The stocks most heavily bought by high-return investors trading through Mirae Asset Securities on the morning of the 28th were Samsung Electronics, Samsung Electronics preferred shares, LG Innotek and Samsung Electro-Mechanics, in that order.
According to Mirae Asset Securities, Samsung Electronics was the most purchased stock through 11 a.m. among "top-tier stock traders" — the brokerage's clients whose investment returns ranked in the top 1% over the past month.
Samsung Electronics was trading at 273,000 won as of 11:39 a.m., down 4.38% from the previous session, according to the Korea Exchange. The share price has been falling as selling pressure builds amid mounting uncertainty, including a prolonged war, high oil prices and high interest rates. Some investors appear to have viewed the decline as a buying opportunity and moved in aggressively. The top-performing investors made Samsung Electronics preferred shares their second-largest net purchase that morning.
Samsung Electronics is expected to accelerate earnings growth by expanding its share of the high-bandwidth memory (HBM) market and stabilizing foundry yields. In a report released this month, KB Securities projected that Samsung's fourth-quarter HBM market share would approach 40%, up about 7 percentage points from 33% in the second quarter. The brokerage said the strategic growth opportunity in the HBM business has widened as the company ramps up HBM4 mass production and supplies HBM4E samples to major customers, while also holding various options including a strategic partnership with TSMC.
Improving competitiveness in the foundry business and expanded shareholder returns are also anticipated. Samsung Foundry has stabilized its 4-nanometer production yield above 80%, and its 2-nanometer GAA yield has risen above 70%, restoring mass-production competitiveness in advanced processes. With steep growth continuing in its core business and additional shareholder returns expected this year — including share buybacks, cancellations and cash dividends — many analysts see ample room for the stock to rise. KB Securities maintained a "buy" rating with a target price of 600,000 won.
LG Innotek, ranked third, was trading at 577,000 won, up 7.85%. Shares of LG Group affiliates have risen together after LG Electronics was named an official partner of Nvidia in the power and cooling segment for artificial intelligence data centers. LG Group has built a position in the data center cooling market centered on large air-cooled and water-cooled chillers, and LG Innotek is expected to benefit alongside by supplying power and package components for data centers.
Samsung Electro-Mechanics, in fourth place, changed hands at 1.488 million won, down 1.26%. The stock is giving back part of this year's steep gains, but its core multilayer ceramic capacitor (MLCC) business remains on track. MLCCs are high-value components used in AI data centers, and prices are surging amid a persistent supply shortage. The consensus estimate for Samsung Electro-Mechanics' third-quarter operating profit is 600 billion won, according to financial data provider FnGuide, while KB Securities recently projected 660.1 billion won and iM Securities 650 billion won.
The most heavily sold stocks that morning were Isu Specialty Chemical, L&F and Hyundai Motor, in that order. In the previous session, net buying was largest in Samsung Electronics, NAVER and Samsung SDI. The previous day's top net sales were Samsung Electro-Mechanics, Samsung Electronics preferred shares and Exicon.
