The recent introduction of the realized variance measure defined as the sum of the squared intra-daily returns stamped on some high frequency basis has spurred the research in the field of volatility modeling and forecasting into new directions. First, the realized variance is a much better...

Trades in DAX index options with identical maturities cluster around particular classes of strike prices. For example, options with strikes ending on 50 are less traded than options with strikes ending on 00. Clustering is higher when options with close strike prices are good substitutes. The...

In this paper we propose and estimate an econometric model for the distribution of trading activity across options written on the DAX index. The model is based on the observation that in this market options with strike prices ending on 000, 200, 400, 600 and 800 (the class of 200-strike options)...

In this paper a number of alternative autoregressive conditional duration (ACD) models are compared using a sample of data for three major companies traded on the Australian Stock Exchange. The comparison is performed by employing the methodology for evaluating density and interval forecasts,...

A common contention is that more liquid financial contracts draw trading volume from contracts for which they are close substitutes. This paper tests this hypothesis by analyzing clustering of trading activity in DAX index options. Contracts with identical maturities cluster around particular...

More liquid financial contracts are claimed to draw trading volume from contracts for which they are close substitutes. We provide the first analysis of how trading volume across existing financial contracts is affected by changes in the factors that govern the degree to which they are...

It is a well established empirical fact that volatility follows approxi- mately an inverted U-shaped pattern during the day. It is high in the morning, gradually decreasing, reaching a minimum at lunch time and then starting to increase again until the end of the trading day. In this paper we...
