The study investigated the investment strategy of the Temasek Holdings as one of the most successful SWFs which is owned by the government of Singapore. Temasek Holdings was founded in 1974 to manage part of the government＇s revenues. Present turbulent times create a big pressure on healthy investment strategy of the SWFs. But total shareholder return for Temasek since its inception in 1974 has been a healthy 17% compounded annually. The main objective of the paper is to focus on the role of the Temasek Holdings as a company managed on commercial principles with an aim to achieve long-term sustainable returns. The study also analyzed Temasek Holdings＇investment strategy. The study provides answers to questions like： why Temasek is of the most successful SWFs and what is the fund risk management？ Another part of the paper compares investment strategy of the Temasek Holdings with other SWFs. The study has been conducted mainly on the basis of literature survey, secondary information and with using various web sites and research paper. The analysis has been also based on disclosures appearing in the Temasek annual reports over the period from 2008 to 2010.展开更多

For that purpose, the investment funds are very important tools to create a portfolio for small investors, to deploy the potential risks in optimal proportions, and to direct investors. In this study, the performance of 83 pieces of investment funds will be evaluated which are treated in Turkey dates from January 1, 2010 to December 31, 2012 with performance evaluation methods such as Sharpe, Modigliani （M2） that is based on the standard deviation, and Treynor, T2, Jensen that is based on systematic risk （beta）, and the highest and lowest performance investment funds will be presented. The aim of the study is to examine the success of the investment fund managers whether they could estimate the course of the market well or not regarding time period. The empirical results show that the investors who invest on the funds that have negative risk premium by investing in the investment funds getting under the risk cannot get more excess return than getting the return from the risk-free interest rate as treasury bills. The result implies that it could be said that the systematic and total risks of all investment funds are low and they are not sensitive to the developments in the market, and thus, regarding funds could be called as conservative funds.展开更多

There are different society and disagreements as to whether wealth maximization should be the sole goal of a corporation. There is also a debate on whether CSR practices are beneficial for firms. Studies examining the performance of firms that have adopted a CSR policy within a range of sectors in various countries provide inconsistent results. Some studies show excess returns among companies adopting a CSR policy relative to the companies that do not adopt such a policy, while others do not find differences in returns. To further dispel the ambiguity on this issue, the authors explore the relationship between CSR adoption and financial performance of firms＇ shares in Israeli market, with a US market benchmark as a test of specificity. The findings reveal that no significant difference exists between the performance of firms adopting a CSR policy and firms that do not. Thus, the inclusion of investments in socially-responsible firms in an investor＇s portfolio does not appear to significantly impact the portfolio＇s performance. Managers and investors interested in investing in CSR may do so without any concern of the lower returns or performance. This study provides an additional support for the CSR School in that its findings indicate that, on the one hand, investments in firms that integrate social and environmental responsibility are just ＂as good as＂ investments in firms that do not. On the other hand, such investments can be seen as superior, since in addition to the financial returns, investors contribute to changing the face of the global environment and are creating a system for support and enforcement that ensures the existence of a better world for the children in the present and future.展开更多

However, the effect of loT on economic growth has not been fully explored. This paper analyzes this issue from the perspective of ICT investment. After analyzing the data of eight representative provinces from 1996 to 2008, we f＇md out that the effect of ICT investment on e- conomic growth is limited and the levels of telecom- munications infrastructure and education are key factors influencing the effect. Thus it＇s necessary to further improve the telecommunications infrastructure and enhance related education and training to promote the effect of loT on economic growth.展开更多
