Strong second quarter earnings reports helped offset weakness in last month's jobs report and China's retaliatory tariffs. Non-farm payrolls came in at just 157,000 in July, which was less than the 195,000 consensus forecast. China also responded to President Trump's $200 billion in new tariffs on Chinese products with $60 billion in tariffs on U.S. products – which is actually an escalation on a relative basis since China buys less from the U.S. than the U.S. buys from China.

Second quarter earnings have been very strong, with about 80% of S&P 500 companies reporting positive earnings surprises and nearly three-quarters reporting positive sales surprises. However, President Trump's trade war could take a toll starting next quarter, with about three times as many companies issuing negative earnings guidance versus positive earnings guidance. This is particularly problematic since stock valuations, as measured by P/E ratios, stand at 16.5x, above both the five- and 10-year averages, according to FactSet's Earnings Insights.

Next week, traders will be keeping a close eye on several key economic indicators, including jobless claims on Aug. 9 and the consumer price index on Aug. 10. The market will also be keeping an eye out for President Trump's response to the new Chinese tariffs, which could mark a further escalation in what's quickly becoming a costly trade war for the two largest economies in the world. (See also: Trump Trade War Is a Buying Opportunity: Fundstrat.)
