Public Disclosure And Private Decisions: The Case Of Equity Market Execution Quality, Ekkehart Boehmer, Robert Jennings, Li Wei Mar 2007

Public Disclosure And Private Decisions: The Case Of Equity Market Execution Quality, Ekkehart Boehmer, Robert Jennings, Li Wei

Research Collection Lee Kong Chian School Of Business

In 2001, the Securities and Exchange Commission (SEC) required market centers to publish monthly execution-quality reports in an effort to spur competition for order flow between markets. Using samples of stocks trading on several markets, we investigate whether past execution quality affects order-routing decisions and whether the new disclosure requirements influence this relationship. We find that routing decisions are associated with execution quality; markets reporting low execution costs and fast fills subsequently receive more orders. Moreover, the reports themselves appear to provide information that was unavailable previously. Our results are consistent with active competition for order flow that can be …

Investing In Hedge Funds When Returns Are Predictable, Doron Avramov, Robert Kosowski, Narayan Y. Naik, Melvyn Teo Feb 2007

Investing In Hedge Funds When Returns Are Predictable, Doron Avramov, Robert Kosowski, Narayan Y. Naik, Melvyn Teo

Research Collection BNP Paribas Hedge Fund Centre

This paper evaluates hedge fund performance through portfolio strategies that incorporate predictability in managerial skills, fund risk loadings, and benchmark returns. Incorporating predictability substantially improves performance for the entire universe of hedge funds as well as for various investment styles. The outperformance is strongest during market downturns when the marginal utility of consumption is relatively high. Moreover, the major source of investment profitability is predictability in managerial skills. In particular, long-only strategies that incorporate predictability in managerial skills outperform their Fung and Hsieh (2004) benchmarks by over 17 percent per year. The economic value of predictability obtains for different rebalancing …

Foreign Funds Spy Hidden Bounties In Indian Distressed Assets, Knowledge@Smu Feb 2007

Foreign Funds Spy Hidden Bounties In Indian Distressed Assets, Knowledge@Smu

Knowledge@SMU

Foreign funds are garnering a sizable presence in India's nascent market for distressed assets, which is currently estimated between $45 billion and $55 billion. India's economic boom offers pockets of opportunity for investors to buy underperforming assets such as cement and sugar plants, revive them with fresh capital or liquidate them to profit handsomely. A big driver for this growing market is the government's move to purge the financial system of sick assets accumulated over decades, but obstacles include the absence of a developed corporate debt market, limits on foreign investments and procedural bottlenecks. India Knowledge@Wharton spoke to key participants …

Why Hedge Funds Are Looking To India For Greater Upside Potential, Knowledge@Smu Feb 2007

Why Hedge Funds Are Looking To India For Greater Upside Potential, Knowledge@Smu

Knowledge@SMU

A few years ago, hedge funds were barely on the radar screen in the Indian marketplace, and they were highly secretive investment vehicles even in the U.S. Today, it's a different story. As big returns are no longer easy to come by in domestic markets, international hedge funds are increasingly looking to countries like India and evaluating investment opportunities and the potential gains to be made. To understand what factors affect their success, India Knowledge@Wharton talked to experts from Wharton and elsewhere about the attractiveness -- as well as the risks -- of the Indian marketplace for hedge funds.

On Stiffness In Affine Asset Pricing Models, Shirley Junying Huang, Jun Yu Feb 2007

On Stiffness In Affine Asset Pricing Models, Shirley Junying Huang, Jun Yu

Research Collection Lee Kong Chian School Of Business

Economic and econometric analysis of continuous-time affine asset pricing models often necessitates solving systems of ordinary differential equations (ODEs) numerically. Explicit RungeûKutta (ERK) methods have been suggested to solve these ODEs both in the theoretical finance literature and in the financial econometrics literature. In this paper we show that under many empirically relevant circumstances the ODEs involve stiffness, a phenomenon which leads to some practical difficulties for numerical methods with a finite region of absolute stability, including the whole class of ERK methods. The difficulties are highlighted in the present paper in the context of pricing zero-coupon bonds as well …

A Cardan’S Discriminant Approach To Predicting Currency Crashes, Benedict Seng Kee Koh, Wai Mun Fong, Fabrice Chan Feb 2007

A Cardan’S Discriminant Approach To Predicting Currency Crashes, Benedict Seng Kee Koh, Wai Mun Fong, Fabrice Chan

Research Collection Lee Kong Chian School Of Business

This paper models large swings in exchange rates by introducing nonlinearity via the generalized normal (GEN) distribution [Lye, J.N., Martin, V.L., 1993. Robust estimation, nonnormalities and generalized exponential distributions. Journal of the American Statistical Association 88, 261-267]. As the distribution allows for bimodality, a switch between modes may give rise to currency crashes. A statistic known as Cardan's discriminant, based on the shape parameters of the GEN, is used to detect bimodality. The Cardan's discriminant is found to reliably predict currency crashes for eight emerging countries and generate relatively low false signals for stable currencies.

Why Global Banks Are Banking On India, Knowledge@Smu Jan 2007

Why Global Banks Are Banking On India, Knowledge@Smu

Knowledge@SMU

Foreign banks are aggressively expanding in India, both organically and through acquisitions. After playing along the sidelines in the country for more than 100 years, they have galvanized themselves to secure their share -- and more -- of the new action in the rapidly growing economy and a boom in high-profit consumer lending. India's central bank has outlined the roadmap for foreign players to grow, while the banking industry's robust fundamentals and crisis-free track record are other draws. To be sure, the entrenched public sector banks don't relish the charge of foreign banks. But the real rivals on the competing …

Synthetic Collateral Debt Obligation Pricing, Zhanyong Liu Jan 2007

Synthetic Collateral Debt Obligation Pricing, Zhanyong Liu

Dissertations and Theses Collection (Open Access)

Portfolio credit products, such as CDO and Single Tranche CDO (STCDO) have gained their popularity in financial industry. The key problem facing by the financial engineers is how to price these portfolio credit derivatives, especially how to model the dependent default structure. Copula model proposed by Li (2000) is widely used in practice. Comparing with simulation, factor copula model and conditional independent framework provide good balance between accuracy and computational efficiency, but it is hard to achieve good performance if sticking to normal distribution. There are a few ways to improve it: introducing Levy distributions, using generic copula functions, and …

Do Warrants Lead The Underlying Stocks And Index Futures?, Ying Kui Lin Jan 2007

Do Warrants Lead The Underlying Stocks And Index Futures?, Ying Kui Lin

Dissertations and Theses Collection (Open Access)

The lead-lag relation between options and stocks has been a subject of controversy for years with conflicting findings in the literature. In this thesis, we present an intuitive method to examine the lead-lag relation, if any, in the tick-by-tick data of covered warrants and their underlying stocks or underlying index futures. Our method is non-parametric and needs no assumptions which are critical to the regression-based methods. We find that the electronically traded warrants do not lead stocks or index futures; the movements in the warrants' quotes provide little information about the quotes of the underlying stocks or index futures. Instead, …

Interest Rate Uncertainty And Stock Market Volatility, Jincai Xu Jan 2007

Interest Rate Uncertainty And Stock Market Volatility, Jincai Xu

Dissertations and Theses Collection (Open Access)

The reason for volatility changing over time is still open. As stated in the extant papers uncertainty of Macroeconomic variable plays more important role in explaining the time varying of volatility than the volatility of Macroeconomic variable itself. In this paper we illustrate this with exploring the relationship between stock market volatility and the Interest Uncertainty. In the paper, we take the uncertainty of the decision of FOMC meeting as the uncertainty of interest rate. As we know, asset price is a tool for people to express their belief about the state of the economy, when uncertainty is high, a …

On The Calibration Of The Libor Market Model, U Lagunzad Demelinda Jan 2007

On The Calibration Of The Libor Market Model, U Lagunzad Demelinda

Dissertations and Theses Collection (Open Access)

This thesis presents a study of LIBOR market model calibration. In particular, the study builds on the prevailing calibration methodologies in an attempt to find a method that simultaneously recovers implied volatility and forward rate correlations structures from market prices of plain vanilla options. In order to ensure that complex derivative pricing and hedging requirements are jointly addressed, the study extends the performance analysis of calibration methods from a static level of goodness-of-fit with market prices test, to a dynamic level of approximation to next period's LIBOR (London Interbank Offer Rate) dynamics when tested on a series of market prices. …

Realized Daily Variance Of S&P 500 Cash Index: A Revaluation Of Stylized Facts, Shirley Huang, Qianqiu Liu, Jun Yu Jan 2007

Realized Daily Variance Of S&P 500 Cash Index: A Revaluation Of Stylized Facts, Shirley Huang, Qianqiu Liu, Jun Yu

Research Collection School Of Economics

In this paper the realized daily variance is obtained from intraday transaction prices of the S&P 500 cash index over the period from January 1993 to December 2004. When constructing realized daily variance, market microstructure noise is taken into account using a technique proposed by Zhang, Mykland and Ait-Sahalia (2005). The time series properties of realized daily variance are compared with those of variance estimates obtained from parametric GARCH and stochastic volatility models. Unconditional and dynamic properties concerning the realized daily variance are examined, the relationship between realized variance and returns is investigated, and the stylized facts concerning realized daily …

Modeling Transaction Data Of Trade Direction And Estimation Of Probability Of Informed Trading, Anthony S. Tay, Christopher Ting, Yiu Kuen Tse, Mitch Warachka Jan 2007

Modeling Transaction Data Of Trade Direction And Estimation Of Probability Of Informed Trading, Anthony S. Tay, Christopher Ting, Yiu Kuen Tse, Mitch Warachka

Research Collection School Of Economics

This paper implements the Asymmetric AutoregressiveConditional Duration (AACD) model of Bauwens and Giot (2003) to analyzeirregularly spaced transaction data of trade direction, namely buy versus sellorders. We examine the influence of lagged transaction duration, lagged volumeand lagged trade direction on transaction duration and direction. Our resultsare applied to estimate the probability of informed trading (PIN) based on theEasley, Hvidkjaer and O’Hara (2002) framework. Unlike the Easley-Hvidkjaer-O’Hara model, which uses the daily aggregate number of buy and sellorders, the AACD model makes full use of transaction data and allows forinteractions between buy and sell orders.

Risky Debt-Maturity Choice Under Information Asymmetry, Chunchi Wu, Sheen Liu Jan 2007

Risky Debt-Maturity Choice Under Information Asymmetry, Chunchi Wu, Sheen Liu

Research Collection Lee Kong Chian School Of Business

The traditional equilibrium models of signaling with debt-maturity require transaction costs by firms when raising new capital. In this paper, we propose a new model that has no such requirement. We demonstrate that a separating equilibrium of debt-maturity choice exists under a much more general condition, once accounting for the interactions between borrowers and lenders. The model is able to explain the observed complex financial structure. It is found that callable debt functions much like short-term debt, and serial debt similar to long-term debt. In equilibrium, high-quality firms issue short-term debt, and low-quality firms issue long-term debt.

What's Ahead For 2007? Knowledge@Wharton Network Surveys The Globe, Knowledge@Smu

Knowledge@SMU

On the financial front, 2006 has been a pretty good year all around. Stock markets in many countries have rallied, energy prices have fallen, inflation is relatively low and growth in GDP ranges from respectable to robust. But the economies of most countries also face a number of threats -- some predictable, some not -- that could derail recent gains in our increasingly connected global markets. What's ahead for 2007 in the U.S., India, Europe, Latin America, China and other parts of the world? We offer a roundup of reports from the Knowledge@Wharton Network, including India Knowledge@Wharton, Universia Knowledge@Wharton and …

The Association Between Earnings Quality And Regulatory Report Opinions In The Accounting Industry, Tracey Chunqi Zhang, Katherine Gunny Dec 2006

The Association Between Earnings Quality And Regulatory Report Opinions In The Accounting Industry, Tracey Chunqi Zhang, Katherine Gunny

Research Collection School Of Accountancy

We compare the outcome of two different information systems – self regulation versus private sector regulation – in the accounting industry. Under the Sarbanes-Oxley Act, Public Company Accounting Oversight Board (PCAOB) inspections replaced American Institute of Certified Public Accountants (AICPA) peer reviews of auditors. Peer review opinions are useful with respect to decisions about hiring and firing of auditors (Hilary and Lennox, 2005); therefore, the question remains what are the benefits of incurring the cost to replace a selfregulatory system with a private regulatory agency. We examine the usefulness of these two information systems at distinguishing earnings quality at firms …

The Effect Of The Options Backdating Scandal On The Stock-Price Performance Of 110 Accused Companies, Gennaro Bernile, Gregg A. Jarrell, Howard Mulcahey Dec 2006

The Effect Of The Options Backdating Scandal On The Stock-Price Performance Of 110 Accused Companies, Gennaro Bernile, Gregg A. Jarrell, Howard Mulcahey

Research Collection Lee Kong Chian School Of Business

Since academic scholars and the Wall Street Journal reported widespread evidence indicating that option grants to executives were backdated, an avalanche of news stories followed documenting this ever-widening corporate scandal. In this study we ask: "How do disclosures of backdating affect shareholder value?" We closely examine 110 companies listed in the Wall Street Journal's Perfect Payday webpage, collecting all news stories related to options backdating. We find that shareholders of these 110 companies suffer on average significant stock-price declines, ranging between 20% and 50%. Moreover, these losses do not seem to be due to temporary overreactions (at least so far). …

Choice Of Currency By East Asia Bond Issuers, David Fernandez, Simon Klassen Nov 2006

Choice Of Currency By East Asia Bond Issuers, David Fernandez, Simon Klassen

Research Collection Lee Kong Chian School Of Business

In discussing bond markets in Asia, academics and policymakers typically begin by noting that the Asian crisis of 1997-98 in part resulted from the underdevelopment of the region’s domestic bond markets and the resultant currency and duration mismatches. When assessing the progress made in developing these markets in the post-crisis years, academics and policymakers usually observe that, while several domestic currency government bond markets have moved ahead, corporate bond markets have lagged (Asian Development Bank (2002), Reserve Bank of Australia (2003)). The policy conclusion is therefore often drawn: to prevent another Asian crisis, Asian bond markets must be further developed.

Which Daily Price Is Less Noisy?, Christopher Ting Sep 2006

Which Daily Price Is Less Noisy?, Christopher Ting

Research Collection Lee Kong Chian School Of Business

The daily efficient price is the price that would prevail if the market were frictionless. I show that volume-weighted average price (VWAP) provides a less noisy estimate for the unobservable efficient price as compared to the closing price. The variance of daily returns computed with VWAPs is smaller than that computed with closing prices. The difference between these two realized variances is economically significant. The volatility of log closing price change tends to understate the beta risk and Sharpe ratio. A higher noise level in the closing price leads to derivative prices that favor option and volatility-related swap writers.

Is Stock Price Rounded For Economic Reasons In The Chinese Market, Yan He, Chunchi Wu Sep 2006

Is Stock Price Rounded For Economic Reasons In The Chinese Market, Yan He, Chunchi Wu

Research Collection Lee Kong Chian School Of Business

This paper investigates whether trading and quoting prices are rounded for both economic and cultural reasons on the Shanghai and Shenzhen Stock Exchanges in China. We find that the close, bid, and ask prices of domestic shares are rounded to the nearest 10s and 5s for economic reasons, and the last decimal point of prices clusters on 8 for cultural reasons. The cross-sectional variation in 10-cent and 5-cent rounding can be well explained by price and inverse of square root of trading volume, whereas the clustering on 8 can hardly be ascribed to economic variables. The cross-sectional variation in execution …

Asian Market Microstructure, David K. Ding, Charlie Charoenwong Jun 2006

Asian Market Microstructure, David K. Ding, Charlie Charoenwong

Research Collection Lee Kong Chian School Of Business

Along with the rapidly burgeoning Asian economy, the financial markets in the region have seen spectacular development during the past few decades. Several recent statistics will best illustrate their success. Net capital flows to Asia and Pacific over 1999 to 2003 constituted 40% of total flows to emerging markets and about 13.9% of the world's FDI flows. Over 90% of net capital flows to the Asia Pacific region has been in the form of equity and portfolio investment. By the end of 2004, Asia's share (including Japan) in world equity market capitalization has grown to 21%, with a total market …

Financial Value Of Brands In Mergers And Acquisitions: Is Value In The Eye Of The Beholder?, Cem Badahir, Sundar G.Bharadwaj, Rajendra Kumar Srivastava Jun 2006

Financial Value Of Brands In Mergers And Acquisitions: Is Value In The Eye Of The Beholder?, Cem Badahir, Sundar G.Bharadwaj, Rajendra Kumar Srivastava

Research Collection Lee Kong Chian School Of Business

Firms frequently engage in merger and acquisition deals. In these transactions, brands account for significant but differential proportions of overall transaction value. Extant marketing literature on financial value of brands focuses on drivers of financial value only within a firm. However, in a merger and acquisition context, value of brands also depends on how their new owners might leverage them in the marketplace. This study identifies and empirically tests both the target and acquirer characteristics that affect the value of target firm’s brands in mergers and acquisitions. Furthermore, the authors examine the moderating role of deal type and target firm …

Do Accurate Earnings Forecasts Facilitate Superior Investment Recommendations?, Roger Loh, G. Mujtaba Mian May 2006

Do Accurate Earnings Forecasts Facilitate Superior Investment Recommendations?, Roger Loh, G. Mujtaba Mian

Research Collection Lee Kong Chian School Of Business

We find that analysts who issue more accurate earnings forecasts also issue more profitable stock recommendations. The average factor-adjusted return associated with the recommendations of analysts in the highest accuracy quintile exceeds the corresponding return for analysts in the lowest accuracy quintile by 1.27% per month. Our findings provide indirect empirical support for valuation models in the accounting and finance literatures (e.g., Ohlson, 1995) that emphasize the role of future earnings in predicting stock price movements. Our results also suggest that imperfectly efficient markets reward information gatherers, such as security analysts, for their costly activities in generating superior earnings forecasts.

Loss Function Asymmetry And Forecast Optimality: Evidence From Individual Analysts' Forecasts, Stanimir Markov, Min Yen Tan May 2006

Loss Function Asymmetry And Forecast Optimality: Evidence From Individual Analysts' Forecasts, Stanimir Markov, Min Yen Tan

Research Collection School Of Accountancy

We examine the optimality of quarterly earning forecasts issued by individual analysts. When we conduct Ordinary Least Squares (OLS) and Least Absolute Deviations (LAD) analyses, which assume loss function symmetry, we reject the null of forecast optimality at 5% significance level more than 5% of the time. Relaxing the symmetry assumption reduces the frequency of rejections below 5%. We demonstrate that the cross-sectional variation in the asymmetry parameter of the loss function is related to analyst employment. Overall, our evidence is consistent with the joint hypothesis of asymmetric loss and forecast optimality rather than the alternative of symmetric loss and …

Employee Incentives To Make Firm Specific Investment: Implications For Resource-Based Theories Of Corporate Diversification, Heli Wang, Jay B. Barney Apr 2006

Employee Incentives To Make Firm Specific Investment: Implications For Resource-Based Theories Of Corporate Diversification, Heli Wang, Jay B. Barney

Research Collection Lee Kong Chian School Of Business

We argue that the risk associated with the value of a firm's core resources has an impact on employee decisions to make firm-specific investments, independent of the threat of opportunism that might exist in a particular exchange. We further explore mechanisms firms may adopt to mitigate the employee incentive problem stemming from the risk associated with core resource value. These arguments shed new light on resource-based theories of corporate diversification.

Government Ownership And The Performance Of Government-Linked Companies: The Case Of Singapore, James Ang, David K. Ding Feb 2006

Government Ownership And The Performance Of Government-Linked Companies: The Case Of Singapore, James Ang, David K. Ding

Research Collection Lee Kong Chian School Of Business

In an emerging economy, the alternative to government control is often no governance. We investigate the governance structure of government-linked companies (GLCs) in Singapore under the ownership/control structure of Temasek Holdings, the government holding entity, which typically owns substantial cash flow rights but disproportional control rights and exercises no operational control. We compare the financial and market performance of GLCs with non-GLCs, where each has a different set of governance structure, the key difference being government ownership. We show that Singaporean GLCs have higher valuations and better corporate governance than a control group of non-GLCs. The results hold even when …

Predicting A Currency Crisis Alternative Approaches And Applications To The Philippines, Fernando Antonio Iv Castillo Jan 2006

Predicting A Currency Crisis Alternative Approaches And Applications To The Philippines, Fernando Antonio Iv Castillo

Dissertations and Theses Collection (Open Access)

An arrival of a currency crisis can be anticipated through a comprehensive and properly specified Early Warning System (“EWS”). The costs that entail with experiencing a currency crisis far exceed the costs of spending a considerable amount of time to developing an EWS. In a report done by the IMF(1998), they estimated that emerging economies suffer an 8% cumulative loss in real output during a severe currency crisis. Likewise, evidence suggests that a simple look at traditional market indicators of currency and default risks will not provide much advance warning of an impending currency crisis. In a study done by …

Intraday Stock Prices, Volume, And Duration: A Nonparametric Conditional Density Analysis, Anthony S. Tay, Christopher Ting Jan 2006

Intraday Stock Prices, Volume, And Duration: A Nonparametric Conditional Density Analysis, Anthony S. Tay, Christopher Ting

Research Collection School Of Economics

We investigate the distribution of high-frequency price changes, conditional on trading volume and duration between trades, on four stocks traded on the New York Stock Exchange. The conditional probabilities are estimated nonparametrically using local polynomial regression methods. We find substantial skewness in the distribution of price changes, with the direction of skewness dependent on the sign of trade. We also find that the probability of larger price changes increases with volume, but only for trades that occur with longer durations. The distribution of price changes vary with duration primarily when volume is high.
