Very early in Sprotts Gold Equity Fund there is a table showing investment returns of gold producers ranked according to size ..link below
Small cap producers ROI in 2023 was nearly 26% which blew away large caps...I never invest in them ..followed by medium etc.
This is because small caps can explode out of the market cap gate as they quickly expand their production or, as is usually the case, are taken over..
