Investors can know which stocks the national team holds by looking at the "national team" in trading software, such as straight flush software.
Ordinary investors often say that the support of the national team means that these institutions enter the stock market and start to pull up stocks. However, the national team will not support the market at will, unless the stock market is bad and the economy is seriously declining. Moreover, the entry or support of the national team is not for profit, but for maintaining the security and stability of the capital market.
Therefore, the support of the national team can be simply understood as: whenever the market plummets and the popularity is lax, the funds of these state-owned enterprises will enter, so as to stabilize the confidence of investors and the development of the securities market.
