Available in PDF, EPUB and Kindle. Book excerpt: Investor overconfidence has been proposed to explain various anomalous findings in security markets. The theory of investor overconfidence provides testable implications assuming investor overestimation of their abilities and private information and biased self-attributions. High (low) trading activity following market gains (losses) and excessive volatility are the two testable implications among others. We test these implications in Karachi Stock Exchange, Pakistan using multivariate time series analysis. Consistent with overconfidence hypothesis predictions, we find significant positive relationship between current trading activity and past returns after controlling for returns dispersion and returns volatility. However, we do not find significant positive contribution of overconfidence related trading to conditional returns volatility.

Available in PDF, EPUB and Kindle. Book excerpt: We test the implications of overconfidence behavior using U.S. intraday trading data. We propose several testable hypotheses for return autocorrelations, trading volume, return volatility, and for the causal interrelations between volume and volatility. As predicted by overconfidence behavior, return autocorrelations are positive for short lags and then gradually decline as lags lengthen. Also consistent with the prediction of overconfidence together with biased self-attribution, return volatility is higher during periods containing public news signals compared with volatility during periods without public news signals. To differentiate between the overconfidence hypothesis and the sequential information arrival hypothesis, we test the lead-lag links between trading volume and return volatility during periods without public news. After necessary Bayesian adjustments to avoid large sample biases, we find evidence that volume Granger-causes volatility but without feedback during the periods without public news. The results lend support to the overconfidence hypothesis as opposed to the sequential information arrival hypothesis and suggest that investors trade according to their private signals but are reluctant to close their positions afterwards.
Download or read book Investor Overconfidence and Trading Volume written by Meir Statman and published by . This book was released on 2006 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: High market-wide returns make some investors overconfident because they incorrectly attribute the gains to their stock picking talents. Investors who are subject to biased self-attribution increase their trading in subsequent periods in models by Gervais and Odean (2001) and Odean (1998a). We use a vector autoregressive and impulse-response function methodology to investigate the trading volume implication of the overconfidence hypothesis. We find empirical support for the overconfidence hypothesis as well as the disposition affect of Shefrin and Statman (1985). Specifically, market-wide trading activity in NYSE/AMEX shares is positively correlated to past shocks in market return, with the turnover response lasting months and perhaps years. This increase (decrease) in market-wide trading activity subsequent to bull (bear) markets can be explained by either the overconfidence hypothesis or the disposition effect. Vector autoregressions on individual stocks indicate that volume responds to past shocks in individual security return, which prior researchers have interpreted as evidence of disposition effect trading. However, we show that individual security trading activity is even more responsive to past shocks in the market-wide return, which we interpret as evidence of the overconfidence hypothesis. The empirical lead-lag relationships between returns and trading activity as measured by turnover are both statistically and economically significant and an important empirical characteristic of the domestic equity market. The trading volume patterns we document are in addition to well-known volume-volatility relationships and turn-of-the-year effects, and are robust to a number of specification alternatives.
Download or read book Overconfidence and Trading Volume written by Markus Glaser and published by . This book was released on 2007 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theoretical models predict that overconfident investors will trade more than rational investors. We directly test this hypothesis by correlating individual overconfidence scores with several measures of trading volume of individual investors. Approximately 3,000 online broker investors were asked to answer an internet questionnaire which was designed to measure various facets of overconfidence (miscalibration, volatility estimates, better than average effect). The measures of trading volume were calculated by the trades of 215 individual investors who answered the questionnaire. We find that investors who think that they are above average in terms of investment skills or past performance (but who did not have above average performance in the past) trade more. Measures of miscalibration are, contrary to theory, unrelated to measures of trading volume. This result is striking as theoretical models that incorporate overconfident investors mainly motivate this assumption by the calibration literature and model overconfidence as underestimation of the variance of signals. In connection with other recent findings, we conclude that the usual way of motivating and modeling overconfidence which is mainly based on the calibration literature has to be treated with caution. Moreover, our way of empirically evaluating behavioral finance models - the correlation of economic and psychological variables and the combination of psychometric measures of judgment biases (such as overconfidence scores) and field data - seems to be a promising way to better understand which psychological phenomena actually drive economic behavior.

Download or read book Finance for Normal People written by Meir Statman and published by Oxford University Press. This book was released on 2017 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: Finance for Normal People teaches behavioral finance to people like you and me - normal people, neither rational nor irrational. We are consumers, savers, investors, and managers - corporate managers, money managers, financial advisers, and all other financial professionals. The book guides us to know our wants-including hope for riches, protection from poverty, caring for family, sincere social responsibility and high social status. It teaches financial facts and human behavior, including making cognitive and emotional shortcuts and avoiding cognitive and emotional errors such as overconfidence, hindsight, exaggerated fear, and unrealistic hope. And it guides us to banish ignorance, gain knowledge, and increase the ratio of smart to foolish behavior on our way to what we want. These lessons of behavioral finance draw on what we know about us-normal people-including our wants, cognition, and emotions. And they draw on the roles of these factors in saving and spending, portfolio construction, returns we can expect from our investments, and whether we can hope to beat the market. Meir Statman, a founder of behavioral finance, draws on his extensive research and the research of many others to build a unified structure of behavioral finance. Its foundation blocks include normal behavior, behavioral portfolio theory, behavioral life-cycle theory, behavioral asset pricing theory, and behavioral market efficiency.

Download or read book Volume Volatility Price and Profit When All Traders are Above Average written by Terrance Odean and published by . This book was released on 1998 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: People are overconfident. Overconfidence affects financial markets. How depends on who in the market is overconfident and on how information is distributed. This paper examines markets in which price-taking traders, a strategic-trading insider, and risk-averse market-makers are overconfident. Overconfidence increases expected trading volume, increases market depth, and decreases the expected utility of overconfident traders. Its effect on volatility and price quality depend on who is overconfident. Overconfident traders can cause markets to underreact to the information of rational traders. Markets also underreact to abstract, statistical, and highly relevant information, while they overreact to salient, anecdotal, and less relevant information.

Book excerpt: This paper presents evidence of the impact of overconfidence bias in asset prices drawn from a study based on data from tennis betting exchanges. A series of betting strategies in tournaments with a clear-cut favorite are shown to yield significant economic returns. The impact of overconfidence bias on betting odds increases with levels of disagreement, trading volume and media coverage. Just as in traditional financial markets, arbitrage limits are shown to be a necessary condition for the impact of behavioral biases on prices.

Book excerpt: Bank Liquidity Creation and Financial Crises delivers a consistent, logical presentation of bank liquidity creation and addresses questions of research and policy interest that can be easily understood by readers with no advanced or specialized industry knowledge. Authors Allen Berger and Christa Bouwman examine ways to measure bank liquidity creation, how much liquidity banks create in different countries, the effects of monetary policy (including interest rate policy, lender of last resort, and quantitative easing), the effects of capital, the effects of regulatory interventions, the effects of bailouts, and much more. They also analyze bank liquidity creation in the US over the past three decades during both normal times and financial crises.

Explains that bank liquidity creation is a more comprehensive measure of a bank’s output than traditional measures and can also be used to measure bank liquidity Describes how high levels of bank liquidity creation may cause or predict future financial crises Addresses questions of research and policy interest related to bank liquidity creation around the world and provides links to websites with data and other materials to address these questions Includes such hot-button topics as the effects of monetary policy (including interest rate policy, lender of last resort, and quantitative easing), the effects of capital, the effects of regulatory interventions, and the effects of bailouts
Download or read book Disposition Matters written by Massimo Massa and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, we estimate the behavioral component of the Grinblatt and Han (2002) model and derive several testable implications about the expected relationship between the preponderance of disposition - prone investors in a market and volume, volatility and stock returns. To do this, we use a large sample of individual accounts over a six-year period in the 1990's in order to identify investors who are subject to the disposition effect. We then use their trading behavior to construct behavioral factors. We show that when the fraction of quot;irrationalquot; investor purchases in a stock increases, the unexplained portion of the market price of the stock decreases. We further show that statistical exposure to a disposition factor explains cross-sectional differences in daily returns, controlling for a host of other factors and characteristics. The evidence is consistent with the hypothesis that trade between disposition-prone investors and their counter-parties impact relative prices.
Download or read book Speculation Trading and Bubbles written by José A. Scheinkman and published by Columbia University Press. This book was released on 2014-07-08 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: As long as there have been financial markets, there have been bubbles—those moments in which asset prices inflate far beyond their intrinsic value, often with ruinous results. Yet economists are slow to agree on the underlying forces behind these events. In this book José A. Scheinkman offers new insight into the mystery of bubbles. Noting some general characteristics of bubbles—such as the rise in trading volume and the coincidence between increases in supply and bubble implosions—Scheinkman offers a model, based on differences in beliefs among investors, that explains these observations. Other top economists also offer their own thoughts on the issue: Sanford J. Grossman and Patrick Bolton expand on Scheinkman's discussion by looking at factors that contribute to bubbles—such as excessive leverage, overconfidence, mania, and panic in speculative markets—and Kenneth J. Arrow and Joseph E. Stiglitz contextualize Scheinkman's findings.
Download or read book Inefficient Markets written by Andrei Shleifer and published by OUP Oxford. This book was released on 2000-03-09 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: The efficient markets hypothesis has been the central proposition in finance for nearly thirty years. It states that securities prices in financial markets must equal fundamental values, either because all investors are rational or because arbitrage eliminates pricing anomalies. This book describes an alternative approach to the study of financial markets: behavioral finance. This approach starts with an observation that the assumptions of investor rationality and perfect arbitrage are overwhelmingly contradicted by both psychological and institutional evidence. In actual financial markets, less than fully rational investors trade against arbitrageurs whose resources are limited by risk aversion, short horizons, and agency problems. The book presents and empirically evaluates models of such inefficient markets. Behavioral finance models both explain the available financial data better than does the efficient markets hypothesis and generate new empirical predictions. These models can account for such anomalies as the superior performance of value stocks, the closed end fund puzzle, the high returns on stocks included in market indices, the persistence of stock price bubbles, and even the collapse of several well-known hedge funds in 1998. By summarizing and expanding the research in behavioral finance, the book builds a new theoretical and empirical foundation for the economic analysis of real-world markets.
