OTC-BB (Over The Counter Bulletin Board): A regulated quotation service that displays real-time quotes, last-sale prices, and volume information in over-the-counter (OTC) equity securities. An OTC-BB equity security generally is any equity that is not listed or traded on NASDAQ or a national securities exchange. OTC-BB securities include national, regional, and foreign equity issues, warrants, units, American Depository Receipts (ADRs), and Direct Participation Programs (DPPs). In other words, it is a system for creating some regulation and accountability for stocks "without a home." There are many great penny stocks that are listed on the OTC-BB (and many not-so-great too). You can review our full explanation of OTC-BB stocks in our section, Where Do Penny Stocks Trade?
