Reuters reports that data from Refinitiv Lipper showed that investment flows into U.S. equity funds jumped to a five-week high in the week ended March 17, buoyed by optimism over a massive stimulus package and on expectations that the Federal Reserve's monetary policy stance would remain dovish.

U.S. equity mutual funds pocketed a net inflow of $20.1 billion in the week, which marked a sixth straight week of net buying.

The inflows were led by U.S. small cap funds and mid-cap funds, seeing net purchases of $3.6 billion and $2.1 billion respectively. On the other hand, large-cap funds had an inflow of just $251 million.

Among sector funds, investors turned net buyers of tech funds this week, purchasing $832 million, as tech stocks appeared attractive at lower valuations after witnessing sharp selling in the prior weeks.
