Using Machine Learning to Predict Realized Variance [PDF]

open access: green, 2019
In this paper we formulate a regression problem to predict realized volatility by using option price data and enhance VIX-styled volatility indices' predictability and liquidity. We test algorithms including regularized regression and machine learning methods such as Feedforward Neural Networks (FNN) on S&P 500 Index and its option data.

Development of high-frequency volatility estimators in pricing and trading stock options

open access: yesπ-Economy, 2022
Asset return volatility plays a key role in derivative pricing and hedging, risk management and portfolio allocation decisions. This study examined the economic benefit of high-frequency volatility estimators (measures realized) in option pricing and ...

Modelling temporal dependence of realized variances with vines [PDF]

open access: greenEconometrics and Statistics, 2019
Abstract Models for realized volatility that take the specific form of temporal dependence into account are proposed. Current popular methods use the idea of mixed frequencies for forecasting realized volatility, but neglect the potential non-linear and non-monotonic temporal dependence.

Estimating quadratic variation using realized variance [PDF]

open access: yesJournal of Applied Econometrics, 2002
AbstractThis paper looks at some recent work on estimating quadratic variation using realized variance (RV)—that is, sums ofMsquared returns. This econometrics has been motivated by the advent of the common availability of high‐frequency financial return data. When the underlying process is a semimartingale we recall the fundamental result that RV is a

A Note on Forecasting the Historical Realized Variance of Oil-Price Movements: The Role of Gold-to-Silver and Gold-to-Platinum Price Ratios

open access: yesEnergies, 2021
We examine the predictive value of gold-to-silver and gold-to-platinum price ratios, as proxies for global risks affecting the realized variance (RV) of oil-price movements, using monthly data over the longest available periods of 1915:01–2021:03 and ...

Lasso-Based Forecast Combinations for Forecasting Realized Variances [PDF]

open access: yesSSRN Electronic Journal, 2016
Volatility forecasts are key inputs in financial analysis. While lasso based forecasts have shown to perform well in many applications, their use to obtain volatility forecasts has not yet received much attention in the literature. Lasso estimators produce parsimonious forecast models.

Properties of Bias-Corrected Realized Variance Under Alternative Sampling Schemes [PDF]

open access: greenJournal of Financial Econometrics, 2005
In this article I study the statistical properties of a bias-corrected realized variance measure when high-frequency asset prices are contaminated with market microstructure noise. The analysis is based on a pure jump process for asset prices and explicitly distinguishes among different sampling schemes, including calendar time, business time, and ...
