As a short-term indicator, the seven-day annualized rate of return can roughly refer to the recent (recent seven days) income level, but it cannot fully represent the actual annual income of this fund. The income per 10,000 funds is the average income per 10,000 funds per day, and the unit is RMB. Because the net value of money per unit is fixed at 1 yuan, the unit income of 1 10,000 shares is the profit of the day when the investment is 1 1,000 yuan. For measuring the trend of funds, the income per 10,000 funds is more accurate.
