Does Implied Volatility Imply Volatility—in Bonds?

The Journal of Fixed Income, 2001
The authors investigate the relationship between the implied volatility derived from option contracts on U.S. Treasury bond futures and the actual volatility observed in these securities. Research has suggested that implied volatility in stock options correctly forecasts realized volatility in stock prices; the authors find the same is true in bonds ...

Credit Implied Volatility

SSRN Electronic Journal, 2015
The pricing of corporate credit can be succinctly understood via the credit-implied volatility (CIV) surface. We invert it each month from the firm-by-maturity panel of CDS spreads via the Merton model, transforming CDS spreads into units of asset volatility. The CIV surface facilitates direct comparison of credit spreads at different "moneyness" (firm

AN EXPLICIT IMPLIED VOLATILITY FORMULA

International Journal of Theoretical and Applied Finance, 2017
We show that an explicit approximate implied volatility formula can be obtained from a Black–Scholes formula approximation that is 2% accurate. The relative error of the approximate implied volatility is uniformly bounded for options with any moneyness and with arbitrary large or small option maturities and volatilities, including for long dated ...

Recovering Implied Volatility

Management Science
We propose a methodology for estimating option-implied, forward-looking variances and covariances of assets and portfolios, which may not possess actively traded options. Our approach relies on the observation that, if asset returns follow a factor structure, then the variances and covariances of the factors span the systematic variances and ...

THE ROLE OF IMPLIED VOLATILITY IN VOLATILITY COMBINING FORECASTS

International Journal of Economics and Business Research, 2023
This study explores the role of implied volatility (IV) in volatility combining forecasts for S&P 500 and DAX markets. A range of GARCH models, ad hoc models and STES models were developed to identify the best performing model that served as a base model for subsequent combining process, of which GJRGARCH model appeared to be the superior model among ...

ASYMPTOTICS OF IMPLIED VOLATILITY IN LOCAL VOLATILITY MODELS

Mathematical Finance, 2010
Using an expansion of the transition density function of a one‐dimensional time inhomogeneous diffusion, we obtain the first‐ and second‐order terms in the short time asymptotics of European call option prices. The method described can be generalized to any order.
