I've been CFO of two publicly traded companies and reg FD has teeth. It prohibits an officer of a listed company from providing info to one party before another. I can't call my buddies during a quiet period after a Q ends and before we report earnings and tell them "hey, we're trading at $30 a share now, things look good and you should load up", nor should I be able to.
.gov moves markets with their actions. There is a law against congress critters using intelligence briefings and such to make investment decisions because they get early mover advantage before you and I know what the fuck is going on. Think about it.
