Japan’s Sector Leaders Change with the Cycle but Value Holds Steady
Japan is emerging from decades of low inflation and deflation, and nominal growth and policy rates are moving in a direction many Japan investors have not encountered in years. Examining historical patterns may help investors understand the current environment’s impact on sector and factor returns. Based on data since the 1970s, we analyzed average monthly gross active returns1 for MSCI Japan sector and factor indexes against the MSCI Japan Index across four macro regimes: Goldilocks, Heating Up, Slow Growth and Stagflation.
Sector leadership changed hands with regimes
Goldilocks, the most common regime in the sample, favored information technology which added 1.5% a month in active return.2 Japan’s technology sector is concentrated in semiconductors and hardware, which have been exposed to successive cycles of global electronics demand, from PCs in the late 1990s through smartphone components and now AI infrastructure.
Heating Up produced a sharp divergence across sectors. Financials gained 1.4% while communication services lost 1%, consistent with higher interest rates supporting banks and insurers while telecom operators — under policy pressure to cut mobile tariffs — lost ground to rising discount rates. Slow Growth reordered the market again: Defensive sectors (health care and energy) led active returns, while real estate lagged the most.
Enhanced value was the only factor that paid in every regime
Factors dispersed far less than sectors on average. Enhanced value posted positive active returns in all four regimes — the only factor to do so — and its returns varied less across regimes than those of any other factor. No factor detracted in Slow Growth, but defensive factors like high dividend yield and quality led. When nominal growth was slowing, cash returns and balance-sheet strength carried the load. Quality gave back 0.8% in Heating Up, as reflation rewarded the leveraged balance sheets that Quality tends to underweight.
Mapping sector and factor exposures back to the regimes in which they performed could give allocators a sharper lens on their portfolio’s macro dependence.
Average monthly gross active return in JPY relative to the MSCI Japan Index, in percentage points. Sample periods vary by sector and factor and reflect the longest history available for each. For sectors, the sample period is from January 1995 to June 2026, except communication services and real estate, which begin in June 1997 and September 2016 respectively. For factors, the sample period is from July 1994 to June 2026, except minimum volatility, enhanced value and growth target, which start in June 1988, December 1997 and June 1999 respectively. Regime classification covers every month from 1973 onward; active returns are measured only over the periods listed above. Regimes are defined on Japanese growth and inflation momentum. Goldilocks pairs rising growth with easing inflation, Heating Up pairs rising growth with rising inflation, Slow Growth pairs falling growth with easing inflation and Stagflation pairs falling growth with rising inflation.

What Does History Tell Us About Factor Investing in Japan?
High Dividend Yield and Enhanced Value, Japan's strongest factors over 25+ years, delivered similar returns to the U.S. with less risk. Pairing factors improved outcomes even further.
Factor and Sector Behavior Across Macro Regimes
Over the last nearly 50 years, changes in interest rates have had a more pronounced impact on the performance of factor and sector indexes than the rate level itself. Insights from these findings may be helpful in realigning portfolios to a shifting macro view.
1 Average active returns describe what happened in a regime but may need additional analysis. Short regime windows may result in wide sampling error, so we placed a two-sided 95% confidence interval around every index and regime cell and applied a Benjamini-Hochberg false discovery rate correction across these tests. Five sector cells cleared the threshold: information technology in Goldilocks, financials in Heating Up, health care in Slow Growth and Stagflation, and communication services in Stagflation. Enhanced Value was the only index significant over the full sample yet significant in no single regime, consistent with a small, persistent edge rather than a regime-specific one. Quality was significant and negative in Heating Up but significant and positive in Slow Growth, and Minimum Volatility was significant and negative in Goldilocks but significant and positive in Stagflation. High Dividend Yield cleared in both Slow Growth and Stagflation.
2 From December 1973 to June 2026, Goldilocks represented 34% of the sample period followed by Stagflation (26%), Slow Growth (24%) and Heating Up (16%).
