Also, which shareholders? Shareholders have no say in the business decisions outside of the annual voting for board members and whatever broad issues are brought up for a vote. If someone holds stock and then sells it before a vote, are they responsible for the business decisions? If a swing trader bought and then sold in one day/week/month (even at a loss), how much is their liability? If someone sells their shares just before a vote, then buys them again after, are they liable?
