Highlights:

1. Japan’s broad TOPIX index set a new 52-week high of 3,130.46 on Monday before succumbing to a wave of profit-taking.
2. The index ended the week with a net loss, closing at 3,100.87 after three consecutive days of declines.
3. A modest 0.58% rebound on Friday failed to erase the weekly losses and significantly underperformed strong rallies in Western markets.
4. Investor focus now shifts to whether this pullback is a healthy consolidation or a sign of growing exhaustion in the Japanese bull market.

Japan’s TOPIX index experienced a week of starkly contrasting halves, surging to a fresh 52-week high before a persistent wave of selling pressure erased those gains and pushed the market into negative territory for the week. This retreat from a new peak, which occurred while U.S. markets were staging powerful rallies, highlights a significant divergence in global investor sentiment. The price action suggests that after a prolonged run-up, conviction among investors in Japanese equities may be waning, raising questions about the durability of one of the world’s top-performing markets.

A New Peak Meets a Wall of Selling

The trading week in Tokyo began with a burst of optimism. On Monday, the TOPIX climbed to a new 52-week high of 3,130.46, closing the session strong at 3,120.96. This new peak, however, acted as a clear signal for investors to begin taking profits. Starting Tuesday, the market began a steady three-day descent, with selling pressure accelerating through the mid-week. By Thursday’s close, the index had fallen to 3,082.95, hitting a weekly low of 3,075.81. This classic “peak and retreat” pattern indicates a psychological shift in the market, where the fear of losing recent gains began to outweigh the fear of missing out on further upside.

A Tepid Bounce in a Divergent Market

While global markets ended the week with a surge of risk appetite, the recovery in Tokyo was notably subdued. The TOPIX managed a modest 0.58% gain on Friday, a figure that pales in comparison to the nearly 2% rallies seen across major U.S. indices. This underperformance suggests that the drivers influencing Japanese equities are currently decoupled from those in the West. While U.S. investors shrugged off concerns, traders in Tokyo appeared more focused on domestic factors, such as the future path of Bank of Japan monetary policy, currency fluctuations in the yen, and the sustainability of corporate earnings growth. The weak bounce was not enough to repair the technical damage from the mid-week sell-off.

The Outlook: A Test of Support

Looking ahead, the TOPIX faces a critical test of its long-term uptrend. The immediate challenge for the bulls will be to defend the support level established at the week’s low around 3,075. A failure to hold this line could open the door for a deeper correction as more long-term holders may be tempted to lock in profits. For the rally to resume, the index must first reclaim the ground lost and then mount a convincing assault on the new resistance at the 3,130 peak. Investors will be closely watching for fresh catalysts from either corporate Japan or the central bank to determine if this past week’s retreat was a mere pause or the start of a more significant downturn.
