Abstract

We examine directors’ and VC firms’ dealings before, at and after lockup expiry. Our sample encompasses 1,781 purchase and 1,115 sale transactions of the insiders in 201 UK IPOs during the period 1999-2015. Overall, directors and VC firms tend to sell and purchase in contrast to the prevailing market sentiment. The exceptions are directors’ purchases before expiry and VC firms’ sales after expiry. Director dealings, especially purchases, produce a stronger price impact than dealings of VC firms. Among insiders, dealings of founders and founder-CEOs generate the strongest price impact.
