The STOCK Act was passed to address the issue of insider trading by members of Congress, but it didn't actually change any laws. Insider trading laws are unclear, making it hard to prosecute Congress members for trading on nonpublic information. The Act only sheds light on the relationship between Congress members and the source of the information, but doesn't solve the legal problem. Despite suspicions, no Congress member has been charged with insider trading. The Act may unintentionally support a controversial SEC regulation for others.
