Initial leverage: the initial leverage is the leverage ratio when the fund is issued, that is, the ratio of the sum of A share and B share to B share. At present, the proportion of mainstream products in the market is mostly 1: 1 or 4: 6, so the initial leverage is 2 or 1.67.

Net leverage ratio: the net leverage ratio is the ratio of the net growth rate of the progressive part of the graded fund to the net growth rate of the parent fund.

Price lever: it is the change multiple of B share price relative to the net value of the parent fund, that is, the total net value of the parent fund divided by the total market value of B share.
