Detailed Quantitative Explanation
Enacted in April 2012, the STOCK Act affirmed that members of Congress, judicial officers, and executive branch officials are subject to insider trading prohibitions under the Securities Exchange Act of 1934.
The law requires lawmakers to file Periodic Transaction Reports (PTRs) within 30 to 45 days of any securities transaction exceeding $1,000 made by themselves, their spouses, or dependent children.
While intended to deter conflicts of interest, delays in filing and modest late-filing fines ($200) have led to persistent late disclosures, providing critical forensic signals for retail market observers.
