VU Vanguard S&P 500 UCITS Acc
VUAA - IE00BFMXXD54 100.00%
This “portfolio” is less a portfolio and more a personality test: do you believe the S&P 500 is life itself? With 100% parked in a single ETF, the structure is aggressively simple — like building a house entirely out of one very sturdy brick. It scores a “Balanced” risk label, but there’s nothing balanced about being all-in on one market and one asset class. Diversification score 2/5 feels generous; this is minimalism bordering on denial. The upside: it’s impossible to get lost in the holdings. The downside: if this one engine stalls, there is no second engine, no parachute, not even a seat cushion that floats.
Growth
Historically, this thing has ridden the US large-cap rocket nicely: €1,000 turning into €2,202 in just over six years, with a 13.38% CAGR. CAGR, by the way, is just your average speed over the whole trip, potholes included. Versus the US market benchmark, it’s basically a photocopy, and it comfortably beats the global market. The -33.68% max drawdown in early 2020 is the catch: a one-third drop in a month and nearly a year to crawl back. That’s the price of riding pure equity beta with no brakes. Past returns look heroic, but like yesterday’s weather, they don’t promise tomorrow’s sunshine.
Projection
The Monte Carlo projection is polite but blunt: future returns will not necessarily look like the last six years on steroids. Monte Carlo just runs thousands of random “what if” paths based on historical volatility — a financial version of rolling dice until your wrist hurts. Median outcome of €2,821 on €1,000 after 15 years is decent, but the range is the real story: from roughly halving in bad cases to hitting 7x in great ones. A 74.2% chance of a positive outcome means one in four universes still leaves you flat or worse. For a “balanced” label, those are very unbalanced potential endings.
Asset classes
- Stocks 100%
Asset class breakdown: 100% stocks, 0% everything else. This isn’t an allocation; it’s a declaration of faith that equities will solve all problems eventually. No bonds, no real assets, no cash buffer — just one long rollercoaster with no gentler rides anywhere in the park. Asset classes matter because different stuff misbehaves at different times; mixing them can smooth the ride. Here, the risk score of 4/7 understates how binary this really is. Either the equity engine keeps pulling, or the whole thing sulks together. There’s elegance in the purity, but also the stability of a one-legged chair.
Sectors
- Technology 34%
- Financials 12%
- Telecommunications 11%
- Consumer Discretionary 10%
- Health Care 9%
- Industrials 8%
- Consumer Staples 5%
- Energy 4%
- Utilities 3%
- Real Estate 2%
- Basic Materials 2%
Sector-wise, “Tech and friends” run the show: roughly a third in technology, double-digit chunks in financials and telecom, then everyone else fighting for scraps. This is what happens when you outsource everything to a cap-weighted index tilted toward whatever’s currently running hottest. Sector exposure matters because when one theme breaks — say growth, regulation, or rates — the damage clusters fast. Here, a tech-centric flavor means big sensitivity to innovation hype cycles and sentiment swings. It’s not absurdly skewed, but it definitely isn’t neutral either. The portfolio’s sector diet is more energy drink and less balanced meal.
Regions
- North America 99%
Geography: 99% North America. So this “global citizen” has essentially never left the US suburbs. For a European investor, it’s a full-on currency and country bet disguised as a diversified index. Geographic spread matters because different economies, politics, and currencies screw up in different ways and at different times. This portfolio basically says: “If the US stumbles long-term, I have no Plan B.” It’s worked beautifully in a decade where the US dominated, but that’s more lucky era than universal law. One region, one currency, one narrative — simple, yes, but anything but worldly.
Market capitalization
- Mega-cap 46%
- Large-cap 35%
- Mid-cap 18%
- Small-cap 1%
Market cap exposure is pure big-kid energy: 46% mega-cap, 35% large-cap, with mid-caps and small-caps tossed in like decorative parsley. This is the classic cap-weighted problem: the more popular and expensive something gets, the bigger slice it becomes automatically. Size matters because mega-caps can dominate index behavior, turning the “500 companies” story into “a dozen giants and some extras.” The tiny 1% in small caps is basically a rounding error. This portfolio behaves like a bet on the corporate aristocracy, with almost no role for smaller, scrappier firms that sometimes drive future growth.

- Top 10 total 36.59%
The look-through holdings just confirm the obvious: this isn’t the S&P 500, it’s the “NVIDIA–Apple–Microsoft plus entourage” index. NVIDIA at 7.6%, Apple at 6.7%, Microsoft at 4.9%, then the usual tech mega-cap suspects right behind. Because only top 10 ETF holdings are used, overlap is actually understated — reality is probably even more concentrated. Look-through analysis is just pulling off the ETF mask to see which companies really run the show. Here, a handful of names are effectively the main characters in the story, the other 490 sit in the background hoping their lines don’t get cut.
Risk contribution
-
Vanguard S&P 500 UCITS Acc
Weight: 100.00% 100.0%
Risk contribution is the most boring chart here because it tells a painfully obvious truth: one ETF, 100% weight, 100% of the risk. Risk contribution just shows which positions actually move the portfolio when markets swing. In this setup, there’s no mystery: if this fund jumps, everything jumps; if it tanks, everything tanks. No hidden diversifiers, no sneaky stabilizers, just a single dial marked “US equity market.” It’s extremely transparent, but also unforgiving. Any market stress that hits broad US stocks goes straight through the portfolio with no cushions or shock absorbers to dilute the impact.
Ongoing product costs
- Vanguard S&P 500 UCITS Acc 0.07%
- Weighted costs total (per year) 0.07%
Costs are the one area where this portfolio is almost suspiciously sensible. A 0.07% TER is about as close to free as mainstream investing gets — like paying loose change to borrow the entire US corporate machine. TER (total expense ratio) is simply the annual fee skimmed for running the fund. Here, the drag is microscopic, which means most of the damage or success will come from market moves, not fee leakage. It’s so cheap it feels accidental, as if someone sorted ETFs by fee and clicked the first one without overthinking. Honestly, fair play on this part.
