South Korea's benchmark stock index, KOSPI, rose 3.6% on Thursday, rebounding approximately 22% from its July 30 low, officially entering a technical bull market. This rally was primarily driven by chip stocks such as Samsung Electronics and SK Hynix, both of which saw single-day gains of close to or exceeding 5%. Previously, KOSPI had plummeted 22% in July alone, marking its worst monthly performance since the global financial crisis. Behind this rebound are several factors: sustained high AI capital expenditures by global tech giants, easing inflation data in the US alleviating rate hike concerns, tightened regulatory rules for single-stock leveraged ETFs, and market expectations that Samsung and SK Hynix are about to announce large-scale shareholder return plans.
