This would be a stock quote from Over-the-counter (OTC) trading rather than NASDAQ or NYSE. For example, NSRGY is in Pink Sheets. You can get a quote for NSRGY.PK in AOL Finance. DDAIF.PK is also available, and RHHBY.PK. But NZTCY is not available. You may have to find a website like otcmarkets.com or esignal.com to track the ones not in Pink Sheets.
