During Asian trading hours on October 29, Japanese and South Korean markets consolidated at high levels as rally momentum slowed following historic surges. The KOSPI rose 1.03% to 6,074.43 points, with SK Hynix breaking 1,537,000 won, while the Nikkei 225 gained 0.79% to 64,460.44 points. Globally, the Federal Reserve kept rates unchanged at 3.75%–4.00%, though two dissenting votes and sticky inflation concerns drove a rebound in 10-year US Treasury yields, suppressing tech stock momentum. Meanwhile, Samsung Electronics held its Q3 earnings call, focusing investor attention on HBM shipment progress and capital expenditures.

AI-generated summary

TradingKey - Rally slows after Japan and South Korea markets surge; KOSPI holds above 6,000 points, Kioxia jumps over 5%, and SK Hynix breaks 1.5 million won.

During Asian trading hours on October 29, after experiencing historic surges over the previous two days, the Japanese and South Korean capital markets opened with high-level consolidation and slowing momentum today. Among them, the KOSPI rose 1.03%, remaining above the 6,000-point mark at 6,074.43 points; Samsung Electronics gained 0.83% to 244,000 won; SK Hynix surged 3.43%, breaching the 1.5 million mark to stand at 1,537,000 won.

The Nikkei 225 Index opened higher and extended gains for the third consecutive day, rising 0.79% to 64,460.44 points; Kioxia surged 5.2%, breaching the 150,000 mark to stand at 15,085 yen; SoftBank rose 1.5% to 4,752 yen.

The Federal Reserve kept its benchmark interest rate unchanged in the 3.75%–4.00% range, but there were two dissenting votes in this statement (advocating a 25-basis-point rate hike), and the meeting minutes showed that officials still harbored concerns about sticky inflation. This directly caused a short-term rebound in the 10-year US Treasury yield, suppressing the momentum of multinational high-frequency capital blindly chasing tech stocks higher at the Asian market open and causing the market rally to slow.

Samsung Electronics held its Q3 earnings conference call today, with the market closely watching its latest statements regarding HBM3e/HBM4 shipment progress and capital expenditures.
