This is an index fund, which gains better than most funds in the "bull market", but the losses in the "bear market" are also amazing. The investment target of the Fund is the constituent stocks of the 50 index, so the trend of the constituent stocks determines the income of the Fund. If your investment style is aggressive and can bear large losses, you can consider investing in the index economy. (Note: Index funds have the highest risk of venture capital among fund types. )
