Most European ETF investors are dangerously drunk on VWCE and IWDA record highs—and they don’t even realise the hangover risk. This week, both the Vanguard FTSE All-World UCITS ETF (VWCE) and the iShares Core MSCI World UCITS ETF (IWDA) smashed through new all-time highs. The euphoria is real. But before you toast your brokerage balance, ask yourself: are you sitting on a ticking time bomb of concentration risk?
Let’s get straight to the point: the stampede into these two so-called “global” ETFs is creating a dangerous illusion of diversification. The numbers look great—until you dig deeper. If you think buying VWCE or IWDA alone is a free lunch, you’ve forgotten that markets have a nasty habit of humbling the overconfident.
VWCE and IWDA: Record Highs, Record Complacency
On 6 June 2024, VWCE closed above €130 for the first time. Its YTD return? A scorching +14.2%. IWDA wasn’t far behind, crossing €81, with a blistering +13.4% YTD gain. If you bought either at the start of 2023, you’re up nearly 30%. By the numbers, these are dream returns for anyone who loves simple, low-cost passive investing.
But here’s the uncomfortable truth: the “global” in these ETFs is an illusion. Nearly 70% of IWDA is the US. VWCE—“All-World”—is 61% US-listed stocks. The top ten holdings? It’s the same parade: Apple, Microsoft, Nvidia, Amazon, Alphabet, Meta, etc. You’re not diversified. You’re just a Nasdaq tracker with a European accent.
VWCE and IWDA hit record highs on the back of a U.S. tech melt-up, not truly global growth.
Let’s be clear: if you’re celebrating your portfolio’s “worldwide” diversification, you’re mostly cheering for Silicon Valley and Wall Street. One bad earning season or rate shock in the U.S., and your “global” ETF suddenly looks very parochial.
Concentration Risk: Lessons from History and Today’s Reality
Don’t believe me? Let’s look at the data. In 2000, the MSCI World Index’s U.S. allocation hit a then-record 55%—right before the dot-com bubble burst. No other region came close. Fast forward to 2024: U.S. weighting is now 71% in the MSCI World, an all-time high. If you think this is safe, you haven’t read a single financial history book.
Remember Japan in 1989? The Nikkei made up nearly 44% of the MSCI World. By 2001, Japanese stocks lost over 60%—and global investors paid the price for mistaking “market cap weight” for “diversification.” Ask yourself: are you making the same mistake with VWCE and IWDA today?
In 2023 and 2024, more than 80% of the MSCI World’s returns came from just seven U.S. tech giants.
According to MSCI’s own data, these tech behemoths now account for an unprecedented share of global index returns. If you’re all-in on VWCE or IWDA, you’re betting the U.S. tech story never ends. That’s not diversification; it’s faith-based investing.
What European Investors Can—and Should—Do About It
Don’t get me wrong: I love cheap, index-tracking ETFs. But “set it and forget it” is not a risk management strategy. European investors need to wake up to the dangers of concentration. Here are three actionable moves:
- Rebalance Your Exposure: If your “global” ETF now makes up more than 70% of your equity allocation, it’s time to trim. Rebalancing isn’t market-timing; it’s risk control. Take profits and redeploy into underweight regions.
- Add True Diversifiers: Consider region-specific ETFs (e.g., MSCI EMU for Eurozone, MSCI Emerging Markets for Asia/Latam exposure). Don’t forget real assets or bonds. See Portfolio Diversification: The Only Free Lunch in Investing for why this matters.
- Review Your Risk Tolerance: If you’re up 30% in 18 months, your risk profile has likely drifted. Could you stomach a 25% drawdown if U.S. tech corrects? If not, act now—before the market does it for you.
Don’t just take my word for it. The 2022 mini-correction saw VWCE and IWDA fall by 18% and 17% respectively—wiping out two years of gains in six months. Imagine that with an even larger allocation to U.S. tech.
The Bottom Line
VWCE and IWDA record highs are not a free pass to complacency—if you ignore concentration risk, you’ll eventually pay the price.
To Be Fair: The Case for Staying the Course
Let’s steelman the counterargument. Why not just stick to VWCE or IWDA and ignore the noise?
First, the data is compelling: U.S. equities have outperformed every major market for over a decade. The S&P 500 trounced the Euro Stoxx 50 by 100%+ in total return terms since 2014. Passive global equity investors have, so far, been handsomely rewarded for “letting the weights run.”
Second, market cap weighting isn’t a bug—it’s a feature. If U.S. companies genuinely dominate global profits and innovation, why not own more of them? Attempting to “outsmart” the index is a mug’s game for most retail investors, and the cost of being underweight U.S. has been huge.
Third, diversification isn’t always about geographic labels. Many U.S. firms like Apple and Microsoft generate close to 60% of revenues abroad. In a sense, you get global economic exposure even through a U.S.-heavy ETF.
So yes, there’s a solid argument for sitting tight, ignoring short-term noise, and sticking with global cap-weighted funds. But only if you can stomach the ride when—inevitably—a major correction comes.
VWCE and IWDA: Highs Today, Pain Tomorrow?
If you’ve been lulled into thinking these record highs mean “all clear,” you’re playing with fire. History screams that concentration risk ends badly. The only free lunch in investing is real diversification—not owning more of whatever just hit ATHs.
Prediction: Within the next 18 months, we’ll see at least a 15% correction in VWCE and IWDA, triggered by a U.S. tech unwind or macro shock.
Don’t be the last one out when the party ends. Trim your “global” ETF exposure, diversify intentionally, and tighten your portfolio’s risk controls now. Record highs are for selling, not for sleeping.
