The won’s recent rally could gather momentum as Samsung Electronics and SK hynix pursue record shareholder returns expected to trigger billions of dollars in currency conversions. Earlier this month, the won moved into the 1,300-per-dollar range for the first time since October. Although it has traded around 1,370 to 1,380 per dollar in recent sessions, analysts said the currency could strengthen further as the companies’ large shareholder-return initiatives support demand for the won.
