The Application of Symbolic Regression on Identifying Implied Volatility Surface

open access: yesMathematics, 2023
One important parameter in the Black–Scholes option pricing model is the implied volatility. Implied volatility surface (IVS) is an important concept in finance that describes the variation of implied volatility across option strike price and time to ...

The surface of implied firm’s asset volatility

open access: yesJournal of Banking and Finance, 2020
This paper analyzes the surface of CDS implied firm's asset volatility at the aggregate market level, using a sample of European investment-grade firms during the 2007-2014 period. The term structure of asset implied volatilities is backed-out from the term structure of CDS spreads, while the moneyness dimension is proxied by the ratio of the default ...

Arbitrage-free smoothing of the implied volatility surface [PDF]

open access: yesQuantitative Finance, 2009
The pricing accuracy and pricing performance of local volatility models crucially depends on absence of arbitrage in the implied volatility surface: an input implied volatility surface that is not arbitrage-free invariably results in negative transition probabilities and/ or negative local volatilities, and ultimately, into mispricings.

Modeling Implied Volatility Surface Using B-Splines with Time-Dependent Coefficients Predicted by Tree-Based Machine Learning Methods

open access: yesMathematics
Implied volatility is known to have a string structure (smile curve) for a given time to maturity and can be captured by the B-spline. The parameters characterizing the curves can change over time, which complicates the modeling of the implied volatility

An Intuitive Introduction to Fractional and Rough Volatilities

open access: yesMathematics, 2021
Here, we review some results of fractional volatility models, where the volatility is driven by fractional Brownian motion (fBm). In these models, the future average volatility is not a process adapted to the underlying filtration, and fBm is not a ...

DSFM Fitting of Implied Volatility Surfaces [PDF]

open access: yes5th International Conference on Intelligent Systems Design and Applications (ISDA'05), 2005
The implied volatility became one of the key issues in modern quantitative finance, since the plain vanilla option prices contain vital information for pricing and hedging of exotic and illiquid options. European plain vanilla options are nowadays widely traded, which results in a great amount of high-dimensional data especially on an intra day level ...

PCA for Implied Volatility Surfaces [PDF]

open access: yesThe Journal of Financial Data Science, 2020
Principal component analysis (PCA) is a useful tool when trying to construct factor models from historical asset returns. For the implied volatilities of U.S. equities there is a PCA-based model with a principal eigenportfolio whose return time series lies close to that of an overarching market factor.

Deep Smoothing of the Implied Volatility Surface [PDF]

open access: yesSSRN Electronic Journal, 2019
We present a neural network (NN) approach to fit and predict implied volatility surfaces (IVSs). Atypically to standard NN applications, financial industry practitioners use such models equally to replicate market prices and to value other financial instruments.
