We create a novel measure of market-nurtured optimism in that managers become more optimistic if the market had responded more favorably, and to a larger extent to positive earnings surprises, than to negative earnings surprises. These market-nurtured managers are prone to engage in value-destructive mergers. The inclination is further reinforced by abundant internal cash. In contrast, a good governance structure mitigates the odds of engaging in mergers and the detrimental effect associated with mergers. The acquisitions launched by overconfident managers are associated with lower market value.
