Todd Rosenbluth, Head of Research at VettaFi, stated that due to ongoing interest rate uncertainty caused by the Federal Reserve's unclear future moves, investor demand for alternative assets like Collateralized Loan Obligations (CLOs) has increased, potentially making them the next major driver in the Exchange Traded Fund (ETF) industry. Rosenbluth also noted that while AAA-rated CLOs have a near-zero default rate, lower-rated CLOs carry higher default risk and market volatility under economic stress.
