This paper features a new autoregressive conditional duration (ACD) model which sits within the theoretical framework provided by the recently developed observation-driven time series models by Creal et al. (2013): the generalized autoregressive score (GAS) models. The autoregressive conditional...

We use the All Ordinaries Index and the corresponding Share Price Index futures contract written against the All Ordinaries Index to estimate optimal hedge ratios, adopting several specifications: an ordinary least squares-based model, a vector autoregression, a vector error-correction model and...

This paper considers a new class of time series models called autoregressive conditional duration (ACD) models. These models have been developed and applied to investigate the price discovery process in the context of financial markets. The various statistical properties of this class of ACD...

We consider a new class of time series models (introduced by Engle & Russell 1998) used in statistical applications in finance. These models treat the time between events (durations) as a stochastic process and the corresponding durations are modelled using a theory similar to that of...

This paper models the time between trades of the after-hours electronically traded equity futures market, a market which is previously unstudied in this regard. Using a relatively long 2 year data set, trades in the NASDAQ and S&P500 equity futures are shown to require different forms of...

Market participants who want to trade “quickly” demand transactional liquidity. Market participants who demand to trade “immediately” demand transactional immediacy. Traders supply immediacy when the trading returns are high and demand immediacy when the trading returns are low. Traders...

This paper is the first to present a two-stage peer group benchmarking approach to evaluate the performance of hedge funds. We present different ways of orthogonalizing the peer group benchark and discuss their propperties in general. We propose to orthogonalize the benchmark against all other...

"Investors seeking exposure to global equity markets commonly buy international mutual funds managed by locally based fund managers. How competitive is this form of intermediated investing? We investigate whether international equity fund managers mimic each other's portfolio holdings and...

We analyze minute by minute equity price data from 1 August 2005 to 31 October 2008 to study the relationship between the three sources of systematic risk in Fama and French's (1993) model and the market's expectation of total risk as represented by the VIX (the “fear factor”). Our findings...
