01
A 10x mindset
I look for companies that, in my view, have the potential to grow many times from today’s value. That is a way of thinking about opportunity — not a target, projection or guarantee of any particular return.

Investment philosophy
A long-term approach to exponential change
I look for businesses that can compound over many years — in technology, in markets, and in the future those businesses are building. Nothing here is a performance promise or a recommendation.
02
A long-term horizon
I invest with patience. Short-term market noise usually matters less than the quality of the business and the time it needs to compound.
03
Focus on deep tech
I pay close attention to areas where technology is reshaping industries — including artificial intelligence and semiconductors, and space.
04
Contrarian value
I also look for high-quality companies that have been unfairly marked down by short-term sentiment, and try to capture that value through fundamental analysis.

S&P 500 figures are total returns (price change plus reinvested dividends). Calendar years 2022–2025 are from S&P Dow Jones Indices, U.S. Equities Market Attributes, December 2025. 2020, 2021 and 2026 year-to-date (as of market close 12 November 2026) are from Slickcharts, which compiles S&P 500 total returns including reinvested dividends; the 2022–2025 Slickcharts figures match the S&P Dow Jones Indices total-return numbers. Portfolio figures are as of 13 November 2026. The 2026 columns therefore end one market session apart. The portfolio series begins with the first published monthly data in March 2020, so 2020 is not a full calendar year for the portfolio and is not directly comparable with the S&P 500’s full-year 2020 figure.

About
Background and approach
I am a long-term investor based in Prague, and a certified Popular Investor on eToro. My public eToro profile puts it this way:
I manage a diversified, long-term portfolio focusing on deep-tech companies with strong growth tailwinds. The aim is high-quality businesses that still look undervalued relative to their long-term potential.
I also take a contrarian view: looking for quality companies that have been unfairly penalized by short-term market sentiment, and trying to capture that value through patience and rigorous fundamental analysis.
I write market analysis in English — including on themes such as hyperscaler AI capital spending — and I host Curious Mind Investing, a podcast of 60- to 75-minute conversations with other eToro Popular Investors about investing principles and strategy, not stock tips.
