→ WHAT IT COVERS Clay Finck reviews his 2025 portfolio additions including Meta, Interactive Brokers, and Booking Holdings, explaining his shift toward US large caps, valuation frameworks, international diversification strategies, and how value investing principles shape career decisions and personal happiness optimization. → KEY INSIGHTS - **Sidecar Investing Framework:** Invest alongside generational CEOs like Zuckerberg at Meta and Peterffy at Interactive Brokers, then hold long-term. Meta fell from $750 to below $600 after Q3 earnings despite strong fundamentals, creating entry opportunity at 22 adjusted PE while compounding earnings at 20% annually with WhatsApp monetization still early stage. - **Interactive Brokers Growth Runway:** IBKR achieved 30% annual account growth over five years with minimal marketing spend, demonstrating organic customer acquisition through superior product. Currently serves 4 million accounts globally versus massive addressable market, suggesting potential to 10-20X customer base long-term despite $100 billion valuation and premium pricing. - **International Valuation Arbitrage:** Poland offers compelling opportunities with companies like Dynopolsko trading at lower multiples than US peers. Japan presents cheapest valuations globally but requires underwriting 16% annual growth versus 12% for US companies to compensate for yen currency risk and potential depreciation against dollar over holding period. - **Portfolio Construction Discipline:** Build full 10% positions only with high conviction and attractive valuation. Topicus deployed €780 million in acquisitions during 2025 versus €150 million in 2024, representing 5X increase that should drive future earnings growth despite stock trading at 17 times free cash flow, lowest multiple in company history. - **Career Margin of Safety:** Apply value investing principles to personal finances by maintaining low fixed costs and avoiding consumer debt. Taking 50% pay cut to join TIP became possible through living below means with no car payment or mortgage, creating optionality to pursue meaningful work over maximizing income during twenties. → NOTABLE MOMENT Clay describes how Thomas Peterffy arrived in New York at age 21 with no English skills or resources, then built Interactive Brokers into a $100 billion business where he still owns over 70% of shares, exemplifying the American dream and outsider CEO characteristics. 💼 SPONSORS [{"name": "LinkedIn Jobs", "url": "linkedin.com/studybill"}, {"name": "AWS AI", "url": "aws.com/ai/rstory"}, {"name": "Unchained", "url": "unchained.com/preston"}, {"name": "Vanta", "url": "vanta.com/billionaires"}, {"name": "Shopify", "url": "shopify.com/wsb"}] 🏷️ Portfolio Management, Quality Investing, International Markets, Career Development, Value Investing Philosophy
