That's right. But because you made a fixed investment, you accumulated a little more than 30 thousand, and the initial investment was small. If the funds behind you are generally upward, the investment cost in the later period will increase and the overall cost will be raised. On the contrary, if the funds are backward, the cost of your re-purchase will be reduced, and the overall cost will be reduced. This is the characteristic of fixed investment. If the market is not good, the risk will be reduced and the income will be relatively low.
