Investors noted that iShares ESG Aware MSCI USA ETF (ESGU)lost $4 billion in one day, while the iShares MSCI USA Quality Factor ETF (QUAL) gained $4.8 billion on the same day. ESG-focused ETFs invest in companies that have a strong environmental, social, and governance (ESG) track record. Quality factor ETFs invest in companies that have a strong track record of profitability, quality, and low volatility. The fund experienced redemptions of $1.6 billion over the year that ended February 28, a significant decline from the fund's recent inflows. Market experts suggest that the high trading volume may signal a move away from the ETF as part of a larger strategic shift.
