What is insider trading?

Introduction to Insider Trading

QUICK DEFINITION: Insider trading is trading based on material non-public information.

While certain legal elements required for insider trading liability have been unsettled recently, the pattern of trading required to flag potential insider trading remains straightforward. If a trader acquires a significant position within a short time prior to a news event that materially benefits that position, the trader may have been trading based on material non-public information and the trade should be flagged for further inquiry.
