SK eternix (475150) +30.00%

P/E	P/B	EPS	Mkt Cap	ROE	Debt Ratio	52W Range
88.57	9.96	910	₩2.7T	9.60%	419.70%	17,210–80,600

SK eternix surged by the daily limit of 30.00% on July 23, 2026. The rally was driven by rising global oil prices, which spotlighted renewable energy firms [2, 5], alongside the company's participation in offshore wind power projects [5]. Sentiment was further lifted by expectations regarding KKR's business restructuring [3]. Strong market demand supported the stock, marked by a nine-day consecutive buying streak by institutional investors [4] and simultaneous net buying by both foreign and institutional players [6]. The specific "two reasons" mentioned in headline [1] remain unconfirmed from the headlines alone.

NAVER (035420) +11.73%

P/E	P/B	EPS	Mkt Cap	ROE	Debt Ratio	52W Range
17.78	1.19	12,376	₩34.5T	6.49%	45.21%	181,100–304,000

NAVER climbed 11.73% on July 23, 2026, with its intraday price touching 210,000 KRW [7]. The primary driver behind this strong upward movement was heavy institutional and foreign investor demand, as both groups engaged in simultaneous net buying [8]. While the stock also recorded gains earlier in the week on July 21 [9], the specific corporate earnings, business developments, or broader macroeconomic catalysts triggering these intraday surges remain unconfirmed from the provided headlines alone.

DaewonCable (006340) +16.78%

P/E	P/B	EPS	Mkt Cap	ROE	Debt Ratio	52W Range
125.66	9.3	113	₩1.1T	9.86%	120.57%	2,765–20,300

DaewonCable advanced 16.78% on July 23, 2026, continuing a multi-day upward trend [10, 13]. The stock's gains were primarily fueled by a sector-wide rally in cable and wire themes [12, 14]. Both the common stock and preferred shares rose in tandem, with the preferred shares even triggering a volatility interruption (VI) mechanism during the week [11]. While analysts suggest buying on dips [15], the specific industry-wide catalysts driving the broader cable sector's current strength remain unconfirmed from the provided headlines alone.
