This paper attempts to explore the insider trading behavior before joint venture announcements and the post announcements of parent firm performance. Because information asymmetry can be much stronger when investments are across borders in international joint ventures. This paper also wants to test if the effect of insider trading can have more important suggestive effect on the post- performance in international joint ventures. Furthermore, the opportunistic behaviors from partners in different industries are more difficult to detect because a firm may not be familiar with the business practices of partnering firms. When information asymmetry becomes a great concern, the information conveyed from managers and officers can be more value relevant. Insiders trading may convey greater signaling effect on their value assessment for the joint ventures. The purpose of this paper is to investigate if corporate insiders, such as managers and officers, are able to systematically predict the value creation of joint ventures. And the results indicate that insiders will not increase net purchases before the joint venture event, regardless of foreign partners or dissimilar industries partners. The contribution of this paper is to analyze the insider's trading behavior before the joint venture event and provide suggestions for future research directions.
