The KOSPI is displayed on a monitor in the dealing room at Hana Bank’s headquarters in Jung-gu, Seoul, on the 6th. That day, the KOSPI opened at 8,186.82, up 98.48 points (1.22%) from the previous session, while the KOSDAQ opened at 866.40, down 2.01 points (0.23%). Yonhap News<\/p>\n
The trading value of SK Group’s listed affiliates has surpassed half of the total trading value among corporate conglomerates. The concentration reflects an explosive surge in trading of SK hynix (000660.KS) amid the artificial intelligence (AI) chip rally. Over the past month, single-stock leverage products tracking SK hynix have also swept the top ranks for fund inflows in the exchange-traded fund (ETF) market. With a U.S. American Depositary Receipt (ADR) listing scheduled this week, concerns are emerging that the flow of funds into SK hynix could intensify further.<\/p>\n
According to the Korea Exchange on Thursday, the 19 listed affiliates of SK Group recorded a combined trading value of 20.7593 trillion won on Wednesday, the previous trading session, accounting for 51.67% of the total trading value among corporate conglomerates. The amount traded in SK Group alone exceeded that of all other conglomerates combined (48.33%).<\/p>\n

This represents an unusual concentration of trading even compared with SK Group’s size. SK Group accounts for 35.39% of the total market capitalization among conglomerates, lower than Samsung Group (39.94%). Yet SK Group’s share of trading value stood at 51.67%, far ahead of Samsung Group (32.29%). While Samsung’s market capitalization was larger, actual trading funds were more heavily concentrated in SK.<\/p>\n
The concentration of trading value into SK Group was effectively led by SK hynix. As brokerages issued a series of reports raising SK hynix’s target price above 4 million won based on upward earnings estimates, its trading volume reached 7,984,914 shares on Wednesday, accounting for roughly 90% of SK Group’s total trading value. Including SK Square, SK hynix’s largest shareholder, the two stocks are estimated to account for 98% of SK Group’s total trading value.<\/p>\n
Beyond the cash market, fund inflows into single-stock leverage ETFs are also cited as a factor amplifying buying pressure for SK hynix. According to Koscom’s ETF CHECK, the top ETF for net fund inflows over the past month was the “KODEX SK hynix Single-Stock Leverage,” which drew 3.1478 trillion won. The fourth-ranked “TIGER SK hynix Single-Stock Leverage” also saw 1.3774 trillion won in inflows. The two products alone drew 4.5252 trillion won, about 2.5 times the inflow (1.8241 trillion won) of the second-ranked “KODEX Samsung Electronics (005930.KS) Single-Stock Leverage” over the same period. Because single-stock leverage ETFs use SK hynix shares and derivatives to adjust exposure in the process of tracking twice the underlying asset’s daily return, large-scale fund inflows into the products can expand buying demand for the underlying stock and reinforce trading concentration.<\/p>\n
In the market, SK hynix’s ADR listing in the United States, scheduled for Wednesday, is cited as an additional variable that could reinforce such concentration. As access improves for foreign investors and a new trading price forms in the global market, expectations for a re-rating of SK hynix’s value could grow, further heightening investor interest.<\/p>\n
With a significant portion of Korea’s stock market trading value already concentrated in a small number of leading stocks such as SK hynix, and funds pouring into single-stock leverage products, some point out that market volatility could increase if dependence on specific stocks rises further. “Semiconductor-centered earnings upgrades ultimately signal concentration into leading stocks,” said Kim Jun-young, a researcher at iM Securities. “The more factors that shake the stock market, the more investors need to rely on leading stocks, but an environment where the volatility of leading stocks inevitably remains large raises the difficulty of investing.”<\/p>\n","protected":false},"excerpt":{"rendered":"The KOSPI is displayed on a monitor in the dealing room at Hana Bank’s headquarters in Jung-gu, Seoul,…\n","protected":false},"author":2,"featured_media":76250,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[457],"tags":[2692,16082,337,864,223,12720,240,275,41262],"class_list":["post-76249","post","type-post","status-publish","format-standard","has-post-thumbnail","category-korea-exchange","tag-adr-listing","tag-ai-chip-rally","tag-korea-exchange","tag-krx","tag-samsung-group","tag-single-stock-leverage-etf","tag-sk-group","tag-sk-hynix","tag-trading-value-concentration"],"_links":{"self":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/posts\/76249","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/comments?post=76249"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/posts\/76249\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/media\/76250"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/media?parent=76249"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/categories?post=76249"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/tags?post=76249"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
