Harnessing Digitalization For Sustainable Economic Development: Insights For Asia, John Beirne, David Fernandez
Harnessing Digitalization For Sustainable Economic Development: Insights For Asia, John Beirne, David Fernandez
Research Collection Lee Kong Chian School Of Business
Digitalization has helped to transform economies by enhancing competitiveness and productivity across a wide range of sectors. The use of big data and the rise of online platforms have accelerated this process over the past decade. In addition, the adoption of digital solutions in the face of social distancing and lockdown measures introduced due to the coronavirus disease 2019 (COVID-19) pandemic has been integral to the economic recovery process. The shift to a digitalized economy has also reduced barriers to market entry for firms, lowered inequality, and led to a promotion of social and economic inclusion. Advances in digital technology …
Cross-Cryptocurrency Return Predictability, Li Guo, Bo Sang, Jun Tu, Yu Wang
Cross-Cryptocurrency Return Predictability, Li Guo, Bo Sang, Jun Tu, Yu Wang
Research Collection Lee Kong Chian School Of Business
Using the minute-frequency data on Binance, we find strong evidence of cross-cryptocurrency return predictability. The lagged returns of other cryptocurrencies serve as significant predictors of focal cryptocurrencies up to ten minutes, in line with slow information diffusion. The results are robust across various methods, including the adaptive LASSO and principal component analysis. Furthermore, a long-short portfolio formed on the past returns of cryptocurrencies can generate a daily return of 2.16% out-of-sample after accounting for transaction costs, indicating sizable economic value of cross-cryptocurrency return predictability.
Joint News, Attention Spillover, And Market Returns Predictability, Li Guo, Lin Peng, Yubo Tao, Jun Tu
Joint News, Attention Spillover, And Market Returns Predictability, Li Guo, Lin Peng, Yubo Tao, Jun Tu
Research Collection Lee Kong Chian School Of Business
We analyze over 2.6 million news articles and propose a novel measure of joint news coverage of firms. The measure strongly and negatively predicts market returns, with a monthly R-squared of 3.93% in sample and 6.52% out of sample. The relation is causal, robust to existing predictors, and is especially strong when market uncertainty is high or when market frictions are large. At the firm level, joint news coverage is associated with a 20.3% increase in EDGAR downloads by new IPs from the investor bases of the other covered firms. Our evidence suggests that joint news triggers investor attention spillover …
Algorithmic Transparency, Jian Sun
Algorithmic Transparency, Jian Sun
Research Collection Lee Kong Chian School Of Business
I study the optimal algorithmic disclosure in a lending market where lenders use a predictive algorithm to mitigate adverse selection. The predictive algorithm is unobservable to borrowers and uses a manipulable borrower feature as input. A regulator maximizes market efficiency by disclosing information about the statistical properties of variables embedded in the predictive algorithm to borrowers. Under the optimal disclosure policy, the posterior belief consists of two disjoint regions in which the borrower feature is more relevant and less relevant in predicting borrower quality, respectively. The optimal disclosure policy differentiates posterior lending market equilibria by the equilibrium data manipulation levels. …
Socially Responsible Corporate Customers, Rui Dai, Hao Liang, Lilian Ng
Socially Responsible Corporate Customers, Rui Dai, Hao Liang, Lilian Ng
Research Collection Lee Kong Chian School Of Business
Corporate customers are an important stakeholder in global supply chains. We employ several unique international databases to test whether socially responsible corporate customers can infuse similar socially responsible business behavior in suppliers. Our findings suggest a unilateral effect on corporate social responsibility (CSR) only from customers to suppliers, an evidence further supported by exogenous variation in customers’ close-call CSR proposals and by product scandals. Customers exert influence on suppliers’ CSR through positive assortative matching and their decision-making process. Enhanced collaborative CSR efforts help improve operational efficiency and firm valuation of both customers and suppliers but increase only the customers’ future …
Volatility Timing Under Low-Volatility Strategy, Poh Ling Neo, Chyng Wen Tee
Volatility Timing Under Low-Volatility Strategy, Poh Ling Neo, Chyng Wen Tee
Research Collection Lee Kong Chian School Of Business
The authors show that the slope of the volatility decile portfolio’s return profile contains valuable information that can be used to time volatility under different market conditions in the United States. During good (bad) market conditions, the high- (low-) volatility portfolio produces the highest return. The authors proceed to devise a volatility timing strategy based on statistical tests on the slope of the volatility decile portfolio’s return profile. Volatility timing is achieved by being aggressive during strong growth periods and conservative during market downturns. Superior performance is obtained, with an additional return of 4.1% observed in the volatility timing strategy, …

The global COVID-19 pandemic is now in its second year, and we are fast approaching the third. The year 2021 has brought some hope that vaccination will lead to the end of the pandemic. But it has also brought a more infectious variant of COVID-19 and multiple waves of surging cases that show no immediate sign of disappearing. As the pandemic continues to impact global societies and economies, it is imperative that we study its impact to try and understand how it will affect us in both the short-term and long-term. While the longer-term impacts are still unknown, there is …
Stock Return Prediction Using Financial News: A Unified Sequence Model Based On Hierarchical Attention And Long-Short Term Memory Networks, Haoling Chen, Peng Liu
Stock Return Prediction Using Financial News: A Unified Sequence Model Based On Hierarchical Attention And Long-Short Term Memory Networks, Haoling Chen, Peng Liu
Research Collection Lee Kong Chian School Of Business
Stock return prediction has been a hot topic in both research and industry given its potential for large financial gain. The return signal, apart from its inherent volatility and complexity, is often accompanied by a multitude of noises, such as other stocks’ performance, macroeconomic factors and financial news, etc. To better characterize these factors, we propose a new model that consists of two levels of sequence: an NLP-based module to capture the sequential nature of words and sentences in the financial news, and a time-series-based module to exploit the sequential nature of adjacent observations in the stock price. In this …
Corporate Board Leadership And Earnings Informativeness, Chiyachantana N. Chiraphol, Siripen Pattanawihok, Pattarawan Prasarnphanich
Corporate Board Leadership And Earnings Informativeness, Chiyachantana N. Chiraphol, Siripen Pattanawihok, Pattarawan Prasarnphanich
Research Collection Lee Kong Chian School Of Business
This study examines the relationship between six board compositions and the informativeness of earnings. The results show that smaller board sizes are more informativeness of earnings. Longer board service time is viewed as the experience and expertise to manage the firms and increases informativeness of earnings. The average board tenure is positively significant with the informativeness of earnings. The accounting earnings generated from the firms with more independent directors and female directors are highly valued by the investors. Consequently, the accounting earnings generated from these firms are highly valuable to the investors.

Board Composition, Board Diversity And Stock Performance, Chiyachantana N. Chiraphol, Siripen Pattanawihok, Pattarawan Prrasarnphanich
Research Collection Lee Kong Chian School Of Business
The study investigates the relationship between six board compositions and stock returns. The results indicate a significant association between various board compositions and stock returns. Specifically, board size and executive directors have a negative impact, whereas independent directors enhance stock returns. Busy directors positively impact the abnormal stock returns for the companies in the non-financial industry, which implies that busy directors who serve on more boards tend to be well connected. More importantly, the results indicate a significant positive relationship between board tenure and stock returns. Board service time is perceived as the board quality of knowledge and experience from …

Research Collection Lee Kong Chian School Of Business
This study examines the derivative warrant's profit of issuers compensated with the risk from issuing call and put derivative warrants because they have commitments in risk management and managing risk by hedging the underlying exposure. The average profit of issuers is a cumulative profit from the first trading day until the last trading day. Consistent with the imperfect competition for issuing put derivative warrants on single stock from different securities borrowing and lending advantages, the profit margin of a put warrant is higher than the call warrant. However, the profit margin from a put warrant is not necessarily higher than …
Esg And The Market Return, Ran Chang, Liya Chu, Jun Tu, Bohui Zhang, Guofu Zhou
Esg And The Market Return, Ran Chang, Liya Chu, Jun Tu, Bohui Zhang, Guofu Zhou
Research Collection Lee Kong Chian School Of Business
We propose an environmental, social, and governance (ESG) index. We find that it has significant power in predicting the stock market risk premium, both in- and out-of-sample, and delivers sizable economic gains for mean-variance investors in asset allocation. Although the index is extracted by using the PLS method, its predictability is robust to using alternative machine learning tools. We find further that the aggregate of environmental variables captures short-term forecasting power, while that of social or governance captures long-term. The predictive power of the ESG index stems from both cash flow and discount rate channels.
Faang Stocks, Roger Loh
Faang Stocks, Roger Loh
Research Collection Lee Kong Chian School Of Business
A portfolio of FAANG stocks does not show remarkable outperformance after the acronym was coined. Monthly returns attenuate by more than half after controlling for common factor exposures using traditional or modern asset-pricing models. Alphas in the post-acronym period are not always statistically significant. Pre-acronym alphas are in contrast strong and robust. FAANG-sector stocks comove more with a FAANG portfolio in the post-acronym period. But sorting stocks on their FAANG beta does not earn a reliable return spread. These results might be consistent with investors over-extrapolating the success of hot investing themes, and abnormal profits become less remarkable after popularization.

Tracking Retail Investor Activity, Ekkehart Boehmer, Charles M. Jones, Xiaoyan Zhang, Xinran Zhang
Research Collection Lee Kong Chian School Of Business
We provide an easy method to identify marketable retail purchases and sales using recent, publicly available U.S. equity transactions data. Individual stocks with net buying by retail investors outperform stocks with negative imbalances by approximately 10 bps over the following week. Less than half of the predictive power of marketable retail order imbalance is attributable to order flow persistence, while the rest cannot be explained by contrarian trading (proxy for liquidity provision) or public news sentiment. There is suggestive, but only suggestive, evidence that retail marketable orders might contain firm-level information that is not yet incorporated into prices.
Air Pollution, Behavioral Bias, And The Disposition Effect In China, Jennifer (Jie) Li, Massimo Massa, Hong Zhang, Jian Zhang
Air Pollution, Behavioral Bias, And The Disposition Effect In China, Jennifer (Jie) Li, Massimo Massa, Hong Zhang, Jian Zhang
Research Collection Lee Kong Chian School Of Business
Inspired by the recent health science findings that air pollution affects mental health and cognition, we examine whether air pollution can intensify the cognitive bias observed in the financial markets. Based on a proprietary data set obtained from a large Chinese mutual fund family consisting of complete trading information for more than 773,198 ac-counts in 247 cities, we find that air pollution significantly increases investors' disposition effects. Analysis based on two plausible exogenous variations in air quality (the vast dissi-pation of air pollution caused by strong winds and the Huai River policy) supports a causal interpretation. Mood regulation provides a …

Media Connection And Return Comovement, Zilin Chen, Li Guo, Jun Tu, Jun Tu
Research Collection Lee Kong Chian School Of Business
Media news may cover multiple firms in one article, which establishes a media connection across firms. We propose a media connection strength (MCS) measure between two given firms, which is defined as the number of news articles co-mentioning these two firms. We show that the MCS measure can significantly explain and forecast return comovement of media-connected firm-pairs. Further analyses show that our results are robust to various alternative explanations. We argue that the MCS measure can capture comprehensive and complex correlated fundamental information among media-connected firms and hence may provide a new mechanism for return comovement beyond the existing rational- …
A Dynamic Delegated Investment Model Of Spacs, Dan Luo, Jian Sun
A Dynamic Delegated Investment Model Of Spacs, Dan Luo, Jian Sun
Research Collection Lee Kong Chian School Of Business
We study SPACs in a continuous-time delegated investment model. Our model is built upon three unique features of SPACs: the sponsor and the investor are only partially aligned, a SPAC has a short time horizon, and the investor has the final control over investment approval. Due to the misalignment in incentives, the sponsor has an increasing incentive to propose unprofitable projects to the investor; in response, the investor exerts more stringent screening based on her information. Although the screening helps curb the sponsor’s moral hazard, it also dampens the disciplining effect of partial alignment in incentives. When the investor’s information …
Towards Better Data Augmentation Using Wasserstein Distance In Variational Auto-Encoder, Zichuan Chen, Peng Liu
Towards Better Data Augmentation Using Wasserstein Distance In Variational Auto-Encoder, Zichuan Chen, Peng Liu
Research Collection Lee Kong Chian School Of Business
VAE, or variational auto-encoder, compresses data into latent attributes, and generates new data of different varieties. VAE based on KL divergence has been considered as an effective technique for data augmentation. In this paper, we propose the use of Wasserstein distance as a measure of distributional similarity for the latent attributes, and show its superior theoretical lower bound (ELBO) compared with that of KL divergence under mild conditions. Using multiple experiments, we demonstrate that the new loss function exhibits better convergence property and generates artificial images that could better aid the image classification tasks.
Something In The Air: Does Air Pollution Affect Fund Managers’ Carbon Divestment?, Thanh Huynh, Frank Weikai Li, Ying Xia Xia
Something In The Air: Does Air Pollution Affect Fund Managers’ Carbon Divestment?, Thanh Huynh, Frank Weikai Li, Ying Xia Xia
Research Collection Lee Kong Chian School Of Business
We examine whether fund managers overestimate carbon risk when they are exposed to local air pollution. We find that air pollution causes managers to underweight stocks of high-emission firms. The effects are stronger for less salient scopes of carbon emissions, among managers located in pro-environmental states, and among those likely to be surprised by air pollution—consistent with the idea that managers revise their beliefs about climate-transition risk following their exposure to air pollution. Carbon-intensive stocks sold by managers who are exposed to air pollution subsequently outperform stocks that they buy, suggesting that such underweighting is costly to fund investors.
Greenwashing: Evidence From Hedge Funds, Hao Liang, Lin Sun, Melvyn Teo
Greenwashing: Evidence From Hedge Funds, Hao Liang, Lin Sun, Melvyn Teo
Research Collection Lee Kong Chian School Of Business
We find that a non-trivial number of hedge funds that endorse the United Nations Principles for Responsible Investment indulge in greenwashing. Hedge funds that greenwash underperform both genuinely green and nongreen funds after adjusting for risk. Consistent with an agency explanation, greenwashers (i) underperform more when incentive alignment is poor, (ii) trigger more regulatory violations, and (iii) report more suspicious returns. By exploiting regulatory reforms that aim to enhance stewardship and curb greenwashing, we provide causal evidence that relates agency problems to greenwashing and fund underperformance. Investors, however, do not appear to discriminate between greenwashers and genuinely green funds.
Monetary Policy Surprises, Stock Returns, And Financial And Liquidity Constraints, In An Exchange Rate Monetary Policy System, John M. Sequeira
Monetary Policy Surprises, Stock Returns, And Financial And Liquidity Constraints, In An Exchange Rate Monetary Policy System, John M. Sequeira
Research Collection Lee Kong Chian School Of Business
This study examines the impact of monetary policy surprises on the stock price behaviour of a small developed economy, whose monetary policy is based on the exchange rate. We find that monetary policy surprises associated with all contractionary policy levers and a neutral policy lever, have a consistently significant and negative impact on stock returns. In comparison, only monetary policy surprises associated with a downward re-centering policy lever, has a significantly positive effect on stock returns. Using a recalibrated classification system, we also find that monetary policy surprises differ across sectors of the economy. Our results show how monetary policy …

The COVID-19 pandemic is expected to create the worst economic recession in our lifetime and generate “enormous damage to our health, jobs, and well-being” (OECD, 2020). This special issue focuses on the lessons for accounting and finance policy-makers, practitioners, and academics as a result of the social and economic turmoil that arose in the immediate period following the World Health Organization’s declaration of a pandemic (WHO, 2020). Governments responded to support businesses and economies using various policy tools to support markets, businesses and individuals impacted by the pandemic. It is timely to consider the extent to which policymakers and standard-setters …

Will individuals, especially high-risk individuals, avoid a disease test because of information avoidance? We conduct a field experiment to investigate this issue. We vary the price of a diabetes test (price experiment) and offer both a diabetes test and a cancer test (disease experiment) after eliciting participants’ subjective beliefs about their disease risk. We find evidence that, first, some people avoid the test even when there is neither a monetary nor a transaction cost, and second, both low- and high-risk individuals select out of the test as the price increases. We explain our findings using three classes of models of …
A Unified Market Model For Swaptions And Constant Maturity Swaps, Chyng Wen Tee, Jeroen Kerkhof
A Unified Market Model For Swaptions And Constant Maturity Swaps, Chyng Wen Tee, Jeroen Kerkhof
Research Collection Lee Kong Chian School Of Business
Internal-rate-of-return (IRR) settled swaptions are the main interest rate volatility instruments in the European interest rate markets. Industry practice is to use an approximation formula to price IRR swaptions based on Black model, which is not arbitrage-free. We formulate a unified market model to incorporate both swaptions and constant maturity swaps (CMS) pricing under a single, self-consistent framework. We demonstrate that the model is able to calibrate to market quotes well, and is also able to efficiently price both IRR-settled and swap-settled swaptions, along with CMS products. We use the model to illustrate the difference in implied volatilities for IRR-settled …
Are Disagreements Agreeable? Evidence From Information Aggregation, Dashan Huang, Jiangyuan Li, Liyao Wang
Are Disagreements Agreeable? Evidence From Information Aggregation, Dashan Huang, Jiangyuan Li, Liyao Wang
Research Collection Lee Kong Chian School Of Business
Disagreement measures are known to predict cross-sectional stock returns but fail to predict market returns. This paper proposes a partial least squares disagreement index by aggregating information across individual disagreement measures and shows that this index significantly predicts market returns both in- and out-of-sample. Consistent with the theory in Atmaz and Basak (2018), the disagreement index asymmetrically predicts market returns with greater power in high-sentiment periods, is positively associated with investor expectations of market returns, predicts market returns through a cash flow channel, and can explain the positive volume-volatility relationship.

Research Collection Lee Kong Chian School Of Business
The board of directors plays an important role in implementing corporate governance in the firm, as directors have a fiduciary duty to the firm’s shareholders. The effectiveness of directors is a key determinant of corporate value and they need to bring a range of skills and experience to the boardroom. This skill and experience cannot be developed solely within the firm, and most boards incorporate non-executive directors who are or have been directors of other firms. Current research on the benefits of interlocking directorships is mixed between the claim that they bring outside feedback to the table and open decision …

The limousine service in luxury hotels is an integral component of the whole customer journey in the hospitality industry. One of the largest hotels in Singapore manages a fleet of both in-house and outsourced vehicles around the clock, serving 9,000 trips per month on average. The need for vehicles may scale up rapidly, especially during special events and festive periods in the country. The excess demand is met by having additional outsourced vehicles on standby, incurring millions of dollars of additional expenses per year for the hotel. Determining the required number of limousines by hour of the day is a …
Do Animated Line Graphs Increase Risk Inferences?, Junghan Kim, Arun Lakshmanan
Do Animated Line Graphs Increase Risk Inferences?, Junghan Kim, Arun Lakshmanan
Research Collection Lee Kong Chian School Of Business
This article shows that animated display of time-varying data (e.g., stock or commodity prices) enhances risk judgments. We outline a process whereby animated display enhances the visual salience of transitions in a trajectory (i.e., successive changes in data values), which leads to transitions being utilized more to form cognitive inferences about risk. In turn, this leads to inflated risk judgments. The studies reported in this article provide converging evidence via eye tracking (Study 1), serial mediation analyses (Studies 2 and 3), and experimental manipulations of transition salience (graph type; Study 3) and utilization of transitions (global trend; Study 4 and …

The Pricing Of Initial Public Offering And Market Efficiency, Chiyachantana N. Chiraphol
Research Collection Lee Kong Chian School Of Business
This study investigates long-run performance of Thai initial public offerings (IPOs). To examine the longrun performance of Thai IPOs, we compute buy-and-hold abnormal returns and cumulative abnormal returns for two years after the IPOs. We find strong evidence of long run underpricing in Thai market. Specifically, the average buy-and-hold abnormal returns and cumulative abnormal returns are 64.5% and 18.4% respectively. However, our multi-variate analysis does not indicate a strong relation between long-run underperformance and firm-specific factors, such as firm size, firm age, investment banker reputation and firm profitability.

Hedge Funds And Their Prime Broker Analysts, Sung Gon Chung, Manoj Kulchania, Melvyn Teo
Research Collection Lee Kong Chian School Of Business
Are sell-side analysts reluctant to go against the investment views of their hedge funds when these hedge funds are their prime brokerage clients? We show that prime broker analysts tend to upgrade stocks recently bought by their clients. For stocks with upgraded recommendations, post-announcement cumulative abnormal returns are significantly lower for those purchased by the prime brokerage clients. Our results are stronger with high-dollar-turnover clients who generate more trading commissions. We also find that a hedge fund with a large bet on a stock has a stronger incentive to pressure the fund’s prime brokers to issue a favorable recommendation on …
