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 …

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 …

Does Underwriter Reputation Affect The Performance Of Ipo Stocks?, Chunchi Wu, Sheen Liu, Junbo Wang Sep 2003

Does Underwriter Reputation Affect The Performance Of Ipo Stocks?, Chunchi Wu, Sheen Liu, Junbo Wang

Research Collection Lee Kong Chian School Of Business

In this paper we examine the relationship between performance of the Chinese IPO firms and the reputation of investment bankers underwriting their stocks. Similar to previous studies on well-developed stock markets, we find that the initial return on the first day of trading is strongly positive for Chinese IPO stocks due to underpricing. This initial return is negatively related to the underwriter's reputation, suggesting that the better the reputation of the underwriter, the less underpricing and hence, the lower the initial return of the IPO stock. Extending the analysis to a ten-day window after the first trading day, we find …

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 …

Operationalizing Technology Improvements In Product Development Decision-Making, Shantanu Bhattacharya, V. Krishnan, Vijay Mahajan Aug 2003

Operationalizing Technology Improvements In Product Development Decision-Making, Shantanu Bhattacharya, V. Krishnan, Vijay Mahajan

Research Collection Lee Kong Chian School Of Business

Achieving competitive advantage and price premiums in many technology-based markets requires the incorporation of current technology in new products. To do so, firms in hyper-competitive environments increasingly plan and design their products concurrent with the independent development and validation of underlying technologies. Simultaneous validation of a core technology has important implications for a company's product positioning and launch sequence decisions making these traditional marketing decisions relevant to operations managers. Prior research has shown that to minimize cannibalization in the absence of such improvements in technology, a firm should not launch low-end products before high-end products. However, concurrent evolution of technology …

Maturity Effect On Bid-Ask Spreads Of Otc Currency Options, Beng Soon Chong, David K. Ding, Kok Hui Tan Jul 2003

Maturity Effect On Bid-Ask Spreads Of Otc Currency Options, Beng Soon Chong, David K. Ding, Kok Hui Tan

Research Collection Lee Kong Chian School Of Business

The paper ascertains the relation between bid-ask spreads and the contract maturity of OTC currency options. Contrary to previous findings in the futures market, spreads of currency options are found to be negatively related to the contract's term-to-maturity. The negative relation persists even after controlling for the effects of price risks, competition, and trading activity. The pronounced differences in the term-to-maturity results are attributable to the market risk effect and differences in the market structure of options and futures markets.

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.

Stimulating Firm-Specific Investment Through Risk Management, Heli Wang, Jay B. Barney, Jeffrey J. Reuer Feb 2003

Stimulating Firm-Specific Investment Through Risk Management, Heli Wang, Jay B. Barney, Jeffrey J. Reuer

Research Collection Lee Kong Chian School Of Business

This article suggests a rationale for firm risk management that has been largely ignored in financial economics literature. It presents an argument for harnessing the influence of a company’s stakeholders who, whether as employees, suppliers or customers, make a valuable investment specific to the company. Such investments are crucial for a firm’s competitive advantage, yet because they are firm-specific and therefore cannot be transformed or transferred, stakeholders are often concerned about the risks involved in making them. A company’s efforts to manage risk can therefore persuade stakeholders to make even greater firm-specific investments, bringing benefits to shareholders and stakeholders alike.

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 …

Venture Capital And Economic Growth: An Industry Overview And Singapore's Experience, Francis Koh, Winston T. H. Koh Nov 2002

Venture Capital And Economic Growth: An Industry Overview And Singapore's Experience, Francis Koh, Winston T. H. Koh

Research Collection Lee Kong Chian School Of Business

This paper provides an overview of the venture capital industry, and its development in Asia and Singapore. Venture capital plays an important role in innovation and economic growth. Indeed, the resurgence of the United States as a technology leader is intimately linked to the success of Silicon Valley. As Singapore enters the next phase of economic development, the creation of internal engines of growth is an urgent task. The Singapore government has done much to provide an environment for entrepreneurship to thrive. Its success at replicating the Silicon Valley culture will be important for Singapore's future economic success.

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 …

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 …

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.

Exploring Persistence In Financial Time Series, David K C. Lee Jan 2000

Exploring Persistence In Financial Time Series, David K C. Lee

Research Collection Lee Kong Chian School Of Business

If financial time series exhibits persistence or long-memory, then their unconditional probability distribution may not be normal. This has important implications for many areas in finance, especially asset pricing, option pricing, portfolio allocation and risk management. Furthermore, if the random walk does not apply, a wide range of results obtained by quantitative analysis may be inappropriate. The capital asset pricing model, the Black-Scholes option pricing formula, the concept of risk as standard deviation or volatility, and the use of Sharpe, Treynor, and other performance measures are not consistent with nonnormal distributions. Unfortunately, nonnormality is common among distributions of financial time …

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 …

Is The Term Premium A Risk Premium?, Louis H. Ederington, Jeremy C. Goh Sep 1999

Is The Term Premium A Risk Premium?, Louis H. Ederington, Jeremy C. Goh

Research Collection Lee Kong Chian School Of Business

This paper explores whether excess holding period returns on long vis-a-vis short-term securities behave in a manner that is consistent with (1) market efficiency, (2) the time-varying-term-premium variant of the expectations hypothesis, and (3) theories of the term premium that view it as a reward for risk bearing. Both traditional and modern theories of the term premium imply that it should evolve fairly slowly over time as attitudes toward risk and/or perceived covariances with wealth or consumption change. This implies that this period's term premium should have some predictive ability for next period's. However, we find that this quarter's ex-post …

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 …

Long Memory And Asia Crisis: Implication For Capital Controls And Management, Kuo Chuen David Lee Jan 1999

Long Memory And Asia Crisis: Implication For Capital Controls And Management, Kuo Chuen David Lee

Research Collection Lee Kong Chian School Of Business

“Financial markets are given to excesses and if a boom/bust sequence progresses beyond a certain point, it will never revert to where it came from. Instead of acting like a pendulum, financial markets have recently acted more like a wrecking ball, knocking over one economy after another.” - A testimony before the US House Banking Committee, Sep, 1998. There are three parts to this paper. The first part examines the time series behaviour of the equity indices of ten countries. Using Robinson (1995a)’s modified GPH estimator and Robinson (1994a)’s average periodogram estimator for the differencing parameter, we have detected that …

Bond Rating Agencies And Stock Analysts: Who Knows What When?, Louis H. Ederington, Jeremy C. Goh Dec 1998

Bond Rating Agencies And Stock Analysts: Who Knows What When?, Louis H. Ederington, Jeremy C. Goh

Research Collection Lee Kong Chian School Of Business

Both bond ratings agencies and stock analysts evaluate publicly traded companies and communicate their opinions to investors. Comparing the timelines of each, it is found that Granger causality flows both ways. While most bond downgrades are preceded by declines in actual and forecasting earnings, both actual earnings and forecasts of future earnings tend to fall following downgrades. Although part of this post-downgrade forecast revision can be attributed to negative news regarding actual earnings, most appears to be reaction to the downgrade itself. Little change is found in actual earnings following upgrades. Analysts, however, tend to increase their forecasts of future …

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 …

Breaking Trends And The Money-Output Correlation, David Fernandez Nov 1997

Breaking Trends And The Money-Output Correlation, David Fernandez

Research Collection Lee Kong Chian School Of Business

This paper examines the impact on the money-output correlation of a univariate specification that allows time series to be characterized as stationary around a broken trend function. Though pretesting suggests that U.S. real output (industrial production) can be described as broken-trend stationary, this result has only limited impact on the money-output correlation. Before 1985 there is a strong Granger causal relationship between money and broken-detrended output (hut not first-differenced output), even when different short-term interest rates are used as regressors. However, after 1985 this relationship weakens significantly, whether or not one determines that output has a unit root.

A Variance Decomposition Analysis Of The Information In The Term Structure, Louis H. Ederington, Jeremy C. Goh Mar 1997

A Variance Decomposition Analysis Of The Information In The Term Structure, Louis H. Ederington, Jeremy C. Goh

Research Collection Lee Kong Chian School Of Business

Based on a market efficiency assumption, we use variance decomposition analysis is to separate information in the term structure on expected future spot rates from information on time-varying term premia and to examine the market's ability to forecast both future rate changes and excess returns on long versus short securities. We find that fluctuations in the slope of the yield curve are due more to changing term premia than to fluctuations in expected future spot rates and that the market correctly predicts about 40 percent of the month-to-month changes in spot rates, a considerably higher percentage than that found by …

The Opening Price Behavior: Foreign Exchange Futures Market Versus Equity Market, Quentin C. Chu, David K. Ding, C. S. Pyun Jan 1997

The Opening Price Behavior: Foreign Exchange Futures Market Versus Equity Market, Quentin C. Chu, David K. Ding, C. S. Pyun

Research Collection Lee Kong Chian School Of Business

Daily opening, noon, and closing prices of Deutschemark and Japanese yen futures are examined for the efficiency of the foreign exchange futures (FXF) market. Variance ratio and multiple variance ratio tests, are employed. The prices are found to be serially uncorrelated. This random walk behavior sheds light on the differences between the FXF and commodity or equity markets. The conclusions suggest that the FXF market is a 24-hour global market, reflecting a disparity with equity markets where round-the-clock trading is advocated since the high volatility during market opening would be eliminated, leading to potential cost reductions for traders as spreads …
