Insider dealing provokes many discussions. The common knowledge about this
behaviour is that one may become rich thanks to a single transaction on a stock
market. Such a perspective does not leave anyone indifferent; whether it be the
expression of condemnation for such behaviour or an unspoken dream about
becoming a well informed insider one day. Although many national systems
prohibit insider dealing,1 its character and potential wrongfulness are still discussed
by economists, ethicists and lawyers. Definitely not all of them share the opinion,
expressed by many national legislations, that insider dealing is unfair, wrongful, or
harmful for the economy as well as for individual market players. Nonetheless, it
may be observed that as the new insider dealing regulations were enacted, the
prohibition has been enforced by application of increasingly severe penalties,
including the use of criminal sanctions. A question may, however, be raised on
whether criminal law is a right tool to deal with the issue.
