A security (e.g., a stock) that meets the requirements of an exchange for being traded (purchased) on margin (margin trading). For margin trading, customers to a brokerage can borrow up to a specific percentage (e.g., 70%) of the market value of these securities. However, not all securities are marginable. Marginability is subject to a specific set of conditions such as a minimum price (stocks trading at below $5 are not marginable), venue (usually organized exchanges, but not stocks trading on pink sheets), and stocks of companies that have newly gone public.
