Different graded funds have different levers. Judging from the current mainstream classified stock base, the ratio of general priority share to enterprising share is 1: 1 or 4:6, that is, the initial leverage is 2 times or 1.67 times. As the net ratio of the two changes, the leverage will also change. Generally speaking, if the net value of enterprising share increases, the leverage will decrease, and if the net value of enterprising share is less, the leverage will increase. Therefore, when investing, we must be clear about the size of leverage and the proportion of risk and income amplification.
