Fundamental money is still buying Japanese equities, but CTA covering and yen appreciation limit the appeal of chasing gains in the short term
Supply-demand pressure in the AI trade is gradually easing, but the Nikkei remains in a rebound-driven deleveraging environment; near term, investors should watch risks in yen crosses and relatively prefer domestic-demand high beta, domestic-demand value, and specific styles that benefit from yen appreciation.
- Global media attention around an “AI bubble” has fallen from its peak, and short trades in AI semiconductors are also being covered, with overall supply-demand conditions stabilizing.
- CTAs are still reducing long positions in four technology-heavy equity index futures, and the Nikkei has not yet resumed long accumulation; its near-term dip-buying priority lags NDX and TAIEX.
- After USD/JPY fell below the CTA breakeven level of about 158.7, yen shorts may continue to be covered; if fully covered, the downside target for USD/JPY is about 151–153.
- The risk in EUR/JPY is more pronounced, with 176.4 as the key risk threshold; if CTAs cover on a large scale, around 160 may also come into view.
- Macro hedge funds continued to buy Japanese equities on dips in July, with net exposure rising to the highest level since 2017, indicating that their investment rationale is shifting more toward a recovery in Japanese manufacturing rather than relying solely on yen depreciation.
- The impact of the July momentum collapse may extend into the first half of August, and investors are expected to reduce chasing export momentum and high-beta stocks, shifting toward domestic-demand high beta or domestic-demand value stocks.
Report interpretation
Overview
The report evaluates the Japanese market from four dimensions: supply-demand in AI and semiconductor trades, CTA equity-index and FX positioning, macro hedge fund flows, and Japanese equity style factors. Global risk appetite recovered after a dense event period, and overheated AI narratives and related short trades have receded somewhat, but Japan and South Korea remain affected by deleveraging pressure after excessive crowding in prior semiconductor momentum trades. Japanese equities also face a higher risk premium from yen appreciation, although fundamental macro funds are still increasing allocations to Japanese equities, showing that the medium-term thesis has not been undermined.
Core views
The Nikkei is in a rebound-driven deleveraging environment, but about 90% of the previously accumulated futures longs with a breakeven level of around 64,600 have already been closed, so urgent stop-loss pressure may have eased. The current dip-buying order for technology stocks is NDX, TAIEX, NKY, and KOSPI 200, and the Nikkei’s relative appeal remains low. In FX, CTA-held yen shorts are starting to come under pressure; the potential further decline in USD/JPY appears relatively limited, while yen crosses such as EUR/JPY may generate larger yen-appreciation risk. However, global recession concerns, credit spreads, and FX volatility do not show systemic stress, so a large-scale yen short squeeze is not the base case. In style allocation, investors should avoid more volatile external-demand momentum stocks in the short term and prefer domestic-demand high beta or domestic-demand value; if USD/JPY moves further toward 150, export value and domestic-demand quality styles may also improve due to lower input costs and reversals in long-short positioning.
Analysis framework
The research combines theme heat indicators constructed from the number of news reports, CTA trend-following positions and breakeven point simulations, macro fund net exposure, manufacturing PMI, and credit-market stress indicators. It distinguishes external-demand and domestic-demand stocks based on the TSE 33 industry classification, then assesses styles using industry-neutral value, quality, momentum, and beta factor performance as well as exchange-rate sensitivity.
Methodology notes
Constructs an index from the number of global media news reports warning of overheating in the AI market, with January 2023 set to 100.
This indicator is used to mechanically measure the strength of the AI bubble narrative; the report observes that attention has contracted from its peak, but the number of news reports is not equivalent to fundamental valuation or actual fund flows.
Estimates key exchange-rate or index levels based on the cumulative entry costs of trend-following funds and simulates potential target ranges if positions are fully covered.
The report treats USD/JPY around 158.7, EUR/JPY around 184.0, and 176.4 as important positioning thresholds and uses them to assess CTA covering pressure, rather than treating them as fundamental fair values.
Combines U.S. and Japanese credit indices, sovereign credit spreads, FX volatility, and global recession news scores to judge whether yen shorts may experience a systemic squeeze.
Current credit markets are stable and financial stress is low, so the report believes the macro triggers required for large-scale yen short covering have not yet formed.
Compares global macro hedge funds’ net positions in Japanese equities, exchange-rate expectation indicators, and Japan’s manufacturing PMI.
The rise in macro fund net exposure and its alignment with improving manufacturing PMI support the view that their buying is based more on improvement in the domestic operating environment rather than a single bet on yen depreciation.
Mechanically divides domestic-demand and external-demand stocks based on the TSE 33 industry classification, and analyzes value, quality, momentum, and beta factors within the TOPIX 500 and GICS industry-neutral framework.
The report uses factor returns, industry loadings, and historical sensitivities to USD/JPY and EUR/JPY through the end of July 2026 to assess style rotation; historical elasticities are treated only as technical references and cannot be directly regarded as return forecasts.
Asset mapping & comparison
Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).
- Japanese equitiesThe core research subject, jointly affected by AI trade recovery, CTA deleveraging, yen appreciation, and fundamental fund flows.
- Strengths
- Macro hedge funds continue to buy on dips, with net exposure at the highest level since 2017; manufacturing PMI has improved significantly.
- Weaknesses
- The aftershocks of the July momentum collapse have not yet ended, semiconductor optimism has not fully recovered, and the Nikkei remains in a rebound-driven deleveraging environment.
- Comparison
- Its recent relative dip-buying appeal is lower than NDX and TAIEX but higher than KOSPI 200.
- Risks
- Rapid yen appreciation, continued CTA reduction of equity-index longs, and further deleveraging in export momentum and high-beta positions.
- NKYUsed to observe CTA trend positions in Japanese technology and broad equity-index futures.
- Strengths
- About 90% of related longs near the key level have been closed, so urgent stop-loss pressure may have eased.
- Weaknesses
- Below 64,600, it still tends toward selling into rebounds and has not yet resumed long accumulation.
- Comparison
- Its rebound strength and dip-buying priority lag NDX and TAIEX.
- Risks
- If the semiconductor trade weakens again or yen appreciation accelerates, CTAs may continue to reduce positions.
- NDX and TAIEXLeading references for the recovery of global AI and technology trades.
- Strengths
- The rebound is relatively strong, and the related supply-demand structure has not clearly collapsed.
- Weaknesses
- They remain exposed to AI valuation, momentum trades, and semiconductor cycle volatility.
- Comparison
- The report ranks their dip-buying priority ahead of NKY and KOSPI 200.
- Risks
- AI sentiment deteriorates again or crowded technology trades deleverage again.
- USD/JPYThe main exchange rate for assessing CTA yen short covering and its impact on the risk premium of Japanese equities.
- Strengths
- Even if CTA positions are fully covered, the simulated downside target is 151–153, suggesting that further downside in this currency pair alone may be limited.
- Weaknesses
- The spot price is already below the CTA breakeven point of about 158.7, so covering pressure may persist.
- Comparison
- The report believes its yen-appreciation risk is lower than that of crosses such as EUR/JPY.
- Risks
- Post-intervention trend reversal, continued CTA covering, and transmission of FX volatility to Japanese equities.
- EUR/JPYRegarded as a more critical carrier of yen-appreciation risk.
- Strengths
- The current low-financial-stress environment lowers the probability of immediate large-scale covering.
- Weaknesses
- The spot price is already below the estimated breakeven point of about 184.0 and is approaching the more important 176.4 threshold.
- Comparison
- Both the potential magnitude of covering and the risk of driving yen appreciation are higher than USD/JPY.
- Risks
- A break below 176.4 may accelerate CTA covering, with around 160 coming into view in an extreme scenario.
- Japanese domestic-demand high-beta and domestic-demand value stocksRelatively preferred style directions for the first half of August.
- Strengths
- They rely less on external demand and can absorb funds exiting more volatile export momentum stocks.
- Weaknesses
- High-beta domestic-demand stocks may still be affected by a decline in overall risk appetite.
- Comparison
- They are relatively superior to external-demand momentum and external-demand high-beta stocks in the short term.
- Risks
- Rising global market stress, weaker-than-expected domestic economic improvement, or a reversal in style rotation.
- Japanese export value and domestic-demand quality stocksContrarian styles that may regain appeal if USD/JPY moves further toward 150.
- Strengths
- Export value stocks may benefit from lower input costs such as fuel and from covering of long-short positions in external-demand momentum and high beta.
- Weaknesses
- The conclusion that export value benefits from yen appreciation is somewhat counterintuitive and depends on historical elasticities and positioning structures.
- Comparison
- They are not currently mainstream preferences, but may outperform existing crowded styles under a scenario of further yen appreciation.
- Risks
- Historical exchange-rate sensitivities fail, FX translation losses on revenue exceed cost improvements, or global demand weakens.
Key data

- KOSPI 200 reference levelAbove 960The positioning situation is similar to the Nikkei, but its dip-buying priority among the four technology indices is the lowest.
- Technology stock dip-buying priorityNDX, TAIEX, NKY, KOSPI 200The ranking reflects the relative strength of AI trade recovery and supply-demand structures across markets.
- USD/JPY spot price157.6As of August 4, 2026, it was below the estimated breakeven point for CTA yen short positions accumulated since October of the previous year.
- USD/JPY CTA breakeven pointAround 158.7Sustained trading below this level may prompt CTAs to gradually cover yen shorts.
- USD/JPY full-covering simulation range151–153This is the QDS team’s estimate of the downside target under a scenario of full covering of CTA long positions.
- EUR/JPY spot price181.4As of August 4, 2026, it was slightly below the estimated breakeven point of about 184.0 for CTA positions.
- EUR/JPY key risk threshold176.4A break below this level would put it below the average cost of positions built since March 2025 and may accelerate CTA covering.
- EUR/JPY extreme covering reference levelAround 160This corresponds only to a risk scenario of substantial covering of CTA-related long positions and is not a base-case forecast.
- Macro fund Japanese equity net exposureHighest since 2017Macro hedge funds continued to buy Japanese equities on dips in July 2026.
Impact & implications
For Japanese equities, the traditional linear relationship between FX and the stock market is weakening: yen appreciation may still raise export-stock volatility and the market risk premium, but macro funds place greater emphasis on a manufacturing recovery and AI-driven autonomous improvement in business conditions. At the short-term trading level, investors should not directly equate a recovery in global AI sentiment with a trend reversal in Japanese semiconductor stocks, and should wait for CTA equity-index positions to shift back to accumulation. In allocation, investors can relatively prefer domestic-demand high beta and domestic-demand value, and reassess export value and domestic-demand quality styles when USD/JPY approaches 150.
Risks
- CTAs cover positions in USD/JPY and yen crosses in a concentrated manner, causing abnormal yen appreciation and raising the risk premium of Japanese equities.
- EUR/JPY breaking below 176.4 triggers a faster reversal in trend-following positions.
- The deleveraging process from the July AI and semiconductor momentum collapse extends into the second half of August.
- Nikkei and other technology-heavy equity index futures fail to restore CTA long accumulation, and rebounds continue to encounter profit-taking.
- Global recession concerns, credit spreads, or FX volatility suddenly rise, worsening the currently relatively moderate yen-appreciation scenario.
- Improvement in Japan’s manufacturing PMI fails to continue, weakening the fundamental basis for macro funds to increase Japanese equity holdings.
- Style judgments based on historical exchange-rate elasticities fail, and the negative impact of yen appreciation on exporters’ revenue exceeds the positive effect of lower input costs.
What to watch
- Whether NKY can regain a firm footing above 64,600 and shift from CTA deleveraging to long accumulation.
- How long USD/JPY stays below 158.7 and whether it moves toward the 151–153 range.
- Whether EUR/JPY breaks below the key CTA risk threshold of 176.4.
- Whether U.S. and Japanese credit indices, sovereign credit spreads, and FX volatility show rising stress.
- Whether global AI bubble news attention and covering of AI semiconductor shorts continue to improve.
- Relative rebound strength and CTA positioning changes across NDX, TAIEX, NKY, and KOSPI 200.
- Whether macro hedge fund net exposure to Japanese equities remains at historical highs.
- Whether improvement in Japan’s manufacturing PMI can continue and translate into upward revisions to corporate earnings.
- Whether funds rotate from external-demand momentum and high beta toward domestic-demand high beta, domestic-demand value, export value, and domestic-demand quality.
