Samsung Electronics surged 3.87% as media reports suggested an imminent 100‑trillion‑won shareholder‑return programme, including dividends and buy‑backs, sparking a 5‑10% rally in the stock [1][4]. The market also linked the move to SK Hynix’s 40‑trillion‑won buy‑back, which raised expectations that Samsung would follow with a similarly large return plan, further boosting investor optimism [3].

Samsung Life Insurance jumped 10.61% after analysts at Kiwoom Securities upgraded the target price to 380,000 won despite a Q2 profit decline, citing strong growth prospects for the insurer [7]. The price lift was reflected in multiple market updates reporting a rise to 31,500 won by the close of trade [12] and earlier intraday gains [9]. The upward move occurred amid broader market weakness driven by higher U.S. rates and a slump in semiconductor stocks, which did not dampen the insurer’s rally.

SK Securities rose 5.16% after it was confirmed as the broker for SK Hynix’s 40‑trillion‑won share‑repurchase, a deal that could generate at least 4 billion won in fees and markedly improve the broker’s revenue outlook [13][15]. The news triggered a buying frenzy that pushed the stock to the daily upper limit for two consecutive sessions, a pattern typical of “featured stocks” [16][17]. A volatility‑indicator (VI) trigger later in the session added an automatic buy signal, further supporting the rally [18].

Samsung C&T advanced 5.75% as foreign investors logged an 11‑day streak of net buying, strengthening demand for the shares [19]. The company also announced a special dividend using its stake in Samsung C&T, which heightened investor interest in the parent’s equity and bolstered market expectations [20]. Additionally, a contract amendment filing released on August 20 signaled improved supply‑demand dynamics, prompting a mid‑session price lift [22].

SK Telecom climbed 5.80% despite earlier concerns over half‑year earnings pressure that had weighed on the stock [27]. Positive short‑term sentiment resurfaced after headlines on August 18 reported a price rise and a 5,600‑won gain at the close of trade on August 21, indicating renewed buying momentum [26][30]. The combination of transient buying pressure and the fading impact of earlier earnings worries helped the stock reverse its prior decline.
