In stock market of Taiwan, stocks with the highest market value and the highest stock price of each industry often are regarded as first choice by government fund and ordinary investors. In this research, we utilize the deadline of quarterly financial reporting to construct two different models of portfolios: the highest market value vs. the highest stock price. Moreover, we will evaluate the performance of two portfolios and compare the two portfolios with the rate-of-return on domestic open-ended mutual funds and weighted stock price index. Besides, we must assess the phenomenon mentioned above is reasonable or not . In the end, for the sake of providing a valuable investment strategy to retail investors, contrast to institutional portfolios, we also establish retail portfolios, The main empirical findings as below：
1. Generalized investment portfolios
After comparing with the rate-of-return on weighted stock price index, in terms of beating the market, we verify the performance of the highest market value portfolio is better; however, on the part of defeating domestic open-ended mutual funds, the highest market value portfolio is worse.
By comparing with the market and domestic open-ended mutual funds, we also discover the performance of the highest market value portfolio is better than its counterpart.
(3)Institutional portfolio V.S. retail portfolio
After we sort performance of institutional portfolio and individual portfolio, no matter we utilize relative performance or absolute performance as benchmarks. It is apparent that in the point of the highest market value type, its retail portfolio has preferable performance. Nevertheless, the outcome of the highest market price portfolio is totally opposite.
2. Fundization portfolio
After summarize the number of fluidization portfolio’s performance which ranking in the top 20%. The highest market value portfolio is a relatively better choice.
By surveying performance of the two fundization portfolio, the highest market value portfolio shows mediocre rate-of-return. Besides, contrast to the highest market value portfolio, the highest market price portfolio presents extremely awful rate-of-return. It is obviously that if the government tries to hold the stock price index, the traditional strategy which government adopted is to buy the highest market value and highest market price stocks. Our empirical result of showing a poor rate-of-return is not surprised.
