In contrast, there was an outflow of $47.3 billion from cash funds, the largest in four months, BofA said.

It noted that an inflow into global stocks over the past five months at $602 billion exceeds the inflow in the prior 12 years of $452 billion.

BofA also pointed to strong flows into investment-grade bonds, emerging market equities. Tech sector inflows resumed too, with $1.6 billion received, the bank added.
