Whether and when do alliance terminations pay off?

Engaging in multiple strategic alliances, a firm forms an alliance portfolio. While a larger alliance portfolio signals investors a firm's ability to exploit new opportunities and improve financial performance, having multiple alliances may also undermine financial performance due to a firm's limited ability to effectively manage these alliances. Announcing an alliance termination, a firm signals an intention to increase the effectiveness of a larger alliance portfolio. This article examines the extent to which alliance termination announcements create value for firms with multiple alliances. Building on the resource-based view of the firm and organizational learning literature, the paper hypothesizes a U-shaped relationship between alliance portfolio size and a firm's cumulative abnormal stock return following an alliance termination announcement. This effect is moderated by the amount of a firm's alternative resources and partner-specific experience that affect its ability to effectively manage multiple alliances. The results show that alliance termination announcements create firm value when an alliance portfolio is large.
