Reasons for A-share crash:

Economic reasons, such as unsatisfactory economic development, will directly lead to low desire for investment. After all, everyone is afraid of losing money. If less money is invested in the stock market, the stock price will fall.

when entering a bear market, the bull market and the bear market rotate with each other. After the bull market, it will follow the bear market. Everyone can't tell why it fell. Anyway, opening the stock market every day is green.

The bad news, such as the change of the Federal Reserve's interest rate, still has a great impact on China, and it is hyped several times every year, but in fact, most of them are groundless.

the influence of the international stock market, although the stock markets among countries are relatively independent, is not absolute, and every time the international stock market plummets, A shares are hard to escape.

policy factors, major events at home and abroad, and major events such as government policies, measures and decrees, the government's socio-economic development plan, changes in economic policies, newly promulgated decrees and management regulations will all affect the changes in stock prices.

The rise in commodity prices has brought about serious inflation expectations, which has caused the market to worry about the economic recession, and the outbreak of panic has led to a decline in the share prices of many people who sell stocks.

As a result of the war, people all over the world were in a panic after the start of the international war. As a result, people's sentiment of investing in stocks was dampened, and they sold stocks and funds instead to buy gold.

The reasons for the A-share crash need to be discussed according to the facts. After all, the reasons for the crash in each stage are different. Except for the impact of the bear market, the crashes in other time periods are mostly related to the news.

A-shares, that is, ordinary shares in RMB, are ordinary shares issued by companies registered in China, listed in China, and denominated in RMB for domestic institutions, organizations or individuals (Hong Kong, Macao and Taiwan residents can open A-share accounts from April 1, 213) to subscribe and trade in RMB.

the English letter a has no practical significance, but is only used to distinguish ordinary RMB stocks from special RMB stocks.

A-shares are not physical stocks, and they are accounted for electronically without paper, and the "T+1" delivery system is implemented, with price limit (1%). The participating investors are Chinese mainland institutions or individuals. The stocks of listed companies in China include A shares, B shares, H shares, N shares and S shares.
