over the market in the coming week, even with a blast of earnings news providing a bright spot.
Earnings growth for the first quarter is expected to be up about 18.5 percent, according to Thomson Reuters. The first three major banks, J.P. Morgan Chase, Citigroup and Wells Fargo, to report earnings Friday all beat expectations.
But their stocks traded lower Friday on disappointment that their earnings gains were not more broad-based. Bank of America reports Monday and there is a slew of other financial names, including US Bancorp and KeyCorp reporting.
"If this is any indication of how earnings season is going to go, it's time to look closely at your portfolio. Even if you deliver good earnings, it doesn't mean the market will reward you," said Peter Boockvar, chief investment strategist at Bleakley Financial Group.
Stocks were higher for the week, with the S&P 500 up nearly 2 percent at 2,656. But Friday was weak, and traders were concerned about the possibility that the U.S. could bomb Syria over the weekend or that President Donald Trump would fire Deputy Attorney General Rod Rosenstein.
