Reading NASDAQ Ticker Symbols
Blueprint For Financial Prosperity presents a handy little list of possible fifth letters in NASDAQ ticker symbols and their respective meanings. All NASDAQ stocks are identified by a unique four letter code. If there is a fifth letter, it denotes some information regarding the issue or the issuer (e.g., the letter "K" denotes the issue is a non-voting share, the letter "E" denotes the issuer is delinquent in required SEC filings).
