Available in PDF, EPUB and Kindle. Book excerpt: Using the monthly data for more than 1700 Australian stocks over the period from 1990 to 2009, we investigate whether industry portfolio returns predict the aggregate market. We find that a few industries significantly lead the market even controlling for well-recognized market predictors. However, unlike U.S. studies, we do not find that the ability of an industry to predict the market is closely related to its propensity to forecast economic growth. Instead, we find that the capacity of an industry to lead the market is significantly moderated by proxies for investor attention. In general, more neglected industries are more informative in leading the markets due to delayed investor attention to the information content of these industries; and the information contained in industry portfolio returns is incorporated into the market return more slowly during economic recession when investors pay less attention to the stock markets. Our research provides new empirical evidence in support of the gradual information diffusion hypothesis from a market that differs from the U.S. stock market.

Available in PDF, EPUB and Kindle. Book excerpt: There is growing literature on search behavior and using search for prediction of market share or macroeconomic indicators. This research explores investors' stock search behaviors and investigates whether there are patterns in stock returns using those for return prediction. Stock search behaviors may reveal common interest among investors. In the first study, we use graph theory to find investment habitats (or search clusters) formed by users who search common set of stocks frequently. We study stock returns of stocks within the clusters and across the clusters to provide theoretical arguments that drive returns among search clusters. In the second study, we analyze return comovement and cross-predictability among economically related stocks searched frequently by investors. As search requires a considerable amount of cognitive resources of investors, they only search a few stocks and pay high attention to them. According to attention theory, the speed of information diffusion is associated with the level of attention. Quick information diffusion allows investors to receive relevant information immediately and take instantaneous trading action. This immediate action may lead to correlated return comovement. Slow information diffusion creates latency between the occurrence of an event and the action of investors. The slower response may lead to cross-predictability. Making use of the discrepancy in information diffusion, we implement a trading strategy to establish arbitrage opportunities among stocks due to difference in user attention. This research enriches the growing IS literature on information search by (1) identifying new investment habitats based on user search behaviors, (2) showing that varying degrees of co-attention and economic linkages may lead to different speed of information diffusion (3) developing a stock forecasting model based on real-time co-attention intensity of a group economically linked stocks and (4) embarking a new research area on search attention in stock market. The methods in handling complex search data may also contribute to big data research.

This book was released on 2008-09-15 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Christian Funke aims at developing a better understanding of a central asset pricing issue: the stock price discovery process in capital markets. Using U.S. capital market data, he investigates the importance of mergers and acquisitions (M&A) for stock prices and examines economic links between customer and supplier firms. The empirical investigations document return predictability and show that capital markets are not perfectly efficient.

Book excerpt: Hou (2007) finds that within an industry, stock returns of larger firms lead those of smaller firms, suggesting an intra-industry information diffusion process. Most industry leaders, however, have business segments in other industries (henceforth, minor-segment industries), whereas most small firms are pure players operating in one industry only. If investors cannot filter out the irrelevant information from the leaders' minor segments, the pure players will be mispriced due to spurious cross-industry information diffusion (SCIID). Consistent with the SCIID hypothesis, we document both a strong contemporaneous and a lead-lag relation in stock returns between firms from industry leaders' minor-segment industries and pure players in the industry leaders' major-segment industry. Our results are not due to potential missing common factors or economic relationships between pure players and firms in the minor-segment industries.

Available in PDF, EPUB and Kindle. Book excerpt: The first paper investigates the predictive power of investors' sentiment and attention for the stock returns' volatility. We introduce a novel and extensive dataset that combines information from social media platforms, news articles, search engine data, and information consumption. Applying a state-of-the-art sentiment classification technique, we construct measures of investors' sentiment and attention for 18 U.S. stocks and the financial market in general. We identify investors' attention, as measured by the number of Google searches on financial keywords (e.g. «financial market» and «stock market»), and the daily volume of company-specific short messages posted on the social media platform StockTwits to be the most relevant variables. The second paper investigates a potential driver of the predictive power documented in the first paper. We focus on news releases of 360 U.S. companies from the S&P 500 universe and analyze how investors' attention affects the speed at which new information is incorporated in stock prices. Our results show that higher investors' attention around news releases is related to higher contemporaneous volatility. Further, retail investor attention increases the post-announcement volatility, whereas institutional investor attention has a small but negative impact on volatility on days following news releases. The third paper extends the analysis of the first paper to the multivariate stock return volatility. Building on the theoretical and empirical evidence that links the price comovements with retail investors' behavior, we analyze the predictive power of retail investors' sentiment and attention for the realized correlation matrix of 35 Dow Jones stocks. We propose a new model of realized covariances that allows exogenous predictors to influence the correlation dynamics while ensuring the predicted matrices' positive definiteness. Using this model, we find retail investors' attention to have predictive power for return correlations, especially for longer forecasting horizons and during the COVID-19 pandemic. The last paper analyzes in more detail the time-series properties of the daily online investor sentiment measures used in the first two papers. We detect structural breaks in the sentiment series for most of the 360 U.S. companies considered in this paper. We illustrate the economic significance of this finding with a return prediction exercise.

Download or read book Local Information Advantage Investor Attention and Stock Returns written by Yuqin Huang and published by . This book was released on 2016 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: We construct a measure of abnormal relative attention (ARA), reflecting unusual changes in attention paid to a stock by local relative to non-local investors, to measure local information advantages. An increase in this measure predicts higher returns in the short term. This predictive power is more prominent for local-name stocks and is robust to alternative implementations. Furthermore, long-short portfolios based on levels of ARA generate significant alphas in various risk-adjustment models. And double-sorted analysis suggests that ARA imposes a much stronger influence on firms with worse information environments.

Book excerpt: This thesis consists of three chapters that empirically investigate issues pertaining to asset pricing. In the first chapter, I find evidence of return predictability across intra-industry trading partners in international financial markets. Stock returns of importers significantly predict returns of corresponding exporters at the country-industry level. An investment strategy exploiting this effect generates average abnormal returns exceeding 6% annually. The magnitude of the effect is larger for smaller and less financially sophisticated countries, consistent with the return predictability being driven by frictions in the speed of information diffusion. However, this return cross-predictability cannot be explained by other country characteristics, including capital controls, exchange rate risk, and proxies for investor attention at the aggregate level. The second chapter analyzes the role of distance between foreign countries and the U.S. and foreign countries' talent in foreign mutual funds' performance in the U.S. I find that the correlation of distance and talent with returns is negative and positive, respectively. However, the effects are small and not statistically significant. For volatility, the effects are both economically and statistically significant: Distance is positively correlated with returns' standard deviation among mutual funds and with returns' standard deviation over time, while talent is negatively correlated with returns' standard deviation over time. The third chapter, co-authored with Jordi Mondria and Thomas Wu, decomposes attention allocation into two components, the familiar and the surprising, with opposite implications for US purchases of foreign stocks. On the one hand, familiarity-induced attention leads to an increase in US holdings of foreign equities. On the other hand, surprise-induced attention is associated with the net selling of foreign stocks because US investors tend to pay more attention to negative than to positive economic surprises from foreign countries. Our findings suggest that information asymmetries between locals and non-locals are more pronounced when it comes to good news, with information regarding bad news being relatively symmetric.

This book was released on 2020-08-28 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Artificial intelligence (AI) has grown in presence in asset management and has revolutionized the sector in many ways. It has improved portfolio management, trading, and risk management practices by increasing efficiency, accuracy, and compliance. In particular, AI techniques help construct portfolios based on more accurate risk and return forecasts and more complex constraints. Trading algorithms use AI to devise novel trading signals and execute trades with lower transaction costs. AI also improves risk modeling and forecasting by generating insights from new data sources. Finally, robo-advisors owe a large part of their success to AI techniques. Yet the use of AI can also create new risks and challenges, such as those resulting from model opacity, complexity, and reliance on data integrity.
