Vistra Insiders Sold US$29m in Stock, Raising Concerns of Potential Weakness.

Over the past year, Vistra Corp. insiders have sold $29m worth of stock, with the Independent Chairman of the Board, Scott Helm, making the largest single transaction worth $8.6m. While insider selling can be open to interpretation, this could be a red flag for investors. The silver lining is that the sales took place at a higher price than the latest market price.
