Because the redemption of the fund before the trading day 15: 00 calculates the income of the day, you can sell it according to the rise and fall of the fund's constituent stocks before you predict that the market will fall. If most of the constituent stocks rise, they can be sold, and the fund's income on that day is likely to rise. If most of the constituent stocks of the fund fall that day, the fund is likely to fall that day.

If it is predicted that the market will fall soon, it can be redeemed before 15:00 on the same day.
