The stock decline follows news of investigations involving singer G-Dragon and executive Yang Hyun-suk over copyright issues. This downturn breaks a six-day rise after strong Q2 results.

At 9:22 a.m. on the 13th, shares traded at ₩97,200, falling ₩4,900 (4.80%) from the previous close. Shares opened at ₩102,000 and dropped to ₩97,100, a 4.89% decrease.

This fall contrasts with YG’s recent gains. On August 8, they reported a return to Q2 profits, with ₩100.4 billion in revenue and ₩8.4 billion in operating profit, achieving ₩11.2 billion net income. On August 12, shares reached a 52-week high of ₩104,900.

Seoul’s Mapo Police Station began investigating after composer A's November complaint, accusing G-Dragon and Yang Hyun-suk of unauthorized reproduction and distribution of his work.

YG denies the claims. An official stated to Ilgan Sports that the issue arose from a 2009 concert error, with two identical song titles mistakenly included in a setlist, not unauthorized reproduction.

Police have interviewed involved parties and conducted two raids on YG Entertainment's headquarters for the investigation.
