Estimating the Value-at-Risk from High-frequency Data
Data augmentation Gibbs sampler Quadratic variation Time changed Brownian motion
2016/1/27
We present two alternative approaches for estimating VaR. Both approaches are based on the observation that each trading day is very diverse and we can observe K different phases of the trading day. W...
Analyzing the Spectrum of Asset Returns: Jump and Volatility Components in High Frequency Data
Analyzing the Spectrum Asset Returns Jump Volatility Components High Frequency Data
2014/3/13
This paper reports some of the recent developments in the econometric analysis of semimartingales estimated using high frequency financial returns. It describes a simple yet powerful methodology to de...

In this paper we extend the market-making models with inventory constraints of Avellaneda andStoikov (High-frequency trading in a limit-order book, Quantitative Finance Vol.8 No.3 2008) and Gueant, L...
Optimal High Frequency Trading in a Pro-Rata Microstructure with Predictive Information
Market making limit order book pro-rata microstructure inventory risk marked point process stochastic control
2012/6/4
We propose a framework to study optimal trading policies in a one-tick pro-rata limit order book, as typically arises in short-term interest rate futures contracts. The high-frequency trader has the c...

Using high-frequency time series of stock prices and share volumes sizes from January 2002-May 2009, this paper investigates whether the effects of the onset of high-frequency trading, most prominent...
Vast Volatility Matrix Estimation using High Frequency Data for Portfolio Selection
Minimum variance portfolio portfolio allocation risk assessment
2010/10/20
Portfolio allocation with gross-exposure constraint is an effective method to increase the efficiency and stability of selected portfolios among a vast pool of assets, as demonstrated in Fan et al (20...

Semimartingale Brownian motion jumps finite activity infinite activity discrete sampling high frequency
2014/3/13
This paper considers the problem of testing for the presence of a continuous part in a semimartingale sampled at high frequency. We provide two tests, one where the null hypothesis is that a continuou...
