Abstract: This research delved into the intricate relationship between exploration, exploitation, and stock price movements. Our investigation also extended to examining how firm size (an internal factor) and stock market condition (an external factor) exerted their moderating influences. Drawing from a comprehensive dataset of 15,984 firm-year observations across diverse industries, our findings unveiled a nuanced picture. Specifically, we observed a negative stock price response to exploration, contrasting with a positive response to exploitation. Interestingly, the interplay of firm size and market condition yielded significant moderation effects, highlighting the amplified positive stock price response to exploitation in the context of larger firms and favourable market returns. Further scrutiny revealed a compelling insight: firms' decisions concerning innovative initiatives were predominantly driven by their quest for long-term performance, rather than solely catering to investors' interests. As a result, our study underscores the importance of a holistic perspective, incorporating external tensions, for a comprehensive grasp of the delicate balance between exploration and exploitation.
