Ticker symbols can be a bit confusing sometimes, such as when a Nasdaq company's ticker symbol ends in "F." To understand them better, know that Nasdaq stocks have four-letter ticker symbols. If there's a fifth letter, it's there to signify something. Here are the fifth letters you're most likely to see:

  • F designates a foreign company.
  • Y is for foreign stocks trading as American Depositary Receipts (ADRs).
  • E is for companies delinquent in filing reports with the Securities and Exchange Commission.
  • A and B refer to class A or B of the company's stock.
  • Q indicates that the firm is in bankruptcy proceedings.
