Özet:

Diversified portfolios allow investors to increase their revenue without significantly increasing the risk. However, there is no generally accepted method used in portfolio diversification.  From this point to this point, this study has taken advantage of the aggregation analysis, which is one of the multi-critical decision-making methods, and one of the multi-variant statistical methods. The study has been approached from a different point of view with the foolish accumulation analysis method to the subject of portfolio creation. The study first determined the importance of the rates taken into consideration and calculated in the share capital investment with AHP and then implemented a method of accumulation analysis from accumulation analysis methods. The blurry accumulation method ensures the creation of blurry accumulations that are not accurately defined on their boundaries because it allows units to belong to more than one group. The study resulted in a set based on market-based rates (price/winning, market value/deference value and support performance), profit rates (self-source profitability, active profitability and profit per share) and risk-revenue indicators, and the set performance compared and assessed by 1, 3, 6 months and 1 year periods.
