analysis of financial markets of selected countries: an approach to quantum mechanics in economics

The stock market of any country plays an effective role in attracting financial resources and contributing to the development of that country. the stock market also has a significant importance in economic recession and prosperity, which are affected by national macro policies. effective political decisions made by politicians can lead to the attraction of significantly more capital. thus, analyzing the stock market using an accurate analytical system is essential. following alves et al.’s (2020) study that examined the stock market efficiency index of different countries, the present study selected and compared the stock markets in iran, germany, england, brazil, turkey, russia, japan, switzerland, saudi arabia, south korea, and india based on the daily data of the stock markets from 2013 to 2023. using schrödinger’s equation and hamilton’s expansion, the present study adopted the financial quantum approach to solve the wave function and draw and compare the distribution and average rate of return diagrams. the data from the stock markets of the selected countries indicated the highest fluctuations but less efficiency in the turkish stock market, while the lowest range of fluctuations and higher efficiency were found in the british stock market. moreover, the british stock market has the minimum average rate of return, the minimum risk, and the maximum transparency, while the turkish stock market has the maximum average rate of return, the highest risk, and the lowest transparency.
