In the recent years, some scholars suggest the portfolio theory within technology investment into Technology Portfolio. This article examines the impact of different portfolio strategies with Modified Sharpe Index to examine the values of internal/external technologies investment of companies. Moreover, we surveyed and arranged those research models from journal papers involved technology portfolio to illustrate the paths that technology portfolio theories developed. Innovative approach of valuing intellectual property is proposed to estimate how technology portfolios may influence product values. Accordingly, technology portfolio strategies of companies can be utilized to identify the standards of product pricing, as well as to improve its sales volume or numbers with appropriate promotion. In this study, the technology portfolio is evaluated by suggested Modified-Sharpe-Index (MSI) function. Portfolio theory in financial is adopted with the concepts of technology development, which also combines the value of tangible and intangible assets along with risk and strategic factors, to evaluate the performance of a technology portfolio.
