The implied volatility of a sports game [PDF]
Journal of Quantitative Analysis in Sports, 2015 AbstractIn this paper we provide a method for calculating the implied volatility of the outcome of a sports game. We base our analysis on Stern’s stochastic model for the evolution of sports scores (Stern, H. S. 1994. “A Brownian Motion Model for the Progress of Sports Scores.”

Dynamics of Connectedness in Clean Energy Stocks
Energies, 2020 This paper examines the dynamics of connectedness among the realized volatility indices of 16 clean energy stocks belonging to the SPGCE and the implied volatility indices of two important stock markets—the S&P 500 and the STOXX50—and two commodities ...

Forecasting Implied Volatility Surfaces [PDF]
SSRN Electronic Journal, 2008 This paper introduces a new semi-parametric methodology for the implied volatility surface, which incorporates machine learning algorithms. Given a starting model, a tree boosting algorithm sequentially minimizes the residuals of observed and estimated implied volatility.

Volatility has to be rough [PDF]
arXiv, 2020 First, we give an asymptotic expansion of short-dated at-the-money implied volatility that refines the preceding works and proves in particular that non-rough volatility models are inconsistent to a power law of volatility skew. Second, we show that given a power law of volatility skew in an option market, a continuous price dynamics of the underlying ...

A Review of Volatility and Option Pricing [PDF]
arXiv, 2009 The literature on volatility modelling and option pricing is a large and diverse area due to its importance and applications. This paper provides a review of the most significant volatility models and option pricing methods, beginning with constant volatility models up to stochastic volatility. We also survey less commonly known models e.g.

On the Curvature of the Bachelier Implied Volatility
RisksOur aim in this paper is to analytically compute the at-the-money second derivative of the Bachelier implied volatility curve as a function of the strike price for correlated stochastic volatility models.

The Information Content of Corridor Volatility Measures During Calm and Turmoil Periods
Quantitative Finance and Economics, 2017 Measurement of volatility is of paramount importance in finance because of the effects on risk measurement and risk management. Corridor implied volatility measures allow us to disentangle the volatility of positive returns from that of negative returns,

Can there be an explicit formula for implied volatility? [PDF]
arXiv, 2012 It is "well known" that there is no explicit expression for the Black-Scholes implied volatility. We prove that, as a function of underlying, strike, and call price, implied volatility does not belong to the class of D-finite functions. This does not rule out all explicit expressions, but shows that implied volatility does not belong to a certain large

Credit-implied forward volatility and volatility expectations
Finance Research Letters, 2016 AbstractWe show how one can back out implied forward volatility term structures from credit default swap spreads. Such forward stock volatility term structures are useful for instance in forward start option pricing. We find the term structure to be downward-sloping, and the credit market's volatility forecasts tend to vary more across time than across

E-Jurnal Matematika, 2016 Black-Scholes model suggests that volatility is constant or fixed during the life time of the option certainly known. However, this does not fit with what happen in the real market. Therefore, the volatility has to be estimated. Implied Volatility is the
