What are the factors that lead to the rise and fall of stock prices?

First, the macroeconomic pattern. This is the decisive factor. It is the internal cause. Is fundamental.

Second, people's psychological activities. This factor affects the volume and price.

Third, national policies. The state generally does not interfere. Only when the country thinks the stock market is too outrageous.

There are many factors that affect the rise and fall of stock prices, just like the weather.

However, the most essential force of stock price fluctuation is always the strength of supply and demand. The buyer is powerful, the stock price rises, the seller is powerful, and the stock price falls.

Therefore, the factors that can promote the change of buying and selling power are the fundamental factors that determine the fluctuation of stock prices.

When a company has the hope of making substantial profits in the future, profit-seeking capital will buy vigorously, which will lead to a rise in stock prices, which is the most basic force to promote all stock prices to rise.

On the contrary, when a company's profitability declines, everyone will sell hedging, which will lead to its share price falling.

This is explained from a fundamental point of view.

There are also technical and trend factors. Cash out when a stock rises too much. If the seller's power expands sharply in a short time, it will induce a sharp decline.

In the same way, a stock has been falling for a long time, and everyone is expecting a rebound. In the short term, the buyer's power expands sharply, which usually induces daily limit.

These are just some superficial and fundamental reasons. And there are many factors that will affect it, so you need to figure it out yourself!

Although there are many factors that affect stock price fluctuation, the analysis of these factors can start from the following three points:

(1) The stock price has its intrinsic value, and the stock price fluctuates around its intrinsic value. Intrinsic value determinism is the basis of fundamental analysis.

(2) The stock price fluctuates with the change of investors' psychological expectation of various factors, and the psychological expectation theory is the cornerstone of technical analysis;

Supplement to the question:

Principle of stock auction trading

First, the bidding principle:

Securities trading in a stock exchange shall be conducted by competitive bidding in accordance with the principle of "price first, time first".

Second, the bidding method

China Stock Exchange adopts two bidding modes: call auction mode and continuous bidding mode.

According to the regulations of Shanghai Stock Exchange, the opening time of call auction is 9: 15 ~ 9: 25, and the continuous bidding time is 9: 30 ~1:30, 13: 00 ~ 15: 00 every trading day.

According to the regulations of Shenzhen Stock Exchange, the opening time of call auction is 9: 15~9:25, and the continuous bidding time is 9: 30 ~1:30, 13: 00 ~ 14: 57.

Three, call auction to determine the transaction price principle:

1, the price that can achieve the maximum turnover.

2. The transaction price of all buying declarations above this price and selling declarations below this price.

3. The price at which at least one of the buyers or sellers completes the transaction at the same price.

If more than two declared prices meet the above conditions, the Shenzhen Stock Exchange shall take the price closest to the previous closing price as the transaction price;

On the other hand, the Shanghai Stock Exchange stipulates that the declared price to minimize the unfinished business volume is the transaction price. If there are still more than two declared prices that make the unfinished business meet the above conditions, the intermediate price is the transaction price.

All transactions in call auction are made at the same price.

If the entrusted auction fails to close, it will automatically enter the continuous auction.

Four, the principle of determining the transaction price in continuous bidding:

1, the highest bid is the same as the lowest bid, and this price is the transaction price.

2. When the declared purchase price is higher than the lowest declared selling price disclosed immediately, the lowest declared selling price disclosed immediately is the transaction price.

3. When the declared selling price is lower than the highest declared buying price disclosed immediately, the highest declared buying price disclosed immediately is the transaction price.

10. 1 yuan to 10.2 yuan is the principle of price priority. If someone pays a high price, of course, they will give priority to the transaction. Secondly, if there is enough buying at this price, it will push up the price.
