Overview

The iShares Low Carbon Optimized MSCI ACWI ETF (CRBN) is an ESG-focused fund issued by iShares that currently holds an asset base of $1.14 billion. Trading at a price of $249.20, the fund carries an expense ratio of 0.2% and offers a dividend yield of 2.02%. Within the broader market of 458 tracked ETFs, CRBN holds an overall rank of #181, while it sits as the 11th fund in the specific ESG category monitored by ETFValuer. The fund has received an ETFValuer grade of C, reflecting a score of 63.7 out of 100. This ranking and grade suggest a moderate standing among peers, while the asset size indicates established investor adoption relative to smaller funds in the sector. The combination of a low expense ratio and a double-digit dividend yield positions the fund as a cost-conscious income option within its category.

Over the most recent trading day, the fund declined by 0.18%, following a weekly drop of 1.20% before recovering to a monthly gain of 0.63%. The three-month return accelerated to +3.07%, which continued into a six-month performance of +5.80% and a year-to-date increase of 8.12%. The one-year return reached +17.49%, showing a significant divergence from the shorter-term volatility observed earlier in the year. This upward trajectory extended further over the three-year horizon, where the fund posted a cumulative return of +67.50%. The data illustrates a pattern where short-term fluctuations gave way to sustained growth over longer holding periods. While the fund experienced a weekly decline, the longer-term metrics demonstrate a consistent recovery and expansion of value.

CRBN is classified with a Low volatility label and exhibits a beta of 0.99, indicating price movements that closely mirror the broader market. The fund's Sharpe ratio of 0.89 suggests a moderate risk-adjusted return profile relative to the risk taken. During market downturns, the fund experienced a maximum drawdown of -16.60%, which defines the peak-to-trough decline observed in its history. This combination of a beta near unity and a low volatility label implies the fund generally tracks market direction without amplifying swings. The Sharpe ratio and maximum drawdown figures together suggest that while the fund participates in market declines, it has historically delivered returns that compensate for the level of risk incurred. Investors should note that the fund's behavior aligns with a neutral market stance rather than aggressive outperformance or deep underperformance.

CRBN Liquidity, Domicile & Tax Treatment

Liquidity: Quoted bid/ask spread is 43.85% and average daily volume is 9K/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 $1.14B provides ample scale, supporting tight spreads and issuer commitment to keep the fund open.

Domicile & tax treatment: CRBN 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.
