When to take investing advice from Twitter - Chuck Jaffe - MarketWatch: "This month, the U.S. Securities and Exchange Commission updated the filing requirements for many social-media communications. Without these updates, most compliance officers held one basic tenet with regard to most social-media activity, namely that every statement a firm or money manager makes about investing must be treated as if it were a material disclosure, with the information filed with regulators. The Financial Industry Regulatory Authority, or Finra, the brokerage industry’s private self-regulator, basically has that standard too."
