InsiderDennis Cho
This page shows the track record and history of Cho Dennis insider trades in Twist Bioscience Corporation. 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.
