In this paper we utilise the risk factors from both the finance and energy economics literatures to develop an improved asset pricing model (the Augmented-Four-Factor Model or AFFM) in the context of the European energy utility sector. In addition, we undertake inter-sectoral and inter-temporal...

We present a modelling approach for sector asset pricing studies that incorporates sector-level risk factors, sub-group portfolios, and structural break point tests that are better at isolating the time-varying nature and the firm-specific component of returns. The sub-group portfolios show...

We present a modelling approach for sector asset pricing studies that incorporates sector-level risk factors, subgroup portfolios, and structural breakpoint tests that are better at isolating the time-varying nature and the firm-specific component of returns. Our results show considerable...

We present the first evidence of the impact of dark trading on adverse selection in an aggregate market. At moderate levels of dark trading, a positive liquidity effect dominates an information acquisition disincentive effect, such that dark trading induces reductions in both adverse selection...

The quality of ultra-high frequency quotes submitted to an entrant high-tech market (BATS Chi-X Europe – Chi-X) is compared to those of an established national exchange (London Stock Exchange – LSE). There are intraday variations regarding which platform impounds new information about the...

We propose a state-space modeling approach for decomposing trading volume into its liquidity-driven and information-driven components. Using a set of high-frequency S&P 500 stock data, we show that informed trading is linked with a reduction in volatility, illiquidity, and toxicity/adverse...

We investigate the role of price leadership and informed trading in the competition for order flow between high-tech entrant trading venues and established national trading venues. An analysis of BATS Chi-X Europe (Chi-X), a high-tech entrant, and London Stock Exchange (LSE), an established...
