The Volume-Synchronized Probability of Informed trading (VPIN) metric is introduced by Easley, Lopez de Prado, and O'Hara (2011a) as a real-time indicator of order flow toxicity. They find the measure useful in monitoring order flow imbalances and conclude it may help signal impending market...

This research investigates the short-term nature of movements in price data. The key finding of the study is that asset returns do not evolve at the Gaussian increments commonly assumed by continuous pricing models. Instead, prices exhibit strong autocorrelation, often resulting in predictable...

Using the introduction of Arrowhead low latency trading platform by Tokyo Stock Exchange as a natural experiment, I analyze the impact of high frequency trading on market quality of J-REITs, in terms of liquidity, volatility, and systemic risks. I also analyze the impact of the 2008 financial...

As algorithmic trading (AT) has become a dominant component in financial markets, it is important to understand its benefits and costs. We find that AT is positively related to future stock price crash risk and managers’ bad news hoarding behavior. Additional analyses show that the effect of...

In 2010, the Tokyo Stock Exchange, the largest stock exchange headquartered outside of the United States, introduced a new trading platform, Arrowhead. This platform was designed to reduce latency and increase co-located, high-frequency quoting and trading (HFQ) from zero to 36% of trading...

This contribution addresses the impact of high-frequency electronic liquidity provision strategies on financial markets' intraday dynamics, by evaluating the interaction between multiple trading strategies within a computer laboratory, i.e. an artificial stock market. Initially, a realistic...

This paper examines the relationship between systemic risk measures across 546 financial institutions in major petroleum-based economies and oil movements. In this paper, we follow two steps. In the first step, we estimate the delta conditional VaR (CoVaR) for the financial institutions and...

This paper examines the relationship between oil price movements and systemic risk of many financial institutions in major petroleum-based economies. We estimate ΔCoVaR for those institutions and thereby observe the presence of elevated increases in the levels corresponding to the subprime and...

Expected Shortfall (ES) is the average return on a risky asset conditional on the return being below some quantile of its distribution, namely its Value-at-Risk (VaR). The Basel III Accord, which will be implemented in the years leading up to 2019, places new attention on ES, but unlike VaR,...

We use the introduction of a fi nancial transaction tax (FTT) in France in 2012 to test competing theories on its impact. We find no support for the idea that an FTT improves market quality by a ffecting the composition of trading volume. Instead, our results are in line with the hypothesis that...
