Description

Amundi MSCI USA Mega Cap UCITS ETF Acc tracks the issuer-declared index: MSCI USA Mega Cap Select Net USD Index. The declared annual cost (TER) is 0.15%, plus 0.02% in transaction costs estimated by the issuer in the KID. Replication is direct physical replication; income is accumulated and reinvested in the fund. The fund has assets of about 9 million euro, was launched on 12 November 2024 and is domiciled in Ireland.

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

The Sub-Fund is passively managed. The objective of the Sub-Fund is to track the performance of the index “MSCI USA Mega Cap Select Index” (the “Index”). The anticipated level of tracking error, under normal market conditions, is indicated in the prospectus of the Sub-Fund. The Index is an equity index based on the "MSCI USA Index" (the “Parent Index”), representative of the large and mid-cap stocks of the US equity market. . The Index aims to represent the performance of the largest securities of the Parent Index based on the market capitalization. More information about the composition of the Index and its operating rules are available in the Prospectus and at: www.msci.com. The Index value is available via Bloomberg (MXUSMENU). The Index is a net total return index, meaning that dividends net of tax paid by the index constituents are included in the Index return. The exposure to the Index will be achieved through a Direct Replication, mainly by making direct investments in transferable securities and/or other eligible assets representing the Index constituents in a proportion extremely close to their proportion in the Index. The Investment Manager will be able to use derivatives in order to deal with inflows and outflows and which relate to the Index or constituents of the Index for investment and/or efficient portfolio management. In order to generate additional income to offset its costs, the Sub-Fund may also enter into securities lending operations.

Drawdown — distance from previous peak

This isn’t the return: it shows how far the fund is below its previous peak. 0% = you’re at the peak; below zero = how much you’re down and haven’t recovered yet.

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 — fund vs index

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.

Windows longer than the available price history cannot be computed and are not shown: they will appear on their own as time passes. Computed from the daily NAV series, always in nominal terms. Sharpe and Sortino use the ECB main refinancing rate averaged over the period (last year: 2.21%), weighted by days in force, as the risk-free rate. Same formulas as our public methodology: sample standard deviation annualised over 252 days; Sortino with downside deviation. Past performance is not indicative of future results.
