Over the most recent trading day, the fund posted a return of +1.15%, which accelerated to a weekly gain of +2.55% and a monthly increase of +2.59%. This momentum continued into the three-month period with a return of +9.13%, followed by a six-month gain of +15.07%. Year-to-date performance has been robust at +19.52%, while the one-year return stands at +25.18%. Extending the timeframe further, the three-year return reaches +57.20%, indicating a sustained upward trajectory over the longer term. The data shows a consistent pattern of positive returns across all measured horizons, with the annualized growth rate appearing to strengthen as the time period extends from one month to three years.
The fund carries a Low volatility label and a beta of 0.92, suggesting that its price movements have historically been less sensitive to broad market fluctuations. A Sharpe ratio of 1.50 indicates that the fund has generated a favorable amount of excess return per unit of risk taken over the measured period. Despite this efficient risk-adjusted performance, the fund experienced a maximum drawdown of -20.57% at some point in its history, representing the largest peak-to-trough decline recorded. This combination of a low beta and a Sharpe ratio above 1.0 implies that the fund has managed downside risk effectively relative to its returns, even though the maximum drawdown figure confirms that significant temporary losses are possible during market stress.

IWS Liquidity, Domicile & Tax Treatment
Liquidity: Quoted bid/ask spread is — and average daily volume is 450K/day. Tighter spreads and higher volume mean lower round-trip trading costs; this is a live-market snapshot and can widen during volatile sessions. AUM of $15.6B provides ample scale, supporting tight spreads and issuer commitment to keep the fund open.
Domicile & tax treatment: IWS is a US-domiciled, SEC-registered ('40 Act) exchange-traded fund. Dividends and capital gains distributions are reported to US investors on Form 1099-DIV, and the fund is not subject to the PFIC reporting or UCITS-specific rules that apply to Irish- or Luxembourg-domiciled funds. Non-US investors should note that US-domiciled ETFs are generally subject to 30% US withholding tax on dividends (unless reduced by treaty) and to US estate tax exposure on the position — Irish-domiciled UCITS ETFs tracking the same index often avoid both, which is why non-US residents frequently prefer the UCITS equivalent where one exists. This is general information, not tax advice — consult a tax professional for your situation.
