An analysis of the performance of investment companies: evidence from the İstanbul stock exchange

Sultanov, Rustam
The purpose of this master’s thesis is to evaluate the performance of investment companies, namely Real Estate Investment Trusts (REITs) and Closed-End Funds (CEFs) in Turkey. In this study, three different models are used to evaluate the risk adjusted performances of Turkish investment companies. These models are: 1) the single-factor CAPM; 2) the Fama-French three-factor model; and 3) the Carhart’s four factor model. The results of this study indicate that for the sample period from January 1997 to December 2009, Turkish REITs and Turkish CEFs neither overperform nor underperform the overall market. Intercepts in almost all models are statistically significantly not different from zero, implying that both REITs and CEFs are earning their expected returns. The results are robust to different models used in this study. Among employed models, the Fama-French three-factor model is the best in explaining the returns on both REITs and CEFs. In general, coefficients of the size and the book-to-market equity risk factors are significant and positive. The explanatory power of the regressions does not improve with the Carhart’s four-factor model, since momentum factors have statistically insignificant coefficients in all regressions. Findings of this study have an important implication for the efficiency of the Istanbul Stock Exchange. The inability of professional money managers to beat the overall market could be taken as an evidence in favor of the ISE being either semi-strong or strong form efficient. On the other hand, lack of skills on the part of Turkish fund managers might be another explanation for their inability to surpass the performance of the overall market.

It is found that, depending on the affiliation of the insider with the company, abnormal returns from their sale transactions last over longer periods than their purchase transactions. Furthermore, outsiders can also earn abn...

An Application of the Black Litterman model in Borsa İstanbul using analysts’ forecasts as views
Adaş, Cansu; Güner, Zehra Nuray; Danışoğlu, Seza; Department of Financial Mathematics (2016)
The optimal number of stocks to include in a portfolio in order to achieve the maximum diversification benefit has been one of the issues in which investors have focused on since Markowitz introduced fundamentals of the Modern Portfolio Theory. Each stock included in an investor's portfolio decreases the portfolio risk, while increasing the transaction costs incurred by the investor to create this portfolio. In this thesis, the size of a well-diversified portfolio consisting of stocks included consistently ...
