Amundi Smart Overnight Return UCITS ETF Acc is an actively managed exchange-traded fund designed to closely replicate the performance of the euro short-term rate (€STR) compounded index, targeting short-term returns with extremely low volatility. Launched in March 2015 and domiciled in Luxembourg, it serves as a low-risk option for investors seeking capital preservation and modest yields akin to money market instruments, outperforming traditional savings while minimizing exposure to equity market fluctuations. The ETF employs indirect replication through a diversified portfolio of high-quality, very short-term debt securities from governments and corporations, alongside financial derivatives such as total return swaps and currency hedges to track the benchmark accurately and manage risks. With a total expense ratio of 0.10% per annum and an accumulating distribution policy, it reinvests income to compound value over its recommended short holding period of about three months. Classified in the lowest risk category, Amundi Smart Overnight Return UCITS ETF Acc plays a key role in cash management strategies, offering liquidity and stability in fixed-income segments of the financial markets.
