According to LSEG data, investors disposed of a net $11.73 billion worth of U.S. equity funds during the week, registering a fourth weekly outflow in five weeks.

A lackluster U.S. manufacturing reporton Tuesday reignited investor concerns about economic growth, ahead of the crucial non-farm payrolls report due at 8:30 a.m. ET (1230 GMT).

The technology sector faced about $879 million worth of net sales, the biggest weekly outflow in six weeks. Investors, meanwhile, bought financial sector funds for the fourth successive week, worth about $418 million.

Investors, meanwhile, funneled a net $45.81 billion worth of investments into the safety of U.S. money market funds, extending their purchases into a fifth consecutive week.

U.S. bond funds, meanwhile, attracted inflows for the 14th week in a row, recorded at $2.23 billion on a net basis.
