Abstract
The maximum entropy principle is a fundamental principle in statistical physics. The principle is used to study the distribution law of asset prices in financial markets, and it is concluded that the maximum entropy distribution of asset prices follows a lognormal distribution. The daily data of four typical stock price indices, namely the Shanghai Securities Composite Index, Shenzhen Component Index, Hang Seng Index, and Shanghai Shenzhen 300 Index, are selected as empirical data, and MATLAB is used for programming. By comparing the actual frequency distribution curve with the theoretical frequency distribution curve, the logarithmic normal distribution law of asset prices is verified. It is shown that the logarithmic normal distribution can be used to fit the actual asset price distribution, and the maximum entropy principle is also suitable for studying the distribution law of asset prices.
