Real persons and legal entities residing abroad (including investment trusts and investment funds abroad) can freely purchase and sell all sorts of securities and other capital market instruments.
A foreign institutional or individual investor should use a Turkish intermediary institution for securities activities. (Such as, buying and selling securities, repo, reverse repo, portfolio management, investment consultancy, underwriting, margin trading, securities lending etc.)
Also a foreign investor can hedge currency risk by trading at ISE Derivative Market.
