Description

Amundi CAC 40 Daily (-2x) Inverse UCITS ETF Acc tracks the issuer-declared index: CAC 40 Double Short Gross Return. The declared annual cost (TER) is 0.60%, plus 0.00% in transaction costs estimated by the issuer in the KID. Replication is synthetic replication (swap based); income is accumulated and reinvested in the fund. The fund has assets of about 190 million euro, was launched on 19 April 2018 and is domiciled in France.

The fund’s objective — in the issuer’s words

The Fund is a passively managed index-based UCITS. The Fund's objective is to be inversely exposed with a daily rebalancing to the French stock market by replicating, both upwards and downwards, the performance of the CAC 40 Double Short GR strategy index (gross dividends reinvested) (the "Benchmark"), denominated in euro (EUR) and which is a short selling strategy (with a daily -2x leverage effect), with daily rebalancing, on the CAC 40® index (gross dividends reinvested) (the "Parent Index"), the main French stock exchange index, while minimising the tracking error between the Fund's performance and that of the Benchmark. The expected level of the Tracking Error under normal market conditions is indicated in the Fund prospectus. Over a period of one working day, any appreciation in the value of the Parent Index shall lead to stronger depreciation of the net asset value of the Fund, meaning that investors will therefore not benefit from the appreciation in the value of the Parent Index. However, for a period greater than one working day, due to the daily leverage readjustment conducted in the Benchmark, the performance of the Fund will not be equal to double the inverse of the performance of the Parent Index and may even follow an identical (i.e. not inverse) development. The Euronext website (www.euronext.com) provides more detailed information about Euronext indices. The Fund aims to achieve its objective by means of indirect replication, namely by entering into one or more OTC swaps (forward financial instruments, "FFIs"). The Fund may invest in a diversified portfolio of international shares whose performance will be exchanged against that of the Benchmark through FFIs. The updated composition of the portfolio of securities held by the Fund is mentioned on the website amundietf.com. In addition, the indicative net asset value appears on the Fund's Reuters and Bloomberg pages and may also be mentioned on the Fund's stock exchange websites. The Fund is eligible for the French Plan d'Epargne en Actions (PEA) and, consequently, invests a minimum of 75% of its assets in the shares of European Union countries.

From month-end NAVs, over the fund’s full history, on the series shown in the chart (dividends reinvested where declared). Deeper colour = larger move.
Source: Amundi. Issuer-declared historical series; inflation: Eurostat and national statistical institutes, latest available July 2026 — for later days the index stays at the last published value (institutes publish with a few weeks’ lag). The «adjusted for inflation» view expresses value in today’s purchasing power for the selected country; volatility always stays nominal, as elsewhere on the site (deflating it would add artificial swings caused by the monthly cadence of the price index). Past performance is not indicative of future results: these are facts, not a recommendation.

Tracking difference — issuer-declared

How much the fund returned above (+) or below (−) its index, year by year. It measures the actual deviation: the combined effect of costs (TER and transaction), securities-lending revenue and replication optimisations — which is why it can beat the TER. Tracking difference was positive in 2 of the last 10 calendar years: a past observation, not an indication of future outperformance.
