This portfolio is built from three equity ETFs only: a broad US index core holding at 70%, a wide European index at 20%, and a dedicated semiconductor ETF at 10%. So it is fully invested in stocks, with no bonds or cash buffers in the mix. The large position in the US ETF makes it the main driver of overall behaviour, while the semiconductor slice introduces a focused theme on top. This structure is simple and transparent, which makes it easier to understand how market moves feed into total returns. At the same time, relying on only three positions naturally concentrates both performance and risk into a handful of building blocks.
Over the period from late 2020 to mid‑2026, €1,000 in this portfolio would have grown to about €2,499. That works out to a compound annual growth rate (CAGR) of 18.15%, meaning the value increased by roughly that percentage per year on average. This outpaced both the US market benchmark at 16.05% and the global market at 13.37%. The maximum drawdown, or biggest peak‑to‑trough drop, was about ‑23%, similar to the US benchmark. The portfolio recovered from that fall in around six months. This profile shows historically strong growth with equity‑like swings, especially concentrated into about 34 very good days.
The forward projection uses a Monte Carlo simulation, which is like running the portfolio’s past behaviour through a thousand “what‑if” scenarios to see a range of possible futures. Based on historical returns and volatility, the median outcome turns €1,000 into about €2,951 after 15 years, with most simulations falling between roughly €1,949 and €4,298. The model also shows an 85.4% chance of finishing above the starting value, with an average annualized return across simulations of 8.36%. These numbers are not forecasts or promises; they simply illustrate what could happen if future markets behaved in ways statistically similar to the past, which they rarely do exactly.
All of this portfolio is in equities, so the asset class breakdown is 100% stocks and 0% bonds, cash, or alternatives. Asset classes are broad categories like stocks, bonds, and real estate that tend to react differently to economic events. A single‑asset‑class portfolio like this usually offers higher long‑term growth potential but can also experience deeper and more frequent swings along the way. Compared with many mixed stock‑and‑bond allocations, this structure leans clearly toward growth over stability. The diversification here comes from spreading across many companies and regions within equities, rather than from combining different asset classes with distinct risk profiles.
Sector‑wise, the portfolio is clearly tilted toward technology at 37%, while financials, industrials, health care, and consumer areas each make up smaller slices. The dedicated semiconductor ETF increases this tech exposure beyond what broad‑market indices typically hold, which is why technology stands out compared with many standard benchmarks. Sector exposure matters because different parts of the economy can move very differently during interest‑rate changes, recessions, or booms. A tech‑heavy profile like this often benefits strongly when innovation and growth stocks are in favour, but can feel sharper downturns when markets rotate toward more defensive or value‑oriented areas.
Geographically, around 78% of the portfolio sits in North America and 21% in developed Europe, with only a small fraction in developed Asia. In practice, that means results are heavily influenced by US and European economic conditions, corporate earnings, and central bank decisions. Compared with a global market index, which usually includes more from Asia and emerging markets, this allocation is more regionally focused. Geographic spread can help when different economies are at different points in the cycle. Here, diversification is reasonable across two major developed regions, but less exposed to growth or risk in other parts of the world.
By market capitalization, or company size, this portfolio leans strongly to the largest firms: 46% in mega‑caps, 36% in large‑caps, 16% in mid‑caps, and only about 1% in small‑caps. Market cap matters because bigger firms often have more stable earnings, broader business lines, and more analyst coverage, while smaller firms tend to be more volatile but sometimes faster‑growing. This structure is very close to how major equity indices are built, so it aligns well with common benchmarks. The main implication is that portfolio behaviour will be dominated by the world’s biggest companies, with relatively limited exposure to smaller, potentially more volatile names.
Looking through the ETFs, the top underlying holdings are some of the largest global tech and growth companies, with NVIDIA, Apple, Microsoft, Broadcom, Amazon, Alphabet, ASML, Meta, and Tesla all featuring prominently. NVIDIA alone accounts for about 6.48% of the total portfolio, thanks partly to the semiconductor ETF. Several names appear across multiple funds, which creates overlap: for example, a company held in both the US index and the semiconductor ETF increases its effective weight. Because only ETF top‑10 positions are shown, total overlap is likely understated. Still, the visible pattern suggests a meaningful concentration in a handful of dominant growth and chip‑related firms.
Risk contribution shows how much each holding drives the portfolio’s overall ups and downs, which can differ from simple weights. Here, the 70% US ETF contributes about 68% of total risk, roughly in line with its size. The 20% Europe ETF contributes only 15% of risk, reflecting its relatively calmer behaviour. The 10% semiconductor ETF is the standout: it contributes over 17% of total risk, far more than its weight. That means this small, focused position punches above its size in terms of volatility, similar to a loud instrument in an orchestra that can dominate the sound even if it is only one player.
This chart shows the Efficient Frontier, calculated using your current assets with different allocation combinations. It highlights the best balance between risk and return based on historical data. "Efficient" portfolios maximize returns for a given risk or minimize risk for a given return. Portfolios below the curve are less efficient. This is informational and not a recommendation to buy or sell any assets.

The risk‑return chart shows this portfolio with an annualized expected return of 17.22% and volatility of 15.22%, giving a Sharpe ratio of 0.97. The Sharpe ratio compares excess return over a risk‑free rate to volatility, so higher values mean better risk‑adjusted performance. The optimal mix of these same three ETFs on the efficient frontier has a higher Sharpe of 1.14, but also materially higher risk and return. The minimum‑variance mix has lower risk and only slightly lower Sharpe. Importantly, your current allocation already sits on or very near the efficient frontier, which suggests the chosen weights are efficient given the holdings used.
Costs in this portfolio are impressively low. The total ongoing fee, or TER (Total Expense Ratio), is about 0.13% per year across all funds. TER is the annual percentage taken by the ETF provider to run the fund, similar to a small membership fee. The core US and European ETFs are especially cheap for broad‑market exposure, while the semiconductor ETF understandably costs a bit more because it tracks a narrower theme. Low costs help more of the portfolio’s gross return stay in the investor’s pocket and can compound into a meaningful difference over many years, particularly for fully invested, long‑term strategies.
