An Improved Test For Statistical Arbitrage, Robert Jarrow, Melvyn Teo, Yiu Kuen Tse, Mitch Warachka
An Improved Test For Statistical Arbitrage, Robert Jarrow, Melvyn Teo, Yiu Kuen Tse, Mitch Warachka
Research Collection Lee Kong Chian School Of Business
We improve upon the power of the statistical arbitrage test in Hogan, Jarrow, Teo, and Warachka (2004). Our methodology also allows for the evaluation of return anomalies under weaker assumptions. We then compare strategies based on their convergence rates to arbitrage and identify strategies whose probability of a loss declines to zero most rapidly. These strategies are preferred by investors with finite horizons or limited capital. After controlling for market frictions and examining convergence rates to arbitrage, we find that momentum and value strategies offer the most desirable trading opportunities.
Frog In The Pan: Continuous Information And Momentum, Zhi Da, G. Gurun, Mitchell Craig Warachka
Frog In The Pan: Continuous Information And Momentum, Zhi Da, G. Gurun, Mitchell Craig Warachka
Research Collection Lee Kong Chian School Of Business
We develop and test a frog-in-the-pan hypothesis that predicts investors are less attentive to information arriving continuously in small amounts than to information with the same cumulative stock price implications arriving in large amounts at discrete timepoints. Intuitively, we hypothesize that a series of gradual frequent changes attracts less attention than infrequent dramatic changes. Consistent with our frog-in-the-pan hypothesis, we find strong evidence that continuous information induces stronger and more persistent return continuation. Over a six-month holding period, momentum decreases monotonically from 8.86% for stocks with continuous information during their formation period to 2.91% for stocks with discrete information. Higher …
A Multiechelon Inventory Problem With Secondary Market Sales, Alexandar Angelus
A Multiechelon Inventory Problem With Secondary Market Sales, Alexandar Angelus
Research Collection Lee Kong Chian School Of Business
We consider a finite-horizon, multiechelon inventory system in which the surplus of stock can be sold (i.e., disposed) in the secondary markets at each stage in the system. What are called nested echelon order-up-to policies are shown to be optimal for jointly managing inventory replenishments and secondary market sales. Under a general restriction on model parameters, we establish that it is optimal not to both sell off excess stock and replenish inventory. Secondary market sales complicate the structure of the system, so that the classical Clark and Scarf echelon reformulation no longer allows for the decomposition of the objective function …
Charting Your Financial Goals, Benedict Koh
Charting Your Financial Goals, Benedict Koh
Research Collection Lee Kong Chian School Of Business
Every one of us has financial goals but not many of us know how to go about achieving them. We often lack investment knowledge or expertise to design an investment plan that optimises our savings. Consequently, we adopt the default approach of leaving all our savings in bank deposits. By doing so, we have already made an asset allocation decision, one that is very conservative. Over time, we soon realise that this conservative investment plan is simply not working as our savings are not compounding fast enough to keep up with inflation. We need to invest more wisely so that …
What Is Behind The Asset Growth And Investment Growth Anomalies?, Fangjian Fu
What Is Behind The Asset Growth And Investment Growth Anomalies?, Fangjian Fu
Research Collection Lee Kong Chian School Of Business
Existing studies show that firm asset and investment growth predict cross-sectional stock returns. Firms that shrink their assets or investments subsequently earn higher returns than firms that expand their assets or investments. I show that the superior returns of the low asset and investment growth portfolios are due to the omission of delisting returns in CRSP monthly stock return file and that the poor returns of the high asset and investment growth portfolios are largely driven by the subsample of firms that have issued large amounts of debt or equity in the previous year. Controlling for the effects of the …

Size And Return: A New Perspective, Fangjian Fu, Wei Yang
Size And Return: A New Perspective, Fangjian Fu, Wei Yang
Research Collection Lee Kong Chian School Of Business
We document robust empirical evidence that, after controlling for idiosyncratic volatility, large stocks earn significantly higher returns than small stocks. Our empirical results indicate that idiosyncratic volatility is positively related to return, but negatively related to size. Hence, failure to control for idiosyncratic volatility generates a downward omitted variable bias and leads to the widely documented negative relation between size and return. We explain the two contrasting size-return relations, with and without the control for idiosyncratic volatility, in a parsimonious equilibrium model that incorporates three empirical regularities: some individual investors are under-diversified; small stocks have higher idiosyncratic volatilities than large …
Leverage Change, Debt Overhang, And Stock Prices, Jie Cai, Zhe Zhang
Leverage Change, Debt Overhang, And Stock Prices, Jie Cai, Zhe Zhang
Research Collection Lee Kong Chian School Of Business
We document a significant and negative effect of the change in a firm's leverage ratio on its stock prices. We find that the negative effect is stronger for firms that have higher leverage ratios, higher likelihood of default, and face more severe financial constraints. Moreover, firms with an increase in leverage ratio tend to have less future investment. These findings are consistent with Myers' (1977) debt overhang theory that an increase in leverage may lead to future underinvestment, thus reducing a firm's value.
Adverse Selection And Corporate Governance, Charlie Charoenwong, David K. Ding, Vasan Siraprapasiri
Adverse Selection And Corporate Governance, Charlie Charoenwong, David K. Ding, Vasan Siraprapasiri
Research Collection Lee Kong Chian School Of Business
This paper examines the impact of corporate governance on the adverse selection component of the bid-ask spread of stocks listed on the Singapore Exchange. These companies have been identified by Credit Lyonnais Securities Asia (CSLA) with the highest level of corporate governance among 25 emerging markets. We measure corporate governance by several criteria: discipline, transparency, independence, accountability, responsibilities, fairness, and social awareness. The results show that corporate governance has an inverse relationship with adverse selection. However, only the transparency dimension exhibits a significant inverse relationship with adverse selection. In addition, Government-Linked Companies (GLCs) are shown to have a smaller adverse …
An Analysis Of Japanese Earnings Forecast Revisions With Application To Seasoned Equity Offerings, Gary L. Caton, Justin S. P. Chan, Jeremy C. Goh, Sheng Yung Yang
An Analysis Of Japanese Earnings Forecast Revisions With Application To Seasoned Equity Offerings, Gary L. Caton, Justin S. P. Chan, Jeremy C. Goh, Sheng Yung Yang
Research Collection Lee Kong Chian School Of Business
Using the bootstrap method, we explore the characteristics of revisions in Japanese earnings forecast data. We find that forecast revisions exhibit a downward trend over time as the actual earnings announcement date approaches, and are serially correlated with three significant lags. Using these characteristics we develop a model to estimate abnormal forecast revisions, and illustrate the model's use with a sample of Japanese companies announcing seasoned equity offerings (SEOs). In contrast to results obtained by studies using American data, our findings indicate significant positive upward revisions when Japanese firms announce an SEO.
Valuation Of Risky Projects And Other Illiquid Investments Using Portfolio Selection Models, Janne Gustafsson, Bert De Reyck, Zeger Degraeve, Ahti Salo
Valuation Of Risky Projects And Other Illiquid Investments Using Portfolio Selection Models, Janne Gustafsson, Bert De Reyck, Zeger Degraeve, Ahti Salo
Research Collection Lee Kong Chian School Of Business
We develop a portfolio selection framework for the valuation of projects and other illiquid investments for an investor who can invest in a portfolio of private, illiquid investment opportunities as well as in securities in financial markets, but who cannot necessarily replicate project cash flows using financial instruments. We demonstrate how project values can be solved using an inverse optimization procedure and prove several general analytical properties for project values. We also provide an illustrative example on the modeling and pricing of multiperiod projects that are characterized by managerial flexibility.
Earnings Management Surrounding Seasoned Bond Offerings: Do Managers Mislead Ratings Agencies And The Bond Market, Gary L. Gaton, Chiraphol New Chiyachantana, Choong Tze Chua, Jeremy Goh
Earnings Management Surrounding Seasoned Bond Offerings: Do Managers Mislead Ratings Agencies And The Bond Market, Gary L. Gaton, Chiraphol New Chiyachantana, Choong Tze Chua, Jeremy Goh
Research Collection Lee Kong Chian School Of Business
We study earnings management (EM) efforts surrounding seasoned bond offerings using discretionary current accruals. We find that issuers tend to inflate earnings performance prior to an offering. In order for EM efforts to effectively mislead ratings agencies and the bond market, they must lead to inflated bond ratings and decreased offering yields. Regression results indicate the opposite; aggressive EM efforts are associated with lower initial ratings and higher offering yields. We also find a statistically lower proportion of subsequent downgrades for firms with the most aggressive EM efforts, which is inconsistent with these firms’ inflated initial ratings. While some firms …
Investor Heterogeneity, Investor-Management Agreement And Open Market Share Repurchase, Sheng Huang, Anjan V. Thakor
Investor Heterogeneity, Investor-Management Agreement And Open Market Share Repurchase, Sheng Huang, Anjan V. Thakor
Research Collection Lee Kong Chian School Of Business
This paper develops and tests a new theoretical explanation for why a firm conducts open-market stock repurchases. Investors may disagree with the manager about the firm’s investment projects. A repurchase causes a change in the investor base as investors who are more likely to disagree with the manager tender their shares. This model leads to the following predictions: first, a firm is more likely to buy back shares when the level of investor-management agreement is low, and second, the level of agreement improves following a repurchase. Our empirical tests provide strong support for these predictions. The results are robust to …
The Disparity Between Long-Term And Short-Term Forecasted Earnings Growth, Zhi Da, Mitchell Craig Warachka
The Disparity Between Long-Term And Short-Term Forecasted Earnings Growth, Zhi Da, Mitchell Craig Warachka
Research Collection Lee Kong Chian School Of Business
We find the disparity between long-term and short-term analyst forecasted earnings growth is a robust predictor of future returns and long-term analyst forecast errors. After adjusting for industry characteristics, stocks whose long-term earnings growth forecasts are far above or far below their implied short-term forecasts for earnings growth have negative and positive subsequent risk-adjusted returns along with downward and upward revisions in long-term forecasted earnings growth, respectively. Additional results indicate that investor inattention toward firm-level changes in long-term earnings growth is responsible for these risk-adjusted returns.
How Important Are Earnings Announcements As An Information Source?, Sudipta Basu, Truong Xuan Duong, Stanimir Markov, Eng Joo Tan
How Important Are Earnings Announcements As An Information Source?, Sudipta Basu, Truong Xuan Duong, Stanimir Markov, Eng Joo Tan
Research Collection Lee Kong Chian School Of Business
In a competitive information market, a single information source can only dominate other sources individually, not collectively. We explore whether earnings announcements constitute such a dominant source using Ball and Shivakumar's (2008) [How much new information is there in earnings?, Journal of Accounting Research, 2008, 46(5), pp. 975–1016] R 2 metric: the proportion of the variation in annual returns explained by the four quarterly earnings announcement returns. We find that the earnings announcement days' R 2 is 11% – higher than the corresponding R 2 of days with dividend announcements, management forecasts, preannouncements, and 10-K and 10-Q filings and …
The Liquidity Risk Of Liquid Hedge Funds, Melvyn Teo
The Liquidity Risk Of Liquid Hedge Funds, Melvyn Teo
Research Collection Lee Kong Chian School Of Business
This paper evaluates hedge funds that grant favorable redemption terms to investors. Within this group of purportedly liquid funds, high net inflow funds subsequently outperform low net inflow funds by 4.79% per year after adjusting for risk. The return impact of fund flows is stronger when funds embrace liquidity risk, when market liquidity is low, and when funding liquidity, as measured by the Treasury-Eurodollar spread, aggregate hedge fund flows, and prime broker stock returns, is tight. In keeping with an agency explanation, funds with strong incentives to raise capital, low manager option deltas, and no manager capital co-invested are more …
Consolidating Information In Option Transactions, Richard Holowczak, Jianfeng Hu, Liuren Wu
Consolidating Information In Option Transactions, Richard Holowczak, Jianfeng Hu, Liuren Wu
Research Collection Lee Kong Chian School Of Business
Underlying each stock trades hundreds of options at different strike prices and maturities. The order flows from these option transactions reveal important information about the underlying stock price. How to aggregate the trade information of different option contracts underlying the same stock presents an interesting and important question for developing microstructure theories and price discovery mechanisms in the derivatives markets. This paper takes options on QQQQ, the Nasdaq 100 tracking stock, as an example and examines different order flow consolidation mechanisms in terms of their effectiveness in extracting information about the underlying stock price and volatility movements. The analysis leads …

Hedge Funds, Managerial Skill, And Macroeconomic Variables, Doron Avramov, Robert Kosowski, Narayan Y. Naik, Melvyn Teo
Research Collection Lee Kong Chian School Of Business
This paper evaluates hedge fund performance through portfolio strategies that incorporate predictability based on macroeconomic variables. Incorporating predictability substantially improves out-of-sample performance for the entire universe of hedge funds as well as for various investment styles. While we also allow for predictability in fund risk loadings and benchmark returns, 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% per year. The economic value of predictability obtains for different rebalancing horizons and alternative benchmark models. It is also robust …
Ipo Timing, Buyout Sponsors’ Exit Strategies And Firm Performance Of Rlbos, Jerry Xiaping Cao
Ipo Timing, Buyout Sponsors’ Exit Strategies And Firm Performance Of Rlbos, Jerry Xiaping Cao
Research Collection Lee Kong Chian School Of Business
This paper studies the impact of buyout sponsors’ IPO timing on the LBO restructuring process and subsequent exit strategies. I find that LBO duration is negatively related to hot IPO market conditions. Further, following IPOs, RLBOs with shorter LBO duration experience greater deterioration of performance and higher probability of bankruptcy. This suggests that sponsor’s efforts to enhance operating efficiency succumb to market timing. IPO timing does not affect sponsor’s exit strategies and monitoring post IPO. Sponsors keep an active long-run presence with more reputable sponsors more likely to exit by facilitating takeovers.
When Are Analyst Recommendation Changes Influential?, Roger Loh, Rene M. Stulz
When Are Analyst Recommendation Changes Influential?, Roger Loh, Rene M. Stulz
Research Collection Lee Kong Chian School Of Business
The existing literature measures the contribution of analyst recommendation changes using average stock-price reactions. With such an approach, recommendation changes can have a significant impact even if no recommendation has a visible stock-price impact. Instead, we call a recommendation change influential only if it affects the stock price of the affected firm visibly. We show that only 12% of recommendation changes are influential. Recommendation changes are more likely to be influential if they are from leader, star, previously influential analysts, issued away from consensus, accompanied by earnings forecasts, and issued on growth, small, high institutional ownership, or high forecast dispersion …
Out-Of-Sample Industry Return Predictability: Evidence From A Large Number Of Predictors, David E. Rapach, Jack K. Strauss, Jun Tu, Guofu Zhou
Out-Of-Sample Industry Return Predictability: Evidence From A Large Number Of Predictors, David E. Rapach, Jack K. Strauss, Jun Tu, Guofu Zhou
Research Collection Lee Kong Chian School Of Business
We uncover extensive evidence of out-of-sample return predictability for industry portfolios based on a principal component approach that incorporates information from a large number of predictors. Moreover, we find substantial differences in the degree of return predictability across industries. To understand these differences, we propose a decomposition of out-of-sample industry return predictability into beta and alpha shares, where the former corresponds to a conditional beta pricing model. A conditional version of the popular Fama-French three-factor model accounts for nearly all out-of-sample industry return predictability, with exposures to time-varying market and size risk premiums especially important for explaining differences in return …
Markowitz Meets Talmud: A Combination Of Sophisticated And Naive Diversification Strategies, Jun Tu, Guofu Zhou
Markowitz Meets Talmud: A Combination Of Sophisticated And Naive Diversification Strategies, Jun Tu, Guofu Zhou
Research Collection Lee Kong Chian School Of Business
The modern portfolio theory pioneered by Markowitz (1952) is widely used in practice and extensively taught to MBAs. However, the estimated Markowitz portfolio rule and most of its extensions not only underperform the naive 1/N rule (that invests equally across N assets) in simulations, but also lose money on a risk-adjusted basis in many real data sets. In this paper, we propose an optimal combination of the naive 1/N rule with one of the four sophisticated strategies—the Markowitz rule, the Jorion (1986) rule, the MacKinlay and Pástor (2000) rule, and the Kan and Zhou (2007) rule—as a way to improve …
Bayesian Analysis Of Structural Credit Risk Models With Microstructure Noises, Shirley J. Huang, Jun Yu
Bayesian Analysis Of Structural Credit Risk Models With Microstructure Noises, Shirley J. Huang, Jun Yu
Research Collection Lee Kong Chian School Of Business
In this paper a Markov chain Monte Carlo (MCMC) technique is developed for the Bayesian analysis of structural credit risk models with microstructure noises. The technique is based on the general Bayesian approach with posterior computations performed by Gibbs sampling. Simulations from the Markov chain, whose stationary distribution converges to the posterior distribution, enable exact finite sample inferences of model parameters. The exact inferences can easily be extended to latent state variables and any nonlinear transformation of state variables and parameters, facilitating practical credit risk applications. In addition, the comparison of alternative models can be based on devian information criterion …
Do Foreign Institutions Improve Stock Liquity?, Chi Shen Wei
Do Foreign Institutions Improve Stock Liquity?, Chi Shen Wei
Research Collection Lee Kong Chian School Of Business
This paper examines whether capital flows by foreign institutions improve liquidity in domestic markets. I find that stocks with increased foreign institutional ownership subsequently experience higher liquidity. However, it is difficult to interpret this evidence as a causal relation because institutions tend to self-select into more liquid stocks. To solve this problem, I exploit the 2003 US dividend tax cut as a natural experiment. The results from a 2SLS (IV) regression confirm that liquidity improved more in dividend-paying stocks located in US tax-treaty countries compared to similar stocks located in non-treaty countries. These patterns are consistent with the notion that …
International Diversification With Factor Funds, Cheol S. Eun, Sandy Lai, Frans A. De Roon, Zhe Zhang
International Diversification With Factor Funds, Cheol S. Eun, Sandy Lai, Frans A. De Roon, Zhe Zhang
Research Collection Lee Kong Chian School Of Business
We propose a new investment strategy employing “factor funds” to systematically enhance the mean-variance efficiency of international diversification. Our approach is motivated by the increasing evidence that size (SMB), book-to-market (HML), and momentum (MOM) factors, along with the market factor, adequately describe international stock returns, and by the direct link between investors’ portfolio choice problems and international asset pricing theories and tests. Using data from ten developed countries during the period 1981-2008, we show that the “augmented” optimal portfolio involving local factor funds substantially outperforms the “benchmark” optimal portfolio comprising country market indices only as measured by their portfolio Sharpe …
Investing Into The Abyss: The Continued Misclassification Of Multi-Sector Managed Funds, John R Watson, N. Allen, Kok Fai Phoon, J. Wickramanayake
Investing Into The Abyss: The Continued Misclassification Of Multi-Sector Managed Funds, John R Watson, N. Allen, Kok Fai Phoon, J. Wickramanayake
Research Collection Lee Kong Chian School Of Business
The objective of this paper is to assess whether Australian multi-sector managed funds are misclassified, and then, having found this to be the case, determine if this misclassification has any impact on fund performance. We adopt a strong form of returns based style analysis to investigate a monthly sample of Australian multi-sector funds over the five-year sample period 2003:04-2008:03. The evidence provided demonstrates that insufficient attention has been paid as to whether fund managers are able to keep within their tactical asset allocation ranges and presents that misclassification exist for Australian multi-sector managed funds but that the effect on fund …
Investor Inattention And The Underreaction To Stock Recommendations, Roger Loh
Investor Inattention And The Underreaction To Stock Recommendations, Roger Loh
Research Collection Lee Kong Chian School Of Business
Investors’ reaction to stock recommendations is often incomplete so that there is a predictable post-recommendation drift. I investigate investor inattention as a plausible explanation for this drift by using prior turnover as a proxy for attention. I find that low attention stocks react less to stock recommendations than high attention stocks around the three-day event window. Subsequently, the recommendation drift of firms with low attention is more than double in magnitude when compared to firms with high attention. Similar conclusions are reached with alternative proxies for attention. The evidence supports investor inattention as a source of the stock recommendation drift.

This study examines trade sizes used by informed traders. The selected sample includes 73 active stocks from the Stock Exchange of Thailand (SET), a pure limit order market, that cover two distinct market conditions of a bull and bear market. Using intraday data, the study finds that large sized trades (i.e., larger than the 75th percentile) account for a disproportionately large impact on changes in traded and quoted prices. This finding compares with the results of studies conducted on U.S. markets that show informed traders employ trade sizes falling between the 40th and 95th percentiles (Barclay and Warner 1993; Chakravarty …
A Dynamic Model For The Forward Curve, Choong Tze Chua, Foster Dean, Krishna Ramaswamy, Robert Stine
A Dynamic Model For The Forward Curve, Choong Tze Chua, Foster Dean, Krishna Ramaswamy, Robert Stine
Research Collection Lee Kong Chian School Of Business
This article develops and estimates a dynamic arbitrage-free model of the current forward curve as the sum of (i) an unconditional component, (ii) a maturity-specific component and (iii) a date-specific component. The model combines features of the Preferred Habitat model, the Expectations Hypothesis (ET) and affine yield curve models; it permits a class of low-parameter, multiple state variable dynamic models for the forward curve. We show how to construct alternative parametric examples of the three components from a sum of exponential functions, verify that the resulting forward curves satisfy the Heath-Jarrow-Morton (HJM) conditions, and derive the risk-neutral dynamics for the …
Incorporating Economic Objectives Into Bayesian Priors: Portfolio Choice Under Parameter Uncertainty, Jun Tu, Guofu Zhou
Incorporating Economic Objectives Into Bayesian Priors: Portfolio Choice Under Parameter Uncertainty, Jun Tu, Guofu Zhou
Research Collection Lee Kong Chian School Of Business
This paper proposes a way to allow Bayesian priors to reflect the objectives of an economic problem. That is, we impose priors on the solution to the problem rather than on the primitive parameters whose implied priors can be backed out from the Euler equation. Using monthly returns on the Fama-French 25 size and book-to-market portfolios and their 3 factors from January 1965 to December 2004, we find that investment performances under the objective-based priors can be significantly different from those under alternative priors, with differences in terms of annual certainty-equivalent returns greater than 10% in many cases. In terms …
