In this work a modification of the Box-Tiao methodology for the assessment of the impact of external events on time series is proposed as an alternative statistical approach of assessing the predictive performance of the moving average trading rule in financial markets. With the proposed...

The authors explore the risk-return properties of simple momentum strategies in six major government-bond markets and find that trend-following investment rules generate positive information ratios in the 1987-2011 sample period. They simulate the combination of momentum portfolios with...

This paper proposes a modified version of the widely used price and moving average cross-over trading strategies. The suggested approach (presented in its 'long only' version) is a combination of cross-over 'buy' signals and a dynamic threshold value which acts as a dynamic trailing stop. The...

We examine the impact of trading on markets partially exempt from National Market System requirements (‘dark venues') on equity market quality. We find evidence consistent with the notion that dark venues rely on their special features to segregate order flow based on asymmetric information...

A unique data set from NASDAQ OMX Nordic allows a deep analysis of trader types' activity and provides evidence on the roles played in the trading ecosystem. We specifically investigate the impact of algorithmic traders on market quality relative to the activities of other market participants...

Numerous studies in the finance literature have investigated technical analysis to determine its validity as an investment tool. This study is an attempt to explore whether some forms of technical analysis can predict stock price movement and make excess profits based on certain trading rules in...

We investigate the aggregate market quality impact of equity shares that fail to deliver (hereafter “FTDs”). For a sample of 1,492 NYSE stocks over a 42-month period from 2005 to 2008, greater FTDs lead to higher liquidity and pricing efficiency, and their impact is similar to our estimate...

We study the effects that the ban on short sales of shares in financial firms introduced in late 2008 and removed early 2009 had on the microstructure and the quality of UK equity markets. We show that the ban did nothing to affect order flows: financial stocks were being more aggressively sold...

We analyze how market fragmentation affects market quality of SME and other less actively traded stocks. Compared to large stocks, they are less likely to be traded on multiple venues and show, if at all, low levels of fragmentation. Concerning the impact of fragmentation on market quality, we...

Exchange traded funds (ETFs) that track a specified index are a financial technology that has risen dramatically in the last two decades. We model an ETF's optimal index replication strategy and show that it involves underweighting or omitting illiquid index assets. Instrumenting for ETF trading...
