The result shows that Thai property funds' behavior is exposed to corporate bond (60%), medium-capitalization stock (21%) and small-capitalization stock (10%). However, the analysis also indicates that the equally weighted property fund portfolio is made up of style component by only 47%. There exists a unique characteristic of property funds which could not be found from other asset classes. The existence of property funds allows investors to further eliminate diversifiable risk in their portfolio.Index Terms-Equally weighted property fund portfolio, large-capitalization value socks, large-capitalization growth stocks, medium-capitalization stocks.
