From the essence of the stock market, it has a very useful function - achieving a positive cycle. If more and more excellent companies are listed on the stock market, and if these companies are in a long-term upward trend, they can expand their business scale through stock market financing, create more goods and services, and investors can increase their wealth by investing in these companies. After people's wealth increases, they will consume more, and consumption will further drive companies to expand production. This is a typical positive economic cycle.
