Beyond Gamma Exposure: Four-Lens Framework for Options Trader Who See What GEX Misses

MPRA Paper from University Library of Munich, Germany

Abstract: Dealer gamma exposure (GEX) has become the dominant retail and semi-institutional framework for interpreting equity index dynamics. This paper argues that GEX carries a quantifiable 30-50% error margin and fails systematically in four market configurations: sovereign crises, physical commodity squeezes, geopolitical commodity shocks, and currency peg breaks. We propose a four-lens framework: (1) Gamma, (2) Vega Exposure, (3) Risk Reversal 25-delta, and (4) Term Structure and Physical Signals. The decision rule is confluence: when three of four lenses align, the signal is actionable. The framework is validated against five publicly documented, time-stamped calls on X (formerly Twitter) prior to major market dislocations. Working paper adapted from: CrossVol Research (2026).
