The Contribution Of A Satellite Market To Price Discovery: Evidence From The Singapore Exchange, Vicentiu Covrig, David K. Ding, Buen Sin Low Oct 2004

The Contribution Of A Satellite Market To Price Discovery: Evidence From The Singapore Exchange, Vicentiu Covrig, David K. Ding, Buen Sin Low

Research Collection Lee Kong Chian School Of Business

The Singapore Exchange (SGX), a small satellite market, successfully competes with a large home market, the Osaka Securities Exchange (OSE), in trading the Nikkei 225 futures index. In this paper, we investigate the contribution of the SGX to price discovery and shed light on the reasons for its continued success. Evidence is provided from information revelation and price discovery of three competing but informationally linked markets of the Nikkei 225 index - domestic spot (Tokyo Stock Exchange), domestic futures (OSE), and foreign futures (SGX), which represents the satellite market. Overall, the futures market contributes 77% to price discovery, with the …


Testing Market Efficiency Using Statistical Arbitrage With Applications To Momentum And Value Strategies, Steve Hogan, Robert Jarrow, Melvyn Teo, Mitchell Warachka Sep 2004

Testing Market Efficiency Using Statistical Arbitrage With Applications To Momentum And Value Strategies, Steve Hogan, Robert Jarrow, Melvyn Teo, Mitchell Warachka

Research Collection Lee Kong Chian School Of Business

This paper introduces the concept of statistical arbitrage, a long horizon trading opportunity that generates a riskless profit and is designed to exploit persistent anomalies. Statistical arbitrage circumvents the joint hypothesis dilemma of traditional market efficiency tests because its definition is independent of any equilibrium model and its existence is incompatible with market efficiency. We provide a methodology to test for statistical arbitrage and then empirically investigate whether momentum and value trading strategies constitute statistical arbitrage opportunities. Despite adjusting for transaction costs, the influence of small stocks, margin requirements, liquidity buffers for the marking-to-market of short-sales, and higher borrowing rates, …


Risk, Return And Risk Aversion: A Behavioral Rendition, Hian Ann, Christopher Ting Sep 2004

Risk, Return And Risk Aversion: A Behavioral Rendition, Hian Ann, Christopher Ting

Research Collection Lee Kong Chian School Of Business

Behavioral finance and classical finance based on utility maximization appear to be mutually exclusive schools of thought. Despite the fundamental difference, we show that behavioral finance also has a linear relation between risk and return. This relation is obtained without the assumptions of market equilibrium, rational expectations, a specific utility function and the market portfolio. In the behavioral approach, the pricing error of CAPM is not an error. It is attributable to the higher-order moments of return. Empirical tests suggest that the relative risk aversion coefficient is positive and time-varying. Moreover, it correlates negatively with both volatility and return.


Information Contents Of Trade And Quote Imbalances, And The Hypothesis Of Reverse Liquidity, Hian Ann, Christopher Ting Sep 2004

Information Contents Of Trade And Quote Imbalances, And The Hypothesis Of Reverse Liquidity, Hian Ann, Christopher Ting

Research Collection Lee Kong Chian School Of Business

In this paper, we study the information contents of imbalances in trades and quotes emanated from an exchange resembling the one envisioned by Black (1971). We find dollar volume is more informative than number in measuring daily trading and quoting activities. Our measure of quote imbalance permits an investigation on the information asymmetry between market and limit orders. In case illegal insider trading does not occur regularly, we present a hypothesis of reverse liquidity as an alternative interpretation for our empirical findings. It could be that market-order traders charge an implicit liquidity premium for fulfilling the contrarian trading demand of …


How Do Institutional Investors Trade, Paul G. J. O'Connell, Melvyn Teo Aug 2004

How Do Institutional Investors Trade, Paul G. J. O'Connell, Melvyn Teo

Research Collection Lee Kong Chian School Of Business

Using a novel and detailed custody trades dataset, this paper analyzes the trading behavior of institutions. Extant studies have examined the effects of past performance on trading by retail investors, day traders, and futures floor traders. Yet very little work has been done on institutions. We find that unlike other investors, institutions take on more risk following an increase in net profit and loss. However, the responses to a gain and loss are highly asymmetric. Institutions aggressively reduce risk in the wake of losses, but only mildly increase risk in the wake of gains. This asymmetry is more pronounced for …


International Cross-Listing And The Bonding Hypothesis, Dan Segal, Michael King May 2004

International Cross-Listing And The Bonding Hypothesis, Dan Segal, Michael King

Research Collection School Of Accountancy

The authors describe a new view of cross-listing that links the impact on firm valuation to the firm's ability to develop an active secondary market for its shares in the U.S. markets. Contrary to previous research, cross-listing may not provide benefits for all firms, even when those firms meet the highest regulatory requirements for disclosure and supervision. When cross-listed firms are divided into two groups on the basis of their share turnover in the home market relative to the U.S. market, the firms that develop active trading in the U.S. market experience an increase in valuation. Cross-listed firms that remain …


Equity Style Returns And Institutional Investor Flows, Kenneth A. Froot, Melvyn Teo Mar 2004

Equity Style Returns And Institutional Investor Flows, Kenneth A. Froot, Melvyn Teo

Research Collection Lee Kong Chian School Of Business

This paper explores institutional investor trades in stocks grouped by style and the relationship of these trades with equity market returns. It aggregates transactions drawn from a large universe of approximately $6 trillion of institutional funds. To analyze style behavior, we assign equities to deciles in each of five style dimensions: size, value/growth, cyclical/defensive, sector, and country. We find, first, strong evidence that investors organize and trade stocks across style-driven lines. This appears true for groupings both strongly and weakly related to fundamentals (e.g., industry orcountry groupings versus size or value/growth deciles). Second, the positive linkage between flows and returns …


Privatizing Telecoms And Residual State Influence On Financial Performance, Burkhard N. Schrage, Paul M. Vaaler Jan 2004

Privatizing Telecoms And Residual State Influence On Financial Performance, Burkhard N. Schrage, Paul M. Vaaler

Research Collection Lee Kong Chian School Of Business

We test competing theoretical perspectives explaining likely shareholder returns from material investment decisions announced by privatizing telecommunications firms (telecoms) with varying levels of residual state ownership. A principal-agent perspective suggests that decrease in residual state ownership in privatizing telecoms leads to more positive shareholder returns. Over time, this effect increases. An alternative credible privatization perspective suggests that retention of substantial (though not controlling) residual state ownership leads to more positive shareholder returns, but only in the short run. Over time this ownership effect fades quickly. We examine empirical support for these competing perspectives with an event study analyzing cumulative abnormal …


Prospect Theory And Institutional Investors, Melvyn Teo, Paul G. J. O'Connell Nov 2003

Prospect Theory And Institutional Investors, Melvyn Teo, Paul G. J. O'Connell

Research Collection Lee Kong Chian School Of Business

There is ample evidence that past performance affects the trading decisions of individual investors. This paper looks at this issue using a detailed database of currency trading decisions of institutional investors. Past performance manifestly affects currency risk-taking in this group, but the sign and magnitude of the effect runs counter to much of the existing theory and evidence. There is no evidence whatsoever of disposition effects; rather, the dominant characteristic is aggressive risk reduction in the wake of losses. This effect is more prominent later in the year, and among older and more experienced funds. A modified version of the …

Stock Exchange Governance And Market Quality, Chandrasekhar Krishnamurti, John M. Sequeira, Fangjian Fu Sep 2003

Stock Exchange Governance And Market Quality, Chandrasekhar Krishnamurti, John M. Sequeira, Fangjian Fu

Research Collection Lee Kong Chian School Of Business

We show that organization structure of a stock exchange matters by utilizing the unique setting prevailing in India. India has two major stock markets, the Bombay Stock Exchange (BSE) and the National Stock Exchange (NSE). These two exchanges adopt similar trading systems, trade essentially identical stocks, and follow the same trading hours. However, these exchanges have different organizational structures: BSE is mutualized whereas NSE is demutualized. Using the Hasbrouck [Review of Financial Studies 6 (1993) 191] measure of market quality we show that NSE provides a better quality market than BSE. This result is consistent with the work of Domowitz …


Trading Your Neighbor's Etfs: Competition Or Fragmentation?, Beatrice Boehmer, Ekkehart Boehmer Sep 2003

Trading Your Neighbor's Etfs: Competition Or Fragmentation?, Beatrice Boehmer, Ekkehart Boehmer

Research Collection Lee Kong Chian School Of Business

On July 31, 2001, for the first time in its history, the New York Stock Exchange (NYSE) began trading three unlisted securities. The DIA, SPY, and QQQ are the most actively traded Exchange Traded Funds (ETFs) and are listed on the American Stock Exchange. On April 15, 2002 another 27 ETFs followed. These two events provide a unique experiment for studying the impact of a new entrant on market quality. In contrast to recently revived concerns about the adverse impact of market fragmentation, we document that the NYSE entry leads to a dramatic improvement in liquidity that we attribute to …


Asymptotic Dynamics And Value-At-Risk Of Large Diversified Portfolios In A Jump-Diffusion Market, Kian Guan Lim, Xiaoqing Liu, Kai Chong Tsui Sep 2003

Asymptotic Dynamics And Value-At-Risk Of Large Diversified Portfolios In A Jump-Diffusion Market, Kian Guan Lim, Xiaoqing Liu, Kai Chong Tsui

Research Collection Lee Kong Chian School Of Business

This paper studies the modelling of large diversi ed portfolios in a nancial market with jump-di usion risks. The portfolios considered include three categories: equal money-weighted portfolios, risk minimizing portfolios, and market indices. Reduced-form dynamics driven jointly by one Brownian Motion and one Poisson process are derived for the asymptotics of such portfolios. We prove that derivatives written on a portfolio can be priced by treating the asymptotic dynamics as the underlying process if the number of assets in the portfolio is su ciently large. Analytical and Monte Carlo Value-at-Risk (VaR) can be computed for the portfolios based on their …


Estimating Credit Risk Premia, Kian Guan Lim Sep 2003

Estimating Credit Risk Premia, Kian Guan Lim

Research Collection Lee Kong Chian School Of Business

This paper investigates the nature of the credit risk premium adjustments in the Jarrow-Lando-Turnbull model of credit risk spreads. The adjustments relate the equivalent martingale measures to the empirical measures of unconditional transition probabilities. We provide a modi ed version of the risk adjustment that allows a linear partition of the credit spread into an unconditional default component, a recovery component, and the risk premium adjustment. The risk adjustments are related to conditional default risk, illiquidity risk, and other factors not related to recovery e ects. The log-transform of these risk adjustments can be speci ed as linear regressions on …


Spread, Depth, And Order Flow Patterns Of Warrants And Their Underlying Stocks On The Stock Exchange Of Thailand, Charlie Charoenwong, Nuttawat Visaltanachoti, David K. Ding Jul 2003

Spread, Depth, And Order Flow Patterns Of Warrants And Their Underlying Stocks On The Stock Exchange Of Thailand, Charlie Charoenwong, Nuttawat Visaltanachoti, David K. Ding

Research Collection Lee Kong Chian School Of Business

This study compared the trading characteristics of warrants and their underlying stocks. The Stock Exchange of Thailand provided a good platform for comparing the trading characteristics of warrants and their underlying stocks because both these securities are traded in the same market venue and have identical trading rules. Hence, the impact of trading protocol on intraday variation and an informed trader's decision to buy warrants or stocks was controlled. The paper found that they have a similar downward sloping pattern of spreads, adverse selection component, and liquidity immediacy, U-shaped for volatility and trading volume, and upward-sloping for depth and market …

Asian Hedge Funds: Return Persistence, Style, And Fund Characteristics, Francis Koh, Winston T. H. Koh, Melvyn Teo Jun 2003

Asian Hedge Funds: Return Persistence, Style, And Fund Characteristics, Francis Koh, Winston T. H. Koh, Melvyn Teo

Research Collection Lee Kong Chian School Of Business

This study explores the return persistence properties, styles, and fund characteristics of hedge funds that mainly invest in Asia. We examine, for the first time, a high resolution hedge fund dataset which includes monthly return information as well as detailed fund characteristics data. We find that the returns of Asian hedge funds persist most strongly at monthly horizons to quarterly horizons. This persistence weakens considerably when we lengthen the measurement period beyond a quarter, and does not appear to be due to the imputation of fees or to systematic risk as measured by a simple factor model. Further, we show …


Dividend Omissions And Intraindustry Information Transfers, Gary L. Caton, Jeremy Goh, Ninon Kohers Mar 2003

Dividend Omissions And Intraindustry Information Transfers, Gary L. Caton, Jeremy Goh, Ninon Kohers

Research Collection Lee Kong Chian School Of Business

We examine potential information transfers from companies that announce dividend omissions to their industry rivals. Specifically, we examine the abnormal stock returns and abnormal earnings forecast revisions of rivals after a company makes a dividend-omission announcement. Our results show negative and significant abnormal stock returns and negative and significant abnormal forecast revisions for rival companies in response to the announcement, and a significant and positive relation between the two. We conclude that a dividend-omission announcement transmits unfavorable information across the announcing company's industry that affects cash flow expectations and ultimately stock prices.


The Effect Of Taxes On The Pricing Of Defaultable Debt, Kian Guan Lim, Fenghua Song, Mitchell Craig Warachka Jan 2003

The Effect Of Taxes On The Pricing Of Defaultable Debt, Kian Guan Lim, Fenghua Song, Mitchell Craig Warachka

Research Collection Lee Kong Chian School Of Business

Empirical studies have documented the dependence of corporate credit spreads on default risk, equity premiums, and taxes. However, taxes have previously not been incorporated into reduced-form credit risk models. Therefore, we first extend the existing literature by considering a default intensity that depends on taxes as well as the default-free short rate and a market index. Consequently, we establish a theoretical basis to explain previous empirical findings regarding the significant impact of taxation on defaultable bond prices. Unlike previous models, tax implications for defaultable debt cannot be constructed from a sum of tax effects on zero coupon bonds. Our empirical …


Are All Rivals Affected Equally By Bond Rating Downgrades?, Gary L. Caton, Jeremy Goh Jan 2003

Are All Rivals Affected Equally By Bond Rating Downgrades?, Gary L. Caton, Jeremy Goh

Research Collection Lee Kong Chian School Of Business

We use revisions in analysts' earnings forecasts to examine how the bad news associated with a bond rating downgrade gets transferred from the downgraded company to its rivals. In general, we find that stock analysts revise their earnings expectations downward for rivals of companies with downgraded debt. However, the significance of the revision is limited to rivals of downgraded companies with non-investment grade debt only. For the rivals of companies with investment grade debt, we find no significant forecast revisions. We hypothesize that this differential impact is due to differing levels of market visibility. This is consistent with our finding …


Investing In Hedge Funds: Risks, Returns And Pitfalls, Francis Koh, Winston T. H. Koh, David Kuo Chuen Lee, Kok Fai Phoon May 2002

Investing In Hedge Funds: Risks, Returns And Pitfalls, Francis Koh, Winston T. H. Koh, David Kuo Chuen Lee, Kok Fai Phoon

Research Collection Lee Kong Chian School Of Business

Hedge funds are collective investment vehicles fast becoming popular with high net worth individuals as well as institutional investors. These are funds that are often established with a special legal status that allows their investment managers a free hand to use derivatives, short sell, and exploit leverage to raise returns and cushion risk. Given that that they have substantial latitude to invest, it is instructive to examine the performance of hedge funds compared to other forms of managed funds. This paper provides an overview of hedge funds and discusses their empirical risk and return profiles. It also poses some concerns …


Persistence In Style-Adjusted Mutual Fund Returns, Melvyn Teo, Sung-Jun Woo Nov 2001

Persistence In Style-Adjusted Mutual Fund Returns, Melvyn Teo, Sung-Jun Woo

Research Collection Lee Kong Chian School Of Business

The literature on mutual fund persistence took a hit with the finding that one-year stock momentum and expense ratios account for most of the persistence in mutual fund performance (Carhart, 1992; Carhart, 1997). However, since equity mutual funds are grouped into styles (e.g., large value, small growth, mid-cap growth, etc.) and are often confined to trading stocks within their style, one should measure fund performance relative to style when investigating managerial ability. Using CRSP mutual fund data and a methodology similar to Carhart (1997), we find that differences in style-adjusted fund returns persist for up to six years. Neither one-year …


The Effectiveness Of Institutional Activism, Gary L. Caton, Jeremy Goh, Jeffrey Donaldson Jul 2001

The Effectiveness Of Institutional Activism, Gary L. Caton, Jeremy Goh, Jeffrey Donaldson

Research Collection Lee Kong Chian School Of Business

Researchers examined earnings-forecast revisions and stock returns after release of the Focus List of poorly performing companies by the Council of Institutional Investors. Using Tobin's q as a measure of a company's ability to improve performance, researchers found significant and positive abnormal forecast revisions and post-release stock returns for companies with q greater than one. Findings support the proposition that institutional activism is effective for underperforming companies - but only those companies with the ability to respond to the challenge to improve performance.


Is A Convertible Bond Call Really Bad News?, Louis H. Ederington, Jeremy C. Goh Jul 2001

Is A Convertible Bond Call Really Bad News?, Louis H. Ederington, Jeremy C. Goh

Research Collection Lee Kong Chian School Of Business

The article tests and rejects the hypothesis that managers call in-the-money convertibles when they view a decline in the value of the firm as likely. Inconsistent with this view, it finds that insiders generally buy equity before conversion-forcing calls. Also, analysts tend to raise their earnings forecasts following a call. There is no evidence that earnings analysts interpret a conversion-forcing call as bad news. Indeed there is evidence that, relative to firms in general, analysts are revising their earnings forecasts upward in the months surrounding conversion-forcing calls. The article concludes that an announcement of a conversion-forcing call of a firm's …


An Investigation Of Price Discovery In Informationally-Linked Markets: Equity Trading In Malaysia And Singapore, David K. Ding, Frederick H. Harris, Sie Ting Lau, Thomas H. Mclnish Nov 1999

An Investigation Of Price Discovery In Informationally-Linked Markets: Equity Trading In Malaysia And Singapore, David K. Ding, Frederick H. Harris, Sie Ting Lau, Thomas H. Mclnish

Research Collection Lee Kong Chian School Of Business

Using transactions data for the Kuala Lumpur Stock Exchange and the Stock Exchange of Singapore (SES) for a major Malaysian conglomerate, Sime Darby Berhad, and intraday exchange rate data, we investigate whether and to what extent each exchange contributes to price discovery. Results indicate that the price series are cointegrated. The raw data appear to indicate the presence of arbitrage opportunities, but none exist after taking exchange rate changes into account. Using the common long-memory factors of Gonzalo and Granger (1995, Journal of Business and Economic Statistics 13, 1-9), we show that while the majority of the price discovery (approximately …


Private Placement Of Common Equity And Earnings Expectations, Jeremy C. Goh, Michael Gombola, Hai Wei Lee, Feng Ying Liu Aug 1999

Private Placement Of Common Equity And Earnings Expectations, Jeremy C. Goh, Michael Gombola, Hai Wei Lee, Feng Ying Liu

Research Collection Lee Kong Chian School Of Business

Earnings forecast revisions by analysts subsequent to the announcement of private equity placements are examined. Results show that analysts make significant upward revisions to their forecasts for current-year earnings. Furthermore, these forecast revisions are significantly related to announcement-period abnormal returns, but not to the risk changes accompanying the equity placement. These findings are consistent with the information hypothesis, which suggests that private equity placements convey favorable information about future earnings.


The Determinants Of Bid-Ask Spreads In The Foreign Exchange Futures Markets: A Microstructure Analysis, David K. Ding May 1999

The Determinants Of Bid-Ask Spreads In The Foreign Exchange Futures Markets: A Microstructure Analysis, David K. Ding

Research Collection Lee Kong Chian School Of Business

This paper investigates and analyzes the intraday and daily determinants of bid-ask spreads in the foreign exchange futures market. It is found that the number of transactions is negatively related to the BAS, whereas volatility in general is positively related to it. The study also finds that there are economies of scale in trading FXF contracts. The intraday BAS follows a U-shaped pattern, and they tend to be higher on Mondays and Tuesdays than on other days of the week. Higher spreads at the beginning and end of a trading day are consistent with the presence of adverse selection and …


Cross Sectional Variation Of The Effect Of Bond Rating Changes On Stock Prices, Jeremy C. Goh, Louis H. Ederington Jan 1999

Cross Sectional Variation Of The Effect Of Bond Rating Changes On Stock Prices, Jeremy C. Goh, Louis H. Ederington

Research Collection Lee Kong Chian School Of Business

Previous research has found that the stock market reacts negatively to bond rating downgrades and that downgrades tend to follow periods of negative returns, indicating that at least some downgrades are partially predictable. Hypothesizing that the reaction to a downgrade depends on both the implications for cash flows and the degree of surprise, we explore how the reaction to downgrade announcements varies across bond issues. We find that the equity market reacts much more negatively to bond rating downgrades to and within the speculative bond category than to downgrades within the investment grade category. Within the speculative category, the reaction …


Searching For Periods Of Volatility: A Study Of The Behavior Of Volatility In Thai Stocks, Theodore Bos, David K. Ding, Thomas A. Fetherston Aug 1998

Searching For Periods Of Volatility: A Study Of The Behavior Of Volatility In Thai Stocks, Theodore Bos, David K. Ding, Thomas A. Fetherston

Research Collection Lee Kong Chian School Of Business

This paper improves the precision of the useful new procedure of Inclán and Tiao (1994) that estimates variance shift points in a time series. It accomplishes this by incorporating the evidence of Bos and Fetherston (1992) that the linear Brown, Durbin, and Evans (Brown et al., 1975) critical CUSUM of squares boundaries [used by Inclán and Tiao] produce an understatement of instability at the data end points. This is solved by Tanizaki (1995) which, like Bos and Fetherston (1992) and Bos and Fetherston (1995), uses the fact that the CUSUM of squares statistic follows a beta distribution. This study uses …


The Information Content Of Fdi Announcements: Evidence From An Emerging Market, David K. Ding, Qian Sun Jan 1997

The Information Content Of Fdi Announcements: Evidence From An Emerging Market, David K. Ding, Qian Sun

Research Collection Lee Kong Chian School Of Business

This study examines the stock return responses to the announcements of foreign direct investments (FDI) by Singaporean companies. A standard event study methodology is used to ascertain the abnormal returns around the announcement day (day 0). The study covers the period from 1989 to 1994 with a sample size of 70 events. The announcement effect is positive and significant around the announcement day. The average abnormal return is 0.4913 percent on day 0, and the two-day (days 0 and 1) cumulative abnormal return is 0.9642 percent. However, the abnormal return is unequally distributed across the sample firms. A cross-sectional analysis …
