My Honest Advice to Everyone Buying ETFs + Steal This Plan for the Perfect Portfolio
In this video, Mario Lochner explains the Core-Satellite Strategy to build the perfect portfolio. He reveals why most investors fail (overconfidence, impulsiveness) and how to achieve long-term success through automation and psychological tricks.
🧠 The Wealth Multiplier- The earlier you start, the stronger the compound effect. Example: €1 at 10 % annual return grows to €647 by age 65 if you start at 0, but only €88 if you start at 20.
- A JP Morgan study shows the average investor earns only 1.9 % – worse than any asset class.
- Researcher Hendrik Bessenbänder found that only 2.4 % of all stocks create lasting net wealth. The rest underperform Treasury bills.
- Beta = market return (systematic), e.g. via an ETF like the MSCI World.
- Alpha = excess return (unsystematic) through individual stocks, crypto, or targeted bets.
A solid core (70–85 % of the portfolio) of broadly diversified ETFs captures market returns. Around it orbit satellites (15–30 %) for alpha – e.g. single stocks, gold, or crypto. This calms your psychology and prevents decision errors.
🔍 Building the Perfect Core- Define the capital’s purpose (wealth building, retirement, etc.).
- Four conditions: reflects the desired return source, broadly diversified, cost-efficient, crisis-proof.
- Simplest solution: 100 % all-world ETF (e.g. Vanguard FTSE All‑World or SPDR MSCI ACWI).
- Avoid fake diversification: MSCI World, S&P 500, and Nasdaq 100 overlap heavily (many identical top holdings).
Each satellite must have a clear thesis. Before buying, answer 5 questions:
- Strategic or tactical?
- Primary mission?
- Neutral alternative?
- How to measure success?
- What disproves the thesis, and what is the maximum acceptable loss?
Example: Max satellite weight = acceptable portfolio damage (max 2 %) divided by conservative stress loss (50 %) → max 4 %.
🏦 Example Portfolio with €100,000- Core (70 % = €70,000)
- North America: €32,200
- Japan: €6,300
- Europe: €16,100
- Emerging Markets & Pacific: €15,400
- Satellites (30 % = €30,000)
- Bitcoin: €6,000
- Individual stocks: €15,000
- Gold: €9,000
