Exchange risk premia and firm characteristics

This paper examines the presence and the determinants of exchange risk premia in stock returns using firm level data from South Korea. We conduct empirical asset pricing tests based on cross-sectional data sorted by firm characteristics such as firm size, liquidity, foreign ownership, and industry. Using alternative model specifications and exchange rate measures, our results support the hypothesis of a significant unconditional exchange risk premium in the Korean stock market at firm and industry levels. More specifically, we find that the exchange risk premium is directly related to firm liquidity and inversely related to firm size and foreign ownership.     

A brighter future with lower transactions costs?

Recently, the OMX Nordic Exchange reduced the exchange fee for trading the OMXS 30 index futures with more than 22%. The reduction in exchange fees provides this study with a unique opportunity to investigate the effects of a change in fixed transaction costs on futures market liquidity, trading activity, volatility, futures pricing efficiency, and the futures exchange's revenues. The results show a ceteris paribus increase in futures trading volume with 19%, a 27% decrease in futures bid–ask spread, and a 27% increase in volatility, as a result of the futures exchange fee reduction, whereas the pricing efficiency of the futures contract and the exchange's revenues are unaffected by the change in transaction costs. The exchange fee reduction has improved futures market liquidity at the cost of higher volatility. Moreover, the attractiveness and competitiveness of the futures exchange has increased relative alternative trading venues, without a loss of revenues in the process. © 2009 Wiley Periodicals, Inc.

The anatomy of financial crises: Evidence from the emerging ADR market

We study the anatomy of recent financial crises in Mexico, East Asia, Russia, Brazil, Turkey, and Argentina by investigating the efficiency and pricing of the emerging American depositary receipt (ADR) market. We use a non-parametric technique to test for persistent regime shifts in two basic structural relationships for ADR returns in 20 emerging countries — identified via arbitrage and capital mobility considerations — that should always hold in efficient and integrated capital markets. We find that those “normal” market conditions were instead often violated in proximity of financial crises: The law of one price often weakened (by 54% on average) and domestic sources of risk became more important (often by more than 100%) for many emerging ADRs. We also find the likelihood of these regime shifts to be related to proxies for uncertainty among investors, exchange rate volatility, trade linkages, and liquidity (but not stock market trends, currency devaluations, capital flight, or capital controls).     

权证发行对标的股票价格风险影响的实证研究

研究权证发行对标的证券价格风险的影响,对研究资本市场的有效性及权证定价等方面具有重要的意义。目前我国已经发行的备兑权证,运用资本资产定价模型(CAPM)和GARCH-M模型,探讨权证的发行时正股的无风险报酬、系统性风险(Beta)和总风险(报酬率波动性)是否有显著影响。实证结果表明,无论是认购权证、认沽权证,还是蝶式权证的发行对正股的无风险报酬、系统性风险的影响基本上均不显著,但对半数以上发行权证的股票的总风险有显著影响。抑制权证市场的投机性,发挥其本身应发挥的价格发现功能、促进股票的流动性、降低股价波动性等的功能,就必须从风险相互对冲的角度,循序渐进地大力发展权证等衍生产品的规模,促进衍生品市场健康、有序地发展。

Derivatives pricing with liquidity risk

This paper develops a novel, general derivative pricing model which introduces a liquidity risk factor. The model variants we outline offer a sufficient degree of flexibility so as to enable the valuation of various types of derivative classes including futures, American options, and mortgage backed security options, whereas existing derivative models can only price liquidity risk in European derivatives. We validate the model with oil and gold futures data and compare it to a classical benchmark model void of any liquidity risk. We find that our model is significantly more accurate than the classical model for pricing both oil and gold contracts.     

基于资产价值链的股票定价模型实证研究

从股票价格的形成过程入手提出可交易价值的概念,指出名义股价、流动性和波动性是其可能的影响因素。接着运用面板数据分析法对我国股市的周交易数据进行实证,发现可交易价值对股票的定价行为具有解释能力,且在不同市场环境下的表现形式不同:上涨行情中投资者偏好低价格、高流动和高波动的股票组合,下跌行情中则相反;走势平稳的市场中名义股价因子影响力最强,而流动性因子和波动性因子则在急涨急跌背景下更具影响力。     

Market Quality around Macroeconomic News Announcements: Evidence from the US and Canadian Markets

We investigate changes in market quality in the US and Canada during macroeconomic news announcements. We measure market quality in terms of returns dependence, the cost of trading, and pricing errors. Using a sample of cross‐listed stocks and macroeconomic news from both countries, we document that market quality is generally higher in the US than in Canada. The pattern of intraday serial dependence in returns reveals that it takes investors about 5 min less to react to order imbalances in the US than in Canada. We further observe that, around announcement periods, transaction costs increase more in Canada than in the US, suggesting that the US market offers better liquidity. More information is also incorporated into the US market. These results support the view that the US is a prime target for cross‐listing, and are robust to different types of assets and time specifications.     

Empirical evidence on cross-listed stocks of Central and Eastern European companies

This paper empirically investigates cross-listing's implications for companies in the newly-established capital markets in Central and Eastern Europe. Central and Eastern European companies face small capitalisation of local markets, limited liquidity and poor effectiveness of legal systems, all of which can have detrimental effects on stock pricing. We find that companies which issue Depositary Receipts and enter foreign markets experience a permanent value enhancement of about 26% around the event. We also observe that foreign listing significantly improves home market liquidity, which suggests that cross-listing helps to draw the interest of new investors and encourages them to start trading in both foreign and local markets. Moreover, we find that the pricing efficiency increases after foreign listing, which is reflected in reduced stock return autocorrelation.     

Flight-to-liquidity: Evidence from China's stock market

In an order-driven and strictly regulated stock market, illiquidity risks' effects on asset pricing should be highlighted, particularly in such extreme market conditions as those in China. This paper utilizes panel data from China's stock market in an attempt to answer whether the illiquidity risk in various dimensions—including price impacts, the transaction speed, trading volume, transaction costs, and asymmetric information—can explain stock returns. We find that almost all dimensions of stock illiquidity are positively associated with excess stock returns. More importantly, smaller, less-liquid stocks suffer more liquidity costs, providing a strong evidence for “flight-to-liquidity.” Additionally, the transaction costs and asymmetric information, denoted by bid-ask spreads, robustly account for these illiquidity effects on stock pricing and differ from the findings in the U.S. market. We also find that the “flight-to-liquidity” can partially explain the idiosyncratic volatility puzzle, investors' gambling, and herding psychologies. This study provides substantial policy implications in regulation and portfolio management for emerging markets.     

Is there an illiquidity premium in frontier markets?

We perform a comprehensive examination of the role of stock-level liquidity in the cross-section of frontier market stock returns. Using several popular liquidity measures and a battery of asset pricing tests, we investigate the illiquidity premium in 22 countries for the years 1991–2019. Contrary to typical relationships in developed and emerging markets, we find no evidence of illiquidity premium in frontier equities. Our findings support the hypothesis that for countries not fully integrated with the global economy, the diversification benefits offset the illiquidity, which, in turn, proves less important.     

货币流动性和市场流动性:波动与风险

目前,货币流动性和市场流动性的关系成为股票市场参与者关注的焦点。本文分析了货币流动性与市场流动性的联系,实证研究了货币流动性和市场流动性的波动关系,以及货币流动性对市场流动性风险的影响,发现货币流动性M2、M1和市场非流动性动态负相关,M0与市场非流动性动态不相关;货币流动性M2和M1的正向冲击能一定程度降低市场流动性波动风险,而M0会增加市场流动性波动风险,市场流动性风险自身是影响市场后期流动性风险的最大因素。     

Liquidity shocks,commodity financialization,and market comovements

We explore whether and how liquidity factors influence risk transfers between commodity and stock markets using a composite liquidity index and five different types of liquidity measures. We find that liquidity shocks, including both funding liquidity and market liquidity, are positively associated with comovements between commodity and stock markets after 2000, although the relationship is insignificant before 2000. The structural change indicates that financialization creates a role for adverse liquidity shocks to increase cross-market correlations. Further evidence shows that the effect of liquidity on cross-market correlations is state-dependent and intensifies when liquidity conditions deteriorate and asset returns sustain substantial declines. Our findings are not explained by business cycles.     

The impact of a pro‐rata algorithm on liquidity: Evidence from the NYSE LIFFE

This study investigates the impact of introducing a pure pro‐rata algorithm on the liquidity of the market for Euribor futures contracts on NYSE LIFFE. Results indicate that the Euribor market experiences deterioration in liquidity: (1) both best and total depth fall and (2) quoted spreads widen after the structural change. Results also reveal that the Euribor market becomes more active after the event; both trading volume and trade frequency increase substantially after the event. Finally, after the transition, liquidity demanders are more likely to submit smaller market orders. The reduction in depth and increase in quoted spreads suggest that liquidity demanders incur higher trade execution costs after the transition. In contrast, the transition is beneficial for the exchange since trading volume is higher under the new regime. © 2011 Wiley Periodicals, Inc. Jrl Fut Mark 32:660–682, 2012     

Sharing contracts' marginalisation,adverse selection and markup calculation

This paper proposes a new approach to explain the dominance—in the Islamic banking market—of markup contracts at the expense of sharing ones. We show that the dual pricing practised in this market produces an additional—or artificial—dimension of adverse selection, which is causing the sharing contracts' marginalization. We suggest specialized use of two Islamic contractual categories as a device for eliminating artificial adverse selection. We suggest also an endogenous calculation of the markup, that is independent of the interest rate, based on the financing cost unification. This approach allows the deduction of default and liquidity risk premiums.     

Are Derivative Warrants Overpriced?

This study investigates the pricing efficiency of Hang Seng Index (HSI) derivative warrants in Hong Kong. Different from similar research, the study examines the pricing efficiency of index warrants by comparing their implied volatilities (IV) with realized volatility (RV). Although prior studies find that warrants are more expensive than the corresponding options, they are not necessarily overpriced in the conventional sense—that is, relative to the RV. This approach allows the study to test the pricing efficiency of warrants via a test of their information content. Moreover, unlike studies that focus on data at market close, the study uses a large sample of highly synchronous intraday, firm, bid–ask quote data to avoid possible distortions arising from intraday variations in liquidity and pricing in the instruments. The data also helps eliminate the potential nonsynchronous price problem that may affect the test results. Consistent with the results from previous studies, we find that warrants are often more expensive than options. This result is attributed to the inability of non‐issuers to sell short, and the high participation rate of unsophisticated investors in the warrants market. However, regression analysis shows that IVs from ATM and OTM warrants provide unbiased volatility forecasts, and that IVs from ATM options do not subsume the information content of ATM warrants. ATM warrant prices are in line with the RV and are efficiently priced. Simulation results show that writing warrants is more profitable than writing options, and that the overpricing is directly related to the volatility premium.     

Intraday Liquidity Provision by Trader Types in a Limit Order Market: Evidence from Taiwan Index Futures

This study examines the dynamic liquidity provision process by institutional and individual traders in the Taiwan index futures market, which is a pure limit order market. The empirical analysis obtains several interesting empirical results. We find that trader type affects liquidity provision in a number of interesting ways. First, although institutional traders use more limit orders than market orders, foreign institution (individual) traders use a relatively higher percentage of market (limit) orders in the early trading session and then switch to more limit (market) orders for the remainder of the day until close to the end of the trading day. Second, net limit order submissions by both institutional and individual traders are positively related to one‐period lagged transitory volatility and negatively related to informational volatility. Third, net limit order submissions by institutional traders are positively related to one‐period lagged spread. Finally, both the state of limit order book and order size significantly influence all types of traders’ strategy on submission of limit order versus market order during the intraday trading session. © 2012 Wiley Periodicals, Inc.

A generalized theoretical modelling approach for the assessment of economic-capital under asset market liquidity risk constraints

This paper proposes a concrete theoretical foundation and a new modelling framework that attempts to tackle the issue of market/liquidity risk and economic-capital estimation at a portfolio level by combining two mutual asset market/liquidity risk models. In essence, this study extends research literature related to the assessment of the asset market/liquidity risk by providing a generalized theoretical modelling underpinning that handle, from the same perspective, market and liquidity risks jointly and integrate both risks into a portfolio setting without a commensurate increase of statistical postulations. As such, we argue that market and liquidity risk components are correlated in most cases and can be integrated into one single market/liquidity framework that consists of two interrelated sub-components. The first component is attributed to the impact of adverse price movements and is modelled based on the concept of liquidity-adjusted value-at-risk framework, while the second component focuses on the risk of variation in transactions costs due to the bid-ask spreads and it attempts to measure the likelihood that it will cost more than expected to liquidate the asset position. As such, the model comprises a new approach to contemplating the impact of time-varying volatility of the bid-ask spread and its upshot on the overall asset market/liquidity risk. The modelling framework can be constructive for financial service industries in emerging-economies and particularly in reinforcing rational economic-capital allocation in light of the aftermaths of the sub-prime financial crisis.     

Stock liquidity and ownership structure during and after the 2008 Global Financial Crisis: Empirical evidence from an emerging market

This paper examines the impact of ownership structure, whether state owned, foreign owned or institutionally owned, on Vietnamese stock market liquidity in different market conditions. We find that state ownership is associated with lower liquidity after the 2008 financial crisis. Institutional ownership shows a weak influence on liquidity in the post-crisis period. During the financial crisis, however, liquidity declines could not be attributed to ownership structure. Our results imply that foreign investors have not yet played a significant role in driving stock market liquidity in Vietnam, which is counter to findings in the existing literature concerning liquidity in more developed markets. Our results are consistent across conventional liquidity measures and a composite liquidity measure.     

Enhancing market discipline in banking: The role of subordinated debt in financial regulatory reform

The increasing complexity of large financial firms has led to consideration of alternative regulatory structures. This has intensified recently because of the worldwide turmoil in financial markets. One important consideration has been to increase reliance on market discipline—most notably, increased reliance on subordinated debt (sub-debt) in the bank capital structure to discipline banks’ risk taking. This proposal, however, has been subject to criticism related to the quality of the signal generated in current sub-debt markets. We argue that previous studies evaluating the potential usefulness of sub-debt proposals have evaluated sub-debt spreads in a very different environment from that characterized by a fully implemented sub-debt program, where the market will become deeper, issuance will be more frequent, debt will be viewed as a more viable means to raise capital, bond dealers will be less reluctant to publicly disclose more details on debt transactions, and generally, the market will be more closely followed. As a test to see how the quality of the signal may change, we evaluate the risk-spread relationship—accounting for the enhanced liquidity and market transparency surrounding new debt issues. Our empirical results indicate a superior risk-spread relationship surrounding the period of new debt issuance due, we posit, to greater liquidity and transparency. Our results overall suggest that the degree of market discipline would be significantly enhanced by a mandatory sub-debt program, thus suggesting a potential role for sub-debt in the banking regulatory reform.
