SEC approves securities arbitration fraud intervention rule. The U.S. Securities and Exchange Commission has approved a rule that will let securities arbitrators immediately report frauds that may threaten the investing public if they learn about them in the middle of a case. The agency’s approval, published in the Federal Register on Wednesday, ends years of controversy about the proposal, which was sparked by multibillion-dollar Ponzi schemes orchestrated by Bernard Madoff and R. Allen Stanford. More on Reuters here.
