Japan Stock Crowding Exceeds July 2024 Rout Levels: Foreign Positions +20%, Retail Margin +35%, Yen Risk
Positioning in Japanese equities is now more crowded than before the July 2024 rout, when the TOPIX tumbled 24% from its record. Foreign net positions are over 20% higher, while retail margin balances have climbed 35% to near a five-year high. Hedge fund allocations to Japan sit at the 99th percentile of the past five years. TOPIX and Nikkei 225 are up 37% and 53% from July 11, 2024, lifted by banking, metals, electronics and AI exporters, but many names remain below their 200-day moving averages. The macro backdrop has shifted, with the 10-year JGB yield near 3% on fiscal sustainability doubts, yet USD/JPY implied volatility is low, indicating almost no pricing of a sudden yen spike.
From July to August 2024, the TOPIX index fell 24% from its all-time high.
Equity positioning is more crowded now than before the July 2024 sell-off. Foreign net positions exceed pre-crash levels by more than 20%, and retail margin balances have climbed 35% from July 2024, hovering near a five-year high. Hedge funds’ total and net allocations to Japan as a share of their global portfolios sit at the 99th and 98th percentile of the past five years, respectively. Gains have been highly concentrated: TOPIX and the Nikkei 225 are up 37% and 53%, respectively, from July 11, 2024, yet a large number of constituents remain below their 200-day moving averages. The indices have been driven higher by banks, steel, non-ferrous metals, electronics, and AI-related exporters. The Nikkei/TOPIX ratio has widened to a historically high 18 times, and the median valuation of AI-related stocks is nearly double that of non-AI stocks.
The macro environment of yen weakness differs from 2024. Since the second half of 2025, when the Liberal Democratic Party lost the upper house election and the Sanae Takaichi administration took power, markets have grown skeptical about Japan's fiscal sustainability, pushing the 10-year Japanese government bond yield toward 3%. One-month USD/JPY implied volatility is relatively low, and the market has priced in almost no risk of a sudden yen appreciation.
