On July 1st, Gelunhui | BlackRock, the world's largest asset management company, announced the launch of a "buffer" ETF, aiming to provide 100% downside protection for risk-averse investors seeking to enter the stock market. The so-called buffered or risk-managed ETF helps investors achieve maximum returns from their assets while providing downside protection during specific periods of time. Compared to traditional ETFs that track stock indices, "buffered" ETFs typically have lower redemption requests during volatile market conditions. Rachel Aguirre, the head of iShares Products in the United States at BlackRock, said that with record levels of cash on the sidelines, many investors are looking for tools to help them navigate market volatility before re-entering the market. The iShares Large Cap Max Buffer Jun ETF (MAXJ.Z) began trading on Monday with a net expense ratio (excluding exemptions and reimbursements) of 0.50%.
