The fund’s objective — in the issuer’s words(the issuer publishes the KID in Italian)

Il Fondo è a gestione passiva e mira a replicare la performance dell'indice MSCI World Mega Cap 18% Capped Specified Index (l'«Indice»).
Keep reading the KID section ▾
L'Indice è concepito per misurare la performance delle società a più alta capitalizzazione quotate sui mercati di tutto il mondo.
Il Fondo cercherà di detenere tutte le azioni dell'Indice nella medesima percentuale, in modo tale che il portafoglio del Fondo sarà sostanzialmente un'immagine quasi speculare dell'Indice. Nel cercare di realizzare il suo obiettivo d'investimento di replicare l'andamento dell'Indice, in circostanze eccezionali il Fondo può anche detenere titoli che non sono inclusi nell'Indice, tra cui, ad esempio, titoli per i quali è stato annunciato o è previsto che verranno presto inclusi nell'Indice. Per ridurre il rischio o i costi o per generare capitale o reddito aggiuntivo, il Fondo può utilizzare strumenti derivati. L'uso di strumenti derivati può moltiplicare i guadagni o le perdite del Fondo relativi a un determinato investimento o ai suoi investimenti in generale. Nel Fondo possono essere disponibili anche classi di quote con copertura valutaria. Il Fondo può effettuare operazioni di prestito titoli. I rischi di sostenibilità non sono sistematicamente integrati in quanto non sono considerati parte del processo di selezione dell'Indice. Il rendimento del fondo dipende principalmente dalla performance dell'indice replicato. I proventi del Fondo non vengono versati, bensì reinvestiti.
Investitore al dettagliocui si intende commercializzare il prodotto Questo fondo è adatto a investitori al dettaglio in possesso di nozioni basilari in campo finanziario che sono in grado di sopportare una possibile perdita sull'importo investito. Il fondo mira ad aumentare il valore dell'investimento, garantendo l'accesso quotidiano al capitale in normali condizioni di mercato. Investendo in questo fondo, gli investitori possono soddisfare esigenze di investimento a medio termine. Il fondo può essere acquistato dai segmenti di clienti target senza alcuna restrizione in termini di canale o piattaforma di distribuzione.

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: UBS. 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.

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. Figures in EUR — series converted day by day at ECB reference rates; the table follows the currency selected in the chart.
