Before 2002, the open-end funds managed by fund management companies disclosed their net value through newspapers and bank outlets, which was difficult to cover all investors in the securities market and restricted the development of open-end funds. At the request of fund managers and investors, after evaluation by the technical department, on the premise of ensuring the safe operation of the market, Shenzhen Stock Exchange decided to use the quotation publishing system to reveal the net value of open-end funds.
Shenzhen Stock Exchange has compiled the prompt code and abbreviation of the net value of open-end funds, and revealed the net value of each hundred fund units the day before through the "before closing" column in the quotation system. Investors can check the net value of 100 units of this open-end fund on the previous day through the net value disclosure code of this open-end fund.
In order to standardize the compilation of open-end fund net value disclosure code in Shenzhen Stock Exchange and maintain the principle of "openness, integrity, compatibility and security", Shenzhen Stock Exchange has specially formulated the compilation rules of open-end fund code and abbreviation. The net disclosure code of open-end funds consists of six Arabic numerals, the first two digits "16" or "15" represent open-end funds, the middle two digits are the codes of fund management companies, and the last two digits are the numbers of all open-end funds issued by fund management companies. The abbreviation of open-end fund consists of four Chinese character strings or strings with a length of no more than four Chinese characters. For example, Rongtong's new blue-chip open-end fund has a net disclosure code of "16 160 1", which is referred to as "new blue chip" for short.
