In an interesting two-part column series in the Mint (here and here), Govind Sankaranarayanan considers the broad academic debate surrounding insider trading. He makes at least two pertinent observations: (i) the line between insider trading that is considered acceptable and that which is improper is quite often blurred and difficult for regulators to segregate; and (ii) there is a need for regulators to undertake greater investigations and enforcements, which may not only act as greater deterrence but may also help set some boundaries between the permissible and the proscribed.
