The analysis of multi-fractal structure of stock markets on the basis of MF-DFA

Fractal theory is one of important branches of modern nonlinear science, whose development provides economics research with a new tool. Based on Fractal theory, the paper chooses the profit data from stock market and uses MF-DFA to study fractal property. It is found that stock market has obvious Multi-fractal characteristics. Furthermore, it is also found the significant difference between developed country´s mature stock markets and developing country´s emerging stock markets.
