Hexagon Spin-Off and Index Revamp Converge on Vanguard All-World ETF as BlackRock Slashes Fees

The $66B Vanguard FTSE All-World UCITS ETF faces dual adjustments from Hexagon's Octave spin-off and FTSE Russell's semi-annual review, while rivals eye investors with lower fees.

Europe’s largest global equity tracker is facing a rare confluence of structural adjustments. The Vanguard FTSE All-World UCITS ETF must simultaneously digest a corporate spin-off from Swedish engineering group Hexagon and the semi-annual overhaul of its underlying benchmark, while a deep-pocketed rival attempts to lure cost-conscious investors with a thinner expense ratio.

The fund has been on a tear this year, hitting a fresh 52-week high of €161.54 on Friday, according to the latest trading data. That marks a gain of 0.54% from the prior session and pushes the one-year return past 25%. Since the start of 2025, the ETF has added roughly 10%.

Hexagon Spins Off Software Unit

The technical adjustment that has already begun revolves around Hexagon’s decision to hive off its software division into a separate entity called Octave Intelligence. Under the terms, holders of Hexagon shares will receive one Octave share for every ten Hexagon shares they own. Vanguard, which runs the ETF using physical replication, will mirror that distribution directly in the portfolio. The spun-off shares are scheduled to start trading on a US exchange from 1 June, and the index provider FTSE Russell will publish further details on 25 May.

FTSE Russell’s June Reshuffle

That spin-off is running parallel to a much broader index reset. FTSE Russell kicked off its semi-annual review on 20 May, using the 30 April ranking date as its reference. Preliminary lists of additions and deletions have been released, with the final composition to be confirmed on 8 June. All changes will become effective after the market close on 26 June, giving the ETF manager a tight window to rebalance without incurring excessive tracking error.

The reshuffling is particularly relevant for the fund’s emerging-market allocation. New listings and shifting market capitalisations in developing economies could alter the weighting of that segment once the dust settles.

Massive Footprint, Slim Tracking Error

Despite the dual adjustments, the ETF continues to operate with the precision that has made it a favourite among buy-and-hold investors. Net asset value stood at $185.18 on 20 May, recovering from a brief dip to $183.60 the previous day. Total assets across all share classes have swelled to $65.96bn, of which $41.76bn sits in the accumulating class that tracks the NAV figure.

The portfolio houses over 3,770 stocks spanning developed and emerging markets. Technology heavyweights dominate the top slots: Nvidia accounts for 4.7% of the fund, followed by Alphabet at 4.0%, Apple at 3.9%, Microsoft at 3.0%, Amazon at 2.5%, and Broadcom as another significant name. That tech concentration has rewarded investors handsomely over the past 12 months, contributing a 22.58% gain to the fund’s overall return.

Annual costs remain locked at 0.19% for the accumulating share class, while the tracking difference – the gap between the ETF’s performance and the index – has averaged a mere 0.05%, underscoring the precision of the replication.

The Price Challenger

That low-cost advantage is now under direct attack. In May, BlackRock launched a competing iShares FTSE All World ETF with an annual expense ratio of just 0.12%, undercutting Vanguard by 7 basis points. The newcomer, however, has a negligible asset base of roughly $19m, giving it little immediate weight to exert pressure. Yet the fee war underscores the growing commoditisation of global equity exposure.

For investors, the next milestone is 26 June, when the rebalanced index takes effect and the Octave shares will already be trading stateside. Until then, Vanguard’s flagship all-world fund must navigate both corporate and index mechanics – all while glancing over its shoulder at a fee-cutting rival.
