Stock Market Manipulation Detection Using Continuous Wavelet Transform & Machine Learning Classification, 2021 American University in Cairo
Stock Market Manipulation Detection Using Continuous Wavelet Transform & Machine Learning Classification, Sarah Youssef
Theses and Dissertations
Stock market manipulation detection is important for both investors and regulators. Being able to detect stock manipulation and preventing it gives investors the confidence in the market fairness and integrity. It also helps maintaining liquidity of the stocks and market efficiency. Implementing data mining algorithms in manipulation detection is a relatively recent technique but in the past few years there has been an increasing interest in it's applications in this domain. The benefit of monitoring manipulative trade behavior is that it can be implemented on live feed of stock data, which saves a lot of time in detecting stock ...
Hedge Funds And Their Prime Broker Analysts, 2021 Wayne State University
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 ...
Capital Allocation Imbalance And The Effects On Monetary Policy, 2021 Sacred Heart University
Capital Allocation Imbalance And The Effects On Monetary Policy, Peter G. George
Doctoral Dissertations (DBA)
This paper examines the association between liquidity injections and capital allocations in the United States. In the analysis, liquidity injections are proxied by monetary base and the capital allocations are reflected by excess reserves, vault cash, total bank credit, and M2-M1. Monthly data are utilized for all variables for the sample period March 1984 – June 2020. Four Bai-Perron multiple breakpoint regressions and Markov switching estimations are employed to examine changeable patterns and interactions. The results indicate that liquidity injections are imbalanced and are allocated to total bank credit prior to quantitative easing, excess reserves prior to QE through post-QE, vault ...
How The Growth Of Technology Has Forced Accounting Firms To Put An Emphasis On Cybersecurity, 2021 University of Arkansas, Fayetteville
How The Growth Of Technology Has Forced Accounting Firms To Put An Emphasis On Cybersecurity, Holden Halbach
Accounting Undergraduate Honors Theses
The advancement of technology has brought many changes to accounting firms. Computer applications such as Microsoft Excel have made calculators and physical spreadsheets obsolete. Then with the introduction of cloud computing employees can store, access, and exchange large amounts of data instantaneously from any location. These technological innovations have increased the accuracy and efficiency of firms substantially. However, this growth in technology has shown the importance of putting an emphasis on cybersecurity throughout the accounting industry. The emphasis placed on cybersecurity throughout accounting firms is more prevalent than any other industry. This is primarily because accounting firms not only deal ...

Short Selling Around Reverse Stock Splits, 2021 Utah State University
Short Selling Around Reverse Stock Splits, Ryan Voges
All Graduate Plan B and other Reports
I examine whether short selling increases around reverse stock splits using 2019 daily short selling data instead of bimonthly short interest data required by FINRA. In my difference-in-difference analysis, I find that average short selling increases significantly for firms that reverse split their stock, relative to matched control firms that do not, around the split dates. I also find that firms that reverse split their stock experience negative cumulative abnormal returns in the 20-day period after the reverse stock splits, particularly for those firms that are heavily shorted. These results are in agreeance with existent literature and suggest that short ...
Global Recognition Of Sustainable Companies And The Search For Meaningful Returns, 2021 Sacred Heart University
Global Recognition Of Sustainable Companies And The Search For Meaningful Returns, Jenny Gyurova Hite
Doctoral Dissertations (DBA)
Can an investor realize meaningful returns by choosing sustainability? Global Knights publishes an annual 100 Global Most Sustainable companies list which has been announced each January in Davos, Switzerland since 2005. This paper examines the global recognition of the US sustainable companies which make that list and the presence of cumulative abnormal returns of their portfolio. Event study methodology is used to assess short and long term cumulative abnormal returns of a dynamic portfolio updated annually over 16 years to include those names. Standard Deviations and Sortino Ratios are evaluated to determine the comparative level of risk a potential investor ...
Do Students Buy Attention-Grabbing Stocks? A Field Experiment, 2021 Ursinus College
Do Students Buy Attention-Grabbing Stocks? A Field Experiment, George Psaradakis
Business and Economics Honors Papers
In this paper, we look to find out whether or not student investors are drawn to “attention-grabbing” stocks. We define “attention-grabbing” stocks as those that are issued by companies with either large numbers of Twitter followers, large general marketing budgets, or both. Our theory is that the more followers that a publicly traded company has on Twitter and/or the more money the company spends on marketing and advertising, the more likely a student would be to invest in its stock.
A field experiment was conducted in which undergraduate students constructed their own virtual stock portfolios. A treatment group was ...
The U.S. Presidential Election Cycle And Stock Market Returns, 2021 Sacred Heart University
The U.S. Presidential Election Cycle And Stock Market Returns, Georginus Ejiofor Ugwu
Doctoral Dissertations (DBA)
This paper analyzes the relationship between the presidential election year and the stock market returns in the United States by examining the monthly returns of the Standard &Poor’s 500 stock index from January 1959 to December 2019. In essence, I test whether stock market returns improve during presidential election year, consistent with the political business cycle (PBC) and its later offshoot, the ‘presidential election cycle (PEC) hypothesis, which assumes that incumbent presidents and their parties improve economic growth and the stock market outlook by embracing expansionary macroeconomic policy. I employ the Least Squares Regression tests on monthly S&P ...
Do Esg Mutual Funds Deliver On Their Promises?, 2021 University of Virginia
Do Esg Mutual Funds Deliver On Their Promises?, Quinn Curtis, Jill E. Fisch, Adriana Z. Robertson
Faculty Scholarship at Penn Law
Corporations have received growing criticism for their role in climate change, perpetuating racial and gender inequality, and other pressing social issues. In response to these concerns, shareholders are increasingly focusing on environmental, social, and corporate governance (ESG) criteria in selecting investments, and asset managers are responding by offering a growing number of ESG mutual funds. The flow of assets into ESG is one of the most dramatic trends in asset management.
But are these funds giving investors what they promise? This question has attracted the attention of regulators, with the Department of Labor and the Securities and Exchange Commission (SEC ...

Dispelling The Hype: An Examination Of Spac Common Equity Performance, 2021 California Polytechnic State University, San Luis Obispo
Dispelling The Hype: An Examination Of Spac Common Equity Performance, Lauren Helen Chamberlain
The U.S. SPAC market has faced explosive growth in recent years, but the financial performance of these investments is weakly understood. Therefore, this paper contributes an analysis on the long-term performance of SPAC common equity for SPACs that completed acquisitions between 2016 and 2018. Using hand-collected data from the Compustat – Capital IQ and SEC EDGAR databases, this paper runs a two-sample t-test assuming unequal variances and constructs an Ordinary Least Squares (OLS) regression model. In conclusion of the t-test, the results suggest that SPAC common shares do not outperform the market over a three-year holding period. In addition, the ...
Twitter’S Relationship With Overreaction In Individual Security Returns, 2021 Claremont Colleges
Twitter’S Relationship With Overreaction In Individual Security Returns, David Halle
CMC Senior Theses
Using stock market return data from 2007 to 2019 from The Center for Research in Security Prices, I inquire into the impact that Twitter has on the overreactions of individual stock returns by breaking down returns into pre and post-Twitter periods. I examine negative serial correlation, demonstrating return reversals, between a lag crossed Twitter dummy variable and initial returns. With stock reversals serving as an indicator of initial overreaction and assuming stationarity of overreactions over time, I find that the presence of Twitter results in significantly more overreactions for highly followed companies when using monthly returns. However, when assessing Twitter ...
What Is The Riskfree Rate? A Search For The Basic Building Block, 2020 New York University - Stern School of Business
What Is The Riskfree Rate? A Search For The Basic Building Block, Aswath Damodaran
Journal of New Finance
In corporate finance and valuation, we start off with the presumption that the riskfree rate is given and easy to obtain and focus the bulk of our attention on estimating the risk parameters of individuals firms and risk premiums. But is the riskfree rate that simple to obtain? Both academics and practitioners have long used government security rates as riskfree rates, though there have been differences on whether to use short term or long- term rates. In this paper, we not only provide a framework for deciding whether to use short or long term rates in analysis but also a ...
Diversification Using International Exchange-Traded Funds, 2020 The University of Southern Mississippi
Diversification Using International Exchange-Traded Funds, Alese K. Jones
Exchange-Traded Funds (ETFs) are diversified portfolios of assets which trade like stocks and track a benchmark index. This manuscript looks at the diversification and return benefits a U.S. investor would receive by investing in Emerging market (EEM) and Total World (DGT) ETFs over the period of June 2003 to July 2019. We use S&P 500 ETF IVV as a proxy for U.S. market. EEM had the highest absolute return but also the highest risk. However, the U.S. ETF IVV had the greatest risk-adjusted return and the lowest tracking error. International ETFs were also highly correlated with ...
Behavioral Finance For The Individual Investor, 2020 Liberty University
Behavioral Finance For The Individual Investor, Drake Gens
Senior Honors Theses
The Efficient Market Hypothesis (EMH) has been generally accepted in academia despite its well-researched flaws; by understanding how and when markets deviate from efficiency, investors have an opportunity to not only better understand their investing habits, but also possibly generate higher investment returns. Various market anomalies, such as the Value Effect (De Bondt & Thaler, 1985), the Monday Effect (French, 1980), and the January Effect (De Bondt and Thaler, 1958 & 1987), attest to the fact that markets experience periods of deviation from efficiency. Fiévet and Sornette (2016) finding that markets experience inefficiency during periods of significant volatility is confirmed by behavioral finance, which explains how behavioral heuristics influence investment decisions, specifically greed and fear (p.38). Andrew Lo based his substitute for the EMH, the Adaptive Market Hypothesis (AMH), on the supposition that markets become inefficient because of irrational investor behavior (Urquhart & McGroarty, 2016). In applying these concepts to an individual’s portfolio, it could provide great insight into their own trading patterns; for investors with higher risk tolerance, these theories could help produce larger returns for their investment portfolios.
Is The Synthetic Stock Price Really Lower Than Actual Price?, 2020 Singapore Management University
Is The Synthetic Stock Price Really Lower Than Actual Price?, Jianfeng Hu
Research Collection Lee Kong Chian School Of Business
Conventional wisdom suggests synthetic stock prices are lower than actual prices due to short‐sale constraints and voting premiums. This study finds that such underpricing of the synthetic midquote disappears if arbitrageurs face security borrowing costs. The synthetic spread predominantly contains the actual spread. Synthetic stock overpricing is as common as underpricing but the former is more persistent and more profitable. The difference between synthetic and actual quotes is significantly affected by options market makers' hedging costs and investors' demand for leverage.
Investor Behavior In The Midst Of A Global Pandemic, 2020 Grand Valley State University
Investor Behavior In The Midst Of A Global Pandemic, Abigail N. Bates
Investors partaking in portfolio and asset management through the stock market and other avenues do so with certain reasoning and methods in hand. Each investor may have different interests and risk tolerances that guide their choices for investment. Behavioral finance allows for an in-depth look at an investor’s actions and the influencing psychology behind it. Before this approach was popularized, early studies of finance assumed that investors were always rational in their decision making and put resources only into opportunities that would increase their utility or happiness. The behavioral finance approach takes a more comprehensive look at these behaviors ...
What Do Short Sellers Know?, 2020 Singapore Management University
What Do Short Sellers Know?, Ekkehart Boehmer, Charles M. Jones, Juan (Julie) Wu, Xiaoyan Zhang
Research Collection Lee Kong Chian School Of Business
Using NYSE short-sale order data, we investigate whether short sellers' informational advantage is related to firm earnings and analyst-related events. With a novel decomposition method, we find that while these fundamental event days constitute only 12% of sample days, they account for over 24% of the overall underperformance of heavily shorted stocks. Importantly, short sellers use both public news and private information to anticipate news regarding earnings and analysts. Shorting's predictive ability remains significant after controlling for information in analyst actions and displays no reversal patterns, indicating that short sellers know more than analysts, and the nature of their ...
