1. Global Equity Core – FTSE All-World ETF
(Invesco FTSE All-World UCITS ETF, accumulating)
This building block forms the foundation of the portfolio. It invests broadly across several thousand companies from both developed and emerging markets, thereby covering almost the entire globally investable equity universe.
Its key advantage lies in maximum geographical and sector diversification combined with very low ongoing costs. Individual countries, industries, or companies may underperform over long periods – but this is of little consequence here, as the strategy consistently reflects global economic development as a whole.
The accumulating structure is also tax-efficient, particularly for long-term investors, since returns are automatically reinvested. This building block therefore represents “the market itself” – without forecasts, without bets, and without opinions.
2. Quality and Stability Anchor – Berkshire Hathaway
(Berkshire Hathaway Inc.)
Berkshire Hathaway deliberately complements the global ETF not in an index-like manner, but from an entrepreneurial perspective. The company combines holdings in insurance, infrastructure, energy, transportation, manufacturing, and consumer goods, and has followed an exceptionally disciplined capital allocation approach for decades.
Particularly attractive for a universal strategy is the combination of
• high return on equity,
• low leverage,
• substantial liquidity reserves,
paired with a long-term-oriented management philosophy.
Since Berkshire does not pay dividends but reinvests profits internally, it also offers a tax advantage. Within the portfolio structure, this building block acts as a stabilizing counterweight to purely market-capitalization-weighted indices – with a slightly defensive character, yet without sacrificing long-term growth.
3. Growth Accelerator – NASDAQ-100 ETF
(Xtrackers NASDAQ 100 UCITS ETF)
This building block is deliberately more concentrated and serves as the portfolio’s growth engine. The NASDAQ-100 brings together leading technology and innovation-driven companies that benefit disproportionately from productivity gains, digitalization, and scale effects.
Naturally, this concentration comes with higher volatility. Within a clearly structured overall strategy, however, this is precisely the intention: this ETF provides long-term return potential without taking on single-stock risk.
By limiting this position to a clearly defined share of the portfolio, overall risk remains manageable. At the same time, this building block allows structural growth trends to be captured without the need for constant reallocations or forecasts.
4. Liquidity and Stability Component – Euro Overnight ETF
(Amundi Smart Overnight Return UCITS ETF)
The fourth building block fulfills a central and often underestimated role: stability, flexibility, and liquidity.
This ETF tracks short-term euro money market rates and serves within the portfolio as
• a low-risk parking place,
• a rebalancing reserve,
• a psychological buffer during volatile market phases.
Especially for investors who actively rebalance their portfolios or deliberately add exposure during market downturns, this component is essential. It reduces overall portfolio volatility without exiting the market entirely, while remaining transparent, cost-efficient, and simple to handle from a tax perspective.
Interaction of the Building Blocks
Together, these four elements form a robust, low-maintenance, and scalable system:
• global breadth
• entrepreneurial quality
• targeted growth
• defensive stability
The allocation can be flexibly adjusted to life stage, risk tolerance, and personal objectives without changing the underlying structure. This is precisely where the universal character of the strategy lies:
a simple framework capable of supporting many different life realities – over years and decades.
