An Intertemporal CAPM with Stochastic Volatility


Book Description

This paper studies the pricing of volatility risk using the first-order conditions of a long-term equity investor who is content to hold the aggregate equity market rather than tilting towards value stocks and other equity portfolios that are attractive to short-term investors. We show that a conservative long-term investor will avoid such tilts in order to hedge against two types of deterioration in investment opportunities: declining expected stock returns, and increasing volatility. Empirically, we present novel evidence that low-frequency movements in equity volatility, tied to the default spread, are priced in the cross-section of stock returns.

Strategic Asset Allocation


Book Description

Academic finance has had a remarkable impact on many financial services. Yet long-term investors have received curiously little guidance from academic financial economists. Mean-variance analysis, developed almost fifty years ago, has provided a basic paradigm for portfolio choice. This approach usefully emphasizes the ability of diversification to reduce risk, but it ignores several critically important factors. Most notably, the analysis is static; it assumes that investors care only about risks to wealth one period ahead. However, many investors—-both individuals and institutions such as charitable foundations or universities—-seek to finance a stream of consumption over a long lifetime. In addition, mean-variance analysis treats financial wealth in isolation from income. Long-term investors typically receive a stream of income and use it, along with financial wealth, to support their consumption. At the theoretical level, it is well understood that the solution to a long-term portfolio choice problem can be very different from the solution to a short-term problem. Long-term investors care about intertemporal shocks to investment opportunities and labor income as well as shocks to wealth itself, and they may use financial assets to hedge their intertemporal risks. This should be important in practice because there is a great deal of empirical evidence that investment opportunities—-both interest rates and risk premia on bonds and stocks—-vary through time. Yet this insight has had little influence on investment practice because it is hard to solve for optimal portfolios in intertemporal models. This book seeks to develop the intertemporal approach into an empirical paradigm that can compete with the standard mean-variance analysis. The book shows that long-term inflation-indexed bonds are the riskless asset for long-term investors, it explains the conditions under which stocks are safer assets for long-term than for short-term investors, and it shows how labor income influences portfolio choice. These results shed new light on the rules of thumb used by financial planners. The book explains recent advances in both analytical and numerical methods, and shows how they can be used to understand the portfolio choice problems of long-term investors.




Market Volatility


Book Description

Market Volatility proposes an innovative theory, backed by substantial statistical evidence, on the causes of price fluctuations in speculative markets. It challenges the standard efficient markets model for explaining asset prices by emphasizing the significant role that popular opinion or psychology can play in price volatility. Why does the stock market crash from time to time? Why does real estate go in and out of booms? Why do long term borrowing rates suddenly make surprising shifts? Market Volatility represents a culmination of Shiller's research on these questions over the last dozen years. It contains reprints of major papers with new interpretive material for those unfamiliar with the issues, new papers, new surveys of relevant literature, responses to critics, data sets, and reframing of basic conclusions. Included is work authored jointly with John Y. Campbell, Karl E. Case, Sanford J. Grossman, and Jeremy J. Siegel. Market Volatility sets out basic issues relevant to all markets in which prices make movements for speculative reasons and offers detailed analyses of the stock market, the bond market, and the real estate market. It pursues the relations of these speculative prices and extends the analysis of speculative markets to macroeconomic activity in general. In studies of the October 1987 stock market crash and boom and post-boom housing markets, Market Volatility reports on research directly aimed at collecting information about popular models and interpreting the consequences of belief in those models. Shiller asserts that popular models cause people to react incorrectly to economic data and believes that changing popular models themselves contribute significantly to price movements bearing no relation to fundamental shocks.




The Investor's Dilemma Decoded


Book Description

Few aspects of life are as important as personal finance, as subject to your control, and as suffused with misinformation, noise, and confusion. Now, authors Dr. Roger D. Silk and Katherine A. Silk cut through that confusion and share with you the fruits of their knowledge and experience developed over the last 43 years. After completing a Ph.D. at Stanford where he studied at the cutting edge of finance theory, Dr. Silk's experience includes managing billions of dollars at the World Bank and running a family office for one of the nation's wealthiest families. For the last 26 years as CEO of the nation's leading firm which advises high net worth individuals on financial and other aspects of their philanthropy, Dr. Silk has worked with countless individual investors and financial professionals. Katherine Silk, who holds a master's in history from Stanford, adds a valuable and often-missing historical perspective. Their weekly blog, dealing in depth with a variety of financial, economic, and planning issues, is read by thousands. Unlike many authors in the Personal Finance space, the Silks have the deep technical expertise (it's hard to get a graduate degree from Stanford without it), decades of experience, and the rare ability to express complex ideas in clear, easy-to-understand prose. When Gary Taubes wrote The Case for Keto, he considered calling it “How to Think About How to Eat.” Similarly, The Investor's Dilemma Decoded could be titled “How to Think about How to Invest.” Investor's Dilemma gives you the tools that 99.9% of investors never master — these tools allow you to understand how to think about almost any category of investment, and almost any investment product or program. In addition, the authors take a deep dive into topics including What actually generates investment returns (it's probably not what you think) Is owning a home an investment (you'll learn why the answer is sometimes yes, and sometimes no) Should you own gold (clue: the largest gold holders in the world are central banks) What is a hedge, and are commodity funds an inflation hedge What many well-known investment personalities get wrong on about returns (they tell the truth, but it's the wrong truth) What risk is, and isn't, and why the “safe” course might be the riskiest (but the government says it's safe). How professional financial advisors can add huge value to their individual clients (it's not by picking the best stocks) Should you read this book? If you want to understand how professionals think about investing, about what is realistic and unrealistic, and learn to spot the difference between a Bull Market and Bull-xxxx, the answer is yes.
