“Depends” means the category reflects an investor objective, not universal superiority.

Coverage, countries and sectors

Verified holdings, concentration, country and sector datasets are not currently connected. When available, each dataset will be labelled as official index data or Reference ETF holdings; listing domicile will not be presented as economic revenue exposure.

What this means in a portfolio

Holding both does not automatically create two independent portfolios. Overlapping companies and regions can make the combination an intentional tilt toward the exposure emphasised by MSCI ACWI IMI.

Common mistake

Assuming that adding MSCI ACWI IMI to MSCI ACWI automatically improves diversification, without checking overlap and concentration.

Historical comparison basis

Historical performance is represented using Grovcap-selected reference exchange-traded products. It is not the official index or spot return series. Fund or ETP returns can differ because of fees, taxes, tracking, cash positions, product structure and other implementation effects. Differences can reflect TER, tracking difference, withholding taxes, sampling, securities lending, cash drag, operating expenses, currency conversion and inception date.

Provider-reported net-asset-value total returns for the two reference products, in USD, as of 30 Jun 2026. Figures are taken from provider documents; Grovcap does not convert them into another currency and does not recompute them. Periods where the two products report different currencies, bases or reporting dates are withheld rather than aligned artificially.

Grovcap does not currently hold a daily net-asset-value time series for these products. Indexed performance charts, annualised volatility, maximum drawdown and return-per-risk therefore remain unavailable rather than being estimated from period returns.
