@KobeissiLetter This is TSMC, not Taiwan. TSMC alone is ~60% of the Taiex. Compare that to the FTSE 100: Shell, AstraZeneca, HSBC, Unilever. The UK market is diversified; Taiwan is a single-firm call option on AI capex. Impressive number, statistically fragile concentration.
one company being 40% of an entire country's stock market is not a strength. it's a concentration risk that makes the entire taiwanese economy a leveraged bet on whether AI scaling laws hold. if TSMC's revenue growth slows by 10%, taiwan's market cap drops $400B. the UK market looks flat by comparison because it's diversified across finance, energy, pharma, and consumer goods. diversification looks boring until the single-stock thesis breaks.
the geopolitical layer makes it darker. taiwan's $4.14T market cap sits on an island that china considers a breakaway province. every dollar of foreign capital flowing into TSMC is a dollar betting that the strait of taiwan stays peaceful. investors are simultaneously pricing in the most optimistic AI growth trajectory AND the most optimistic geopolitical outcome. one of those bets failing wipes out the other
