In addition, acquirers tend to use stock payment when they are not confident about synergy with target firms (Schijven & Hitt, 2012). If firms rush into M&As in the presence of high CEO-CFO LSM, such M&As will likely be paid with a lower (higher) percentage of cash (stock). Meanwhile, investors react positively to deals paid with a high percentage of cash because such deals are associated with low risk and have a higher chance of success (Hansen,1987; Martin, 1996). Thus, CEO-CFO LSM may be negatively associated with investor reactions to M&A announcements, and such an association is mediated by payment methods.
