Insider Trading Prosecutions In The Uk
🔍 Insider Trading in the UK — Overview
Insider trading involves trading shares or securities based on “inside information” — confidential, price-sensitive info not available to the public.
It’s prohibited under the Criminal Justice Act 1993 (Part V) and the Financial Services and Markets Act 2000 (FSMA).
It harms market integrity by giving unfair advantage and undermines investor confidence.
To prosecute, authorities need to prove:
The defendant had inside information.
They used or disclosed that information for trading.
The information was not publicly available and price-sensitive.
