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 …

Community Banking In The E-Business Era, Peter Southard, Keng Siau Jan 2002

Community Banking In The E-Business Era, Peter Southard, Keng Siau

Research Collection School Of Computing and Information Systems

This paper reviews how existing and potential uses of Internet technology can generate a competitive advantage for rural community banks. To do so, it offers a framework for analyzing Internet technology investment decisions. Organizations in this segment of the banking industry are often more removed from centers of technology and have traditionally been more conservative in their approaches to information technology (among other things). Banking Associations have developed in the U.S., such as the Independent Bankers Association, to try and help community banks coordinate marketing, legislative, and other issues that they have in common. The use of Internet technology can …

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 …

Forecasting Volatility: Evidence From The German Stock Market, Hagen H. W. Bluhm, Jun Yu Feb 2001

Forecasting Volatility: Evidence From The German Stock Market, Hagen H. W. Bluhm, Jun Yu

Research Collection School Of Economics

In this paper we compare two basic approaches to forecast volatility in the German stock market. The first approach uses various univariate time series techniques while the second approach makes use of volatility implied in option prices. The time series models include the historical mean model, the exponentially weighted moving average (EWMA) model, four ARCH-type models and a stochastic volatility (SV) model. Based on the utilization of volatility forecasts in option pricing and Value-at-Risk (VaR), various forecast horizons and forecast error measurements are used to assess the ability of volatility forecasts. We show that the mode lrankings are sensitive to …

Justifying Electronic Banking Network Expansion Using Real Option Pricing: An Empirical Illustration, Michel Benaroch, Robert J. Kauffman Jun 2000

Justifying Electronic Banking Network Expansion Using Real Option Pricing: An Empirical Illustration, Michel Benaroch, Robert J. Kauffman

Research Collection School Of Computing and Information Systems

The application of real options analysis to information technology investment evaluation problems recently has been proposed in the IS literature (Chalasani et al. 1997; Dos Santos 1991; Kambil et al. 1993; Kumar 1996; Taudes 1998). The research reported on in this paper illustrates the value of applying real options analysis in the context of a case study involving the deployment of point-of-sale (POS) debit services by the Yankee 24 shared electronic banking network of New England. In the course of so doing, the paper also attempts to operationalize real options analysis concepts by examining claimed strengths of this analysis approach …

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 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 …

Joint Variance Ratio Tests Of The Martingale Hypothesis For Exchange Rates, Wai Mun Fong, Benedict Seng Kee Koh, Sam Ouliaris Jan 1997

Joint Variance Ratio Tests Of The Martingale Hypothesis For Exchange Rates, Wai Mun Fong, Benedict Seng Kee Koh, Sam Ouliaris

Research Collection Lee Kong Chian School Of Business

There is considerable interest in whether exchange rates behave like martingales. Liu and He tested the martingale hypothesis for exchange rates using the variance-ratio methodology of Lo and MacKinlay. They found that exchange rates have violated the martingale property since the inception of floating rates in 1973. Liu and He did not consider the joint implications of their tests, however. In this article, we reassess the martingale hypothesis for exchange rates using the joint tests developed by Hochberg and by Richardson and Smith. Contrary to the findings of Liu and He, the joint tests indicate that the martingale model worked …

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 …

The Vehicle Quota System In Singapore: An Assessment, Winston T. H. Koh, David K. C. Lee Jan 1994

The Vehicle Quota System In Singapore: An Assessment, Winston T. H. Koh, David K. C. Lee

Research Collection Lee Kong Chian School Of Business

This paper reviews the developments since the vehicle quota system was introduced in Singapore in May 1990. We discuss the bidding strategies for the certificates of entitlement (COE) under both the transferable and nontransferable auctions, as well as the equity of the present system and the desirability of transferable COEs. We argue that the COE auction should be made discriminatory and propose an alternative system of COE auction that we feel is both equitable and at the same time politically acceptable. We also survey developments in market competition in the car industry.

Share-Price-Changes-Volume Relation On The Singapore Equity Market, David K. C. Lee, Mohamed Ariff Dec 1993

Share-Price-Changes-Volume Relation On The Singapore Equity Market, David K. C. Lee, Mohamed Ariff

Research Collection Lee Kong Chian School Of Business

A critical review of the literature on security-price-changes-volume research suggests that the published studies in the United States and one each in Hong Kong and Japan have largely ignored the impacts on the results from autocorrelation, non-normality of distributions, heteroscedasticity and non-linear functional forms. Therefore, the reported findings are not robust. In testing for this relation from a small sample of continuously traded shares in the Singapore share market, we find that consistent results may not be obtained because of violations of basic test conditions. A task that remains is an application of alternative test models with data transformation using …

Is A Bond Rating Downgrade Bad News, Good News, Or No News For Stockholders?, Choo Yong, Jeremy Goh, Louis H. Ederington Dec 1993

Is A Bond Rating Downgrade Bad News, Good News, Or No News For Stockholders?, Choo Yong, Jeremy Goh, Louis H. Ederington

Research Collection Lee Kong Chian School Of Business

We examine the reaction of common stock returns to bond rating changes. While recent studies find a significant negative stock response to downgrades, we argue that this reaction should not be expected for all downgrades because: (1) some rating changes are anticipated by market participants and (2) downgrades because of an anticipated move to transfer wealth from bondholders to stockholders should be good news for stockholders. We find that downgrades associated with deteriorating financial prospects convey new negative information to the capital market, but that downgrades due to changes in firms' leverage do not.

Auctions For Transferable Objects: Theory And Evidence From The Vehicle Quota System In Singapore, David K. C. Lee, Winston T. H. Koh Oct 1993

Auctions For Transferable Objects: Theory And Evidence From The Vehicle Quota System In Singapore, David K. C. Lee, Winston T. H. Koh

Research Collection Lee Kong Chian School Of Business

This paper studies the hypothesis that auctions with resale markets result in higher prices. The vehicle quota system introduced in Singapore in May 1990 provides the setting. The Certificates of Entitlement (COEs) necessary to purchase new cars were initially transferable for all quota categories. After October 1991, COEs for four major categories became non-transferable. Our results indicate that while the conversion to non-transferability eliminated speculation, it has also intensified competition among car distributors. Auctions for non-transferable COEs in fact led to higher COE prices in three of the four categories.

Event-Study Methodology Under Conditions Of Event-Induced Variance, Ekkehart Boehmer, Jim Masumeci, Annette B. Poulsen Dec 1991

Event-Study Methodology Under Conditions Of Event-Induced Variance, Ekkehart Boehmer, Jim Masumeci, Annette B. Poulsen

Research Collection Lee Kong Chian School Of Business

Many authors have identified the hazards of ignoring event-induced variance in event studies. To determine the practical extent of the problem, we simulate an event with stochastic effects. We find that when an event causes even minor increases in variance, the most commonly-used methods reject the null hypothesis of zero average abnormal return too frequently when it is true, although they are reasonably powerful when it is false. We demonstrate that a simple adjustment to the cross-sectional techniques produces appropriate rejection rates when the null is true and equally powerful tests when it is false.
