Citigroup believes the bull market in Japanese stocks is not over, significantly raising its target for the Nikkei 225 index to 90,000 points. The supporting rationale extends beyond monetary easing to include enhanced corporate pricing power, improved profit margins, rising ROE, and continued global liquidity providing conditions for a valuation re-rating.
According to reports, in its July 1st Japanese equity strategy report, strategist Ryota Sakagami maintained the TOPIX target at 4,500 points while lifting the Nikkei 225 target to 90,000 points. This represents a significant upward revision from the "breakthrough 70,000 points before year-end" and high-point estimate of 72,000 points in the June 2nd report, indicating continued target increases even after substantial market gains.
Over the past month, Japanese equities extended their advance, with TOPIX surpassing 4,000 points and the Nikkei 225 rising above 72,000 points. An uptick in US long-term rates triggered a pullback in early June, but subsequent progress in Middle East peace talks, stabilizing US Treasury yields, and a smooth Bank of Japan meeting helped push stocks back onto an upward trajectory.
For investors, the key takeaway from this target upgrade is not simply chasing the index, but confirming the market's primary focus remains on high-growth, high-momentum, and high-beta assets. Technology stocks remain the core variable behind the Nikkei 225 target revision, with concurrent upward revisions to earnings expectations preventing them from entering typical bubble territory.
From 70,000 to 90,000: Upside from Earnings and Valuation Re-rating
On June 2nd, Citigroup's Japan equity strategy team noted that while Japanese stocks might see a short-term peak, significant upside potential remained through year-end, and there was no need to alter the fundamentally bullish view. At that time, they concurrently raised the TOPIX target to 4,500 points, corresponding to a 17.5x P/E ratio and an EPS forecast of 258.4 yen for the fiscal year ending March 2028, and estimated a Nikkei 225 high of 72,000 points, expecting it to break 70,000 before year-end.
A month later, with the market nearing or exceeding the previous Nikkei 225 high estimate, the report further raised the target to 90,000 points. Ryota Sakagami wrote in the July 1st strategy update that the bullish view on Japanese equities remains unchanged, supported by margin improvements from price pass-through, rising ROE, and ample global liquidity. Assuming the tech-led bull market continues, the TOPIX target is maintained at 4,500 points, and the Nikkei 225 target is raised to 90,000 points.
This indicates the framework for bullishness on Japanese stocks hasn't fundamentally changed; market validation has simply been faster than previously anticipated. The primary reasons for raising the Nikkei 225 target are upward revisions to tech sector earnings expectations and the index's structural advantages. Maintaining the TOPIX target suggests the overall corporate earnings and ROE improvement path remains stable.
Price Pass-Through as a Foundational Driver: Corporate Pricing Power Boosts Margins
The first core logic is the enhanced ability of Japanese firms to pass on costs.
Historically, Japanese companies long lacked pricing power, with cost increases often directly compressing profit margins. The current shift sees companies more actively passing import and input costs through to final prices. Improvements in output prices for large firms correlate positively with improvements in operating profit margins.
This feeds directly into earnings forecasts. The TOPIX EPS base case shows FY26E EPS at 234.9 yen, up 11.5% year-over-year; FY27E at 261.4 yen, up 11.3%; and FY28E at 291.6 yen, up 11.5%. Concurrently, ROE rises from 10.3% in FY26E to 11.6% in FY28E.
Therefore, maintaining the TOPIX target at 4,500 points does not rely solely on valuation multiple expansion. It emphasizes continuous improvements in earnings and ROE. With the current TOPIX 12-month forward ROE at 10.3% and P/B at 1.76x, there remains room for re-rating within this framework.
The Bank of Japan Factor: Rate Hikes Aren't the Issue, Absence of Surprises Is Key
Monetary policy is not the sole basis for bullishness on Japanese stocks, but the smooth outcome of the Bank of Japan meeting reduced market disruptions.
On June 16th, the Bank of Japan raised the policy rate from 0.75% to 1.0% and decided to stop reducing the scale of long-term Japanese government bond purchases from April 2027. Both decisions aligned with prior media reports, avoiding additional market shocks.
For equities, the most favorable combination is not "never raising rates," but rather monetary conditions remaining relatively accommodative while avoiding sharp volatility in exchange rates and long-term interest rates. This meeting fell within that range. The rate hike magnitude was digestible, and the bond purchase arrangement prevented long-term rates from spiraling.
The Bank of Japan also acknowledged that companies are more actively passing cost increases to prices, aligning with the corporate profit improvement thesis. As long as rate hikes remain gradual, the path for ~10% corporate earnings growth remains intact.
The Key Bet: Continuation of Tech Sector Earnings
The Nikkei 225's outperformance relative to TOPIX stems primarily from its higher weighting in technology stocks. As tech stocks surged rapidly, bubble concerns naturally arose, but earnings expectations were revised upward concurrently, preventing stock prices from entering a typical bubble zone relative to earnings forecasts.
Calculations suggest that if tech stock prices merely followed current consensus EPS expectations, they would still have a slightly over 20% outperformance margin relative to TOPIX. This corresponds to approximately 10% upside for TOPIX and about 30% absolute upside for the tech sector. A Nikkei 225-to-TOPIX N/T ratio nearing 20x is not an unreasonable assumption under this framework, leading to the Nikkei 225 target being raised to 90,000 points.
The primary risk to this view stems from global data center investment. The fundamental driver of earnings improvement for Japanese tech firms is increased global data center capital expenditure. If data center investment undergoes a correction, Japanese corporate earnings could also be revised downward.
However, under current path assumptions, while hyperscale cloud providers may slow their capex growth rate, the probability of an outright capex cut remains low. As long as capital expenditure continues to grow, Japanese tech sector EPS does not appear to have peaked. Short-term adjustments are therefore more likely to be mid-cycle volatility rather than a signal of the bull market's end.
Factor Performance: High Momentum, Growth, and Beta Remain in Favor
Year-to-date, factor performance in the Japanese market has been straightforward. The 3-month, 6-month, and 12-month momentum factors have been notably effective; the value factor has been weak overall, with negative contributions from P/E and dividend yield; earnings growth and upward earnings revisions have contributed positively; and high-beta, high-volatility stocks have delivered significant returns.
This is not solely a tech stock phenomenon. Even after excluding AI and semiconductor-related stocks, TOPIX as a whole exhibits similar characteristics. This indicates the Japanese market is not trading on a single theme but rather a broad shift in market risk appetite towards high-growth, high-momentum stocks.
Within the tech sector, a key metric is the PEG ratio. In the overall tech sector where valuations are already elevated, the PEG ratio remains effective, indicating capital is not indiscriminately chasing highs but is seeking companies whose earnings growth sufficiently justifies their valuations. In other words, the focus in tech stock selection is not low P/E, but whether growth can digest the valuation.
During this phase of Japanese equity gains, high-beta and high-volatility stocks tend to outperform more easily. Since March, the contribution from the high-beta factor has strengthened further, but this also implies increased portfolio risk exposure. When long/short funds chase returns, they can push risk levels too high. The logic for low-beta stocks differs. Citigroup suggests the high-beta segment is better screened using growth and momentum, while in low-beta defensive stocks, the value factor contributes more noticeably, with limited momentum influence.
This reflects a change in the valuation framework for defensive stocks. In the 2010s, with overall low corporate profit growth in Japan, defensive stocks offering stable growth commanded a valuation premium. In the 2020s, with overall corporate profit growth rising, defensive stock growth has lagged the market average, leading valuations to shift from a premium to a discount.
