Stocks are easily manipulated by institutions, especially in China stock market. Due to the obvious gap between institutions and ordinary investors in terms of professional ability, information channels and financial strength, and the lack of supervision by regulatory agencies and the lack of standards for punishment, it is still an era of stock flooding. This phenomenon is much less in mature stock markets in Europe and America, because the punishment is very severe.

Foreign exchange mainly depends on the changes of political and economic situation in various countries, and it is an extremely huge market. It is the country that can manipulate the exchange rate. For example, the loose monetary policy in the United States has led to the continuous weakening of the US dollar exchange rate, which has put other countries, including China, under the pressure of imported inflation. However, for some capital predators, it also happens from time to time to attack the currencies of some small countries for profit. For example, 1997 Soros attacked the Thai baht, which caused the Thai baht exchange rate to plummet.

At present, fair competition in the domestic market is only aimed at investors at the same level, and retail investors still have great advantages over retail investors and institutions, especially information channels.

Hidden rules are very common in China's financial industry, and many behind-the-scenes tricks are actually open secrets, which are well known, but most of them have no evidence.
