Non-tradable shares refer to the equity difference represented by shares. In theory, how many shares you own corresponds to how many shares you own. At the end of 2005, the purpose of the share-trading reform in China was to solve this problem, because at that time, the same shares had different rights and could not be circulated. Money fund refers to a fund that invests in short-term securities in the money market. The Fund's assets are mainly invested in short-term monetary instruments such as treasury bills, commercial paper, bank time deposit certificates, government short-term bonds, corporate bonds and other short-term securities, which are suitable for conservative investors to participate.
