FINRA says blogs and social networking sites are subject to your broker/dealers' supervision (in accordance with FINRA guidelines, of course). But not to worry: Today's Regulatory Notice 10-06 "does not purport to address the use by individuals of social media sites for purely personal reasons."
In short, if you want to take a picture of your breakfast and post on your deep morning thoughts on the "what's on your mind?" section of Facebook, best not to talk stocks or funds!
Because, "Social networking sites and blogs raise new regulatory challenges, particularly in the areas of supervision, advertising and books and records requirements," said FINRA Chairman and CEO Rick Ketchum. "Our goal in issuing this notice is to ensure that firms and brokers use social networking sites in an appropriate manner."
