Strategic management of technological resources plays a significant role in the success of firms in today’s economic environment. This paper studied the relationships among selected technology strategy dimensions and perceived performance of firms, which went public at KOSDAQ. Using content analysis, technology strategy data were collected from the prospectus of 40 firms that committed IPOs in 2000. Empirical analysis shows support for propositions that a firm’s technology portfolio and R&D spending influence investors’ reactions to IPOs. The many products in technology portfolio has a negative impact on IPO performance, and the high ratio of R&D spending over sales has a positive impact on IPO performance.
