Limiting Concentration Risk in Global Equities
Global equity benchmarks suffer from severe structural crowding. A handful of mega-cap technology stocks now dictate the performance of traditional market-capitalization-weighted indices. Taiwanese allocators know this vulnerability intimately. The S&P Taiwan BMI currently runs with an 83% weighting concentrated strictly in information technology.
To break this concentration loop, index providers are engineering explicit structural caps. The new S&P TIP Global AllCap Index strips down the sprawling 15,000-stock S&P Global BMI universe. It filters the field to just over 2,200 companies across 48 global markets, demanding a strict $1bn minimum float-adjusted market capitalization. The methodology targets 90% of total float market cap but imposes hard country guardrails. Large market deviations are capped at 3% above or below their baseline weights. Smaller markets face a strict 0.5% boundary. This rules-based architecture forces capital redistribution. It actively prevents a single market or a cluster of tech giants from commandeering the index, offering a necessary pressure valve for allocators seeking authentic global diversification.
