Assets invested in U.S.-listed exchange-traded funds and products rose to more than $2.2 trillion in April, a record, ETFGI reported Wednesday.
At the end of April, the U.S. sector had 1,884 ETFs/ETPs from 97 providers listed on three exchanges.
ETFs/ETPs listed globally on 65 exchanges in 51 countries also set a record last month, with invested assets slightly exceeding $3.1 trillion.
"Following a strong market performance in March, the S&P 500 index was up just 0.39% in April," ETFGI managing partner Deborah Fuhr noted in a statement.
Developed markets ex-U.S. were up 3.2%, while emerging markets ended up 1.1% and the S&P GSCI commodity index was up 10.1%.
"There is still a significant amount of uncertainty in the markets due to the upcoming Brexit vote, the U.S. election, the efficacy and future of QE programs around the world." Fuhr said.
In April, U.S.-listed ETFs/ETPs had net inflows of $11.2 billion. Equity funds accounted for the largest net inflows, with $8.2 billion, followed by fixed income funds with $2.8 billion.
