Book excerpt: This paper studies the ICAPM intertemporal relation between the conditional mean and the conditional variance of the aggregate stock market return. We introduce a new estimator that forecasts monthly variance with past daily squared returns %u2013 the Mixed Data Sampling (or MIDAS) approach. Using MIDAS, we find that there is a significantly positive relation between risk and return in the stock market. This finding is robust in subsamples, to asymmetric specifications of the variance process, and to controlling for variables associated with the business cycle. We compare the MIDAS results with tests of the ICAPM based on alternative conditional variance specifications and explain the conflicting results in the literature. Finally, we offer new insights about the dynamics of conditional variance.

This book was released on 2014 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: We examine the prediction of Merton's intertemporal CAPM that time varying risk premiums arise from the conditional covariances of returns on assets with the return on the market and other state variables. We find a positive and significant price of risk for the covariance with the market return that is driven by the time series variation in the conditional covariances, and the risk-premium on the market remains positive and significant after controlling for additional state variables. Our method estimates the risk-return tradeoff in the ICAPM using multiple portfolios as test assets.

This book was released on 2006-09-28 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book criticizes the fact that profitability measures derived from capital market models such as the Sharpe ratio and the reward-to-VaR ratio are proposed for loan portfolios, although it is not proven whether their risk-return trade-offs are optimal for banks. The authors demonstrate that even the reward-to-VaR ratio, which is developed for valuating loan portfolios, can be highly misleading. They also show how market discipline, capital requirements, and insured deposits affect decision-making.

Download or read book Plight of the Fortune Tellers written by Riccardo Rebonato and published by Princeton University Press. This book was released on 2007-09-17 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today's top financial-risk professionals have come to rely on ever-more sophisticated mathematics in their attempts to come to grips with financial risk. But this excessive reliance on quantitative precision is misleading--and it puts us all at risk. This is the case that Riccardo Rebonato makes in Plight of the Fortune Tellers--and coming from someone who is both an experienced market professional and an academic, this heresy is worth listening to. Rebonato forcefully argues that we must restore genuine decision making to our financial planning, and he shows us how to do it using probability, experimental psychology, and decision theory. This is the only way to effectively manage financial risk in a manner congruent with how human beings actually react to chance. Rebonato challenges us to rethink the standard wisdom about probability in financial-risk management. Risk managers have become obsessed with measuring risk and believe that these quantitative results by themselves can guide sound financial choices--but they can't. In this book, Rebonato offers a radical yet surprisingly commonsense solution, one that seeks to remind us that managing risk comes down to real people making decisions under uncertainty. Plight of the Fortune Tellers is not only a book for the decision makers of Wall Street, it's a must-read for anyone concerned about how today's financial markets are run. The stakes have never been higher--can you risk it?
Download or read book Risk and Return for Regulated Industries written by Bente Villadsen and published by Academic Press. This book was released on 2017-04-27 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk and Return for Regulated Industries provides a much-needed, comprehensive review of how cost of capital risk arises and can be measured, how the special risks regulated industries face affect fair return, and the challenges that regulated industries are likely to face in the future. Rather than following the trend of broad industry introductions or textbook style reviews of utility finance, it covers the topics of most interest to regulators, regulated companies, regulatory lawyers, and rate-of-return analysts in all countries. Accordingly, the book also includes case studies about various countries and discussions of the lessons international regulatory procedures can offer. Presents a unified treatment of the regulatory principles and practices used to assess the required return on capital Addresses current practices before exploring the ways methods play out in practice, including irregularities, shortcomings, and concerns for the future Focuses on developed economies instead of providing a comprehensive global reviews Foreword by Stewart C.

Download or read book Is There a Risk Return Tradeoff Evidence from High Frequency Data written by Turan G. Bali and published by . This book was released on 2012 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper examines the intertemporal relation between risk and return for the aggregate stock market using high-frequency data. We use daily realized, GARCH, implied, and range-based volatility estimators to determine the existence and significance of a risk-return tradeoff for several stock market indices. We find a positive and statistically significant relation between the conditional mean and conditional volatility of market returns at the daily level. This result is robust to alternative specifications of the volatility process, across different measures of market return and sample periods, and after controlling for macroeconomic variables associated with business cycle fluctuations. We also analyze the risk-return relationship over time using rolling regressions, and find that the strong positive relation persists throughout our sample period. The market risk measures adopted in the paper add power to the analysis by incorporating valuable information, either by taking advantage of high frequency intraday data (in the case of realized, GARCH, and range volatility) or by utilizing the market's expectation of future volatility (in the case of implied volatility index).
Download or read book Safe Haven written by Mark Spitznagel and published by John Wiley & Sons. This book was released on 2023-10-10 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is a safe haven? What role should they play in an investment portfolio? Do we use them only to seek shelter until the passing of financial storms? Or are they something more? Contrary to everything we know from modern financial theory, can higher returns actually come as a result of lowering risk? In Safe Haven, hedge fund manager Mark Spitznagel—one of the top practitioners of safe haven investing and portfolio risk mitigation in the world—answers these questions and more. Investors who heed the message in this book will never look at risk mitigation the same way again.
Download or read book The Term Structure of the Risk return Tradeoff written by John Y. Campbell and published by . This book was released on 2005 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent research in empirical finance has documented that expected excess returns on bonds and stocks, real interest rates, and risk shift over time in predictable ways. Furthermore, these shifts tend to persist over long periods of time. In this paper we propose an empirical model that is able to capture these complex dynamics, yet is simple to apply in practice, and we explore its implications for asset allocation. Changes in investment opportunities can alter the risk-return tradeoff of bonds, stocks, and cash across investment horizons, thus creating a term structure of the risk-return tradeoff.'' We show how to extract this term structure from our parsimonious model of return dynamics, and illustrate our approach using data from the U.S. stock and bond markets. We find that asset return predictability has important effects on the variance and correlation structure of returns on stocks, bonds and T-bills across investment horizons
Download or read book The Risk Return Tradeoff in the Long Run written by Christian T. Lundblad and published by . This book was released on 2012 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: The risk-return tradeoff is fundamental to finance. However, while many asset pricing models imply a positive relationship between the risk premium on the market portfolio and the variance of its return, previous studies find the empirical relationship is weak at best. In sharp contrast, this study, demonstrates that the weak empirical relationship is an artifact of the small sample nature of the available data, as an extremely large number of time-series observations is required to precisely estimate this relationship. To maximize the available time-series, I employ the nearly two century history of US equity market returns from Schwert (1990), exploring the empirical risk-return tradeoff for a variety of specifications that allow for asymmetric volatility, regime-switching, and additional factors associated with intertemporal (ICAPM) hedging demands. Similar to studies that use the more recent US equity price history, conditional market volatility in the historical data is persistent and displays strong asymmetric relationships to return innovations. Further, the conditional correlation between stock and bond markets is closely related to periods of documented financial crises. Finally, in contrast to evidence based upon the recent US experience, the estimated relationship between risk and return is positive and statistically significant across every specification considered.

Available in PDF, EPUB and Kindle. Book excerpt: A timeless classic of economic theory that remains fascinating and pertinent today, this is Frank Knight's famous explanation of why perfect competition cannot eliminate profits, the important differences between "risk" and "uncertainty," and the vital role of the entrepreneur in profitmaking. Based on Knight's PhD dissertation, this 1921 work, balancing theory with fact to come to stunning insights, is a distinct pleasure to read. FRANK H. KNIGHT (1885-1972) is considered by some the greatest American scholar of economics of the 20th century. An economics professor at the University of Chicago from 1927 until 1955, he was one of the founders of the Chicago school of economics, which influenced Milton Friedman and George Stigler.
Download or read book Market States and the Risk Return Tradeoff written by Zijun Wang and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We re-examine the risk-return trade off in U.S. equity market by allowing for time variation in the tradeoff and estimating the conditional variance by the new mixed data sampling method. The main finding is that the risk-return tradeoff is strongly time-varying with the state of the market and the average of the time-varying tradeoff is 1.43. The lagged market return is found to be the best indicator of market states. The empirical finding holds true for a battery of robustness checks during the post-Compustat sample period. The evidence from the international markets is similar to the U.S. one.

Download or read book The Risk Return Trade Off written by Enrico Rubaltelli and published by . This book was released on 2009 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditional economic models state that riskier investments should have a higher expected return. Psychological models of choice showed that people is influenced by the kind of information they are provided with and by the context of the choice, since they do not have a stable order of preferences but, rather, they construct it while giving a judgment. Experiment 1 showed that people consider the expected return of an equity only when it is explicitly stated, rather than computing it on the basis of the expected outcomes and probabilities. Experiment 2 and 3 showed that people judgments about the expected return of a stock are influenced by the way they are required to provide their estimates. In Experiment 2 participants' judgments were inconsistent with the risk-return trade off, whereas in Experiment 3 people asked a higher return from a riskier stock than from a safer one. Implications of the results for investors' behavior are discussed.
Download or read book Asset Pricing and the Intertemporal Risk return Tradeoff written by Dimitrios Koutmos and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The intertemporal risk-return tradeoff is the cornerstone of modern empirical finance and has been the focus of much debate over the years. The reason for this is because extant literature cannot agree as to the very nature of this important relation. This is troublesome in terms of academic theory given that it challenges the notion that investors are risk-averse agents and is furthermore troublesome in practice given that market participants expect to be rewarded with higher expected returns in order to take on higher risks. The motivation for this thesis stems from the conflicting and inconclusive empirical evidence regarding the risk-return tradeoff. Through each of the chapters, it sheds new light on possible reasons as to why extant studies offer conflicting evidence and, given the enhancements and innovative approaches proposed here, it provides empirical evidence in support of a positive intertemporal risk-return tradeoff when examining several international stock markets. The research questions this thesis addresses are as follow. Firstly, is it possible that extant conflicting evidence is manifested in the use of historical realized returns to proxy for investors' forward-looking expected returns? Secondly, can accounting for shifts in investment opportunities (i.e. intertemporal risk) better explain investors' risk aversion and changes in the dynamic risk premium? Thirdly, is it possible that conflicting findings are the result of neglecting to account for the possibility that there exist heterogeneous investors in the stock market with divergent expectations? The empirical findings can be summarized as follows; firstly, there is a strong possibility that many existing studies cannot find a positive risk-return relation because they are relying on ex post historical realized returns as a proxy for investors' forward-looking expected returns. Secondly, there is evidence in favor of the Merton (1973) notion that there exists intertemporal risk which impacts investors and that this type of risk should be considered. This has been also another reason why extant literature cannot agree on the nature of the intertemporal risk-return tradeoff. Finally, even after accounting for investor heterogeneity, the findings provide support for the Merton (1973) theoretical Intertemporal Capital Asset Pricing Model. Namely, in contrast to existing studies on the matter, there is evidence of fundamental traders over longer horizons and no evidence of feedback traders at such horizons. Although this sheds new light on some of the driving forces behind stock prices, the nature of investors' degree of risk aversion seems to be best supported by the Merton (1973) theoretical Intertemporal Capital Asset Pricing Model.
Download or read book Time Varying Risk Return Tradeoff in the Stock Market written by Hui Guo and published by . This book was released on 2012 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using a semiparametric estimation technique, we show that the risk-return tradeoff and the Sharpe ratio of the stock market increases monotonically with the consumption wealth ratio (CAY) across time. While early studies have commonly interpreted such a finding as evidence of the countercyclical variation in aggregate relative risk aversion (RRA), we argue that it mainly reflects changes in investment opportunities for two reasons. First, we fail to reject the null hypothesis of constant RRA after controlling for CAY as a proxy for the hedge against changes in the investment opportunity set. Second, by contrast with habit formation models but consistent with ICAPM, we find that loadings on the conditional stock market variance scaled by CAY are negatively priced in the cross-sectional regressions. For illustration, we replicate the countercyclical stock market risk-return tradeoff using simulated data from Guo's (2004) limited stock market participation model, in which RRA is constant and CAY is a proxy for shareholders' liquidity conditions.
