This page shows the track record and history of KUPPUSAMY KARTHIK insider trades in Quest Diagnostics Incorporated. The SEC defines Insiders as officers, directors, or significant investors (greater than 10% ownership) in a company. It is illegal for insiders to make trades in their companies based on material, non-public information ("MNPI"). This does not mean it is illegal for them to make any trades in their own companies. However, they must report all trades to the SEC via a Form 4.
