Stronger Enforcement of Civil Penalties Act of 2017 This bill amends the Securities Act of 1933, the Securities Exchange Act of 1934, the Investment Company Act of 1940, and the Investment Advisers Act of 1940 to increase civil and administrative monetary penalties for securities laws violations. The bill also adds a fourth tier of monetary penalties for violations by a person that, within the five-year period preceding the violation: (1) was criminally convicted for securities fraud; or (2) became subject to a judgment or order imposing monetary, equitable, or administrative relief in a Securities and Exchange Commission (SEC) action alleging fraud. In addition, the bill expands penalties for violations of certain federal court injunctions or SEC orders.
