A Little Birdy Told Me: Analysis Of The Impact Of Public Tweet Sentiment On Stock Prices, Alexander Novitsky

CMC Senior Theses

The combination of the advent of the internet in 1983 with the Securities and Exchange Commission’s ruling allowing firms the use of social media for public disclosures merged to create a wealth of user data that traders could quickly capitalize on to improve their own predictive stock return models. This thesis analyzes some of the impact that this new data may have on stock return models by comparing a model that uses the Index Price and Yesterday’s Stock Return to one that includes those two factors as well as average tweet Polarity and Subjectivity. This analysis is done with ten …

The Performance Of Stock Portfolios: Evidence From Analysing Malaysia Case, And Implication For Open Innovation, Ariful Hoque, Sharmeen Rakhi, Kamrul Hassan, Thi Le

Research outputs 2014 to 2021

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. This research examines the performance of the Islamic stock portfolio (ISP) and conventional stock portfolio (CSP) for the five industrial sectors and market in Malaysia. The capital asset pricing model statistics indicate that the ISP provides a higher return with a lower systematic risk compared to the CSP in different sectors; however, the ISP and CSP perform equally in the market. The non-parametric stochastic dominance approach reveals that the ISP is better than the CSP for portfolio return without considering the riskiness for all sectors except properties; further, the ISP outperforms …

Initial Public Offerings And Pricing Anomalies, Hon Wei Leow

Student Works (2020-2029)

Initial Public Offering (IPO) is a form of fundraising through the stock market of which has evolved as an essential platform to study the performance of newly issued shares. In the case of an emerging market like Malaysia, the pricing anomalies that measure the performance of initial return and flipping activity of IPO remain an interesting subject. During the period of Global Financial Crisis (GFC) in 2008-09, it is believed that the market sentiment will affect the initial return of new IPO and oversubscription will be negative, and hence firms will be unwilling to do the new listing on the …

Sell-Side Analysts' Benchmarks, Ohad Kadan, Leonardo Madureira, Rong Wang, Tzachi Zach

Research Collection Lee Kong Chian School Of Business

Sell-side analysts employ different benchmarks when defining their recommendations. A buy for some brokers means the stock is expected to outperform its industry, while for other brokers it means the stock is expected to outperform the market, or some return threshold. We show that these stated benchmarks have implications for the distribution of recommendations, price reactions to recommendations, and the investment value of recommendations. We conclude that, depending on the question, academics may need to account for the benchmarks when studying analysts’ outputs, and investors may find the benchmarks beneficial in interpreting analysts’ advice.

A Learning Curve Of The Market: Chasing Alpha Of Socially Responsible Firms, Zhichuan Li, Jun Wang, Dylan Minor, Chongyu Dang

Business Publications

This paper explores stock market reactions to corporate social performance. We find that a value-weighted portfolio based on the list of “100 Best CSR companies in the world”, published by Reputation Institute, yields statistically significant annual abnormal returns of 1.63% and 1.26%, by controlling for Carhart four factors and Fama-French five factors, respectively (2.39% and 1.84% respectively for an equal-weighted portfolio). Moreover, such abnormal returns decrease as time goes, especially after the inaugural publication of the CSR lists in 2013. The paper also indicates that companies with better social performance are more likely to have positive earnings surprises, and that …

Chasing Private Information, Marcin Kacperczyk, Emiliano Sebastian Pagnotta

Research Collection Lee Kong Chian School Of Business

Using over 5,000 trades unequivocally based on nonpublic information about firm fundamentals, we find that asymmetric information proxies display abnormal values on days with informed trading. Volatility and volume are abnormally high, whereas illiquidity is low, in equity and option markets. Daily returns reflect the sign of private signals, but bid-ask spreads are lower when informed investors trade. Market makers' learning under event uncertainty and limit orders help explain these findings. The cross-section of information duration indicates that traders select days with high uninformed volume. Evidence from the U.S. SEC Whistleblower Reward Program and the FINRA involvement addresses selection concerns.

Regulations And Brain Drain: Evidence From Wall Street Star Analysts’ Career Choices, Yuyan Guan, Congcong Li, Hai Lu, Franco Wong

Research Collection School Of Accountancy

The Global Settlement, along with related regulations in the early 2000s, prohibits the use of investment banking revenue to fund equity research and compensate equity analysts. We find that all-star analysts from investment banks are more likely to exit the profession or move to the buy side after the regulations. The departed star analysts’ earnings revisions and stock recommendations are more informative than those of the remaining analysts who followed the same companies. To the extent that star analysts are superior to their nonstar counterparts in terms of research ability and ability to inform the market, the exit of star …

Center Of Volume Mass: Does Options Trading Predict Stock Returns?, Gennaro Bernile, Fei Gao, Jianfeng Hu

Research Collection Lee Kong Chian School Of Business

We examine whether the distribution of trades along the set of strike prices of option contracts on the same stock contains information about underlying price discovery. We show that option traders' demand for delta exposure drives the volume-weighted average strike-spot price ratio (VWKS). In turn, we find that VWKS predicts underlying returns and anticipates the flow of fundamental information about the stock. The return predictability is greater but not limited to stocks with higher information asymmetries and arbitrage costs, and becomes stronger ahead of value relevant news. Overall, options trading appears to play an important informational role for underlying markets.

Behavioral Agent-Based Framework For Interacting Financial Markets, Heba M. Ezzat Dr.

Business Administration

Purpose – This paper aims at developing a behavioral agent-based model for interacting financial markets. Additionally, the effect of imposing Tobin taxes on market dynamics is explored. Design/methodology/approach – The agent-based approach is followed to capture the highly complex, dynamic nature of financial markets. The model represents the interaction between two different financial markets located in two countries. The artificial markets are populated with heterogeneous, boundedly rational agents. There are two types of agents populating the markets; market makers and traders. Each time step, traders decide on which market to participate in and which trading strategy to follow. Traders can …

Do Institutional Investors Exploit Market Anomalies? New Evidence From Alternative Mutual Funds, Xin Gao, Ying-Chih Wang

WCBT Faculty Publications

This paper investigates the anomaly trading behavior of a sample of mutual funds mimicking hedge fund strategies, namely alternative mutual funds (AMFs), based on both of their long and short equity positions. We document that AMFs trade on anomalies by buying underpriced stocks and short-selling overpriced peers. While AMFs’ buys and sells based on their long positions do not generate superior performance, their short-selling and covering activity based on their short positions significantly negatively predicts future abnormal returns. However, this predictability is mainly attributed to size and the nine anomaly characteristics considered. Overall, the results suggest that AMFs are sophisticated …

Market Risk And Market-Implied Inflation Expectations, Lucjan T. Orlowski, Carolyne Cebrian Soper

WCBT Faculty Publications

We examine interactions between market risk and market-implied inflation expectations. We argue that these interactions are asymmetric and varied in time. Specifically, market risk becomes elevated by expectations of either very low or high expected inflation. Market risk does not react to expectations of moderate, stable inflation. In our analysis, market risk is proxied by VIX and market-implied inflation expectations are reflected by five- and ten-year breakeven inflation. We use daily data for 5 and 10 year breakeven inflation and VIX for the sample period January 3, 2003 – January 24, 2019 for empirical testing. We employ asymptotic VAR, multiple …

The Value Perspective: The Case Of Warren Buffet And His Investment Behavior Towards Apple, Walmart And Amazon, Shanhong Wu, Kermit Kuehn, Jing Jiang

WCBT Faculty Publications

In this paper, we use metrics of Ben Graham’s value investing principle to examine the actions taken by Warren Buffet toward three prominent stocks: Amazon, Apple and Walmart. We find that decisions of investment/dis-investment and not-investment by Buffet toward the stocks are largely in line with Graham’s view on value investing. This paper provides in-depth analysis of value for three stocks and relates to research on the book-to-market anomaly in the finance literature.

The Trend In Short Selling And The Cross Section Of Stock Returns, Zhaobo Zhu, Xinrui Duan, Jun Tu

Research Collection Lee Kong Chian School Of Business

This paper documents that stocks with a decreasing (increasing) trend in their short selling as proxied by the long-term change in short interest experience significant and positive (negative) abnormal returns. Moreover, the positive abnormal returns have larger absolute values and are more persistent. The return predictability of the trend in short selling is not subsumed by the level of short interest and other well-known determinants of stock returns. Investor sentiment does not affect the profitability of the trend strategy. Our results suggest that market participants underreact to public information on short interest and that short sellers are sophisticated investors.

Relative Strength Over Investment Horizons And Stock Returns, Zhaobo Zhu, Xinrui Duan, Jun Tu

Research Collection Lee Kong Chian School Of Business

In this article, the authors propose a simple and novel measure of relative strength over investment horizons that synthesizes short- and intermediate-term price information. The relative-strength measure compares the short-term price trend with the intermediate-term price trend. The relative strength strategy generates substantial profits, which are greater than a simple sum of traditional short-term reversal and momentum profits. The superior performance of the relative strength strategy is evident after risk adjustments for various factor models and is robust across subperiods and different market conditions. These findings seem consistent with investor conservatism and the idea that investors are slow to adjust …

Trust And Local Bias, Chi Shen Wei, Lei Zhang

Research Collection Lee Kong Chian School Of Business

This paper examines the effect of social trust on local bias. Our evidence suggests that institutional investors located in high-trust regions of the United States exhibit lower local bias. Moreover, we find that high-trust investors are better diversified, suggesting that trust helps accomplish greater diversification. The results are not due to firm, demographic, or local economic characteristics. Additional analysis reveals that the documented informational advantage in local holdings exists only in low-trust regions. We show that this finding is consistent with a trust explanation.
