South Korean markets were under pressure at midday, with the KOSPI down 3.77% to 6,577.99 and the KOSDAQ slipping 1.76% to 806.79. The won weakened to 1,368.52 per dollar, reflecting a risk‑off mood, yet a handful of small‑cap stocks posted double‑digit gains.
KUMHOE&C (002990) +5.76%
Construction firm Kumho E&C surged 5.76% after a series of recent intraday moves that hinted at volatility. On Aug 31 the stock rose 2.70% to 17,480 KRW, while on Sep 1 it fell 2.79% to around 16,000 KRW, showing a swing in sentiment. A report on Sep 2 described a “sharp rally” but did not identify a specific catalyst, leaving the driver of today’s gain unclear. The mixed recent price action likely contributed to the current bounce.
SamwhaCapacitor (001820) +2.93%
Samwha Capacitor advanced 2.93% despite the lack of any confirmed news catalyst in the recent press. With the broader market trending lower, the move may reflect sector‑wide buying or technical factors, but no specific driver can be verified from available sources.
DI (003160) +14.82%
DI rallied sharply, up 14.82%, as investors chased stocks tied to inter‑Korean economic cooperation, which have been broadly rising [4]. Buying pressure intensified even without a concrete news item, pushing the share into the mid‑teens gain range [5]. Analysts also highlighted expectations that the company will resume HBM (high‑bandwidth memory) investments and benefit from an improving earnings structure, further fueling optimism [6][7].
YC Corporation (232140) +10.30%
YC Corporation posted a 10.30% jump, standing out as semiconductor peers Samsung and Hynix fell over 3%. Market commentary noted that YC’s “reverse‑run” relative strength against the sector slump attracted buying interest, as investors perceived it as a defensive play within a weakening chip market [8].
TAEWOONG CO., LTD. (044490) +10.04%
TAEWOONG surged 10.04% on expectations that its TerraPower SMR (small modular reactor) contract could be awarded in September, prompting a wave of buying despite overall index declines [9]. An analyst report released on Aug 30 may have reinforced the positive outlook, though the report’s specifics are not disclosed in the headline [10].
