Portfolio management is deciding when securities are removed and when securities will be added. Traditional portfolio theory ignores the relationship between mutual funds and quantitative data. This is done by Modern Portfolio Theory, which uses the mathematical and statistical methods in the second half of the 20th century. Undoubtedly, market analysis within the scope of this theory will provide great convenience to investors.
