Read abstract →**Edge hypothesis:** Factor premiums (momentum, value, carry, volatility) are *asset-class-agnostic* risk compensations, but their implementation requires standardized microstructure adjustment. A unified framework that: - Normalizes signals within asset-class contexts (equities ≠ commodities ≠ crypto in liquidity, leverage, and regime sensitivity) - Applies macro regime filtering to reduce drawdowns during factor…
Read abstract →The application of gravitational physics analogies to financial markets has emerged as a conceptually rich but empirically contested framework. The core proposition—that market capitalization functions as mass, correlation distance as gravitational distance, and portfolio construction benefits from gravity-weighted proximity metrics—rests on formal mathematical isomorphism between inverse-square force laws and correlation decay. However, the provided literature reveals that…
Read abstract →**Edge hypothesis:** Momentum signals decay at predictable, measurable rates that vary systematically by asset class, market cap, volatility regime, and sector. By quantifying this decay curve and estimating signal half-life, a trader can: - **Exit winners dynamically** rather than at fixed rebalance dates - **Right-size positions** based on remaining alpha (exponential decay…
Read abstract →This strategy exploits **manager skill heterogeneity** within the institutional investor universe by dynamically selecting subsets of 13F filers whose recent performance justifies following, rather than treating all disclosed positions equally. The core edge rests on three…
Read abstract →The thesis that financial instruments with isomorphic payoff-morphism structures constitute structurally equivalent hedges rests on a fundamental categorical principle: two objects are equivalent if they have identical relational structure within a bounded system, regardless of their material substrate. This synthesis develops a rigorous categorical framework for cross-asset hedging, grounded in the Yoneda Lemma and the theory of natural transformations, and connects it…
Read abstract →This strategy exploits the hypothesis that financial markets exhibit **gravity-like clustering** around market-cap-weighted equilibrium positions, where assets separated by large correlation distances (network-theoretic measures of dissimilarity) represent mean-reversion opportunities. The edge rests on three…
Read abstract →This strategy exploits the hypothesis that assets occupying structurally equivalent positions within financial networks—defined by similar correlation neighborhoods, institutional ownership patterns, or market microstructure roles—exhibit isomorphic payoff relationships. The core insight is that structural equivalence in network topology should produce more stable, lower-basis-risk hedges than traditional correlation-based pairing, because the equivalence captures deeper…
