Why diversified cores matter now

Factor crowding and mega-cap dominance make diversification an active design choice for professional portfolios.

When a handful of names dominate index returns, the opportunity cost of an undiversified core rises. Institutions still need liquid, transparent equity exposure — but they do not need to outsource concentration risk to the benchmark.

Maximum Diversification® offers a systematic alternative: keep the investable universe, change the objective function. No narrative stock-picking; a quantitative process aimed at maximising diversification under real-world constraints.

This note is intended for professional investors evaluating core equity replacements or complements to market-cap beta.
