The 7-day annualized rate of return is a comprehensive calculation of 10,000 returns in the last seven days. If the 7-day annualized rate of return is very high, it is very likely that there will be a high 10,000 fund returns one day in the short-term 7 days, resulting in a high 7-day annualized rate of return, but the recent 10,000 returns are very low, which is a frequent situation. At the same time, on the contrary, it is normal to see that the fund's income is extremely high, but the annualized rate of return on the 7 th is very low, which proves that the other six data are very low. Even if one of them is very high, it can't pull the comprehensive data on the 7 th.

Therefore, the 7-day annualized rate of return fluctuates greatly, mainly because it cannot be represented by the figures of the last 7 days 1 year.
