The Amundi CAC 40 Daily (-1X) Inverse UCITS ETF Acc is a passively managed exchange-traded fund that provides inverse exposure to the CAC 40 Index, the benchmark for France's largest and most liquid blue-chip companies listed on Euronext Paris. Launched on June 9, 2008, in France, it tracks the CAC 40 Short GR EUR Index through synthetic replication using unfunded swaps, achieving a daily -1x leverage with rebalancing each business day. This structure means the fund's net asset value inversely mirrors the index's daily performance: rises in the CAC 40 lead to declines in the ETF, and vice versa, while reinvesting dividends (thesaurierend) without distributions. With a total expense ratio of 0.40% p.a. and assets under management around 100 million EUR, it employs derivatives to swap returns against a diversified international equity portfolio collateralized appropriately. The ETF plays a key role in hedging strategies, enabling investors to profit from or protect against downturns in the French equity market, particularly sectors like luxury goods, energy, and industrials dominated by holdings such as LVMH and TotalEnergies. Due to daily reset, performance over periods longer than one day may deviate from the simple inverse of the index.
