“If SK Hynix just recovers to ₩2.3 million (approximately $1,549), I’ll sell the entire position without a second thought.”
That’s what high-net-worth investor A, who has roughly ₩3 billion (approximately $2.0 million) parked in Samsung Electronics (005930.KS) and SK Hynix (000660.KS), recently told his dedicated private banker. In the past, he would have added to his holdings on every dip, but the relentless whipsaw of recent sessions has left him exhausted and sitting entirely in cash.
As South Korea’s stock market rides a so-called roller-coaster, wealthy investors are likewise showing signs of fatigue and confusion. According to the securities industry on July 17, major brokerage PB centers are fielding a barrage of sell inquiries from the super-rich, but most are merely testing exit timing — few have actually pulled the trigger. Front-line private bankers unanimously describe their clients as having entered “wait-and-see mode.”
A survey of roughly a dozen PB centers at major South Korean securities firms reveals that both new inflows and additional buying have frozen solid. Choi Sun-yi, team leader at Mirae Asset Securities’ Pyeongchon WM Center, said, “Even when we recommend adding to positions, the mood is resistant,” adding that “the entire center was busy talking investors who wanted to sell out of it.” He noted that “shrinking financial capacity among the wealthy is also a factor.” With stock allocations already significantly elevated, even advice that “this is the bottom” is met with extreme caution.
Only a tiny minority of investors bought the dip on domestic stocks amid unprecedented volatility — limited to a handful of wealthy individuals who had cashed out and stockpiled dry powder since June. Investor B, who sold roughly ₩1 billion (approximately $674,000) worth of Samsung Electronics shares when the stock was at ₩350,000 (approximately $236), redeployed the entire sum into South Korean blue chips on July 14, including buying back several hundred million won worth of Samsung Electronics. Lee Beom, team leader at Korea Investment & Securities’ Jamsil PB Center, explained, “He succeeded in re-entering because he had taken profits back in June with July volatility in mind.”
By contrast, latecomer super-rich investors who chased the rally belatedly are now exhibiting panic selling. While high-net-worth individuals typically refrain from hasty selling even in a crash, those who recently liquidated real estate and deposits to jump into the Kospi rally are an exception. Selling sentiment has taken hold among this cohort. Kim Gyu-beom, director at NH Investment & Securities’ Premier Blue Gangbuk 3 Center, recounted: “One wealthy client who liquidated real estate in April and bought tens of billions of won in large-cap Kospi stocks had already offloaded more than half by early July. It’s an environment that makes them vulnerable to panic selling.”
This contraction in investor sentiment was laid bare on July 16, when the Kospi once again surrendered the 7,000 level in a sharp sell-off. The benchmark closed down 463.81 points, or 6.37%, at 6,820.60, while the Kosdaq also gave up the 800 mark. The Kospi opened more than 4% lower, and by 9:10 a.m., a sell-side sidecar was triggered as Kospi 200 futures tumbled. At 10:20 a.m., a sell-side sidecar was also activated on the Kosdaq, with market stabilization mechanisms firing simultaneously across both exchanges.
According to the Korea Exchange, foreign investors net sold ₩1.41 trillion (approximately $947.2 million) and institutions offloaded ₩2.37 trillion (approximately $1.6 billion) on the Kospi that day, while retail investors net bought ₩3.67 trillion (approximately $2.5 billion) in a bid to prop up the market — but it wasn’t enough to stem the decline. Sidecars were triggered on all four trading days of the week, with market volatility surging to extreme levels. So far this year, Kospi sidecars have been activated 36 times, Kosdaq sidecars 22 times, and circuit breakers a cumulative nine times.
The declines were particularly severe among market leaders Samsung Electronics and SK Hynix, which together account for half of total market capitalization. Samsung Electronics closed down ₩24,500 (approximately $16.50), or 8.77%, at ₩255,000 (approximately $172), while SK Hynix tumbled ₩240,000 (approximately $162), or 11.53%, to ₩1,842,000 (approximately $1,241). SK Square fell 12.30% and Samsung Electro-Mechanics dropped 9.62%, with top-cap stocks weakening across the board.
Lee Kyung-min, an analyst at Daishin Securities, said, “South Korea’s stock market plunged, led by Samsung Electronics and SK Hynix, as semiconductor industry concerns resurfaced,” adding that “sharp drops in Micron (-8.0%), SanDisk (-8.1%), and Western Digital (-8.8%) also weighed negatively on domestic semiconductor sentiment.” The diagnosis: worries over expanding memory supply, a potential slowdown in data center investment, and fears that memory prices have peaked have broadly undermined sentiment across the chip sector.
Kang Jin-hyuk, an analyst at Shinhan Investment & Securities, also noted, “The Kospi triggered a sell-side sidecar amid profit-taking following the previous day’s surge and persistent semiconductor doubts,” adding that “semiconductor skepticism continues, with memory stocks plunging in the U.S. as well on chip-related noise.” Meanwhile, the Bank of Korea’s rate hike (from 2.50% to 2.75%) was in line with market expectations and is assessed to have had a limited impact on equities.
As buying momentum in large-cap Korean stocks has slowed, interest in volatility hedges has risen. Attention that had been concentrated on Samsung Electronics and SK Hynix is now dispersing toward defensive stocks, fixed-rate products, and other stable investment options. Equity-linked securities (ELS), long overlooked, are also drawing attention, since their expected returns rise as volatility increases. U.S. semiconductor stocks and South Korean consumer staples are also being mentioned.
Analysts on the Street now assess that the Kospi has entered a mid-term correction phase. Kim Seok-hwan, an analyst at Mirae Asset Securities, diagnosed that “technical indicators suggest mid-term correction pressure is gradually intensifying,” and that “even if the current decline halts, the 50-day moving average (7,983 points) and the prior high (9,114 points) are likely to act as resistance.” He stressed that “reclaiming the 9,000 level will require stronger upward momentum — something that exceeds market expectations, such as an SK Hynix second-quarter earnings surprise, a significant upward revision in AI hyperscaler CAPEX, or an easing of supply-demand instability surrounding single-stock leveraged ETFs.”
The industry expects wealthy investors’ wait-and-see stance to persist for some time. The prevailing view is that investor sentiment will only revive once volatility subsides to a level that market participants can actually feel.
