We assess the microstructure of the U.S. Treasury securities market following its migration to electronic trading. We model price discovery using a vector autoregression model of price and order flow. We show that both trades and limit orders affect price dynamics, suggesting that traders also...

This paper compares performances of bid-ask spread measures and analyzes bond-level characteristics' effects on the bid-ask spread for Turkish sovereign bonds traded in Borsa Istanbul. We use intraday order data to establish a relative quoted bid-ask spread as a benchmark and compare bid-ask...

Using a market model and principal component analysis, we investigate the existence of common effects in order imbalance in the Borsa Istanbul's option market. Accordingly, we find the presence of commonality in order imbalance for call options and an even more dominant presence in put options....

This paper combines dimensional analysis, leverage neutrality, and a principle of market microstructure invariance to derive scaling laws expressing transaction costs functions, bid-ask spreads, bet sizes, number of bets, and other financial variables in terms of dollar trading volume and...

This article analyzed the presence of long memory in volatility in 5 Asian equity indices namely SENSEX, CNIA, NIKKEI225, KO11 and FTSTI, using 5 minutes intraday return series ranging from 05-jan-2015 to 06-Aug-2015. The study employed ARFIMA-FIGARCH model and ARFIMA-APARCH model and compared...

Using high frequency data from the London Stock Exchange (LSE), we investigate the relationship between informed trading and the price impact of block trades on intraday and inter-day basis. Price impact of block trades is stronger during the first hour of trading; this is consistent with the...

We derive invariance relationships in a dynamic, infinite-horizon, equilibrium model of adverse selection with risk-neutral informed traders, noise traders, market makers, and with endogenous information production. The model solution depends on two state variables: stock price and...

We study return predictability using a model of speculative trading among relatively overconfident competitive traders who agree to disagree about the precision of their private information. Although traders apply Bayes Law consistently, returns are predictable. In addition to trading on...

Cross-asset market activity can be a channel through which illiquidity risks originating in one market can propagate to others. This paper examines the complex intra-day linkages between the U.S. equity securities market and the equity derivatives market using high-frequency data on S&P 500...

This paper examines the relationship between information asymmetry and stock returns in Borsa İstanbul. For all stocks that are traded in Borsa İstanbul between March 2005 and April 2017, we estimate the probability of informed trading (PIN) by Duarte and Young (2009) factorization and a...
