There is a high-profile index in the world, that is, msci index, which is the most used benchmark index by portfolio managers around the world. According to relevant statistics, the msci index of Morgan Stanley Capital International is based on more than 90% of its institutional assets in North America and Asia, with total assets reaching $3.7 trillion, exceeding China's current foreign exchange reserves. What is the use of msci index? The biggest use of msci index is to bring medium and long-term incremental funds to the A-share market and help A-shares achieve internationalization. The most direct way is to add China A shares to msci. On the one hand, it recognizes that China's stock market is basically mature and has a certain degree of openness, and it can play an important role in the world financial market. On the other hand, it can attract more equity funds attached to and invested in the domestic market and increase the openness of the mainland stock market. On the other hand, it also promoted the internationalization of RMB. In the current context, the A-share market is usually called the retail market, and the index often rises and falls. After the introduction of international capital, China will gradually turn into an institutional market, so there will be a long-term bull market. There are obvious long-term suspended stocks in the A-share market, such as Deep Development and Xinwei Group, which greatly affect the normal trading of the market, but msci can change these. Generally speaking, the arrival of msci index is conducive to the formation of the long-term bottom of A-share market, and at the same time it can add another fire to the internationalization of RMB.
