Joint Implied Willow Tree: An Approach for Joint S&P 500/VIX Calibration
ABSTRACT Since the inception of Volatility Index (VIX) options trading, academic literature has persistently sought accurate methods for jointly calibrating the prices of the S&P 500 index (SPX) and VIX options. This study introduces a novel nonparametric approach, called the joint implied willow tree (JIWT) method, aimed at resolving this joint ...

A Relation between Short-Term and Long-Term Arbitrage [PDF]
In this work a relation between a measure of short-term arbitrage in the market and the excess growth of portfolios as a notion of long-term arbitrage is established. The former originates from "Geometric Arbitrage Theory" and the latter from "Stochastic Portfolio Theory". Both aim to describe non-equilibrium effects in financial markets.

ABSTRACT In this paper, we investigate alternative one‐factor and two‐factor continuous‐time models with both affine and non‐affine variance dynamics for the Chinese options market. Through extensive empirical analysis of the option panel fit and diagnostics, we find that it is necessary to include both the non‐affine feature and the multi‐factor ...

The Term Structure of Credit Default Swap Spreads and the Cross Section of Options Returns
ABSTRACT This paper, using the natural logarithmic form credit default swap (log CDS) slope, examines the variation in cross‐sectional 1‐month ATM delta‐hedged straddle returns. Our analysis reveals that the log CDS slope significantly and positively predicts these returns, even when accounting for several key volatility mispricing factors.

Asymptotic arbitrage in the Heston model [PDF]
In the context of the Heston model, we establish a precise link between the set of equivalent martingale measures, the ergodicity of the underlying variance process and the concept of asymptotic arbitrage proposed in Kabanov-Kramkov and in Follmer ...

Narrowing the no-arbitrage bounds [PDF]
It is shown by example and by analytic argument that the no-arbitrage bounds can be narrowed by ruling out arbitrages between asset markets and stochastic production opportunities. The key analytic construct is the derivative-cost function. The narrowed noarbitrage bounds can be calculated either as directional derivatives of the derivative-cost ...
