Investor sentiments are turning lower after President Donald Trump said Tuesday, "We have a long way to go on tariffs with China."

"President Trump's renewed threat of more tariffs on Chinese goods has investors bracing for weak trading in the Asian session today, tracking the negative sentiment in the U.S. overnight," ING economists Nicholas Mapa and Prakash Sakpal said in their report.

The S&P 500 fell 10.26 points, or 0.3%, to 3,004.04. That marks the first decline in the benchmark index after five days of gains.

The latest round of US corporate financial reports ramps up this week and investors have low expectations. Wall Street is forecasting a 2.6% drop in profit for S&P 500 companies. It is set to be the first back-to-back quarterly decline in three years.

Also highly anticipated is the Federal Reserve meeting at the end of the month. Wall Street expects the central bank to raise interest rates to help secure U.S. economic growth threatened by a trade war with China.
