Trading is all about making money, the question is who's making the money? Buffett once said a famous saying, 'The stock market is a voting machine in the short term, but a weighing machine in the long term.'. In the short term, the price of a stock is determined by the transaction between the buying and selling parties, and is a vote on the price. That is to say, after you vote to buy a certain stock at a certain price, you also hope that someone will vote to buy your stock at a higher price in the future, so that you can make money. If no one votes at a higher price in the future, you will never make money, which is the "passing the buck" mentioned in the title. This is a psychological game, because there are a large number of voters in the market, and there will be psychological influences between them, so trend analysis is formed. And in the long run, the stock market is a weighing machine, what is its weight? It refers to the level of operation and profitability of a company. The ultimate goal of a company is to make profits, and stocks are a part of the company's equity and have the right to share the company's ultimate profits. So we can see that as profits grow rapidly, many companies' corresponding stock prices will also increase. Because if profits only increase and stock prices do not, a very interesting scenario may occur, where the company's annual profits may eventually equal its market value, and there will be a lot of capital to buy it out. It takes a year to recoup the investment, and I'm afraid everyone will wake up laughing. If this profit is real and can be distributed, this phenomenon will never happen. So investing in the stock market is the money that companies make long-term profits from.
