The Physics of Factor Rotation.
Bridging the gap between academic theory and institutional execution. Our research library provides a rigorous examination of market anomalies, risk premia, and the mathematical frameworks driving modern alpha generation.
Our Research
Manifesto
Last Updated: March 2026
We reject the "black box" philosophy. Factor analysis is most effective when the underlying economic logic is transparent. Our focus is on persistence—identifying market behaviors that survive transaction costs and changing volatility regimes.
Signal-to-Noise Ratio
Every paper published undergoes a rigorous out-of-sample validation process to ensure the identified quant factors are not mere artifacts of data mining.
Contextual Neutrality
We analyze how common equity factors interact with macro variables like interest rate cycles and regional liquidity shifts in the Tokyo market.
The Active Repository
A collection of peer-reviewed insights and internal FujiFactor briefs regarding systematic trading tools and factor modeling.
The Crowdedness Coefficient: Measuring Factor Decay
This study quantifies the impact of institutional capital flows on the Value and Momentum factors over the last 18 months in the Japanese equity market.
Non-Linear Correlations in High-Volatility Regimes
Exploring how traditional factor diversification breaks down during tail events and the role of adaptive hedging tools in protecting quant portfolios.
Synthetic Yield: Factor-Enhanced Carry Strategies
A comprehensive guide to constructing portfolios that blend fundamental carry signals with modern statistical arbitrage overlays.
From Paper to Production
Research at FujiFactor is never a solo endeavor. Our quant team works in direct proximity to our software engineers. This ensures that every factor model we publish is compatible with the low-latency execution tools we build for our partners in Shibuya and beyond.
- Verified backtesting environments using tick-level data.
- Integration-ready code snippets provided with every paper.
- Dynamic updates reflecting the 2026 market regime changes.
Library Fundamentals
01 / Concept
Factor Attribution
The process of decomposing portfolio risk and return into its constituent systematic exposures, such as Size, Momentum, and Quality.
02 / Logic
Smart Beta
Systematic investment strategies that capture specific factor premia through rules-based index construction rather than traditional market-cap weighting.
03 / Math
Cross-Sectional
Analyzing the relative performance of a universe of assets at a single point in time to identify significant factor deviations.
