The KOSPI fell 1.18% to 6,831.11 points, while the KOSDAQ rose 1.97% to 817.72 points, reflecting a divergence between large‑cap sell‑off and niche‑sector rallies. The won traded at 1,384.51 per US dollar. Investor sentiment was mixed, with broad weakness in the main index offset by strong buying in battery‑related and gold‑token stocks.
SAMSUNG SDI CO.,LTD. (006400) +8.16%

Analyst consensus — 22 ratings, last 180 days · avg target ₩715,091
Samsung SDI surged 8.16% after foreign investors and institutions simultaneously posted net buying, expanding demand pressure on the shares (NewsPim, Aug 20) [1]. The company also secured 4.5 trillion KRW of funding, which improves its balance sheet and fuels expectations for expanded ESS (energy‑storage system) investments (gukjenews.com, Aug 24) [2]. Financing was further supported by the sale of a 4.5 trillion KRW stake in Samsung Display, earmarked for ESS projects (Daum, Aug 21) [3]. These factors combined to drive today’s rally.
ITCENGLOBAL (124500) +19.97%

ITCENGLOBAL jumped 19.97% as the rebound in gold prices lifted its gold‑linked token business, a direct beneficiary highlighted in several reports (Chosunbiz, Aug 24; MoneyToday, Aug 24; NATE, Aug 24) [7,10,12]. The firm’s recent inclusion as a subsidiary of the Korea Gold Exchange further amplified investor optimism about its token platform (Korea Economy, Aug 24) [11]. No specific earnings or contract news were disclosed, so the price surge is primarily attributed to commodity‑price dynamics and the strategic affiliation.
L&F (066970) +16.56%

Analyst consensus — 19 ratings, last 180 days · avg target ₩199,000
L&F rose 16.56% on the back of eight consecutive days of institutional net buying, which intensified buying pressure (NewsPim, Aug 20) [13]. The broader 2nd‑battery rally, driven by growing Tesla demand and expanding ESS projects, helped the stock outpace peers (NATE, Aug 24; Monday Newspaper, Aug 24; Cookie News, Aug 22) [15,16,17]. The rapid 17% intraday surge also triggered a volatility‑interrupt (VI) mechanism, underscoring the speed of the rally (CBC News, Aug 24) [14].
POSCO FUTURE M (003670) +10.07%

Analyst consensus — 17 ratings, last 180 days · avg target ₩219,000
POSCO Future M gained 10.07% as it confirmed entry into the LFP battery and ESS markets and secured a six‑year, 190,000‑tonne cathode material order, sparking strong supply‑side expectations (Mshale, Aug 22; Mshale, Aug 20; Mshale, Aug 21) [19,21,23]. Nevertheless, concerns over the overall 2nd‑battery material outlook caused a 5%‑plus pullback earlier in the week (Jaegyeong Ilbo, Aug 21) [20]. Anticipation of the upcoming half‑year report added further intraday buying momentum (Jaegyeong Ilbo, Aug 20) [22].
SIMMTECH Co., Ltd. (222800) +9.33%

Analyst consensus — 10 ratings, last 180 days · avg target ₩163,500
SIMMTECH climbed 9.33% despite a volatile week. On Aug 21 the stock fell 13.14% after large institutional net selling, as reported by TopStar News and NATE (TopStar News, Aug 21; NATE, Aug 21) [24,27]. Conversely, on Aug 20 the company announced a 300 billion KRW capital‑raising plan, prompting a 3.79% intraday rise (TopStar News, Aug 20; Seoul Economic, Aug 20) [26,28]. The broader market weakness in the third week of August was noted but not directly linked to the stock’s movement (TopStar News, Aug 22) [25].
