AI Stocks Plummet Amid Investor Concerns

South Korean equities slid sharply on Tuesday, with Samsung Electronics and SK Hynix falling more than 10 % as investors tightened their stance on the semiconductor sector. The decline pushed the KOSPI index to its lowest level in three months, reflecting a broader sell‑off in AI‑related stocks that has intensified over recent days. Market participants cited growing concerns about the heavy borrowing undertaken by AI firms to expand data‑centre capacity, which could weigh on future profitability.

The dip in the two flagship chip makers came amid renewed worries that Chinese competition and a slowdown in global demand for memory chips could erode margins. Analysts noted that the rapid pace of AI adoption has driven up capital expenditures, yet the associated debt burden may limit the ability of firms to invest further. The sell‑off also highlighted the sensitivity of the market to any signs of a broader slowdown in the technology sector, with investors seeking safer assets amid uncertainty.

In the aftermath, the broader market remains volatile, and the KOSPI is likely to stay under pressure until clearer signals emerge regarding the sustainability of AI‑driven growth and the competitive landscape in the semiconductor industry.
