“A lot of people are expecting a beat on earnings growth for the quarter,” said Robert Pavlik, chief investment strategist at SlateStone Wealth. “But I think there are some questions about growth moving forward.”
So far, just 5.7 percent of S&P 500 companies have reported second-quarter results. Overall, 86 percent of those companies have posted better-than-expected earnings, with profits growing by 20.1 percent, FactSet data shows.
Stocks posted strong gains last week despite increasing trade tensions, with the major indexes rising . Last week, the Trump administration unveiled a list Chinese goods it will potentially target with a 10 percent tariff. The list added up to $200 billion worth of items. The announcement came just days after both nations imposed $34 billion worth of tariffs on each other.
"Last week, we had some strength in the face of trade concerns and it seems like we're taking a break after that," said Ryan Detrick, senior market strategist at LPL Financial. "A lot of this is priced in, but we need some sort of positive resolution" for the market to move back to all-time highs.
