Index Tracking and Enhanced Indexing Using Co-integration and Correlation Approaches

Index tracking is a passive investment which its aim is to form portfolio with limited number of stocks to catch same behavior in regard with the market index. The active portfolio management seeks to beat the market while passive portfolio management is looking for the similar risk-return pattern with market index. The passive portfolio management strictly has absorbed attention of investors because of its lower costs. In this research, cointegration and correlation approach are used for index tracking and enhanced indexing. Our benchmark index is Tehran Exchange Dividend & Price Index (TEDPIX). Out of sample results show that increase of in-sample time period will improve performance of models. Also, mentioning tracking error, cointegration approach has better performance than correlation approach. In the other hand, considering portfolio returns and information and sharp ratios, performance of model for index tracking is better than enhanced indexing.
