Insider Trading has been around since time began - people dealing on confidential information.
There have been many attempts around the world to stamp this out, but nobody has come any where near solving the problem. The nature of the problem is shrouded in secrecy and tends to be enclosed within small groups of "informed" people.
Some radicals suggest that Insider Trading should be legalised so that everything is in the open.
Insider Trading happens every day in the markets - which is why prices move on "no news".
I have not got a clue how to solve the problem - but would welcome any opinions on the subject.
