Diversification
Index investing, home country bias, market-cap weighting, and the cost of going too narrow.
Index Investing
How a single broad market ETF captures the equity risk premium without requiring further decisions, and why most investors can stop here.
Home Country Bias
Why the natural preference for domestic investments varies dramatically in cost depending on where you live, and why currency risk concerns are often overblown.
Market-Cap Weighting
Why market-cap weighting is a feature of index investing rather than a flaw, and why concentration concerns are overblown compared to individual stock portfolios.
Single-Country Risk
Why every single-country concentration should be a deliberate choice with full awareness of what is excluded, illustrated through Singapore and China examples.
