在足够长的时间内，股价不会处于一个持续向上或向下的通道，最终会回归均值

In a long enough time, the stock price will not be in a continuous upward or downward channel, and will eventually return to the mean range. The traditional mean regression theory generally exists in the research of the stock market, revealing the operation law of the price of a single asset, and the new research applies the mean regression theory to two related assets. Return to law. The mean regression theory is applied to a variety of asset arbitrage, emphasizing the relationship between the rate of return on related assets: if the rate of return on improper assets is equal, no matter what assets are invested, there is no difference; if the rate of return on some assets is higher than other assets , Investors will choose assets with higher yields, and capital will flow from products with lower yields to assets with higher yields. Such a mechanism will cause the returns of different assets to return to the same level. The mean regression theory promotes the rational regression of the non-equilibrium market and returns the spread relationship to a reasonable range and range. This theory is also the theoretical basis of cross-variety arbitrage.

For long enough, the share price will not be in a continuous upward or downward channel and will eventually return to the mean range. The traditional mean regression theory is widespread in the study of stock market, which reveals the operating law of single asset price, while the new research applies the mean regression theory to two related assets, and the relationship between the different asset yields follows the law of mean regression. The theory of mean regression, which applies to multiple asset arbitrage, emphasizes the relationship between the return on the underlying assets: if the yield on improper assets is equal, no matter what assets are invested, there is no difference; The theory of mean regression promotes the rational regression of the unbalanced market and returns the spread relationship to a reasonable range and range, which is also the theoretical basis of cross-variety arbitrage.

For a long time, the stock price will not be in a continuous upward or downward channel, and will eventually return to the mean range. The traditional mean regression theory generally exists in the research of stock market, which reveals the operation law of single asset price. In the new research, the mean regression theory is applied to two kinds of related assets, and the relationship between different asset returns also follows the mean regression law. Mean regression theory is applied to a variety of asset arbitrage, emphasizing the relationship between the return of related assets: if the return of improper assets is equal, no matter what asset is invested, there is no difference; If the rate of return of some assets is higher than that of other assets, investors will choose the assets with higher rate of return, and the capital will flow from the products with lower rate of return to the assets with higher rate of return. Such a mechanism will make the rate of return of different assets return to the same level.
