• Persistent Correlation-Eigenspace Reconfiguration SPY-to-Cash Risk Overlay

  A monthly risk overlay measures persistent rotation in the subdominant correlation eigenspace of a point-in-time large-cap stock universe. When REC improves completed out-of-sample SPY variance forecasts, positive REC readings reduce SPY exposure in favor of cash.

   Pricing and Hedging of Discretely Monitored Asian Options in the Volterra-Heston Model

   Gijs Custers, Sven Karbach, Martin Friesen · ARXIV

   quant relevance 0.96

   The paper develops methods to price and variance-optimally hedge discretely monitored Asian options under a Volterra-Heston stochastic-volatility model. It covers derivatives valuation, hedge design, hedging-error control, and numerical approximations for rough-volatility dynamics.

   Explainable Deep Learning for Price-Trade Dynamics: From Black-Box Forecasts to Effective Parametric Models

   Manuel Naviglio, Fabrizio Lillo · ARXIV

   quant relevance 0.88

   The paper develops an explainable nonlinear model of trade-level returns and signed order flow for market-impact estimation, execution, and short-horizon algorithmic trading. It reports better predictions than a VAR benchmark, not realized strategy performance, and the platform lacks the required trade- and quote-level inputs.

   Unbiased Monte Carlo Greeks for Discontinuous Payoffs

   Evgeny Lakshtanov · ARXIV

   quant relevance 0.82

   The paper presents a derivatives-pricing and risk-hedging method that corrects pathwise Monte Carlo Greeks for discontinuous exotic payoffs. It applies to exotic-option valuation and delta and vega risk management, but the platform lacks the historical OTC barrier and autocallable contract data needed for a meaningful backtest.
