We use an agent-based approach to model trading behaviour in high-frequency markets. This study focuses on the Foreign Exchange (FX) market. The initial part of this study is to observe the micro-behaviour of traders to define the... more
We examine the relationship between volatility and past and future returns using high-frequency aggregate equity index data. Consistent with a prolonged leverage effect, we find the correlations between absolute high-frequency returns... more
Growth forecasts are at the heart of investment decisions and yet in emerging and developing markets they often receive limited support from quantitative models. This paper describes the main quantitative modelling techniques that have... more
Modeling and forecasting the volatility of Brazilian asset returns: a realized
After excluding countries with high-inflation crisesperiods and Long-Run Growth when annual inflation is above 40 percentthe data reveal no evidence of a Michael Bruno William Easterly consistent relationship between growth and inflation,... more
Analyzing co-movements in equity markets is important for risk diversification in portfolio management. Copulas have several advantages compared to the linear correlation measure in modeling co-movement. This paper introduces a copula... more
With the availability of intra-daily price data, researchers have focused more attention on market microstructure issues to understand and help formulate strategies for the timing of trades. The purpose of this article is to provide a... more
The sum of squared intraday returns provides an unbiased and almost errorfree measure of ex-post volatility. In this paper we develop a nonlinear Autoregressive Fractionally Integrated Moving Average (ARFIMA) model for realized... more
Spot foreign exchange market today is the most volatile and liquid of all financial markets in the world. The present paper addresses in details the efficiency, liquidity and risk seen by a trader, particularly concentrating on analysis... more
This report covers the important topic of stochastic volatility modelling with an emphasis on linear state models. The approach taken focuses on comparing models based on their ability to flt the data and their forecasting performance. To... more
Lake Analyzer is a numerical code coupled with supporting visualization tools for determining indices of mixing and stratification that are critical to the biogeochemical cycles of lakes and reservoirs. Stability indices, including Lake... more
Statistical arbitrage strategies, such as pairs trading and its generalizations, rely on the construction of mean-reverting spreads enjoying a certain degree of predictability.
The goal of this paper is twofold. First, using five of the most actively traded stocks in the Brazilian financial market, this paper shows that the normality assumption commonly used in the risk management area to describe the... more
The objective of this paper is to investigate the use of tick-by-tick data for market risk measurement. We propose an Intraday Value at Risk (IVaR) at different horizons based on irregularly time-spaced high-frequency data by using an... more
This paper evaluates the performance of conditional variance models using high-frequency data of the National Stock Index (S&P CNX NIFTY) and attempts to determine the optimal sampling frequency for the best daily volatility forecast. A... more
The increased episodes of the financial crises throughout the world in the 1990s motivated research interests to identify the channels through which such crises spread from one country to the entire region and across regions and to... more
This article examines the impact of serial correlation in high frequency returns on the realized variance measure. In particular, it is shown that the realized variance measure yields a biased estimate of the conditional return variance... more
In this work we deal with the design and simulation of a complete multi-carrier modem alternative to the recommended one (single-carrier) for the high frequency data link standard (known as HFDL) for communications between ground stations... more
Analyzing co-movements in equity markets is important for risk diversification in portfolio management. Copulas have several advantages compared to the linear correlation measure in modeling co-movement. This paper introduces a copula... more
A rapidly growing literature has documented important improvements in financial return volatility measurement and forecasting via use of realized variation measures constructed from high-frequency returns coupled with simple modeling... more
This paper uses high-frequency data to examine the relation between official and free-market exchange rates in Albania. We use daily data to test econometrically, first, whether the official and free markets are efficient, in the sense... more

Stylised facts for univariate high-frequency data in finance are well-known. They include scaling behaviour, volatility clustering, heavy tails, and seasonalities. The multivariate problem, however, has scarcely been addressed up to now.
It is generally believed that for the power of unit root tests, only the time span and not the observation frequency matters. In this paper we show that the observation frequency does matter when the high-frequency data display fat tails... more
A rapidly growing literature has documented important improvements in volatility measurement and forecasting performance through the use of realized volatilities constructed from highfrequency returns coupled with relatively simple... more
We show how pre-averaging can be applied to the problem of measuring the ex-post covariance of financial asset returns under microstructure noise and non-synchronous trading. A pre-averaged realised covariance is proposed, and we present... more

We consider the problem of deriving an empirical measure of daily integrated variance (IV) in the situation where high-frequency price data are unavailable for part of the day.

The causal impact of algorithmic trading (AT) on market quality is difficult to establish due to endogeneity bias. We address this problem by using the introduction of co-location as an exogenous event after which AT increased. Matching... more
In this paper we propose a new lossless image compression method. The suggested method relies on novel selective scan process that aims to scan the image in the direction where minimal pixel intensity change is recorded. Such scan process... more

Using a data set consisting of three years of 5-minute intraday stock index returns for major European stock indices and U.S. macroeconomic surprises, the conditional mean and volatility behaviors in European market were investigated. The... more
This paper characterizes the temporal pattern of trading rule returns and official intervention for Australian, German, Swiss and U.S. data to investigate whether intervention generates technical trading rule profits. High frequency data... more
