Does Herding Behavior Exist In The Cryptocurrency Market?, Anis Mnif
Does Herding Behavior Exist In The Cryptocurrency Market?, Anis Mnif
Doctoral Dissertations (DBA)
This paper examines herd behavior in the cryptocurrency market using data of the top 15 large cryptocurrencies and the CCi30 Index as a proxy for market return. The idea that investors mimic and follow the behavior of others in the cryptocurrency market rather than conducting their own research has received attention in the finance literature. The CSAD results in the static model detected herding but given the existence of structural breakdowns and nonlinearities in the data series, we opted to conduct a rolling window analysis. The results indicate strong herding behavior that fluctuates over time. Furthermore, results from the logistic …
Assessing Diversification Of S&P500 And Cdx Indexes, Jeffrey A. Palma
Assessing Diversification Of S&P500 And Cdx Indexes, Jeffrey A. Palma
Doctoral Dissertations (DBA)
In this paper, I conduct a study of comovement between equity and corporate bonds using S&P500 and Investment Grade and High Yield CDX Indexes to evaluate the diversification benefits of holding these assets in portfolios. I assess comovement and diversification potential using DCC-GARCH and copulas. This approach allows for a review of equity and credit linkages through multiple lenses and evaluation of how these relationships have evolved over time. In general, I find only modest potential for diversification between equity and CDX markets and strong evidence of increased comovement over time.
Co-Jumps, Co-Jump Tests, And Volatility Forecasting: Monte Carlo And Empirical Evidence, Weijia Peng, Chun Yao
Co-Jumps, Co-Jump Tests, And Volatility Forecasting: Monte Carlo And Empirical Evidence, Weijia Peng, Chun Yao
WCBT Faculty Publications
This study classifies jumps into idiosyncratic jumps and co-jumps to quantitatively identify systematic risk and idiosyncratic risk by utilizing high-frequency data. We found that systematic risk occurs more frequently and has larger magnitudes than the idiosyncratic risk in an individual asset, which indicates that volatilities from one sector are largely derived from the contagious effect of other sectors. We further investigated the importance of idiosyncratic jumps and co-jumps to predict the sector-level S&P500 exchange-traded fund (ETF) volatility. It was found that the predictive content of co-jumps is higher than that of idiosyncratic jumps, suggesting that systematic risk is more informative …
Kalman Filter Vs Alternative Modeling Techniques And Applied Investment Strategies, Heather E. Dempsey
Kalman Filter Vs Alternative Modeling Techniques And Applied Investment Strategies, Heather E. Dempsey
Doctoral Dissertations (DBA)
This thesis examines the efficacy of alternative modeling techniques to predict stock market returns modeled with time-varying coefficients with the goal of developing and implementing a trading strategy that yields excess returns. First, we determine the modeling technique with the smallest forecast error using historical predictors: the differenced dividend-price ratio, lagged S&P 500 returns, and the change in implied volatility. The candidate modeling techniques include both constant and recursive ordinary least squares (OLS) regression methods and diverges from previous return forecast literature with the comparison of a state-space model (SSM) cast as a VAR(1) process to each OLS technique. The …
The Value Perspective: The Case Of Warren Buffet And His Investment Behavior Towards Apple, Walmart And Amazon, Shanhong Wu, Kermit Kuehn, Jing Jiang
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.
Market Risk And Market-Implied Inflation Expectations, Lucjan T. Orlowski, Carolyne Cebrian Soper
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 …
Stock Buyback Announcements: An Examination Of Abnormal Returns In Stock Price & Credit Default Swaps For S&P100 Companies, Alan L. Delfavero
Stock Buyback Announcements: An Examination Of Abnormal Returns In Stock Price & Credit Default Swaps For S&P100 Companies, Alan L. Delfavero
Doctoral Dissertations (DBA)
This event study examines the short-run effect of stock buyback announcements on stock price and credit default swaps (CDS) exclusively for mega capitalization S&P 100 companies. The research sample consists of 53 S&P 100 companies and includes 133 buyback announcement events occurring between September 2011 and May 2018. The study utilizes the market model to estimate expected returns and to compute abnormal returns (AR) for equity and abnormal change (AC) in CDS. Based on an initial analysis, it’s determined that there is a statistically significant AR and cumulative abnormal return (CAR) for stock price, and a significant AC in CDS, …
Hedging With Volatility, Mário Alagoa
Hedging With Volatility, Mário Alagoa
Doctoral Dissertations (DBA)
A risk-averse investor with a long equity position is presumably interested in identifying a hedging strategy that protects the value of that investment. The common approach encompasses using either financial derivatives or holding assets (such as gold or Swiss francs) as portfolio hedges as they show negative correlation with equities. This paper proposes using volatility indexes as portfolio hedges instead; it shows that a volatility-based dynamic hedging strategy is the most effective at protecting the value of an equity investment.
Evaluating Volatility Forecasts In Various Equity Market Regimes, John P. Felletter
Evaluating Volatility Forecasts In Various Equity Market Regimes, John P. Felletter
Doctoral Dissertations (DBA)
Forecasting volatility is a critical component of asset allocation, risk management, and option pricing. Many different methods and models are used to predict volatility, and many studies have examined the efficacy of one method or another. This study investigates whether the abilities of historical volatility, GARCH models, and VIX to forecast volatility vary in different market conditions, as distinguished by levels of volatility and returns. It is found that market conditions do impact the abilities of the variables to forecast volatility. Overall, the forecasts implied by the GARCH models perform best according to the various metrics, while the VIX forecast …
From Pit To Electronic Trading: Impact On Price Volatility, Lucjan T. Orlowski
From Pit To Electronic Trading: Impact On Price Volatility, Lucjan T. Orlowski
WCBT Faculty Publications
This paper investigates the dynamics of price volatility and trading volume of 10-year U.S. Treasury note futures within the context of transition from pit to electronic trading. The analysis is conducted over four discernible phases of futures trading evolution: the pit-only phase, the leap to electronic trading, and the electronic trading dominant phase, which is divided further into two periods, the before and after the financial crisis of 2007/2009. Generalized autoregressive conditional heteroskedasticity with in-mean conditional variance and generalized error distribution parameterization (GARCH-M-GED) tests are conducted to examine the conditional volatility of total returns index as a function of trading …
Tracking Errors Of Exchange Traded Funds And Index Funds, Rupendra Paliwal
Tracking Errors Of Exchange Traded Funds And Index Funds, Rupendra Paliwal
WCBT Working Papers
Exchange traded funds (ETF) are one of the recent financial innovations widely viewed as significantly better investments than mutual funds given their lower fee structure and tax efficiency. Individual investors are increasingly using ETFs tracking most popular stock indices to achieve their investment goals. In some cases, investors are using these ETFs to replace index mutual funds in their long-term portfolios. Thus, it is important to compare the performance of widely held ETFs and index funds in terms of their ability to consistently track the underlying index. Another interesting research question is whether tracking errors of these two investment vehicles …
The Influence Of Director Stock Ownership And Board Discussion Transparency On Financial Reporting Quality, Jacob M. Rose, Cheri Mazza, Carolyn S. Norman, Anna M. Rose
The Influence Of Director Stock Ownership And Board Discussion Transparency On Financial Reporting Quality, Jacob M. Rose, Cheri Mazza, Carolyn S. Norman, Anna M. Rose
WCBT Faculty Publications
Seventy-two active corporate directors participate in an experiment where management insists on aggressive recognition of revenue, but the chief audit executive proposes a more conservative approach. Results indicate interactive effects of director stock ownership and the transparency of director decisions. Stock-owning directors are more likely to oppose management’s attempts to manage earnings when transparency increases. For non-stock owning directors, however, increasing transparency does not affect the likelihood that directors oppose management’s attempts to manage earnings. The current study challenges suppositions that equate director stock ownership with improved financial reporting and higher corporate governance quality, and it provides evidence that increased …
Monthly Seasonality In Emerging Market: Evidence From Bangladesh, Lutfur Rahman, Abu S. Amin
Monthly Seasonality In Emerging Market: Evidence From Bangladesh, Lutfur Rahman, Abu S. Amin
WCBT Faculty Publications
The presence of the seasonal anomaly in stock returns has been reported extensively in finance literature. This paper examines the presence of monthly anomaly in Dhaka Stock Exchange (DSE), the premier stock exchange of Bangladesh. Data used in the study include daily closing prices of DSE indices such as DSE all share prices index (DSI), DSE general index (DGEN) and DSE 20 index for a period of 01.01.2001-30.06.2010. Several hypotheses have been formulated; those hypotheses have been tested and dummy variable regression was used in the study. The result indicates that May and June returns are positive and statistically significant. …
Should Individual Investors Use Technical Trading Rules To Attempt To Beat The Market?, Thomas S. Coe, Kittipong Laosethakul
Should Individual Investors Use Technical Trading Rules To Attempt To Beat The Market?, Thomas S. Coe, Kittipong Laosethakul
WCBT Faculty Publications
Problem statement: Despite widespread academic acceptance of the Efficient Markets Hypothesis, some stock traders still use technical trading rules in an attempt to beat the market. Approach: This study looked at four trading rules, namely, the arithmetic moving average, the relative strength index, a stochastic oscillator and its moving average. These trading rules compare the relationship of current prices to past price patterns to generate a signal when to buy and sell stocks. The trading rules were tested over the years 2000-2009, a period of time that exhibited bull and bear markets, to determine if traders could actively …
