Liquidity and stock returns: Evidence from a pure order-driven market using a new liquidity proxy

Liquidity has been found to be a determinant of stock returns in large hybrid quote-driven markets. Liquidity proxies have ranged from trade-based measures such as turnover rate to order-based measures such as the bid-ask spread. The relationship between return and liquidity in small pure order-driven markets is less clear, with different liquidity proxies yielding conflicting results. This study adds to the existing literature by considering the return-liquidity relationship on the Australian Stock Exchange, a small pure order-driven market, using a new liquidity measure, Weighted Order Value (WOV). Liquidity is found to be an important determinant of returns.     

Foreign institutional ownership and stock market liquidity: Evidence from Indonesia

From January 2002 to August 2007, foreign institutions held almost 70% of the free-float value of the Indonesian equity market, or 41% of the total market capitalization. Over the same period, liquidity on the Jakarta Stock Exchange improved substantially with the average bid–ask spread more than halved and the average depth more than doubled. In this study we examine the Granger causality between foreign institutional ownership and liquidity, while controlling for persistence in foreign ownership and liquidity measures. We find that foreign holdings have a negative impact on future liquidity: a 10% increase in foreign institutional ownership in the current month is associated with approximately 2% increase in the bid–ask spread, 3% decrease in depth, and 4% rise in price sensitivity in the next month, challenging the view that foreign institutions enhance liquidity in small emerging markets. Our findings are consistent with the negative liquidity impact of institutional investor ownership in developed markets.     

Exchange trading rules and stock market liquidity

We examine stock exchange trading rules for market manipulation, insider trading, and broker–agency conflict, across countries and over time, in 42 stock exchanges around the world. Some stock exchanges have extremely detailed rules that explicitly prohibit specific manipulative practices, but others use less precise and broadly framed rules. We create new indices for market manipulation, insider trading, and broker–agency conflict based on the specific provisions in the trading rules of each stock exchange. We show that differences in exchange trading rules, over time and across markets, significantly affect 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.     

Global liquidity risk in the foreign exchange market

Using a broad data set of 20 US dollar exchange rates and order flow of institutional investors over 14 years, we construct a measure of global liquidity risk in the foreign exchange (FX) market. Our FX liquidity measure may be seen as the analog of the well-known Pastor–Stambaugh liquidity measure for the US stock market. We show that this measure has reasonable properties, and that there is a strong common component in liquidity across currencies. Finally, we provide evidence that liquidity risk is priced in the cross-section of currency returns, and estimate the liquidity risk premium in the FX market around 4.7 percent per annum.     

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.     

Liquidity and asset pricing: Evidence from the Hong Kong stock market

This study investigates the role of liquidity in pricing stock returns in the Hong Kong stock market. Our results show that liquidity is an important factor for pricing returns in Hong Kong after taking well-documented asset pricing factors into consideration. The results are robust to adding portfolio residuals and higher moment factor in the factor models. The results are also robust to seasonality, and conditional-market tests. We also compare alternative factor models and find that the liquidity four-factor model (market excess return, size, book-to-market ratio, and liquidity) is the best model to explain stock returns in the Hong Kong stock market, while the momentum factor is not found to be priced.     

Cross-listing and liquidity in emerging market stocks

In this study, we analyze liquidity costs for stocks and ADRs from the four main Latin American markets. The results indicate that international investors are exposed to different trading costs in Latin America, with market location and firm size as important determinants. In the local market, stocks that cross-list internationally do not always present a liquidity cost advantage relative to non-cross-listed stocks. When the ADR and the local stock markets are compared, large firms present lower trading costs in the home market. The opposite occurs for small firms.     

Stock market liquidity and firm value

This paper investigates the relation between stock liquidity and firm performance. The study shows that firms with liquid stocks have better performance as measured by the firm market-to-book ratio. This result is robust to the inclusion of industry or firm fixed effects, a control for idiosyncratic risk, a control for endogenous liquidity using two-stage least squares, and the use of alternative measures of liquidity. To identify the causal effect of liquidity on firm performance, we study an exogenous shock to liquidity—the decimalization of stock trading—and show that the increase in liquidity around decimalization improves firm performance. The causes of liquidity's beneficial effect are investigated: Liquidity increases the information content of market prices and of performance-sensitive managerial compensation. Finally, momentum trading, analyst coverage, investor overreaction, and the effect of liquidity on discount rates or expected returns do not appear to drive the results.     

Uncertainty,market structure,and liquidity

In this study we show that market uncertainty [measured by the Chicago Board Options Exchange Market Volatility Index (VIX)] exerts a large market-wide impact on liquidity, which gives rise to co-movements in individual asset liquidity. The effect of VIX on stock liquidity is greater than the combined effects of all other common determinants of stock liquidity. We show that the uncertainty elasticity of liquidity (UEL: percent change in liquidity given a 1% change in VIX) has increased around regulatory changes in the US markets that increased the role of public traders in liquidity provision, reduced the minimum allowable price variation, weakened the affirmative obligation of NASDAQ dealers, and abolished the specialist system on the NYSE.     

Understanding commonality in liquidity around the world

We examine how commonality in liquidity varies across countries and over time in ways related to supply determinants (funding liquidity of financial intermediaries) and demand determinants (correlated trading behavior of international and institutional investors, incentives to trade individual securities, and investor sentiment) of liquidity. Commonality in liquidity is greater in countries with and during times of high market volatility (especially, large market declines), greater presence of international investors, and more correlated trading activity. Our evidence is more reliably consistent with demand-side explanations and challenges the ability of the funding liquidity hypothesis to help us understand important aspects of financial market liquidity around the world, even during the recent financial crisis.     

Stock market development under globalization: Whither the gains from reforms?

Over the past decades, many countries have implemented significant reforms (including financial liberalization, privatization, and regulatory and supervisory improvements) to foster domestic capital market development. Despite these policies, the performance of capital markets in several countries has been disappointing. To understand the effects of reforms, we study the impact of six capital market reforms on domestic stock market development and internationalization. We find that reforms tend to be followed by increases in domestic market capitalization and trading. But reforms are also followed by an increase in the share of activity in international equity markets, with potential negative spillover effects.     

The impacts of standard monetary and budgetary policies on liquidity and financial markets: International evidence from the credit freeze crisis

This paper evaluates the domestic and international impacts of lowering short-term interest rates and increasing budget spending on several indicators of liquidity, volatility, credit and economic activity. Data from the 2003–2011 period in the United States, the Euro zone and Canada were used to develop two SVAR models for assessing the national effectiveness and the international spillovers of monetary and budgetary policies during the credit freeze crisis. While monetary policies caused a temporary decrease in volatility and increase in liquidity in North American stock markets, the shocks were mainly domestic and ineffective at generating liquidity in the banking sector. In contrast, government spending shocks had a positive impact on credit and consumption, especially in Europe and Canada. Moreover, budgetary policies also had a positive international spillover effect on consumption and credit, especially for smaller economies such as Canada.     

Multimarket trading and corporate bond liquidity

Global bonds are international securities traded and settled efficiently in multiple markets. This paper examines global bonds to evaluate the effects of multimarket trading on corporate bond liquidity and pricing. The results show that global bonds are significantly more liquid than similar-sized domestic bonds of the same issuers, and their liquidity advantage is reflected in higher market valuations. These findings support microstructure models that predict a positive relation between the number of potential investors and liquidity in over-the-counter markets, and help explain the increasing use of global bonds by corporate issuers.     

Systematic liquidity risk and stock price reaction to shocks

This study examines the relationship between systematic liquidity risk and stock price reaction to large 1‐day price changes (or shocks). We base our analysis on a yearly updated constituents list of the FTSE All share index. Our overall results are consistent with the price continuation hypothesis, which suggests that positive (negative) shocks will be followed by positive (negative) abnormal returns. However, further analysis indicates that stocks with low systematic liquidity risk react efficiently to both positive and negative shocks, whereas stocks with high systematic liquidity risk underreact to both positive and negative shocks. Our results are valid irrespective of various robustness tests such as size of the shock, size of the firm, month‐of‐the‐year and day‐of‐the‐week effects. We conclude that trading on price patterns following shocks may not be profitable, as it involves taking substantial liquidity exposure.     

Short sales and speed of price adjustment: Evidence from the Hong Kong stock market

We present empirical evidence that short sales contribute to market efficiency by increasing the speed of price adjustment to not only private/public firm-specific information but also market-wide information. Shortable stocks are characterized by weaker trade continuity and stronger quote reversals. They adjust faster to new information than non-shortable counterparts. These findings remain robust even in an “up” market condition in which short sales are not binding. The amount of information incorporated in each trade is also significantly higher for shortable than non-shortable stocks in both “up” and “down” market conditions. After controlling for firm size, trading volume, liquidity, price and option trading, short sales stand out as one of the significant factors that speed up the price adjustment.     

The world price of liquidity risk

This paper empirically tests the liquidity-adjusted capital asset pricing model of Acharya and Pedersen (2005) on a global level. Consistent with the model, I find evidence that liquidity risks are priced independently of market risk in international financial markets. That is, a security’s required rate of return depends on the covariance of its own liquidity with aggregate local market liquidity, as well as the covariance of its own liquidity with local and global market returns. I also show that the US market is an important driving force of global liquidity risk. Furthermore, I find that the pricing of liquidity risk varies across countries according to geographic, economic, and political environments. The findings show that the systematic dimension of liquidity provides implications for international portfolio diversification.     

Short-term patterns in government bond returns following market shocks: International evidence

We employ government bond portfolios from 17 countries in order to investigate the short-run reaction of investors to price shocks. Our findings indicate a uniform return reversal pattern across countries, that persists irrespective of various robustness tests such as different datasets (Datastream/J.P. Morgan), different maturity bands, and day-of-the-week effects. Simulated trading strategies based on our results suggest that this pattern can be employed to generate economically significant profits for many country portfolios. We also demonstrate that significant zero-investment profits are possible even when instead of the expensive to replicate country bond portfolios we employ directly tradable and low transactions cost instruments, such as Bond Futures Contracts.     

Pricing currency risk in the stock market: Evidence from Finland and Sweden 1970-2009

We investigate the role of currency risk on stock markets in two interlinked Nordic countries exhibiting a gradual move from fixed to floating exchange rates. We apply the Ding and Engle (2001) covariance stationary specification in a multivariate GARCH-M setup to test a conditional international asset pricing model. Using a sample period from 1970 to 2009, we find that the currency risk is priced in both stock markets, and that the price and the risk premium are lower after the floatation of the currencies, especially for Finland. We also find the cross-country exchange rate shock from Finland to affect the price of currency risk in Sweden, but not vice versa. Finally, we discuss some of the potential issues in applying multivariate GARCH-M specifications in tests of asset pricing models.     

The dynamics of privatization, the legal environment and stock market development

In this paper, we examine under which conditions privatization is an effective means to develop local stock markets for a panel of 61 countries over the last twenty four years. By addressing the endogeneity between privatization and stock market development, we show for the 1980-98 period that the initial legal environment is a significant contemporary determinant of stock market development, while privatization is not. When we examine the dynamics of privatization in interaction with the legal environment, we find that privatization has a two-year-lagged effect on stock market development in emerging markets, and a one-year-lagged effect in developed countries. Results for the 1999-2003 period seem to be largely affected by the global crash that followed the Asian crisis.
