A simple option pricing model is suggested based on correlation of underlying stock with actual market behavior as reflected by market index, thereby market factor coefficient to enable the traders to quote the prices. The simplicity and ease of the proposed model may appeal to the traders,...

Credit Support Annexes (CSAs) that allow multiple currencies as collateral give rise to a collateral choice option in discounting. Numerical efficiency for valuing this optionality is key and first-order approximations have been proposed previously. In this paper, for the case of two currencies,...

We derive a closed-form expansion of option prices in terms of Black-Scholes prices and higher-order Greeks. We show how the true price of an option less its Black-Scholes price is given by a series of premiums on higher-order risks that are not priced under the Black-Scholes model assumptions....

Paralleling regulatory developments, we devise value-at-risk and expected shortfall type risk measures for the potential losses arising from using misspecified models when pricing and hedging contingent claims. Essentially, losses from model risk correspond to losses realized on a perfectly...

This paper has used the Arbitrage Theorem under binomial case to show that in a complete market with no transaction costs and no arbitrage, for any asset, the current spot price is a function of the risk-free interest rate, the future possible prices and their probabilities. These probabilities...

Equity index risk premia vary more than can be explained by market risks and pricing models. I show that index option intermediaries cause variation in risk premia to manage their option positions. When expected volatility is low, intermediaries hold risky short positions. Increasing risk and...

The paper outlines Monte-Carlo simulation procedures for the pricing of swaptions under the discrete-time arbitrage-free Nelson-Siegel (DTAFNS) model of Eghbalzadeh et al. (2022). In particular, the forward measure dynamics of term structure factors are derived, leading to a semi-analytic...

This paper proposes a linear option pricing model by imposing common market pricing on decentralized risk exposure estimates across option contracts underlying the same security. The model embeds historical moment estimators to anchor the breakeven contribution of each risk source. A...
