Stochastic portfolio theory is a novel methodology, developed by Fernholz (2002), for analysing stock and portfolio behaviour, and equity market structure, constructing portfolios and understanding the structure of equity markets. It thus has immediate applications to equity portfolio management and performance measurement. This theory successfully generalises well-known models for the stock price to provide models for portfolios and markets, leading to a better and more precise understanding of equity market structure. The aim of this dissertation is to present an exhaustive review of stochastic portfolio theory by imitating the work done and contributions made by Fernholz (2002) thus far. A detailed discussion of stochastic portfolio theory as well as how the implications di er from the conclusions and results of classic portfolio theory will be provided. In this dissertation, we will undertake a thorough investigation into stochastic portfolio theory; by focusing on the central, innovative ideas of the excess growth rate, long-term stock market and portfolio behaviour, stock market diversity of equity markets, portfolio generating functions, the concept of how to select stocks by their rank and the existence of relative arbitrage opportunities within the context of stochastic portfolio theory. Thus, we shall review the central concepts of stochastic portfolio theory, this will include a detailed explanation of the excess growth rate, long-term behaviour of portfolios, stock market diversity, portfolio generating functions and stocks selected by rank. We will also present examples of portfolios and markets with a wide variety of di erent properties. We will also show how this new and fast-evolving theory can be applied, in particular, to equity management, by considering the performance of certain functionally generated portfolios. Furthermore, several results and implications of stochastic portfolio theory will be discussed, and in this dissertation, we shall examine these results in far greater depth. Keywords and Phrases: Stochastic portfolio theory, Portfolios, Stock market and portfolio behaviour, Stock market diversity, Portfolio generating functions, Functionally generated portfolios, Rank-dependent portfolio generating functions, Local time, Relative arbitrage opportunities, Performance of functionally generated portfolios.

Based on a long span database, four important issues are addressed in this study. First one is about their holding preference in Taiwan stock market. The second and third issues are relative to the positive feedback trading and herding. Finally, the price impact of their trading behavior is also discussed on various angles. / In sum, the empirical results of this study suggest the success of the QFIIs scheme in Taiwan, and the import role played by the foreign institutional investors for this success. However it should be noted that the trading behaviors of the foreign investors in the emerging market has a close relationship with the nature and characteristics of the industry and economy of this country, especially the internationalization levels of the domestic industry and the opening degree of the national economy. / Part I. This study provides an integrate investigation into the trading behaviors and the price impact of the qualified foreign institutional investors (QFIIs) in Taiwan stock market. The main purpose of this study is to provide some policy implications to the regulators of emerging financial markets by giving a comprehensive insight into the whole development process of QFIIs scheme in Taiwan. Another purpose is to contribute to the literature, especially on the emerging market, with extensive and in-depth evidences of the QFIIs a sub-group of institutional investors. / Part II. A populous viewpoint ascribes the resent stagnancy in the Chinese stock market to the original inequality of the equity price and rights between the non-liquid equity holders and liquid equity holders. Using the Capital cost IRR method, this paper provides another view on this problem by analyzing the interest balance between the two types of equity holders in the Chinese listed companies. The theoretical models and empirical results suggest the two types of equity holders can reach their interest balance under the original of stock market system, though the balancing mechanism is skewed and results in a wealth outflow due to the specific equity structure and agency problem of the Chinese listed companies. As the necessary step for the long-term development of the Chinese stock market, "Full liquidity" may lead to the break down of the original balance mechanism. Some problems results from the skew mechanism may float up in the new balance achievement and put some pressure to the market. The key to the market reform is not making any compensation to any type of the equity holders but lies in how to restrict a new balance system and mitigate the market pressure.
