KOSPI Nears 7,000 as Chip Rally Lifts Nikkei Above 66,000

Key Takeaways

• South Korea’s KOSPI climbed approximately 3.5% in early trading on September 7, while Japan’s Nikkei 225 advanced more than 2%.
• SK Hynix, Kioxia and SoftBank Group gained more than 5%, extending the strength seen in US semiconductor shares on Friday.
• Strong US employment data reinforced interest-rate concerns, leaving the rally exposed to changes in bond yields and monetary policy expectations.

Asian Stocks Rally Despite Wall Street’s Broader Decline

source: tradingview

Japanese and South Korean equities advanced sharply on Monday, September 7, as semiconductor strength carried over from the previous US trading session. The gains highlighted continued demand for technology shares even as the prospect of tighter US monetary policy weighed on broader investor sentiment.

South Korea’s KOSPI reached approximately 6,921.17, up 3.5% in an early-session snapshot and within reach of the psychologically significant 7,000 level. Japan’s Nikkei 225 rose 2.07% to 66,366.55, moving above 66,000 as technology-related shares rallied. These figures represent intraday readings rather than closing prices.

The advance followed a divided session on Wall Street. Major US benchmarks fell on Friday, but semiconductor shares outperformed, providing a more supportive signal for Asian companies exposed to the global computing and electronics industries.

That divergence suggests sector-specific demand remained influential, even while the broader interest-rate environment became less favourable for equities.

Samsung and SK Hynix Lead South Korea’s Advance

Samsung Electronics gained 4.11% to KRW 266,000, while SK Hynix rose 5.46% to KRW 1,737,000 in the supplied early-session snapshot. Their simultaneous advance placed major technology companies at the centre of South Korea’s rebound.

Separate morning readings showed that buying extended beyond those two stocks. SK Square and Samsung Electro-Mechanics advanced, while semiconductor equipment companies also participated. Hyundai Motor and KB Financial traded higher, indicating that the recovery included parts of the market outside technology.

Investor flows provided additional support. By 9:10 a.m. Korea Standard Time, foreign investors had purchased a net KRW 441.6 billion of shares, while institutional investors bought KRW 326.8 billion. Their combined net purchases reached KRW 768.4 billion, against net selling of KRW 812.2 billion by retail investors.

The participation of both foreign and institutional buyers strengthens the evidence of renewed buying interest. However, these figures cover only the opening portion of the session and do not establish whether that demand persisted through the close.

Kioxia and SoftBank Extend Japan’s Technology Gains

In Japan, Kioxia climbed 7.93% to JPY 58,780, while SoftBank Group advanced 6.82% to JPY 5,971. Both outperformed the Nikkei’s percentage gain in the early-session snapshot.

The companies offer different forms of exposure to the technology investment cycle. Kioxia’s business centres on flash memory and solid-state drives, connecting its prospects to demand for storage across computing applications.

SoftBank Group’s connection includes Arm and its expanding role in computing infrastructure. In the group’s 2026 annual report, Arm described cloud AI as its fastest-growing business area and outlined opportunities in data-centre processors and related computing technology.

Those business links help explain why both companies are relevant to the broader AI investment theme. They do not, by themselves, establish the precise cause of Monday’s share-price moves.

US Semiconductor Strength Provides the Immediate Backdrop

US semiconductor shares had already separated from the wider market on Friday, September 4. The Philadelphia Semiconductor Index gained approximately 3.4%, while the Dow Jones Industrial Average, S&P 500 and Nasdaq Composite closed lower.

Memory and storage companies featured prominently among the winners. Sandisk climbed roughly 12%, while Micron Technology, Seagate and Western Digital gained around 6%. The strength across those businesses provided a relevant comparison for Asian memory and storage suppliers entering Monday’s session.

The pattern is consistent with investors continuing to favour parts of the AI hardware supply chain despite broader market pressure.

However, stronger share prices should not be treated as evidence of new orders or an improvement in earnings guidance. Sustaining the recovery will ultimately require corporate results and customer spending to support the expectations reflected in valuations.

Strong Payrolls Keep Interest-Rate Risks in Focus

The US economy added 162,000 jobs in August, while the unemployment rate remained at 4.1%. The employment report was released on September 4.

The stronger-than-expected hiring figures complicated the outlook for US monetary policy. Treasury yields rose as investors reassessed the possibility of another Federal Reserve interest-rate increase. The S&P 500 fell 0.4%, the Dow declined 0.5% and the Nasdaq lost 0.3%.

For Asian technology shares, the implications run in both directions. A resilient US economy may support demand for electronics and investment in computing infrastructure. Higher interest rates, however, can increase financing costs and reduce the present value investors assign to future earnings.

Monday’s gains therefore suggest that enthusiasm for semiconductor exposure outweighed those concerns during early trading. They do not show that monetary policy risks have disappeared.

Can the KOSPI Sustain a Move Toward 7,000?

From 6,921.17, the KOSPI would need to rise approximately another 1.1% to reach 7,000. That makes the round-number level an immediate reference point, although proximity alone does not establish either a breakout or technical resistance.

The next test is whether buying remains broad and whether foreign and institutional demand continues beyond the opening session. A sustained advance across more industries would provide stronger evidence of improving market sentiment than gains concentrated in a few large technology stocks.

For Japan, holding above 66,000 through the close would give the Nikkei’s intraday move greater significance. Across both markets, the durability of the recovery will depend on whether expectations for technology earnings can withstand renewed pressure from US yields and changing interest-rate expectations.
