Samsung Electronics reported a remarkable 19-fold increase in second-quarter operating profit, reaching 89.4 trillion won, surpassing market expectations of 87.3 trillion won. Despite this impressive performance, the company's stock price fell sharply, reflecting investor concerns over the sustainability of the AI-driven chip boom. The decline in Samsung's stock contributed to a broader market impact, dragging the KOSPI index down by 6%. This highlights ongoing apprehensions about the long-term viability of current growth trends in the semiconductor sector, despite the company's record-breaking profits.
