Owning it from abroad

Samsung SDI has no US-listed ADR and its Luxembourg GDRs (SMSDI, 4 GDRs = 1 share) belong to a restricted programme with very thin trading, so most investors abroad buy the KRX shares (006400 common or 006405 preferred) through a broker with Korea market access, or get indirect exposure through Korea-focused ETFs such as EWY (check a fund's current holdings).
