The retreat from US stocks came during a week in which Democratic lawmakers moved to launch formal impeachment proceedings that could end with a vote to remove President Donald Trump from office and the White House released a summary of a telephone call between Trump and Ukraine's president that is at the center of the inquiry.
Last week's losses sent the year to date outflows from US stock funds to $91.1 billion as investors have shied away from domestic stocks despite a more than 15% rally in the benchmark S&P 500 index.
Investors continued to seek the perceived safety of bonds by sending slightly more than $6.9 billion into taxable and municipal debt funds. For the year-to-date, the category has garnered more than $319 billion in new inflows.
