Stochastic Capacity Investment And Flexible Vs. Dedicated Technology Choice In Imperfect Capital Markets, Onur Boyabatli, L. Bertil Toktay
Stochastic Capacity Investment And Flexible Vs. Dedicated Technology Choice In Imperfect Capital Markets, Onur Boyabatli, L. Bertil Toktay
Research Collection Lee Kong Chian School Of Business
This paper analyzes the impact of endogenous credit terms under capital market imperfections in a capacity investment setting. We model a monopolist firm that decides on its technology choice (flexible versus dedicated) and capacity level under demand uncertainty. Differing from the majority of the stochastic capacity investment literature, we assume that the firm is budget constrained and can relax its budget constraint by borrowing from a creditor. The creditor offers technology-specific loan contracts to the firm, after which the firm makes its technology choice and subsequent decisions. Capital market imperfections impose financing frictions on the firm. Our analysis contributes to …
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 …

Although annuities are a theoretically appealing way to manage longevity risk, in the real world relatively few consumers purchase them at retirement. To counteract the possibility of retirees outliving their assets, Singapore’s Central Provident Fund, a national defined contribution pension scheme, has recently mandated annuitization of workers’ retirement assets. More significantly, the government has entered the insurance market as a public sector provider for such annuities. This article evaluates the money’s worth of life annuities and discusses the impact of the government mandate and its role as an annuity provider on the insurance market.
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 …
Acquisitions Driven By Stock Overvaluation: Are They Good Deals?, Fangjian Fu, Leming Lin, Micah Officer
Acquisitions Driven By Stock Overvaluation: Are They Good Deals?, Fangjian Fu, Leming Lin, Micah Officer
Research Collection Lee Kong Chian School Of Business
Overvaluation may motivate a firm to use its stock to acquire a target whose stock is not as overpriced (Shleifer and Vishny (2003)). Though hypothetically desirable, these acquisitions in practice create little, if any, value for acquirer shareholders. Two factors often impede value creation: payment of a large premium to the target and lack of economic synergies in the acquisition. We find that overvaluationdriven stock acquirers suffer worse operating performance and lower long-run stock returns than control firms that are in the same industry, similarly overvalued at the same time, have similar size and Tobin’s q, but have not pursued …
Asset Performance Evaluation With Mean-Variance Ratio, Zhidong Bai, Kok Fai Phoon, Keyan Wang, Wing-Keung Wong
Asset Performance Evaluation With Mean-Variance Ratio, Zhidong Bai, Kok Fai Phoon, Keyan Wang, Wing-Keung Wong
Research Collection Lee Kong Chian School Of Business
Bai, et al. (2011c) develop the mean-variance-ratio (MVR) statistic to test the performance among assets for small samples. They provide theoretical reasoning to use MVR and prove that our proposed statistic is uniformly most powerful unbiased. In this paper we illustrate the superiority of our proposed test over the Sharpe ratio (SR) test by applying both tests to analyze the performance of Commodity Trading Advisors (CTAs). Our findings show that while the SR test concludes most of the CTA funds being analyzed as being indistinguishable in their performance, our proposed statistics show that some funds outperform the others. On the …
Do Merger-Related Operating Synergies Exist?, Gennaro Bernile, Scott W. Bauguess
Do Merger-Related Operating Synergies Exist?, Gennaro Bernile, Scott W. Bauguess
Research Collection Lee Kong Chian School Of Business
Executives frequently forecast large operating efficiency gains from mergers. Using these projections, we study the impact of operating synergies on merger performance. Investors' reaction to mergers varies directly with the availability of these forecasts and the gains they imply, and post-merger operating performance increases with the predictable component of forecasted synergies based on deal characteristics. The realized improvements, however, do not depend on the availability of forecasts or the surprise they convey, and post-merger stock returns reconcile discrepancies between investors' ex ante beliefs and mergers' ex post performance related to management forecasts. Overall, the evidence supports the neoclassical view that …
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 …
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 …

Financial Hedging Decision On Procurement Risk For Newsvendor Model With Value-At-Risk Constraint, Yuan Wen, Qing Ding, Jian Chen
Research Collection Lee Kong Chian School Of Business
Manufacturers must now deal with increasingly fluctuating procurement prices for commodities and industrial component parts. However, it is hard for them to pass cost increases on to downstream markets efficiently. Therefore, manufacturers have sought to solve this problem with various supply management tactics. While vertical integration of key suppliers or signing long-term contracts is possible, financial hedging emerges as the most effective approach to counter commodities price risks. In situations where market demand uncertainty is still unresolved and often interplays with upstream price volatilities, Value-at-Risk (VaR) can help managers handle the multi-fold uncertainties and their potential interactions, by effectively measuring …
The Implications Of Sovereign Wealth Fund Investment On Capital Markets: A Bottom-Up View, David Fernandez
The Implications Of Sovereign Wealth Fund Investment On Capital Markets: A Bottom-Up View, David Fernandez
Research Collection Lee Kong Chian School Of Business
The buzz around sovereign wealth funds has been turned down a notch, but they remain a hot topic. The accusations of sovereign wealth funds having hidden agendas remain, but with the very public losses suffered by some during the recent financial turmoil, such talk has even less credibility. And given that most of those losses were from investments in US, UK, and European financial institutions, hope that sovereign wealth funds would be the saviors of Wall Street has also faded. At its base, four trends continue to keep sovereign wealth funds in focus. First, there is the phenomenal rise of …

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 …

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 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.

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
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 …
The Unintended Effects Of The Sarbanes-Oxley Act, Vidhi Chhaochharia, Clemens A. Otto, Vikrant Vig
The Unintended Effects Of The Sarbanes-Oxley Act, Vidhi Chhaochharia, Clemens A. Otto, Vikrant Vig
Research Collection Lee Kong Chian School Of Business
The Sarbanes-Oxley Act (SOX) was passed in the wake of several scandals that rocked corporate America in 2001 and 2002. The objective behind SOX was to improve corporate governance by improving accounting disclosures. Compliance with Section 404 is considered by many to be the most costly requirement of SOX and has been argued to be a disproportionate burden for small firms. Consequently, firms with a public float below $75 million were granted several exemptions from compliance. We document an unintended effect of these exemptions: a weakening of corporate governance through a weakening of the market for corporate control.

Pairwise Correlations, Tarun Chordia, Amit Goyal, Qing Tong
Research Collection Lee Kong Chian School Of Business
Pairwise stock correlations increase by 27% on average when stock returns are negative. It is trading activity in small stocks that leads to higher correlations when returns are negative. We provide evidence consistent with the hypothesis that co-ordinated selling by retail investors drives this asymmetry in correlations. The co-ordinated selling activity by retail investors is triggered by negative market returns.

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 …
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
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 …

Understanding Investor Sentiment: The Case Of Soccer, Gennaro Bernile, Evgeny Lyandres
Research Collection Lee Kong Chian School Of Business
We examine the extent to which the stock market's inefficient responses to resolutions of uncertainty depend on investors’ biased ex ante beliefs regarding the probability distribution of future event outcomes or their ex post irrational reactions to these outcomes. We use a sample of publicly traded European soccer clubs and analyze their returns around important matches. Using a novel proxy for investors’ expectations based on contracts traded on betting exchanges (prediction markets), we find that within our sample, investor sentiment is attributable, in part, to a systematic bias in investors’ ex ante expectations. Investors are overly optimistic about their teams’ …
