π§ Portfolio Composition & Strategy
Overall Portfolio Breakdown
Last Update: 29-Mar-2026
πΉ Active Investing (100%)
High-Quality Growth Stocks (100%) β Focused on durable, fundamentally strong businesses with long-term growth potential.
High-Growth & Speculative Plays (0%) β No exposure currently; reserved for higher-risk swing trades.
πΉ Note: 5% of my portfolio is currently held as cash in a separate money market account, ready to deploy for new opportunities in 2025.
Why I Prefer an Active Investing Strategy
As both a long-term investor and occasional trader, I know how hard it is to outperform the market consistentlyβespecially in recent years, with US indexes like SPY and QQQ delivering double-digit returns and outperforming +90% of active managers. The reality is that outpacing the market year after year is tough.
But I also believe individual investors have an edge over professionals. We donβt need to justify our performance every quarter or compare returns to benchmarks in the same way institutions do. This freedom allows us to stay patient, focus on long-term gains, and ride our investments with minimum pressure.
For me, itβs not just about returnsβitβs also about staying engaged, learning from market trends, and having the freedom to explore high-quality, durable growth stocks and high-growth speculative plays that intrigue me.
π Quarterly Report
March 2026 Portfolio Update β Another Month of the Same Thing: Volatility.
Volatility was once again the name of the game in Marchβ¦ wait, havenβt I already said this this year?
Yes, January and February looked very similar. But now, the indexes appear to be breaking down as the bear market in the MAG7 is accelerating.
Portfolio performance hasnβt been great heading into the end of Q1. That said, I continued adding new capital and made a couple of rotations: one within the MAG7 and another within my Nordic small-cap exposure.
Thanks for following along,

Portfolio Composition by Industries & Geographies
Last Update: 29-Mar-2026
I try to limit the nΒΊ of long-term holdings to 15. Currently, I own 11 names down from 12 positions at the end of Q4 2025.
For my long-term portfolio, diversification is non-negotiable.
Of course, Iβm well aware of the phenomenal outperformance of U.S. equities over the past decade, with the S&P 500 and Nasdaq leading the way. U.S. equities have benefited from a combination of factors: a pro-growth capitalist environment, the dominance of the dollar, investor-friendly policies, and technological leadership. Add to that, robust financial institutions and a proactive Federal Reserve, and it becomes clear why the U.S. market has outpaced much of the world (nod to China).
However, markets are inherently cyclical, and conditions may change. The chart below speaks for itself:
My portfolio weighting reflects the current reality of U.S. dominance, but markets have a habit of shifting when most people least expect it. As a long-term investor, I believe spreading investments across industries, sectors, and regions builds resilience. Diversification cushions against regional risks and taps into new growth opportunities, ensuring the portfolio remains durable through market shiftsβbecause staying power matters as much as returns.
π Portfolio Performance
Last Update: 29-Mar-2026
My original portfolio dates back to November 2017, which I believe is a long enough horizon to gauge performance. Iβm not the same investor and trader I was thenβmistakes were made, but important lessons were learned.
I only felt completely at ease with my long-term portfolio's composition, strategy, and risk tolerance at the end of 2022, so Iβll be sharing returns from January 2023 βalso coinciding with the consolidation of my entire long-term portfolio in one single broker (excluding Swing Trades, if I play them I do it on a different broker).
I use both Time-Weighted Returns and Money-Weighted Returns to measure my portfolioβs performance. Together, they provide a more complete picture.
I go into more details about this approach in my article: π Calculating Portfolio Returns & Why Investing is Personal
Note: Returns shown by Interactive Brokers are calculated in EUR and may be affected by FX volatility.

While YTD or Monthly returns are commonly shared by many, they can be misleading for assessing long-term returns. I consider at least a 5-years horizon is more appropriate for evaluation. The compounding effect means that past performance significantly impacts our overall return, making longer-term perspectives more revealing.
I am quite satisfied with my portfolio returns so far, but it's definitely too early to evaluate long-term performance.
β Valuation Metrics
Last Update: 29-Mar-2026

Here are key metrics of my current Portfolio I use to monitor and assess its quality:
Growth & Durability β
Double digits forward EPS growth
Double digits top line and EPS CARG (3y-avg and 5y-avg)
Standout Margins & Operational Excellence β
Operating margin >25% and EBITDA margin >30%
High FCF Margins >20% and Net Profit Margin around 20%
Capital Efficiency β
High Return on Invested Capital (ROIC) >15% and high ROCE > 20%, indicating an efficient use of invested funds to generate profitable returns
FCF Conversion > 100%, showing high efficiency to turn profits into actual cash flow
Financial Sustainability
Fwd. FCF Yield - indicating ability to generate cash and sustain operations - at 3.12%. A bit low currently as some of my heavy-weighted companies are richly valued and going through a high Capex cycle π‘
Positive Forward P/E, EV/FCF and EV/OCF, although currently trending at a relatively high multiple π‘
Low Leverage, Low Dilution β
Net Debt/EBITDA < 1, reflecting ability to manage debt and a good financial health
Total Debt against Capitalization around 40%, below the 50% ratio of the S&P 500 index constituents.
Shares Outstanding Growth of the overall Portfolio is virtually at 0%. Dilution is minimal which is key as a long-term shareholder.
π NOTE: Some positions in my long-term portfolio are growth companies or have non-normalized earnings, which can distort valuation multiples (like P/E, EV/FCF and FCF Growth).
