[Key Issue Briefing]
■ Target price gap: As shares of Samsung Electronics (005930.KS) and SK hynix (000660.KS) have slid sharply, the gap between brokerages' average target prices and actual share prices has widened beyond 100%. Expectations for profit growth in semiconductors remain intact, but with U.S. long-term Treasury yields rising above 5%, analysts say the divergence between industry outlooks and share price moves is growing.
■ Diverging flows: Foreign investors pulled large sums out of large-cap chip stocks while selectively buying shares in the AI infrastructure supply chain. Retail investors, by contrast, concentrated purchases on leveraged index and semiconductor exchange-traded funds during the selloff, betting on a rebound.
■ AI boom and prices: Bank of Korea Governor Shin Hyun-song said AI investment exceeding $1 trillion over the next three to four years will support global trade and the Korean economy. At the same time, strong chip exports and rising oil prices stemming from the war in the Middle East are pushing prices higher in tandem.
[News of Interest to Financial Product Investors]
1. Samsung and SK hynix Tumble, but Analysts' Targets Remain More Than Double
- Key summary: The average target prices brokerages have set for Samsung Electronics and SK hynix are more than double their actual share prices. Over the past three months, the average target price for Samsung Electronics was 495,227 won, 113.5% above its closing price of 232,000 won on the 14th. For SK hynix, the average target was 3,257,727 won, 129.6% above its closing price of 1,419,000 won. Earnings growth — including Samsung Electronics' preliminary third-quarter operating profit of 107.4 trillion won — underpins the maintained targets. "Share prices will ultimately converge toward target prices," said Lee Jin-woo, head of the research center at Meritz Securities (008560.KS). Meanwhile, with U.S. long-term Treasury yields climbing above 5%, concerns are also mounting that prolonged high interest rates could threaten the AI investment cycle.
2. With Delistings on Hold, Stocks Facing Removal Surge to Daily Limits
- Key summary: After a court ruling prompted the Korea Exchange to suspend follow-up delisting procedures for stocks failing to meet market capitalization requirements, those shares jumped. Of 49 stocks under administrative watch for falling short of market cap thresholds, 35, or 71.4%, rose from their closing prices on the 7th of this month, a period in which the KOSPI fell 11.69% and the KOSDAQ dropped 8.30%. Bioinfra surged 185.0%, while Hyungji I&C (011080.KS), up 122.1%, and YeSUN Tech (250930.KQ), up 98.5%, roughly doubled. Still, the procedural suspension does not mean the grounds for delisting have been resolved, and the stocks remain designated as administrative issues, warranting investor caution.
3. Foreign Investors Dump 18 Trillion Won in Top Two Chipmakers, Buy AI Equipment and Parts Stocks
- Key summary: Foreign investors sold a net 23.0819 trillion won on the main board from the 23rd of last month, with SK hynix and Samsung Electronics accounting for 18.3256 trillion won, or 79%, of that total. By contrast, they bought 128.6 billion won worth of Isu Petasys (007660.KS), a maker of high-layer-count multilayer printed circuit boards for AI servers, and 74.7 billion won worth of Samwha Capacitor, a maker of multilayer ceramic capacitors. DB HiTek (000990.KS) and Hanmi Semiconductor (042700.KS) also ranked among the top net purchases. Foreign investors also bought 528.6 billion won worth of Woori Financial Group (316140.KS), a high-dividend defensive play, making it their largest net purchase overall. Fund flows thus diverged sharply by individual stock.

4. On Black Tuesday, Retail Investors Bet on KOSPI and Semiconductor Leverage
- Key summary: On the 13th, when the KOSPI plunged more than 6%, retail investors concentrated purchases on leveraged index and semiconductor ETFs. They bought 361 billion won worth of KODEX Leverage, which tracks twice the daily return of the KOSPI 200, along with 100.4 billion won of KODEX KOSDAQ 150 Leverage and 59.3 billion won of KODEX Semiconductor Leverage. Inverse products, by contrast, saw a wave of profit-taking. According to Kiwoom Securities (039490.KS), forward price-to-earnings ratios for the KOSPI and for semiconductors stood at 4.6 times and 3.2 times, respectively, near record lows.
- Key summary: Korean and U.S. stock markets swung sharply on China-based Changxin Memory Technologies' announcement that it would release its next-generation 4F² DRAM technology within the year. Kwon Suk-joon, a professor at Sungkyunkwan University, said the announcement should be read as a product preview, since it contained no reference to mass production or samples. Meaningful mass production is expected no earlier than late 2027 and realistically in the first half of 2028. Analysts also said CXMT's 15-nanometer 4F² cell is similar in area to the 12.2-nanometer 6F² cells used by Korean manufacturers, making it difficult to view as a leap ahead in density. Samsung Electronics has already unveiled a prototype with a 4F² structure. Still, assessments followed that the buffer created by U.S. export controls on extreme ultraviolet lithography equipment is narrowing.
- Key summary: Bank of Korea Governor Shin Hyun-song said on the 14th, in a CNN interview held in Bangkok, Thailand, that the AI investment boom will support global trade and the Korean economy, citing expectations of more than $1 trillion in investment over the next three to four years. He added, however, that Korea sits at the intersection of large-scale AI investment and the war in the Middle East, and that the two trends combine to fuel inflation in terms of prices. The central bank raised its base rate by 0.25 percentage point in both July and August, and its next monetary policy board meeting is set for the 22nd.
