The Role Of Accounting Information In The Sentiment-Price Relation, Kun-Chih Chen
The Role Of Accounting Information In The Sentiment-Price Relation, Kun-Chih Chen
Research Collection School Of Accountancy
This study reconciles inconsistent evidence on the sentiment-price relation in prior studies by explicitly considering the effects of sentiment on both investor judgments and risk preferences. Using the uncertainty in accounting information, I am able to disentangle these two effects of sentiment and investigate the causes of the variations in the sentiment-price relation. The results show that, under low uncertainty, the effect of sentiment on risk preferences dominates in the sentiment-price relation, such that a negative effect of sentiment on price is observed. In contrast, under high uncertainty, the effect is less negative and, in fact, becomes positive. This suggests …
International Evidence On Analyst Monitoring And Earnings Management: The Roles Of Corporate Disclosure And National Culture, Soongsoo Han, Tony Kang, Gerald Lobo, Yong Keun Yoo
International Evidence On Analyst Monitoring And Earnings Management: The Roles Of Corporate Disclosure And National Culture, Soongsoo Han, Tony Kang, Gerald Lobo, Yong Keun Yoo

We examine country-level determinants of private information search incentives, and whether analysts’ role in constraining managers’ opportunistic earnings management varies across countries. In a sample of 31,312 firm-year observations originating from 30 countries, we document that: (1) analyst coverage is negatively (positively) related to the level of corporate disclosure (how secretive the national culture is); (2) the negative association between analyst coverage and earnings management is observed in stronger investor protection countries but not in weaker investor protection countries; and (3) analyst monitoring fails to mitigate culturedriven earnings manipulations in countries with more individualistic and uncertainty-tolerant cultures. Taken together, financial …
Hedging: Scaling And The Investor Horizon, Jim Hanly, John Cotter
Hedging: Scaling And The Investor Horizon, Jim Hanly, John Cotter
Articles
This paper examines the volatility and covariance dynamics of cash and futures contracts that underlie the Optimal Hedge Ratio (OHR) across different hedging time horizons. We examine whether hedge ratios calculated over a short term hedging horizon can be scaled and successfully applied to longer term horizons. We also test the equivalence of scaled hedge ratios with those calculated directly from lower frequency data and compare them in terms of hedging effectiveness. Our findings show that the volatility and covariance dynamics may differ considerably depending on the hedging horizon and this gives rise to significant differences between short term and …
Acquisitions Driven By Stock Overvaluation, Leming Lin
Acquisitions Driven By Stock Overvaluation, Leming Lin
Dissertations and Theses Collection (Open Access)
Overvaluation might drive a firm to use its stock to acquire another firm whose stock is not as overpriced. Though hypothetically desirable, these acquisitions create little, if any, value for acquirer shareholders. Two factors impede value creation for acquirer stockholders from these transactions (despite large differences in relative overvaluation at announcement): acquirers paying large premiums to targets, and investors' correction of acquirer overvaluation during the bid period. Furthermore, acquirer CEOs obtain a large amount of new stock and option grants after acquisitions and realize a net gain in wealth, further suggesting that equity overvaluation increases agency costs and the resulting …
Does Morningstar Shine In The Universe Of Mutual Funds? A Study On Morningstar Mutual Fund Ratings, Wee Seng Ng
Does Morningstar Shine In The Universe Of Mutual Funds? A Study On Morningstar Mutual Fund Ratings, Wee Seng Ng
Dissertations and Theses Collection (Open Access)
Using data from Morningstar Principia CDs and employing standard methodologies, we examine the extent to which two mutual fund ratings: Morningstar star ratings and Morningstar stewardship grades can predict future fund performance. In particular, we investigate whether the combined predictive power of the two ratings exceeds that of a single rating. We decompose funds into various groups characterized by fund age and fund categories in order to address such issues as whether predictive performance is uniform across characteristic-based groups. Although our analysis shows that none of the ratings alone possesses strong predictive power, there is statistical evidence to support the …
Empirical Evidences On Risk-Taking And Performance Of Mutual Fund, Jingchang Lu
Empirical Evidences On Risk-Taking And Performance Of Mutual Fund, Jingchang Lu
Dissertations and Theses Collection (Open Access)
This paper examines the relationship between performance and risk exposure for mutual funds. The preliminary analysis fails to support the tournament hypothesis, which predicts that poorly performing managers will increase risk exposure while outperforming managers will decrease risk exposure. Instead, we find evidence of risk reduction for extreme losers and risk increase for winning managers. Besides, the risk-taking fails to align manager interest with shareholder interest since the returns from the risk enhancement by winners and the risk reduction by losers is relatively worse than those with contradictory strategies. Overall, the competition among fund managers appears to affect management risk …
Has The Introduction Of Bookbuilding Increased The Efficiency Of China's Ipo Pricing?, Jiehui Fei
Has The Introduction Of Bookbuilding Increased The Efficiency Of China's Ipo Pricing?, Jiehui Fei
Dissertations and Theses Collection (Open Access)
Book-building is commonly adopted in global primary markets and regarded as the most efficient pricing method for accurate IPO pricing by literatures. China has introduced book-building in 2005 to increase IPO pricing accuracy and the capabilities of domestic institutional investors. However, with the current IPO data from China, I find the level of under-pricing has unexpectedly increased after book-building, which is against the empirical studies of a few domestic papers. Secondly, there's some evidence that with better information disclosure from issuer-side through book-building process, the signaling and ex-ante uncertainty effect that previously caused under-pricing has been reduced. But there're unique …
Information Role Of Analysts' Target Prices: Event And Intra-Day Analysis, Fan Chen
Information Role Of Analysts' Target Prices: Event And Intra-Day Analysis, Fan Chen
Dissertations and Theses Collection (Open Access)
I have documented that target prices subsumed in downgrade recommendations are the most informative while target prices in coverage reiteration are the least informative. The First Call database enables me to extend the analysis to an intraday frequency. Conducting event studies using high frequency data, is even more critical given the advent of information technology systems has dramatically changed the landscape of stock trading. The modified approach to event study is relevant to the fast-changing trading environment in today's capital market. For upgrades, there are significant positive market-adjusted returns lasting 20 minutes; for downgrades, there are significant negative market-adjusted returns …
On Stock Return Patterns Following Large Weekly Price Movements: The Case Of Hong Kong, Yue Lu
On Stock Return Patterns Following Large Weekly Price Movements: The Case Of Hong Kong, Yue Lu
Dissertations and Theses Collection (Open Access)
In this paper, I examine the short-run and long-run performance of the largest 49 stocks in Hong Kong market which experience weekly price movements of more than ±10% between 1999 and 2007. For both decline and increase events, one-week significant reversal is documented. But such reversal in returns diminishes very quickly within two or three weeks. From a long-run perspective, I find that large price increases are followed by negative performance, which is consistent with the overreaction hypothesis. However, large price declines are also followed by negative cumulative abnormal returns, which supports the underreaction hypothesis. Such findings indicate that the …
The Announcement Effects And The Long-Run Performances Of Convertible Bond Issuances, Wei Xie
The Announcement Effects And The Long-Run Performances Of Convertible Bond Issuances, Wei Xie
Dissertations and Theses Collection (Open Access)
We discuss several measurements of equity components in CBs and then examine the short-run announcement effects and the long-run performances surrounding CB issuances by dividing the whole sample of CBs into a debt-like portfolio, a mixed portfolio and an equity-like portfolio. At the time of the CB issuance announcements, the market reactions to different portfolios strictly follow a hierarchy predicted by the pecking order hypothesis. In the long-run subsequent to the CB issuances, the buy and hold stock returns of the equity-like portfolio significantly underperform the industry and market benchmarks and the debt-like portfolio; the operating performances of the issuers …
The Effect Of Concentrated Institutional Portfolio On Stock Returns, Hao Li Zhang
The Effect Of Concentrated Institutional Portfolio On Stock Returns, Hao Li Zhang
Dissertations and Theses Collection (Open Access)
This paper examines whether stock return is related to the extent of portfolio concentration on the part of institutional fund managers. There is evidence that large firms are preferred for both concentrated and well-diversified funds. Also, a trading strategy based on concentrated ownership generates positive abnormal return. This implies that informational effect (implied in an increase in concentrated capital) has significant impacts and predictability on returns. Meanwhile, we do not find diversified ownership has predictability on future stock returns.
Three Sections Of Applications Of Co-Integration: Hedge Funds, Industry And Main Global Equity Markets, Zhongjian Lin
Three Sections Of Applications Of Co-Integration: Hedge Funds, Industry And Main Global Equity Markets, Zhongjian Lin
Dissertations and Theses Collection (Open Access)
Co-integration is an econometric property of time series variables. If two or more series are themselves non-stationary (unit root process), but a linear combination of them is stationary, then the series are said to be co-integrated. If there is a co-integration among some time series, we can say there is a long-run equilibrium. That is the non-stationary time series may diverge from each other in short-run, however they would arrive at equilibrium in long-run. Therefore, we can use this methodology to test the existence of commonality of some non-stationary time series. Here we apply a semi-parametric cointegration test introduced by …
Venture Capital Firm's Reputation Effect On Its Start-Up Company's Long Term Operating Performance And Survivorship, Huei Siang Yap
Venture Capital Firm's Reputation Effect On Its Start-Up Company's Long Term Operating Performance And Survivorship, Huei Siang Yap
Dissertations and Theses Collection (Open Access)
In this paper, I tested the effects of three proxies for venture capitalist(VC) reputation on its invested company's long term industry-djusted operating performances (ROA , ROE), market-to-book ratio and survival time (time to delisting) in the aftermarket. VC's market share and VC's IPO share have strong and positive association with the post-IPO long-term performance metrics, and the effects are statistically significant even after accounting for self-selection bias. For long term survivorship of start-up companies, I applied hazard analysis to the IPO company's time to delisting with accelerated failure time (AFT) model as the baseline hazard function, and found that start …
Business Aggression, Institutional Loans, And Credit Crisis: Evidence From Lending Practices In Leveraged Buyouts, Xiaping Jerry Cao, Wei-Ling Song, Joe Mason
Business Aggression, Institutional Loans, And Credit Crisis: Evidence From Lending Practices In Leveraged Buyouts, Xiaping Jerry Cao, Wei-Ling Song, Joe Mason
Research Collection Lee Kong Chian School Of Business
This paper investigates the lending practices related to leverage buyouts (LBOs) market between high and low write-down institutions. The write-downs, which are a proxy for business aggression of institutions, are mainly related to credit crisis from the beginning of 2007 to August 10, 2008. We find that high (low) write-down institutions increase (decrease) loan market share dramatically during the period of 2001-2006. The increase is mainly driven by the segment of loans sold to institutional investors, such as collateralized loan obligations vehicle, hedge fund, and insurance companies. Institutional loans originated by high write-down institutions carry significantly fewer covenants and higher …
Investor Reaction To Women Directors, E. Kang, David K. Ding, C. Charoenwong
Investor Reaction To Women Directors, E. Kang, David K. Ding, C. Charoenwong
Research Collection Lee Kong Chian School Of Business
Existing studies on women directorships present equivocal results on the association between appointing women directors and firm performance. These studies tend to focus on western countries and largely ignore investors' reactions to such appointments. This paper applies the financial event study method and finds that investors generally respond positively to the appointment of women directors in Singaporean firms. Regression analyses also reveal that investors are most receptive when the women are independent directors and are least receptive when the directors assume the CEO role. This study not only tests the theory of gender diversity in an Asian context but also …
Idiosyncratic Risk And The Cross-Section Of Expected Stock Returns, Fangjian Fu
Idiosyncratic Risk And The Cross-Section Of Expected Stock Returns, Fangjian Fu
Research Collection Lee Kong Chian School Of Business
Theories such as Merton (1987, Journal of Finance) predict a positive relation between idiosyncratic risk and expected return when investors do not diversify their portfolio. Ang, Hodrick, Xing, and Zhang (2006, Journal of Finance 61, 259-299) however find that monthly stock returns are negatively related to the one-month lagged idiosyncratic volatilities. I show that idiosyncratic volatilities are time-varying and thus their findings should not be used to imply the relation between idiosyncratic risk and expected return. Using the exponential GARCH models to estimate expected idiosyncratic volatilities, I find a significantly positive relation between the estimated conditional idiosyncratic volatilities and expected …
Designing Short Term Trading Systems With Artificial Neural Networks, Bruce Vanstone, Gavin Finnie, Tobias Hahn
Designing Short Term Trading Systems With Artificial Neural Networks, Bruce Vanstone, Gavin Finnie, Tobias Hahn
Bruce Vanstone
There is a long established history of applying Artificial Neural Networks (ANNs) to financial data sets. In this paper, the authors demonstrate the use of this methodology to develop a financially viable, short-term trading system. When developing short-term systems, the authors typically site the neural network within an already existing non-neural trading system. This paper briefly reviews an existing medium-term long-only trading system, and then works through the Vanstone and Finnie methodology to create a short-term focused ANN which will enhance this trading strategy. The initial trading strategy and the ANN enhanced trading strategy are comprehensively benchmarked both in-sample and …
