WS Montanaro Better World
Last updated: 2026-09-11
The Verdict
WS Montanaro Better World charges an expense ratio of 1.00%. On a $100,000 portfolio, that's $1,000 per year in fees, and it scales with the amount invested. Supreme.PM's decoded model tracked it at only 27% correlation over the measured period, so it should not be treated as a substitute for this fund, for a flat monthly subscription that does not change with portfolio size.

Alpha After Fees
Supreme.PM's model shows 27% correlation with WS Montanaro Better World over the measured period. That is weak tracking: the model does not reproduce this fund's return pattern, and a negative figure means it moved in the opposite direction.
Fee Analysis
WS Montanaro Better World charges 1.00% of assets annually. Supreme.PM charges a flat monthly subscription instead, so its cost does not rise as a portfolio grows.
