Chip-led surge powers sharp Kospi rebound

South Korea’s benchmark Kospi has staged a swift rebound since its July 30 low, with recent trading sessions showing particularly strong moves. One session saw the index gain 3.6%, while at another point it jumped more than 4% in early trade. These advances have lifted the Kospi roughly 22% to 23% above its late‑July trough over a short period.

Market coverage characterizes this rise as a rapid recovery from last month’s sharp sell‑off. The scale and speed of the move have drawn attention across Asia-Pacific markets, as the Kospi outpaced many regional peers during this stretch.

The rally has been heavily concentrated in large-cap memory makers. Samsung Electronics and SK Hynix (SKHY) led the latest gains, with Samsung rising roughly mid-single digits and SK Hynix (SKHY) climbing by a high-single-digit percentage during recent sessions.

Because these stocks carry significant weight in the index, their moves have had an outsized effect on headline Kospi performance. Both outlets covering the market emphasized that this concentration means swings in just a few names can materially change the overall index level.

Renewed optimism about demand for AI-related memory chips has been a key driver behind the strength in Samsung and SK Hynix. Strong earnings from major U.S. technology firms have reinforced expectations for continued investment in AI infrastructure, supporting assumptions about future chip demand.

At the macro level, U.S. July consumer price index data coming in line with expectations has eased concerns over a potential interest-rate move in September. This softer-than-feared inflation backdrop has improved risk sentiment across Asia-Pacific markets, including South Korea.

Some overseas funds have begun to flow back into Korean equities alongside the index’s recovery. However, foreign investors remain net sellers on the year, indicating that longer-term conviction among global investors is still cautious.

Analysts cited in the coverage warn that the durability of the rebound depends on how long AI-driven memory demand and supportive U.S. interest-rate conditions persist. Given the Kospi’s heavy weighting toward a few large memory-chip names, any reversal in these factors could have a pronounced effect on the broader market.
