Investors in US stock funds held off from moving much of their cash in the latest week, amid growing tensions in Washington and after a Federal Reserve-driven rally.

Last week had the smallest change in US stock fund assets since the week ended May 29, the week after the Fed threw markets for a loop with discussions of pulling back on stimulus, according to Lipper. Overall, investors withdrew $492 million from US equity mutual funds and ETFs in the week ended September 25.
