The SEC asked for its biggest budget in 50 years.

The Securities and Exchange Commission said it would use the additional funds to escalate the war against insider trading and other securities fraud. The Reagan Administration has requested $145 million for the SEC in fiscal 1988, and SEC Executive Director George Kundell said that if Congress agrees to the $30.5-million increase, the agency could add staff and resources in enforcement operations, regional offices and in the EDGAR program--the computerized project designed to automate filing, processing and dissemination of documents filed with the agency.
