Tik Tok's son who talks about stocks is a liar. Because. Stock investment means buying and selling stocks and making profits by doing stock business. The core content of stock trading is to realize arbitrage through the stock price difference between buying and selling in the securities market. Don't believe that it is a routine. Stock is a part of the ownership of the joint-stock company, and it is also a certificate of ownership issued by the joint-stock company. It is a kind of valuable securities that the joint-stock company issues to all shareholders as holding certificates to raise funds and obtain dividends and bonuses.
