The study is based on “Value Investing” by Graham. Greenblatt combined Graham and Buffett’s investing method, and designed a magic formula, including “Return on Capital” and “Earning Yield”. We desire to know which portfolio of the three famous investors would beat the market index in Taiwan stock market. The empirical results are as follows: 1. The result shows that if the stock is held for a period, except for Graham’s first holding year, the rate of return of all of the three investors’ portfolios are better than the market. Therefore, the value investment method applies to Taiwan stock market. In addition, if the stock is held for three and five years, magic formula portfolio by Greenblatt has a better rate of return. From the investment of Graham, we can know that the longer you hold the stock, the higher the return. This shows that value investment is suitable for longer holding period than short-term trading. 2. As for the volatility of portfolio, Greenblatt’s investment method is steadier and safer. 3. Regarding types of industry, the three famous investors prefer building materials and construction industry, and electronic components manufacturing industry.
