Investors pulled $17.2 billion from U.S. stock funds in the week ended July 1, marking the first net outflow in three months and the fastest retreat from American equities since March, according to Bank of America citing EPFR Global data. BofA also said its sell signal remained active for a sixth consecutive week. The report pointed to rotation toward overseas markets, including a $1.9 billion inflow into Japanese equities, while doubts over artificial intelligence valuations weighed on technology shares and helped send the Philadelphia Semiconductor Index down 11% over two days.
