Yes, so long as the regulation complies with the statutory grant of authority that Congress gave to the SEC. Unfortunately, that statutory grant of authority came in the Securities Exchange Act of 1934, which was passed by Congress in the aftermath of the Great Depression, which was caused by the Wall Street Crash of 1929. Facing political pressure to prevent another Great Depression, Congress gave the SEC extremely broad mandates to regulate markets and protect investors. Almost any regulation that the SEC can think of can be made to fall within one of those concerns, giving the SEC an extremely broad regulatory authority.
