This thesis consists of four essays on the topic of asset management. The first essay, Performance and Characteristics of Swedish Mutual Funds studies the relation between fund performance and fund attributes in the Swedish market. The results show, among other things, that good performance is to be found among small equity funds, low-fee funds, funds whose trading activity is high, and in some cases, funds with good past performance. The second essay, Does Active Trading Create Value? An Evaluation of Fund Managers' Decisions decomposes fund performance and examines how it is influenced by fund managers' strategic and tactical decisions. The results support the value of active portfolio management in Sweden. The essay also finds a positive relation between performance and fund managers' voluntary trading decisions. In contrast, there is some evidence of inferior trading decisions when fund managers are forced to trade. The third essay, Investment Strategies, Fund Performance, and Portfolio Characteristics analyzes the relation between fund performance and fund managers' investment strategies. The results show that neither momentum characteristics nor the valuation of stocks in the fund portfolio can explain differences in fund performance. The findings also show a positive relation between performance and the degree of diversification of the fund portfolio. The last essay, Costly Information, Diversification, and International Mutual Fund Performance examines how fund managers' costly search for information affects the performance of mutual funds that invest in Asia and Europe. The essay shows that fund managers who select from a smaller set of Asian stocks perform better than those who select from a larger set. Moreover, the performance of large international mutual fund companies is similar to that of their small competitors. This suggests that there are no economies of scale in the costly search for information. / Diss. Stockholm : Handelshögskolan, 2001
