Samsung Electronics surged 5.43% to lead the KOSPI. The rally was driven by expectations that the company will boost its shareholder‑return program to more than ten‑fold, potentially reaching 200 trillion won, which analysts see as a catalyst for price re‑valuation and a return of foreign investors. The policy contrast with rival SK Hynix added a differential edge. KB Securities labeled the stock a “confidence‑buy zone” and kept its target price at 600,000 won, reinforcing bullish sentiment.

KUMHOE&C rocketed 29.98% after hitting the daily upper‑limit. Market participants priced in optimism surrounding the planned Honam semiconductor industrial complex, which lifted the broader Kumho Group stocks and pushed the construction firm to the ceiling [7]. Anticipation of its Q2 earnings further stoked buying pressure from the opening session [10]. Two volatility‑interrupt (VI) triggers were activated during the surge, accelerating the move to the limit price [9].

Cosmecca Korea climbed 13.89% following an earnings surprise that beat expectations, prompting upbeat analyst coverage [13][16][17]. Kyobo Securities upgraded its target price, citing diversified customers, product mix and robust order flow as drivers of continued sales growth [14]. NH Securities also raised its target to 140,000 won, reinforcing the positive outlook [18]. The combined upgrades and strong quarterly results fueled the sharp rally.

BH surged 11.67% on expectations of a record‑high earnings outlook, which lifted investor sentiment [20]. The stock also benefited from speculation that it will participate in Samsung’s robot and humanoid projects, and from a broader AI‑driven power shortage that is boosting demand for solid‑oxide fuel cells (SOFC) like those BH develops [21][22]. These themes combined to drive the notable intraday gain.

Samsung SDS rose 4.49% after a volatile session. Early in the day, foreign and institutional investors sold, pushing the price down by over 4% [24]. However, a rebound was sparked by a favourable IT‑services environment, which helped recover sentiment and lift the stock by more than 5% intraday [26][27]. The net effect was a modest gain despite the earlier sell‑off.
