A personal framework built on compounding knowledge and patience. Not a formula — a set of principles I am testing against reality, updated as I learn. The core insight: time, simplicity and discipline beat complexity every time.
Foundation — Non-Negotiable
Rule Zero
The core is a global equity ETF. Without this foundation, individual stocks are speculation. With it, they are intelligent tilts. A global index fund gives you exposure to thousands of businesses, automatic rebalancing at zero effort, and the compounding of the global economy. You cannot systematically beat it — but you can add deliberate exposure to things you understand deeply.
ETF Portfolios — Three Levels of Complexity
VWCE 100%
VWCE — Vanguard FTSE All-World (100%)
Best for: anyone starting out, or anyone who wants zero maintenance. One ETF, globally diversified across 4,000+ companies in 50+ countries. You own Apple, LVMH, Samsung, Nestlé and everything in between. Rebalances itself. Add every month. Do not touch.
VWCE 80%
EXSA 20%
VWCE — Global core (80%)
EXSA — Eurozone equities tilt (20%)
Best for: European investor who wants deliberate home bias exposure. EXSA adds weight to large-cap Eurozone names (Schneider, LVMH, ASML, SAP) and reduces currency risk for EUR-denominated spending. The 20% tilt is meaningful without dominating. Note: VWCE already contains ~20% European equities — this increases it to roughly 35–38% total.
VWCE 63%
EXSA 15%
IQQQ 15%
SMH 7%
VWCE — Global core (63%)
EXSA — Eurozone tilt (15%)
IQQQ — MSCI World Quality Factor (15%)
SMH — Semiconductor ETF (7%)
Best for: investor who wants deliberate tilts with conviction. Three clear bets: European industrial quality (EXSA), quality/defensive factor (IQQQ), semiconductor infrastructure (SMH). Requires rebalancing once a year.
My view
SMH is the tilt I find most compelling — semiconductors are the electricity of the AI era, and the ETF format avoids single-name concentration risk. EXSA makes sense for European investors: Schneider, ASML, LVMH, SAP are world-class businesses that VWCE structurally underweights. IQQQ is a quality/defensive layer — it tilts toward high-ROE, low-leverage, stable-earnings companies that hold up better in downturns. I deliberately excluded emerging markets: 15 years of underperformance vs developed markets is a structural signal, not just bad luck.

Stock Selection — The Ineluttability Framework
Before buying any individual stock, run it through these five questions in order. If it fails any of the first three, stop. The last two refine conviction and sizing.
01
Is this company ineluttable for 2035?
The structural necessity test
Can you imagine the world of 2035 functioning without this company's core product or service? Not "it would be inconvenient" — genuinely structurally necessary. AI compute without NVIDIA-class GPUs: impossible. Cloud without AWS/Azure/GCP: impossible. Payments without Visa/Mastercard rails: extremely hard. Fast fashion brand X without their stores: nobody would notice.
Pass: ASML (only company making EUV lithography machines — zero substitutes), TSMC (manufactures chips for 90%+ of the world's advanced designs), Visa (network effects create a near-irreplaceable infrastructure layer). Fail: most retail brands, most media companies, most traditional banks.
02
Will this company remain the dominant provider?
The IBM test — necessary ≠ safe
IBM was structurally necessary in 1990. Nokia made the most important communication device in 2000. Being necessary today does not mean this company captures the value. Ask: what prevents a competitor from delivering the same necessity better or cheaper? The answer must be concrete — patents, network effects, switching costs, scale economics, regulatory moats — not vague brand loyalty.
IBM: necessary but easily substitutable → lost. ASML: necessary AND the only company on earth with the know-how + supply chain for EUV → safe. Google Search: necessary AND 15 years of training data moat + distribution → defensible (though eroding). ChatGPT/AI: necessary but NOT yet clear who captures the value.
03
Do I genuinely understand the business?
The two-minute test
Can you explain, in under two minutes, without notes: (a) how the company makes money, (b) what drives revenue growth, (c) what the main risk to the thesis is? If you cannot, you do not own the stock — you are renting it from someone who understands it better. Understanding creates conviction. Conviction is what keeps you holding during -30% drawdowns instead of panic-selling at the worst moment.
You should be able to say: "Schneider makes most of its revenue from energy management hardware and software for data centers and industrial facilities. Growth is driven by AI infrastructure buildout requiring power management, and the industrial energy transition. The main risk is a recession in industrial capex or a slowdown in data center spending."
04
Is the valuation reasonable?
Fair price for a great business
A great business at an outrageous price is a bad investment. Use three simple checks: (a) EV/EBITDA or P/E vs historical average — is it in the bottom half of its own 5-year range? (b) Forward PE vs growth rate — PEG ratio below 1.5 is attractive. (c) Free cash flow yield — FCF/market cap above 3% suggests you are not paying for pure speculation. You do not need a precise price target. You need to know if you are in cheap, fair or expensive territory.
Cheap territory = conviction add. Fair territory = hold, small add. Expensive territory = hold existing, do not add. Never buy in expensive territory regardless of how much you believe in the company.
05
Can I hold this through a -40% drawdown?
The honest conviction test
Every great company you will ever own has had, or will have, a -30% to -50% drawdown at some point. MSFT fell 50% in 2022. NVDA fell 66% in 2022. ASML fell 45% in 2022. These were not failures — they were noise in a long-term compounding story. The question is not whether it will happen. It will. The question is: if this stock fell 40% tomorrow with no change in the underlying business, would you buy more? If the honest answer is "I'd sell to stop the pain," your position is too large.
Size accordingly: the position should be small enough that a -40% move does not destabilize your portfolio or your sleep. With a 5% cap per stock, a -40% move = -2% total portfolio impact. That is manageable. A -40% move on a 20% position = -8% total portfolio. That is painful enough to make bad decisions.
My view on the framework
The ineluttability test is the most honest filter I have encountered. Most investment frameworks are complicated precisely to hide the fact that they are guesses dressed in mathematics. This one forces you to answer a simple question clearly. The addition I would make: run the IBM test before any other analysis. It is easy to get excited about a company that is "necessary" without asking whether it will capture the value of that necessity. The history of technology is full of companies that built infrastructure that others monetised — they were ineluttable, but not profitable for shareholders.
From Framework to Action — Illustrative Equity Sleeve
A broad ETF core remains the foundation. Individual stocks sit on top as a concentrated sleeve — no more than 10–15 positions, built around a small number of core compounders and complemented by deliberate satellite exposures. Concentration improves clarity, but only if it stays disciplined.
Core Compounders · max 4
Up to 10% each
Durable moat, strong capital allocation, business clarity, long-term relevance. Highest conviction — sized only when quality AND valuation align.
Satellite Positions
Smaller by design
Narrower themes, cyclical opportunities, or high-quality businesses that don't deserve core sizing. Limits damage from inevitable mistakes.
High Conviction Bet · max 1
One personal bet
A specific, less consensus-driven idea. Tied to a particular tilt, analytical edge, or deeper familiarity. Must remain size-limited and intellectually earned.
Water + hygiene + infection prevention. 3M+ customer locations, retention >90%. Ovivo adds AI infrastructure water exposure.

Mental Models
⏳
Compounding needs time and continuity
At 8% annual return, money doubles every 9 years. But only if you stay fully invested. Every interruption — selling in panic, moving to cash, trading on noise — resets the clock. The single most important investment decision is to not sell.
🧭
Business quality over price timing
A great business at a fair price beats a mediocre business at a cheap price over 10 years. Focus on identifying exceptional businesses first. Be patient on price. But do not wait for the "perfect" entry — it rarely arrives.
📉
Drawdowns are tuition, not losses
MSFT fell 50% in 2022. NVDA fell 66%. These were not failures — they were the price of long-term participation. The investors who held through those periods are the ones who compounded wealth. Volatility is the fee you pay for returns above cash.
🔬
Your edge is depth, not speed
You cannot trade faster than algorithms. You cannot have more data than institutions. Your edge is understanding specific businesses deeply over a long time horizon — and having the patience and conviction to wait while the market catches up to what you already know.
📊
Valuation bands, not price targets
Nobody knows the exact fair value of a business. Cheap / Fair / Expensive zones are honest. Buy in cheap zones. Hold in fair zones. Consider trimming in expensive zones. Price targets create false precision and encourage trading.
🪞
Know your own temperament
The best investment strategy is the one you can actually execute during a bear market at -30%. If a drawdown would cause you to sell, you are overallocated. Risk tolerance is not how much risk you want — it is how much pain you can absorb without making bad decisions.
Operational Rules — Satellite Equity Allocation
01
Maximum 5% per single stock
With a 10–20% satellite sleeve, this means 2–4 positions at any time. If a position grows beyond 5% through appreciation, trim it back. Rebalancing is not admitting defeat — it is discipline. Concentration is the enemy of sleep.
02
Buy and hold — ignore short-term noise
A red candle is not a signal to exit. The holding period should be measured in years. Every trade costs taxes, fees, and the risk of being wrong on timing. The question is always: "Has my thesis changed?" If not, there is no reason to act.
03
Add gradually — monthly or quarterly
Never deploy all capital at once. Use fixed intervals to build positions. Dollar-cost averaging means you will buy at different prices over time — some good, some bad, average out better than you think. "Time in market" beats "timing the market."
04
Equal-weight positions initially
The temptation to overweight your "best idea" is strong and usually wrong. Your best idea is the one you have thought about most — not necessarily the one that will perform best. Equal weighting forces intellectual humility.
05
Review quarterly, not daily
Daily monitoring creates emotional noise and leads to worse decisions. A quarterly review is sufficient to confirm the thesis is intact and no position has drifted. Research consistently shows that investors who check their portfolios less frequently perform better.
