On The Effects Of Information Asymmetry In Digital Currency Trading, Kwansoo Kim, Robert John Kauffman Mar 2024

On The Effects Of Information Asymmetry In Digital Currency Trading, Kwansoo Kim, Robert John Kauffman

Research Collection School Of Computing and Information Systems

We report on two studies that examine how social sentiment influences information asymmetry in digital currency markets. We also assess whether cryptocurrency can be an investment vehicle, as opposed to only an instrument for asset speculation. Using a dataset on transactions from an exchange in South Korea and sentiment from Korean social media in 2018, we conducted a study of different trading behavior under two cryptocurrency trading market microstructures: a bid-ask spread dealer's market and a continuous trading buy-sell, immediate trade execution market. Our results highlight the impacts of positive and negative trader social sentiment valences on the effects of …


Who Profits From Trading Options?, Jianfeng Hu, Antonia Kirilova, Gilbert Seongkyu Park, Doojin. Ryu Sep 2023

Who Profits From Trading Options?, Jianfeng Hu, Antonia Kirilova, Gilbert Seongkyu Park, Doojin. Ryu

Research Collection Lee Kong Chian School Of Business

We use account-level transaction data to examine trading styles and profitability in a leading derivatives market. Approximately 66% of active retail investors predominantly hold simple, one-sided positions in only one class of options, whereas institutional investors are more likely to use complex strategies. Hypothesizing that the complexity of trading styles reflects investors' skills, we examine the effect of options trading styles on investment performance. We find that retail investors using simple strategies lose to the rest of the market. For both retail and institutional investors, selling volatility is the most successful strategy. We conclude that these style effects are persistent …


Accounting Scandals And Implications For Directors: Lessons From Enron, Pearl Hock-Neo Tan, Gillian Yeo Aug 2022

Accounting Scandals And Implications For Directors: Lessons From Enron, Pearl Hock-Neo Tan, Gillian Yeo

Research Collection School Of Accountancy

We analyze the Enron case to identify the risk factors that potentially led to its collapse and specific issues relating to its aggressive accounting and high-light the lessons for independent directors. In Enron, the interactions between external stimuli, strategies, corporate culture, and risk exposures possibly created an explosive situation that eventually led to its demise. Much of the post-Enron reforms have been directed towards regulating the roles and responsibilities of executive directors and auditors. However, the role of independent directors has received relatively lesser attention. Independent directors should analyze the risks of their companies and understand the pressures that arise …


Decentralizing Money: Bitcoin Prices And Blockchain Security, Emiliano Sebastian Pagnotta Feb 2022

Decentralizing Money: Bitcoin Prices And Blockchain Security, Emiliano Sebastian Pagnotta

Research Collection Lee Kong Chian School Of Business

We address the determination of bitcoin prices and decentralized security. Users forecast the transactional and resale values of holdings, pricing the risk of systemic attacks. Miners contribute resources to protect against attackers and compete for block rewards. Bitcoin's design leads to multiple equilibria: the same blockchain technology is consistent with sharply different price and security levels. Bitcoin's monetary policy can lead to welfare losses and deviations from quantity theory. Price-security feedback amplifies fundamental shocks' volatility impact and leads to boom and busts unconnected to fundamentals. We characterize how viability versus fiat currency depends on bitcoin's relative acceptability and inflation protection.


Rise Of The Machines? Intraday High-Frequency Trading Patterns Of Cryptocurrencies, Alla A Petukhina, Raphael C. G. Reule, Wolfgang Karl Hardle Jan 2021

Rise Of The Machines? Intraday High-Frequency Trading Patterns Of Cryptocurrencies, Alla A Petukhina, Raphael C. G. Reule, Wolfgang Karl Hardle

Sim Kee Boon Institute for Financial Economics

This research analyses high-frequency data of the cryptocurrency market in regards to intraday trading patterns related to algorithmic trading and its impact on the European cryptocurrency market. We study trading quantitatives such as returns, traded volumes, volatility periodicity, and provide summary statistics of return correlations to CRIX (CRyptocurrency IndeX), as well as respective overall high-frequency based market statistics with respect to temporal aspects. Our results provide mandatory insight into a market, where the grand scale employment of automated trading algorithms and the extremely rapid execution of trades might seem to be a standard based on media reports. Our findings on …


Risk Premium Spillovers Among Stock Markets: Evidence From Higher-Order Moments, Marinela Adriana Finta, Sofiane Aboura Jun 2020

Risk Premium Spillovers Among Stock Markets: Evidence From Higher-Order Moments, Marinela Adriana Finta, Sofiane Aboura

Research Collection Lee Kong Chian School Of Business

We investigate the volatility and skewness risk premium spillovers among the U.S., U.K., German, and Japanese stock markets. We define risk premia as the difference between risk-neutral and realized moments. Our findings highlight that during periods of stress, cross-market and cross-moment spillovers increase and that these increases are mirrored by a decrease in within-market effects. We document strong bidirectional spillovers between volatility and skewness risk premia and emphasize the prominent role played by the volatility risk premium. Finally, we show that several announcements drive the time-varying risk premium spillovers.


Understanding Cryptocurrencies, Wolfgang Karl Hardle, Campbell R. Harvey, Raphael C. G. Ruele Mar 2020

Understanding Cryptocurrencies, Wolfgang Karl Hardle, Campbell R. Harvey, Raphael C. G. Ruele

Sim Kee Boon Institute for Financial Economics

Cryptocurrency refers to a type of digital asset that uses distributed ledger, or blockchain, technology to enable a secure transaction. Although the technology is widely misunderstood, many central banks are considering launching their own national cryptocurrency. In contrast to most data in financial economics, detailed data on the history of every transaction in the cryptocurrency complex are freely available. Furthermore, empirically oriented research is only now beginning, presenting an extraordinary research opportunity for academia. We provide some insights into the mechanics of cryptocurrencies, describing summary statistics and focusing on potential future research avenues in financial economics.


Chasing Private Information, Marcin Kacperczyk, Emiliano Sebastian Pagnotta Dec 2019

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.

Situatedbetween the companies are in the business of taking risks for rewards. Situatedbetween the companies and the rewards are risks. Critical concepts in thisprocess are volatility, uncertainty, complexity, and ambiguity (VUCA), a trendymanagerial acronym that conflates the reality of the business environment and the challenges ofrisk management.


The Effectiveness Of Trading Halts And Investor Trading Performance, Nareerat Taechapiroontong, Charlie Charoenwong, Chiyachantana N. Chiraphol, Radchda Lurang Dec 2012

The Effectiveness Of Trading Halts And Investor Trading Performance, Nareerat Taechapiroontong, Charlie Charoenwong, Chiyachantana N. Chiraphol, Radchda Lurang

Research Collection Lee Kong Chian School Of Business

This paper examines the effectiveness of trading halts and the trading performance of different types of investors or traders during halts in an Asian emerging equity market. We use trade-by-trade data flagged by types of traders between January 1999 and December 2007. The results suggest that trading halts improve the efficiency of the market by reducing the information asymmetry and stabilizing the market. Trading halts serve as devices to facilitate a price discovery process by giving investors opportunity to adjust their trading interests and reaction to the material information. Our findings show that return and volatility tend to revert to …


Hedge Funds In A Volatile Market, Melvyn Teo Jul 2008

Hedge Funds In A Volatile Market, Melvyn Teo

Research Collection BNP Paribas Hedge Fund Centre

We show that relative to the first half of 2007, the volatility of hedge fund returns has doubled during the September 2007 to April 2008 period. At the same time, aggregate hedge fund returns have declined while exit rates have tripled. Commodity, macro, and, to a lesser extent, arbitrage funds outperformed during this period, while bottom-up funds underperformed. In Asia, funds engaging in less traditional strategies like arbitrage, event driven, fixed income, and distressed debt have emerged relatively unscathed. Our results also suggest that around the world, funds with headquarters near their investment markets, fewer assets under management, and higher …


Test For Infinite Variance In Stock Returns, Xian Ning Yan Jan 2008

Test For Infinite Variance In Stock Returns, Xian Ning Yan

Dissertations and Theses Collection (Open Access)

The existence of second order moment or the finite variance is a commonly used assumption in financial time series analysis. We examine the validation of this condition for main stock index return series by applying the extreme value theory. We compare the performances of the adaptive Hill's estimator and the Smith's estimator for the tail index using Monte Carlo simulations for both i.i.d data and dependent data. The simulation results show that the Hill's estimator with adaptive data-based truncation number performs better in both cases. It has not only smaller bias but also smaller MSE when the true tail index …


The Impact Of Regulation Fair Disclosure On Information Asymmetry And Trading: An Intraday Analysis, Chiraphol N. Chiyachantana, Christine X. Jiang, Nareerat Taechapiroontong, Robert A. Wood Nov 2004

The Impact Of Regulation Fair Disclosure On Information Asymmetry And Trading: An Intraday Analysis, Chiraphol N. Chiyachantana, Christine X. Jiang, Nareerat Taechapiroontong, Robert A. Wood

Research Collection Lee Kong Chian School Of Business

This study examines the impact of Regulation Fair Disclosure (FD) on liquidity, information asymmetry, and institutional and retail investors trading behavior. Our main findings suggest three conclusions. First, Regulation FD has been effective in improving liquidity and in decreasing the level of information asymmetry. Second, retail trading activity increases dramatically after earnings announcements but there is a significant decline in institutional trading surrounding earnings announcements, particularly in the pre‐announcement period. Last, the decline in information asymmetry around earnings announcements is closely associated with a lower participation rate in the pre‐announcement period and more active trading of retail investors after earnings …


The Contribution Of A Satellite Market To Price Discovery: Evidence From The Singapore Exchange, Vicentiu Covrig, David K. Ding, Buen Sin Low Oct 2004

The Contribution Of A Satellite Market To Price Discovery: Evidence From The Singapore Exchange, Vicentiu Covrig, David K. Ding, Buen Sin Low

Research Collection Lee Kong Chian School Of Business

The Singapore Exchange (SGX), a small satellite market, successfully competes with a large home market, the Osaka Securities Exchange (OSE), in trading the Nikkei 225 futures index. In this paper, we investigate the contribution of the SGX to price discovery and shed light on the reasons for its continued success. Evidence is provided from information revelation and price discovery of three competing but informationally linked markets of the Nikkei 225 index - domestic spot (Tokyo Stock Exchange), domestic futures (OSE), and foreign futures (SGX), which represents the satellite market. Overall, the futures market contributes 77% to price discovery, with the …
