The stocks most heavily net sold by high-return investors trading through Mirae Asset Securities (006800) on the morning of the 28th were SK hynix (000660), Samsung Electronics (005930), Samsung Electronics preferred shares (005935) and Daeduck Electronics (353200), in that order.
According to Mirae Asset Securities, the stock most heavily sold by the “stock masters” — the top 1% of the brokerage’s stock trading customers by investment return over the past month — through 11 a.m. was SK hynix.
As of 11 a.m., SK hynix was trading at 1,419,000 won, down 8.45% from the previous session. The stock has fallen sharply for a second consecutive session, as concerns grew over expanded production capacity and intensifying competition in China’s memory industry following the Shanghai listing of Chinese chipmaker ChangXin Memory Technologies (CXMT), compounded by an overnight plunge in U.S. chip stocks.
SK hynix released its preliminary second-quarter earnings before the market opened that day. Revenue came in at 79.3187 trillion won and operating profit at 60.5426 trillion won, up 256.8% and 557.2% respectively from a year earlier. This brought SK hynix’s first-half revenue to 131.895 trillion won and operating profit to 98.1529 trillion won. However, second-quarter operating profit slightly missed the market forecast of 64 trillion won.
Analysts have been lowering their target prices as SK hynix’s share correction continues. Kim Young-gun, an analyst at Mirae Asset Securities, cut his target price for SK hynix to 2.8 million won from the previous 4.2 million won in a report that day. “SK hynix’s recent share correction is excessive relative to its fundamentals,” Kim said, adding, “but given a valuation framework tied to global peers, a target price adjustment reflecting the industry-wide decline is unavoidable.”
The second most net sold stock was Samsung Electronics. At the same time, Samsung Electronics was trading at 212,500 won, down 3.41% from the previous session. Following the previous day, sell-offs continued across artificial intelligence (AI) beneficiary sectors including semiconductors, and Samsung Electronics could not avoid the downturn.
Analysts, however, remain positive on Samsung Electronics’ business outlook. Son In-jun, an analyst at Eugene Investment & Securities, noted, “Memory price negotiations for the third quarter of this year are still proceeding smoothly,” and pointed out, “amid continued supply shortages of general-purpose DRAM and NAND, customers are prioritizing securing volume over price.” He added, “The supply shortage next year is expected to deepen further than this year, and this is likely to lead to additional upward revisions in 2027 earnings estimates.”
The third most net sold stock was Samsung Electronics preferred shares. At the same time, Samsung Electronics preferred shares were trading at 154,000 won, down 2.65% from the previous session.
The top net buys that day were LS Electric, Tes (095610), OCI Holdings (010060) and HYBE (352820). On the previous session, the top net buys were Samsung Electronics, SK Telecom (017670), Samsung Electro-Mechanics (009150) and SK, in that order, while the top net sells included SK hynix, Dalba Global (483650), Doosan Tesna (131970) and Samsung Life Insurance (032830).
