Buying at a high point of a fund refers to buying when the point and price of the fund are high. Buying a fund at a high point is easy to be trapped, with high cost, high risk, low expected return and high loss probability.
It is more cost-effective for the fund to buy at a low point, with low buying cost, low risk, high expected return and high profit probability. Investors should choose to buy at a low point when trading funds.
