it should be "equal weight fund".
Equal weight is a kind of weight method used in index compilation, which is to give each index component the same weight and adjust it regularly. The traditional index is generally market value weight, and its weight in the index is determined by the market value of constituent stocks.
At present, the only equal-weight index fund established in China is Bosera Super-market ETF, which tracks the Shanghai-Shanghai Super-market Index, and each constituent stock accounts for 5% of the weight.
