KOSPI Surges Past 7,000 Level as Tech and Renewable Energy Shares Rally

The Korean market experienced a powerful rally at midday, with the benchmark KOSPI surging 5.01% to 7,086.33 and the tech-heavy KOSDAQ rising 2.85% to 774.79. The USD/KRW exchange rate hovered at 1,478.63 amid broad-based buying interest that bolstered major sectors.

SK eternix (475150) +19.50%

P/E	P/B	EPS	Mkt Cap	ROE	Debt Ratio	52W Range
73.52	8.26	910	₩2.3T	9.60%	419.70%	17,210–69,800

SK eternix jumped 19.50% at midday, driven by a surge in international oil prices that significantly boosted investor sentiment for the renewable energy sector [1][5][6]. Market optimism was further fueled by expectations surrounding KKR's business reorganization and a newly proposed target price of up to KRW 66,000 [2]. Strong concurrent net buying from both foreign and institutional investors also provided substantial upward momentum [3]. On July 22, the stock had previously touched KRW 68,200 during intraday trading [4].

LGELECTRONICS (066570) +9.30%

P/E	P/B	EPS	Mkt Cap	ROE	Debt Ratio	52W Range
35.61	1.43	5,321	₩30.9T	4.11%	133.33%	72,000–438,000

LG Electronics climbed 9.30%, fueled by growing investor optimism regarding its potential cooperation with Nvidia and future artificial intelligence (AI) achievements [7][8]. While some reports pointed to a 'hidden growth engine' driving the stock, specific details remain unconfirmed [9]. This rebound follows recent downward pressure on July 20 and 21, when the stock suffered from expanding sell-offs by foreign and institutional investors, which had temporarily weakened market sentiment [10][11][12].

DaewonCable (006340) +12.16%

P/E	P/B	EPS	Mkt Cap	ROE	Debt Ratio	52W Range
116.55	8.62	113	₩1.0T	9.86%	120.57%	2,765–20,300

Daewon Cable rose 12.16% as cable manufacturers continue to benefit from surging power demand driven by artificial intelligence (AI) infrastructure expansion [18]. The stock's gains were supported by a broader upward trend across the entire cable sector [14]. Analysts have recently recommended the stock as a promising pick, advising investors to accumulate shares during price dips [16][17]. This follows volatile trading earlier in the week, including a 7.52% drop on July 20 [15] and a 7.77% intraday rise on July 21 [13].
