A number of studies have suggested the announcement of share repurchase programs earned positive returns. Unfortunately, general investors are limited in inferior position of information, so they are difficult to ascertain whether share repurchase program is relative to undervalued. In this instance, investors' trading direction may be misled. For this reason, we pose a R&D activity perspective to express the value information, and try to examine the role of R&D activity on following performance in share repurchase programs. In addition, in order to estimate the value with R&D expenditure, we also emphasized the importance of R&D benefit The results show the following performance of repurchase programs was significantly associated with the R&D activity, especially in R&D benefit. Relatively, long-term performance of the firms' repurchased share with worse R&D benefit decreased slightly significantly in one and half years. The experiment with Fama-French three factors model also supports above effect.
