It is a global equity ETF that tracks the MSCI ACWI index. It holds large- and mid-cap stocks across developed and emerging markets on a market-cap-weighted basis, delivering global diversification through a single ticker.

It suits long-term core investors who want to diversify across the entire global equity market at once, rather than limiting exposure to the US.

It is a passive (index-tracking) ETF managed by BlackRock (iShares).

The fund holds the constituents of the MSCI ACWI index in proportion to their market capitalization, tracking the performance of global equity markets across developed and emerging economies. Changes to the index composition are applied periodically at the discretion of the index provider. The US carries a large weight, but exposure extends across the global market.

• Diversifies across developed and emerging markets at once with a single ticker
• Widely used as a global core holding

Assets under management (AUM) stand at $33.0B, and the total expense ratio is 0.32% per year.

What sets it apart from similar global ETFs focused on developed markets is its inclusion of emerging markets, and the difference in fees is a factor to consider when comparing.

Over the long term, it has followed an upward trend in line with global economic growth, while short-term moves are shaped by the US market as well as the global economy, exchange rates, and interest rate conditions. The trend can show volatility depending on the period.

Fund flows have been fairly steady thanks to demand for globally diversified core holdings, though the direction of flows tends to shift with risk appetite and sentiment toward emerging markets. Inflows and outflows alternate depending on market conditions.

Its strength is delivering worldwide diversification through a single ticker, while its drawback is that its fee is somewhat higher than some similar ETFs.

In the table, VEA, IEFA, and EFA are ETFs focused on developed markets outside the US, while VXUS is a broad ETF with exposure to developed and emerging markets outside the US. If you want the same worldwide exposure, you can consider VT, a lower-fee direct substitute that also includes the US. To adjust your emerging market weighting separately, you can also consider IEMG.

Here are the points to review before investing in ACWI. It is a core holding that delivers global diversification through a single ticker, but costs, regional weights such as the US and emerging markets, and currency exposure are items to check before buying.

Concentration in US large caps and currency fluctuations are the main drivers of short-term volatility, and the emerging market weight can be an additional source of volatility. During market crashes, short-term losses can be significant even with global diversification.

It is a standard choice as a global core holding with exposure to worldwide equities through a single ticker. If cost is your priority, VT can be an alternative, and if you want diversification excluding the US, VXUS or IEFA can serve that purpose.
