LS, Samsung SDI and LG Electronics were the three most heavily purchased stocks through 11 a.m. on July 1 by Mirae Asset Securities clients ranked in the top 1% for investment returns over the past month. LS shares fell more than 2% into the low 300,000-won range, about half their late-May peak of 604,000 won, but attracted buyers on record subsidiary orders and expectations that rising electricity demand from artificial intelligence infrastructure will benefit its power-equipment and cable businesses. LS Cable & System reported a first-half order backlog of 7.8336 trillion won, while LS ELECTRIC and LS Cable & System together account for 71% of LS’s corporate value, according to securities analysts. Samsung SDI ranked second after gaining roughly 60% over the past month, supported by its planned sale of 5% of its Samsung Display stake and expectations for a wholly owned North American energy-storage battery operation. LG Electronics ranked third amid Morgan Stanley’s view that the company could benefit from growth in AI Home, robotics, commercial HVAC and data-center cooling. Samsung Electronics later entered the net-buying list on expectations that its HBM4 competitiveness is recovering. SK hynix was the most heavily sold stock despite extending its rally, while Samsung Electro-Mechanics and Alteogen also ranked among the leading net sells.
