U.S. stocks struggled for direction late on Thursday morning, as investors remained cautious ahead of the kickoff of the annual gathering of central bankers at Jackson Hole, Wyoming.
Speeches from Federal Reserve Chair Janet Yellen and European Central Bank President Mario Draghi on Friday will be scrutinized for hints on the path of monetary policy, but neither of them are expected to give fresh guidance.
The central bankers` views will be a change from the past two weeks, when the stock market was roiled by concerns over geopolitics, mayhem in Washington, and President Donald Trump`s controversial comments.
Trump on Wednesday threatened to shut down the government if funds were not secured to build a Mexico border wall, comments that came as a late-September deadline looms for U.S. officials to raise the debt ceiling or risk a default.
"Political uncertainties remain ongoing, valuations are full and, technically, there is some signs of deterioration (in the stock market)," said Terry Sandven, chief equity strategist at U.S. Bank Wealth Management in Minneapolis.
"The backdrop seems favorable for equities to do what we`re seeing this morning and that is sideways trending."

Even economic data on the day was a mixed bag: while the number of Americans filing for unemployment benefits rose less than expected last week, home resales unexpectedly fell in July to their lowest monthly level of the year.
