Is it profitable to exchange the change for other funds in those days?
There is no gain in those days when change is exchanged for another fund. Only by changing the fund to confirm the share will there be income. Therefore, it is not recommended to change funds frequently with small change, which will affect the income.
When choosing a money fund with small change docking, we can consider the past income, fund manager, fund size and establishment time of the money fund, and choose a good fund to hold for a long time.
Was it cost-effective to change the change into other funds in those days?
It was not cost-effective to exchange small change for other funds at that time, because it would lose income, so it is not recommended to change it frequently. In addition, it should be noted that there is little difference between money funds, which are all invested in the money market, so the risk is relatively small and the fund fluctuation is relatively small. Long-term holding is more likely to make money and less likely to lose money.
In addition, some small fluctuations between monetary funds are normal. Perhaps the annualized rate of money fund is relatively low today, and it will rise tomorrow, so don't pay too much attention to short-term fluctuations, just pay attention to long-term gains.
