Fund jiacang does not mean buying directly, but buying again on the original basis. For example, an investor holds 200 shares of a fund and buys 100 shares on the basis of these 200 shares because he is optimistic about its later upside. This is called jiacang. Direct purchase refers to the fund that investors buy for the first time, which is different.

Investors can increase their positions when they are rising or when they are falling. Adding positions when rising is generally more suitable for short-term investment, and adding positions when falling is to reduce the cost of holding funds and is more suitable for long-term investment.
