News of the police investigation into G-Dragon and YG's executive producer, Yang Hyun-suk, over possible copyright infringement caused YG Entertainment's stock to fall. This followed a six-day stock rise driven by strong Q2 earnings.

At 9:22 a.m. on the 13th, YG Entertainment's stock was at ₩97,200, decreasing by ₩4,900 (4.80%) from the previous day. The stock opened at ₩102,000 and dropped to an intraday low of ₩97,100, a 4.89% slide.

The recent decline contrasts with YG's prior success. On August 8, YG reported a return to profitability in Q2, with ₩100.4 billion in revenue and ₩8.4 billion in operating profit. Net income was ₩11.2 billion, positive year-on-year. The stock reached a 52-week high at ₩104,900 on August 12.

Police sources state that Seoul’s Mapo Police Station began investigating last November after composer A accused G-Dragon and Yang Hyun-suk of breaching copyright by using his work without permission in an album.

YG Entertainment refuted the accusations. An official told Ilgan Sports that the issue arose from a 2009 solo concert where two songs with the same title were mistakenly listed, not from unauthorized album use.

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