About

Quant Finance Lab Kagoshima (QFLK) is an independent research initiative focused on volatility dynamics, market structure, and tail risk in financial markets.

Our work combines quantitative analysis, statistical modeling, and structural interpretation to better understand how volatility evolves across assets, sectors, and market regimes.

A central theme of our research is the Volatility Pressure Index (VPI), a simple measure designed to capture the directional pressure underlying changes in variance. Through this framework, we study how local stress accumulates, how structural imbalance emerges, and how tail events may develop.

QFLK aims to provide a rigorous yet accessible perspective on market dynamics, bridging ideas from quantitative finance, risk analysis, and law-like interpretations of variance behavior.

Independent quantitative research based in Kagoshima, Japan.
