The smartphone parts theme covers Korean listed companies that manufacture components used in mobile phones, such as camera modules, flexible printed circuit boards, display-related parts, batteries, and connectors. Korean investors often group these firms together because their revenue tends to move with global smartphone shipments and with the launch cycles of major handset makers. Their fortunes are also linked to supply chains that include both domestic and overseas device brands.
