Market Overview

Most Asian equity markets traded within narrow ranges on Friday, with the South Korean KOSPI emerging as the region's weakest performer. The KOSPI slipped roughly 1.3% (reported as a 1.28% decline), driven primarily by losses in heavyweight semiconductor stocks. SK Hynix and Samsung Electronics each fell between 1.5% and 2.5% after having posted strong gains earlier in the week on Nvidia's earnings‑driven AI optimism.

U.S. Rate Outlook Influence

U.S. markets provided a mildly positive backdrop after Nvidia (NASDAQ:NVDA) surged 8.74% on its blowout quarterly results, lifting the Nasdaq. However, Wall Street closed largely flat as investors grew cautious ahead of Federal Reserve Chair Kevin Warsh’s speech at the Jackson Hole Symposium, anticipating further guidance on the trajectory of U.S. interest rates. Wall Street futures remained muted during Asian trading hours, reflecting the market’s wait‑and‑see stance.

Japanese Market Reaction

In Japan, the Nikkei 225 and TOPIX outperformed the broader region, advancing between 0.7% and 0.9%. The gains were underpinned by the release of August consumer‑price index data, which showed core inflation staying close to the Bank of Japan’s 2% annual target, while producer‑side inflation had risen sharply in recent months. The data reinforced expectations that the BOJ may raise rates soon.

Chinese and Other Regional Indices

China’s Shanghai‑Shenzhen CSI 300 slipped 0.1%, the Shanghai Composite edged up 0.1%, and Hong Kong’s Hang Seng added 0.3%. Despite the modest moves, mainland Chinese markets were projected to post more than a 1% rise for the week, supported by positive earnings reports. Australia’s ASX 200 rose 0.4%, Singapore’s Straits Times Index was flat, and futures for India’s Nifty 50 index rose 0.2%.

Investor Sentiment on AI Chip Valuations

Investors remained wary of the elevated valuations of AI‑driven chipmakers. Recent shareholder‑return announcements from SK Hynix and Samsung offered limited price support, leaving the sector sensitive to any further cues on U.S. monetary policy and bond‑market volatility.
