1. The "cargo owner" sets an issue price when sending the stock---the goods to the securities market. After that, the buyers and sellers in the securities market decide the price on their own. A buys an apple from the owner for 1 yuan and sells it on the market for 1.5 yuan. If someone is willing to buy it, the price of the apple will rise to 1.5 yuan. If there are too many apples, or there are too many pesticides, and no one wants the apples, people who have apples may price them at 0.5 yuan. Some people think they can buy them, so they buy them for 0.5 yuan. In the end, Apple only costs 5 cents. Stocks are similar.

2. Not necessarily. Think about it, if all the apple sellers want to sell their apples at a price of 50 yuan, there will be ten times the number of buyers in the market who want to buy apples, but they are only willing to pay 50 yuan. 1 yuan, then the two parties cannot complete the transaction, and the price of Apple will not fluctuate. We can only maintain a stalemate and see who is willing to give in. Of course, if there are too many crazy people and they buy an apple for 50 yuan, many crazy people who follow the trend will give up the original intention of buying it for 1 yuan and follow up with the purchase. The apple seller looked at it and realized that these fools would buy it for 50 yuan, so I wouldn’t sell it for 50 yuan, but I would sell it for 55 yuan. . . If you follow the trend, the price of apples will go up. After all, there will be more people buying and fewer selling.
