Limit order book,anonymity and market liquidity: evidence from the Sydney Futures Exchange

This study examines the impact of the removal of broker mnemonics on the Sydney Futures Exchange. Early research finds that a decrease in transparency reduces liquidity in the market, whereas more recent research finds that reduced transparency improves market quality. Results of the present study indicate an improvement in liquidity after the removal of broker mnemonics. There is a significant increase in quoted depth and trading volume, and a significant decrease in quoted spreads in the 90 day Bank Accepted Bill, 3 year Treasury Bond and 10 year Treasury Bond Futures. This improvement in liquidity is robust to the length of the event window around the structural change and trading in a control market.

Common liquidity shocks and market collapse: Lessons from the market for perps

We show how a high degree of commonality in investor liquidity shocks can diminish incentives for intermediaries to keep markets open and lead to market collapse, even without information asymmetry or news affecting fundamentals. We motivate our model using the perpetual floating-rate note market where two years of explosive growth – in which issues by high quality borrowers were placed with institutional investors and traded in a liquid secondary market – were followed by a precipitous collapse when market intermediaries withdrew due to large order imbalances. We shed new light on the trade-off between ownership concentration and market liquidity.     

Funding liquidity and equity liquidity in the subprime crisis period: Evidence from the ETF market

Using index and financial exchange-traded funds (ETFs), this study explores the relation between funding liquidity and equity liquidity during the subprime crisis period. Our empirical results show that a higher degree of funding illiquidity leads to an increase in bid–ask spread and a reduction in both market depth and net buying imbalance. Such findings indicate that an increase in funding liquidity can improve equity liquidity, with a stronger effect for the financial ETFs than for the index ETFs. Our study provides a better overall understanding of the effect of the liquidity–supplier funding constraint during the subprime crisis period.     

Financial crisis and stock market efficiency: Empirical evidence from Asian countries

This paper empirically investigates the effects of the 1997 financial crisis on the efficiency of eight Asian stock markets, applying the rolling bicorrelation test statistics for the three sub-periods of pre-crisis, crisis, and post-crisis. On a country-by-country basis, the results demonstrate that the crisis adversely affected the efficiency of most Asian stock markets, with Hong Kong being the hardest hit, followed by the Philippines, Malaysia, Singapore, Thailand and Korea. However, most of these markets recovered in the post-crisis period in terms of improved market efficiency. Given that the evidence of nonlinear serial dependencies indicates equilibrium deviation resulted from external shocks, the present findings of higher inefficiency during the crisis are not surprising as in the chaotic financial environment at that time, investors would overreact not only to local news, but also to news originating in the other markets, especially when the news events were adverse.     

Liquidity,liquidity risk,and information flow: Lessons from an emerging market

This paper examines the role of public and private information flows in intraday liquidity and intraday liquidity risk in the Tunisian stock market. Our empirical results are based on ARMA and GARCH-type models and show that, for major Tunisian stocks, gradually elapsed public information together with gradually elapsed private information in the market is the dominant factor in liquidity improvements in the Tunisian stock market. Liquidity improvements are generated by a decrease in the bid-ask spread accompanied by an increase in the depth at best limit. Our results clearly indicate that the arrival of public information in a sequential manner is the dominant factor generating increases in liquidity risk related to the bid-ask spread, while the advent of private information in a contemporaneous manner is the dominant factor generating increases in liquidity risk related to the depth at best limit. Additionally, our results show that liquidity risk persistence disappears when trading volume and order imbalance are included as explanatory variables in the conditional variance equation.     

Market liquidity risk factor and financial market anomalies: Evidence from the Chinese stock market

The Chinese stock market is an order-driven market and hence its characteristics are structurally different from quote-driven markets. There are no studies that consider the role of the market liquidity risk factor in determining cross-sectional stock returns in a model including financial market anomalies for order-driven markets. Our aim is to test whether financial market anomalies such as firm size, the book-to-market ratio, the turnover rate, and momentum both with and without the inclusion of the market liquidity risk factor in the case of the Chinese stock market can explain cross-sectional stock returns. The empirical framework is based on the model proposed by Avramov and Chordia (AC, 2006). Our main finding is that the AC model can capture financial market anomalies except momentum when we include the market liquidity risk factor on the Chinese stock market.     

The liquidity effects associated with addition of a stock to the S&P 500 index: evidence from bid/ask spreads

This study examines changes in stock liquidity, as measured by the bid/ask spread, when a stock is added to the S&P 500 Index. The paper presents evidence of a significant decrease in the bid/ask spread upon S&P 500 addition, however, this effect is limited to only those stocks that were not trading listed options. Further, the decrease in the bid/ask spread for nonoptioned stocks is accompanied by a significant and permanent increase in share price and trading volume. While optioned stocks experience a permanent increase in trading volume, they experience only a temporary increase in share price. The findings for optioned stocks support the hypothesis that the price and volume effects associated with S&P 500 addition derive from temporary price pressure. Findings pertaining to the nonoptioned stocks indicate that the price and volume effects associated with S&P addition reflect enhanced stock liquidity. The decrease in the bid/ask spread for nonoptioned stocks is attributed to informational efficiencies achieved via index arbitrage trading, and it is argued that this effect is mitigated for optioned stocks due to the pre-existence of arbitrage trading between the option and the underlying stock.     

The relationship between implied and realized volatility: evidence from the Australian stock index option market

This paper examines the relationship between the volatility implied in option prices and the subsequently realized volatility by using the S&P/ASX 200 index options (XJO) traded on the Australian Stock Exchange (ASX) during a period of 5 years. Unlike stock index options such as the S&P 100 index options in the US market, the S&P/ASX 200 index options are traded infrequently and in low volumes, and have a long maturity cycle. Thus an errors-in-variables problem for measurement of implied volatility is more likely to exist. After accounting for this problem by instrumental variable method, it is found that both call and put implied volatilities are superior to historical volatility in forecasting future realized volatility. Moreover, implied call volatility is nearly an unbiased forecast of future volatility.

Consumer attitudes,stock market liquidity,and the macro economy: A Canadian perspective

This study addresses the impact of equity market liquidity on Canadian economic growth and investigates how consumer attitudes/sentiments affect the dynamic macro-liquidity relationship. Using various market liquidity proxies (e.g., illiquidity ratio and open interest of equity futures) while controlling for a specific set of variables, we obtain the following main results: we document the predictability role of liquidity on future economic growth, and we find that during periods of high exchange-rate volatility between the Canadian and US dollars, growth becomes highly affected by stock-market liquidity movements. Furthermore, there is some evidence that stock market liquidity contains additional information for estimating the future state of the economy but is conditional on periods of higher positive consumer attitudes—specifically, consumer confidence in the economy. Additionally, we find strong evidence consistently supporting the premise that a positive change in general consumer sentiment exhibits a direct and significant effect on some macro-economic variables including personal consumption, consumer credit, and economic growth.     

The rationality of early exercise decisions: evidence from the S&P 100 index options market

This study provides a comprehensive empirical analysis of theearly exercise history of S&P 100 put and call option. Eventhough the S&P 100 index option market is generally consideredto be the most efficient options market in the world, we showthat many exercise decisions are inefficient because they occurwhen recorded bids are greater than exercise values. Due tomarket imperfections, some of the cases of inefficient exerciseare still rational, but we show that a substantial number ofthese decisions are clearly irrational since it would have beenpossible to realize a larger riskless net cash flow by selling.Unlike previous studies of early exercise, our tests of efficiencyand the rational decisions that presumably lead to efficientmarkets are model independent. We also provide evidence concerningthe relative significance of dividends and the wild card toindex option pricing models, and introduce and document theimportance of the option to exercise and avoid the indirectcosts of the spread. We also find evidence of a significantday-of the-week exercise effect, and present some likely explanationsfor that effect.     

Bond market access and acquisitions: empirical evidence from the European market

We investigate whether access to bond markets affects acquisition activity of the European firms between 1999 and 2014. Our study provides insight into the effect that the growing European bond market has on corporate investment activity. We find that access to the bond markets, measured by the existence of a credit rating, has a significant effect on the tendency of firms to make acquisitions. The effect is strongest in Continental Europe and during times of high acquisition activity. We further find that consistent with prior U.S. evidence, bond market access has an inverse effect on abnormal returns generated by the acquisitions. That finding suggests that firms with superior access to financing pursue targets of lesser quality.     

The impact of central clearing on counterparty risk,liquidity, and trading: Evidence from the credit default swap market

This paper examines the impact of central clearing on the credit default swap (CDS) market using a sample of voluntarily cleared single-name contracts. Consistent with central clearing reducing counterparty risk, CDS spreads increase around the commencement of central clearing and are lower than settlement spreads published by the central clearinghouse. Furthermore, the relation between CDS spreads and dealer credit risk weakens after central clearing begins, suggesting a lowering of systemic risk. These findings are robust to controls for frictions in both CDS and bond markets. Finally, matched sample analysis reveals that the increased post-trade transparency following central clearing is associated with an improvement in liquidity and trading activity.     

Audit results,market reactions and accounting conservatism: evidence from China

This paper examines China's securities market reactions to publication of the audits of state-owned companies. The impact of audit reports on accounting conservatism is also discussed. Recommendations are made for improving the current system.     

Underwriter reputation and underpricing: evidence from the Australian IPO market

Dimovski and Brooks (J Intern Financ Mark Inst Money 14:267–280, 2004b) examined 358 Australian industrial and mining company initial public offerings (IPOs) from 1994 to 1999 to report that more money was left on the table by IPOs that engaged underwriters than those that did not engage underwriters. Loughran and Ritter (Autumn 5–37, 2004) suggested that the negative relation between underwriter reputation and underpricing has reversed in the 1990s with U.S. IPOs. The main purpose of this paper is to study the relationship between underwriter reputation and underpricing in terms of Australian IPO data. In this paper, we use 380 Australian industrial company IPOs from 1994 to 2004 to perform the empirical study. Our results suggest that more prestigious underwriters are associated with a higher level of underpricing. Other variables that are found to be significant in explaining the level of IPO underpricing are market sentiment, share options, total capital raised and underwriter options.     

Financial liberalisation, foreign aid, and capital mobility: evidence from 90 developing countries

The methodology of Feldstein and Horioka (Econ. J. 90 (1980) 314) is used to gauge the degree of capital mobility and accessibility to international financial markets following financial liberalisation. The sample consists of 90 developing countries divided into four regions: Africa, Asia, Latin America, and the Middle East. The sample period is 1975–1995, split into two periods. Our results indicate that for developing countries capital is relatively immobile. There is also evidence that access to international financial markets increases following financial liberalisation. Finally, including foreign aid in the saving–investment regression has an important positive effect on the saving coefficient.     

Pricing mortgage insurance contracts under housing price cycles with jump risk: evidence from the U.K. housing market

Previous studies have investigated the determinants of housing price cycles in the housing market; however, we observed the phenomenon of housing price jumps in the 2007 subprime crisis. This paper presents a discussion on the housing price cycle and abnormal price jumps to describe the behavior of housing prices in the United Kingdom. The empirical results show that the impact factors of housing cycles are market risk and the switching factor. Furthermore, the impact factors of jump risks include the bursting of the housing bubble and financial crises. Therefore, in this paper, we employ the Markov switching model with jump risks to value the MI contracts and analyze the influences of housing price cycles, jump risks, risks of market interest rate, and the prepayment risks on MI premiums. The results of sensitivity analysis show that more volatile housing price index returns, as well as longer periods of higher volatility in housing prices, raise MI premiums. Moreover, the MI premium is positively related to the absolute value of the average jump amplitude and the shock frequency of abnormal events. There is the tradeoff between the market interest rate and the prepayment risk. The influences of market interest rate are different on MI premium with/without prepayment risks.     

Banks’ intraday liquidity management during operational outages: Theory and evidence from the UK payment system

We investigate how settlement banks in the United Kingdom’s large-value payment system deal with intraday liquidity and operational risk. In particular, we are interested in payments behaviour towards a bank that is, for operational reasons, unable to make but able to receive payments. If other banks did not sufficiently monitor their outgoing payments, these operational shocks could impact the entire payment system because the affected bank could absorb liquidity from the system. Our game-theoretic model predicts that only early in the day, when they are uncertain about the payment instructions they might have to execute, banks stop sending payments to a counterparty which is unable to make payments. Using a non-parametric method, we find that this prediction is supported by the data, implying that banks effectively contain the disruption caused by the operational outage: payment flows between healthy banks remain unaffected.     

Markowitz efficiency and size effect: evidence from the UK stock market

Academics and practitioners have frequently debated the relationship between market capitalization and expected return. We apply the Markowitz efficient frontier approach to develop a portfolio performance measure that compares the return of a portfolio to its optimal return, using data from the UK stock market over the period 1985–2012. Our results show that there is a negative relationship between portfolio size and portfolio return during the period under study. When comparing actual portfolio return with achievable return for the same level of risk, we find that as the portfolio size expands, underperformance of the portfolio increases, i.e. the larger the portfolio size, the greater the underperformance. This indicates that Markowitz efficiency is difficult to achieve, particularly in large portfolios. Changing model parameters leads to alternative efficient frontiers that impact upon the measurement of performance. However, the use of alternative efficient frontiers does not affect our result of the size effect on the relative performance of portfolios. Our study shows that the size effect is present over the full period. Our findings also suggest that the excess returns found in small portfolios are likely to be associated with higher levels of diversifiable risk in comparison with larger portfolios. Furthermore, in contrast to other studies, we find no evidence to support the size reversal effect in the data.
