Nikkei Hits Record Highs with Sharpest Weekly Gain Driven by AI Rally
Japan's Nikkei 225 index has delivered a powerhouse performance, marking its strongest weekly surge in nearly two years fueled by intense optimism in the artificial intelligence sector. Despite mid-day volatility triggered by geopolitical tensions, the index managed to sustain its momentum, hitting consecutive record highs during a historic week of trading.
AI and Semiconductor Surge Drive Nikkei Performance
The Nikkei index recorded a massive 7.9% rise for the week, marking its sharpest weekly gain since August 2024. This rally was characterized by seven consecutive sessions of gains, signaling deep-seated investor confidence in Japan's technology ecosystem. On Friday, while the index saw some intraday volatility, it closed 0.28% higher at 71,250.06, after having spiked to a record high of 71,952.99 earlier in the session.
The momentum was largely propelled by the semiconductor and AI-related sectors. Industry leaders such as Advantest rose by 4.75%, while memory maker Kioxia saw a significant jump of 12%. This surge highlights the growing appetite among global investors for Japanese firms that are integral to the global AI supply chain.
Fujikura Leads the Charge with Massive Profit Forecast Upgrade
A standout performer during the session was Fujikura, the fibre-optic cable maker, which surged 15.69% to hit its daily limit high of 5,161 yen. This massive rally followed a significant upward revision in the company's annual net profit forecast. Fujikura raised its guidance to 229 billion yen ($1.42 billion), a substantial leap from its previous guidance of 156 billion yen.
This optimistic outlook for AI data center materials also benefited Fujikura’s peers. Furukawa Electric saw its shares surge by 15% as the market reacted to the increased demand for high-speed connectivity components required for AI infrastructure.
Geopolitical Uncertainties and Profit Booking Temper Gains
Despite the technological rally, the broader market faced headwinds. The Topix index fell 0.57% to 4,044.96, largely weighed down by banking stocks. Major financial institutions, including Mitsubishi UFJ Financial Group and Mizuho Financial Group, dropped by 2.85% and 4.42%, respectively.
两个主要因素导致了这种谨慎情绪。首先，在有报道称美国与伊朗谈判代表在瑞士的会谈陷入僵局后，中东地区的地缘政治不确定性加剧。大和证券 (Daiwa Securities) 高级策略师 Daisuke Hashizume 指出，潜在停火协议突然出现的不确定性为市场情绪带来了“艰难的前景”。其次，投资者在周末前进行了获利了结，尤其是考虑到美国市场计划在周五休市。
