Leveraged funds can be purchased through floor trading, provided that a shareholder account needs to be opened. You can also open a shareholder account first, buy the parent fund off-site and convert it into a list of two or more leveraged fund products on the market. The leveraged funds you bought in the secondary market all have parent funds, and the fund companies classify the leverage in the parent funds as Class B shares. Those without leverage are classified as Class A shares. After buying share B, if the net value of the fund rises when the market rises, the net value of share B will be enlarged according to the leverage ratio. If it falls, the net value will decrease rapidly. A share generally enjoys the agreed fixed income, and when the market falls, B share makes up for the loss. When the market rises, the excess return belongs to B share, and because of this, the fluctuation of B share will be relatively large. Due to the market decline, the leverage ratio of leverage share is increasing. In extreme cases, high leverage will trigger the downward irregular conversion mechanism, resulting in the reduction of the multiple from high leverage to initial low leverage.
