The Nikkei 225 ended a historic week on a volatile note, shedding 1.21% on Friday to close at 56,941.97. While the index successfully tested uncharted territory earlier in the week—surging past 58,000 for the first time—renewed global anxieties regarding the valuation of the technology sector triggered a wave of profit-taking ahead of the weekend.

The 58,000 Resistance Test

The defining narrative of the week was the index’s aggressive test of the 58,000 level. Fueled by a mid-week rally that saw the index touch a 52-week high of 58,015.08, bullish sentiment initially appeared dominant. This surge was largely driven by foreign capital inflows betting on the continuation of the “Takaichi Trade”—a market rally underpinned by the Prime Minister’s pro-growth fiscal policies. However, as the chart indicates, the breakout was short-lived. The inability to sustain a close above this psychological ceiling suggests that technical resistance remains formidable, with traders opting to lock in gains rather than chase prices at record valuations.

Sector Spotlight: The AI Reality Check

Friday’s decline was not broad-based selling but rather a targeted correction in the high-flying technology sector. SoftBank Group, often viewed as a bellwether for AI sentiment in Tokyo, slumped nearly 9%, dragging the wider index lower. This move mirrored a similar risk-off sentiment on Wall Street, where investors have begun scrutinizing the sustainability of massive AI capital expenditures.

Conversely, the market displayed significant nuance. Kioxia Holdings bucked the trend, surging nearly 8% on the back of robust quarterly results and recovering NAND flash prices. For investors, this divergence highlights a critical shift: the market is moving from buying “general AI themes” to rewarding companies with tangible earnings growth.

Global & Local Headwinds

Beyond the corporate ticker tape, macroeconomic factors continue to exert pressure. The Japanese Yen has shown signs of “perkiness,” strengthening slightly as fiscal fears dissipate, which naturally weighs on Japan’s export-heavy index. For the Israeli investor, the correlation between Tel Aviv’s tech-heavy indices and Tokyo’s semiconductor sector is becoming increasingly relevant. The volatility seen in Tokyo this week serves as a leading indicator for global tech valuations, suggesting that the “AI premium” is being reassessed worldwide.

As we look toward next week, the primary question is whether the 56,500 level will hold as a support floor. The market is currently in a consolidation phase, digesting the rapid ascent to 58,000. Investors should monitor upcoming U.S. inflation data and further earnings reports from the semiconductor supply chain. If the support at 56,500 holds, this pullback could be viewed as a healthy consolidation within a longer-term bull market; however, a breach below could signal a deeper correction as global funds reassess their exposure to Asian equities.
