Abstract

Purpose

The purpose of this paper is to explore the impact of institutional trading on the market quality during the financial crisis and short sale ban.

Design/methodology/approach

The following methods was applied to discuss the total impact on market quality and efficiency of short sale ban in USA from 2001 to 2010. The author examined institutional ownership and breadth of ownership while performing a mean variance tests for changes in efficiency as well as multivariate analysis.

Findings

Analyzing USA, Standard and Poor’s 500 stocks the author find increase high-low volatility, realized volatility, effective spread and relative quoted spread during January 1, 2007 to December 31, 2010. Realized volatility increases for both small and large quantile stocks. High-low volatility increases for small quantile stocks and relative quoted spread increases for large quantile stocks. Comparing the percentage change between pre and climax period we find that large quantile stocks have a negative association between breadth of institutional ownership and returns and a positive relation high-low volatility, realized effective spread and quoted spread to returns.

Originality/value

The present paper is the first to discuss the total impact on market quality and efficiency of short sale ban in USA from 2001 to 2010. The author find a remarkable improvement in market efficiency (variance ratios) after the crisis period for small and non-financial stocks, while the price efficiency lost during the crisis period is more persistent for large and financial stocks.

Abstract

Purpose

The purpose of this paper is to study price discovery and price convergence in securities trading within a fragmented market environment where stocks are traded on multiple venues. The results provide novel empirical insights questioning the generalizability of the current literature and aim to expand the understanding of price determination in a fragmented market microstructure.

Design/methodology/approach

This paper provides an empirical data analysis based on an event study methodology. The authors applied Thomson Reuters Tick History data covering German blue chip stocks listed on multiple venues in 2009 and 2013. Different time aggregations up to one second are applied to provide an in-depth analysis.

Findings

The paper empirically discovers a persistent price leader-follower relationship not only during intraday auctions but also in subsequent continuous trading. The authors found that trading on alternative venues instantly dries out in case the dominant market switches to a call auction. In these situations, alternative markets await and adopt the official price signal of the dominant market although prices on alternative venues still indicate a certain extent of price discovery. This phenomenon remains persistent at different levels of market fragmentation, indicating that alternative trading venues fully accept the price leadership role of the dominant market, no matter their own market share.

Originality/value

This paper provides an innovative empirical setup to analyze price co-movement and convergence based on high-frequent data. Further, the results provide novel and robust insights into the price determination process in fragmented markets that clarify the role of price follower and price leader.

Abstract

Purpose

The purpose of this paper is to investigate the immediate impact of firm-specific announcements on the trading volume of individual and institutional investors on the Australian Securities Exchange (ASX), during a period when the market becomes fragmented.

Design/methodology/approach

This study uses intraday trading volume data in five-minute intervals prior to and after firm-specific announcements to measure individual and institutional abnormal volume. There are 70 such intervals per trading day and 254 trading days in the sample period. The first 10 minutes of trading (from 10.00 to 10.10 a.m.) is excluded to avoid the effect of opening auction and to ensure consistency in the “starting time” for all stocks. The volume transacted during five-minute intervals is aggregated and attributed to individual or institutional investors using Broker IDs.

Findings

Institutional investors exhibit abnormal trading volume before and after announcements. However, individual investors indicate abnormal trading volume only after announcements. Consistent with outcomes expected from a dividend washing strategy, abnormal trading volume around dividend announcements is statistically insignificant. Both individual and institutional investors’ buy volumes are higher than sell volumes before and after scheduled and unscheduled announcements.

Research limitations/implications

The study is Australian focused, but the results are applicable to other limit order book markets of similar design.

Practical implications

The results add to the understanding of individual and institutional investors’ trading behaviour around firm-specific announcements in a securities market with continuous disclosure.

Social implications

The results add to the understanding of individual and institutional investors’ trading behaviour around firm-specific announcements in a securities market with continuous disclosure.

Originality/value

These results will help regulators to design markets that are less predatory on individual investors.

Abstract

Purpose

The purpose of this paper is to investigate the impact of short selling and margin trading on the price discovery and price informativeness of cross-listed firms, using a sample of Chinese firms listed on the China and Hong Kong stock exchanges.

Design/methodology/approach

The sample consists of 67 Chinese cross-listed firms on A-share and H-share markets out of which 18 firms are allowed to be sold short/ traded on margin since March 2010. Using pre- and post-event period, the authors compare and contrast various market microstructure variables. The contributions of the home (A-share) and overseas (H-share) markets to the incorporation of new information into prices are calculated following the permanent-transitory approach of Gonzalo and Granger (1995) as well as the adverse selection component of Lin et al. (1995).

Findings

The findings indicate that for the group of Chinese cross-listed firms that are not allowed to be sold short or bought on margin, the home (A-share) market contributes more to the price discovery process over time. However, for the group of cross-listed firms that are eligible for short selling and margin trading, the authors observe no significant difference in the contribution of either A- or H-share markets to the price discovery. The contribution of home market for these firms is even lower around the announcement of major events. The authors further find that while the short sale activities appears to be informative, measured by the adverse selection (AS) component of spread, on the whole they have not led the A-share markets to be more informative.

Research limitations/implications

The sample of cross-listed Chinese firms that are allowed to be sold short or bought on margin are rather limited. Hence, the results should be read with some caution.

Practical implications

The removal of short selling constraints appears to improve the contribution of the respective markets to the process price discovery, in the case for larger cross-listed firms.

Originality/value

The authors shed new lights on how the introduction of short selling and margin trading impacts on the price discovery of the Chinese cross-listed firms. A further contribution of the study is the use of high frequency data, while most of the previous studies on the Chinese markets use daily data.

Abstract

Purpose

The purpose of this paper is to examine the changes in the price impact of trades in the major Korean stock market following the introduction of disclosure to all traders of the top five brokers on the buy-side and the top five brokers on the sell-side of trades in real time for each stock in the KOSDAQ market.

Design/methodology/approach

The paper uses several alternative metrics for the price impact of trades. The study applies estimation methodology that accounts for the potential endogeneity of other market quality proxies, which are used as control variables in price impact regressions, by utilizing two-stage-least-square methods with fixed effect specification.

Findings

This study finds that the permanent price impact (information effect) of both buyer- and seller-initiated trades increases, which indicates that information is disseminated quicker in a transparent market. Uninformed trades have a larger permanent price impact than informed trades on both the buy and sell sides. The liquidity price effects are found to be mixed for buys and sells.

Research limitations/implications

The study supports the current policy of the Korean Exchange to publicly display the five most active broker IDs on both the buy and sell sides, as it attracts both informed and liquidity traders, leading to faster price discovery in a more transparent market. However, a future study which analyzes the change in the market quality in both local markets would provide a complete picture of the effects of the policy.

Originality/value

Earlier studies documenting the effect of broker ID disclosure on market quality used effective spreads, market depth or order book imbalance as market quality measures. This study contributes to the existing literature by examining the changes in direct measures of the private information effect and liquidity effect of trades in a stock market – the Korean Stock Exchange – when the other part of the exchange (the KOSDAQ stock market) shifts to public broker ID transparency at the same transparency level.
