A Rare Index Overhaul and a Tech Rut Collide for Vanguard’s All-World ETF

Broadcom's weak outlook, hot US inflation, and geopolitical jolts drive Vanguard FTSE All-World ETF down 3.6% as a historic SpaceX IPO forces an automatic purchase.

The Vanguard FTSE All-World UCITS ETF is navigating a treacherous June, buffeted by a trio of forces that rarely align so neatly. A brutal tech selloff, a historic mega-IPO that forces an automatic buy, and an index rebalancing stripped of its usual safety buffers are all hitting the fund within a matter of days. The share price recently slid to €158.36, extending a weekly loss of 3.62%.

The immediate trigger for the rout came from Broadcom, whose downbeat outlook for AI-chip revenue – just $16 billion, well below analyst expectations – sent its own shares crashing 14%. The shockwaves spread across the semiconductor complex, dragging down ASML, Applied Materials, and other industry bellwethers. That carnage, combined with a broader selloff in Nvidia and Micron, has disproportionately punished the Vanguard fund because these names are among its largest positions.

Compounding the tech pain was a surprisingly hot US inflation reading. The consumer price index rose 4.2% in May year-over-year, the highest in over three years, thanks mainly to surging petrol prices linked to the military standoff with Iran. Core inflation, stripping out energy, held at 2.9%, but markets now price in not just a steady Fed rate next week but a potential rate hike by December. That hawkish repricing hit growth stocks hardest.

Geopolitical jitters added another layer. After the downing of an American helicopter, US forces struck Iranian air-defence sites, sending investors fleeing from risky assets. On Wednesday, the ETF fell 1.01% to €159.22 before sliding further as the Broadcom news sank in.

Yet the most unusual pressure on the fund is structural. On June 12, SpaceX is set to debut on the Nasdaq in what would be the largest IPO in history, with a valuation of $1.75 trillion. Index provider FTSE Russell has granted the space company immediate admission to the All-World Index, forcing the Vanguard ETF to buy shares despite SpaceX’s minimal free float of just 3-5% and its multibillion-dollar losses. The S&P 500, by contrast, has refused inclusion.

The timing compounds the challenge. On June 20, FTSE Russell will conduct its quarterly rebalancing, and this time the usual 1% and 3% tolerance bands have been removed entirely. That means the portfolio will have to undergo far larger shifts than in normal quarters. Vanguard’s representative sampling approach – buying a subset of stocks rather than every single component – gives the fund managers some flexibility on timing. That cushion could prove vital when it comes to the forced SpaceX purchase.

Despite the near-term headwinds, the long-term trend remains intact. The ETF is still up roughly 8% year-to-date and trades a comfortable 24% above its 52-week low of €127.72. It hit a 52-week high of €165.24 only in early June. The next catalysts – US producer prices and the European Central Bank’s rate decision – arrive on Thursday and will provide the market’s next directional signal.
