There are two markets for trading stocks on the ISE namely, the Stock Market and the Emerging Companies Market (ECM).  Companies that fulfill the listing requirements or relevant market criteria determined by the ISE can be traded on the Stock Market. The securities of companies that do not meet the listing requirements of the ISE, but promise a development and growth potential can be traded on the ECM.

To be eligible for being traded on the ISE markets, the stocks which have been registered with the CMB and offered to public should be listed on or registered with the ISE or admitted to the ECM Directory.

ISE listing/registration and admission to ECM Directory allows stocks offered to public to be traded on the first and the only stock exchange of Turkey.
 
Trading on the stock exchange is the purchase and sale of stocks by investors on the secondary markets.  Being traded  on the stock exchange provides liquidity for company shares, and creates long-term and inexpensive financing opportunities for the companies. The listing or admission to ECM Directory of stocks on the stock exchange provides companies with creditworthiness, institutionalization, recognition, and improves integration of the company with national and international markets.  
 
Listing (listing on the ISE) is the acceptance of registration with the respective market of the stocks which are requested to be continually traded on the securities exchanges provided that they meet the respective terms (listing criteria).

Initial listing is the first-time listing of a stock on the stock exchange.  Additional listing means the listing of newly issued stocks due to capital increase of a company whose stocks have already been listed.

Stocks representing partnership rights, bills-bonds granting creditor rights and Other Capital Market Instruments which are considered as securities by CMB can be listed and traded on the ISE.
