The 3-month performance slowed to +0.94%, indicating a deceleration in momentum during that specific quarter. However, the trend accelerated significantly over the longer term, with the 6-month return reaching +8.78% and the year-to-date figure settling at +8.14%. Annual performance showed further strength with a 1-year return of +11.10%, while the 3-year return accumulated to +51.38%. This pattern illustrates a divergence where short-term gains were modest compared to the substantial growth recorded over the three-year period.
IDU is classified with a Low volatility label and exhibits a beta of 0.48, suggesting it moves less than the broader market. The fund generated a Sharpe ratio of 0.43, reflecting the risk-adjusted return relative to its volatility. During market downturns, the fund experienced a maximum drawdown of -16.57%. This combination of a low beta and low volatility label implies the fund generally experiences smaller price swings than the average equity. The Sharpe ratio of 0.43 indicates that the returns achieved were moderate relative to the risk taken, while the maximum drawdown figure quantifies the peak decline from a high point during the tracked period.

IDU Liquidity, Domicile & Tax Treatment
Liquidity: Quoted bid/ask spread is 5.96% and average daily volume is 146K/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 $1.39B provides ample scale, supporting tight spreads and issuer commitment to keep the fund open.
Domicile & tax treatment: IDU 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.
