Book Description
The paper investigates the portfolio allocation effects of increased asset co-movements during extreme market downturns. We develop a model for the state variables underlying the stock price process that allows for increased and asymmetric dependence between extreme return realizations. We isolate the portfolio hedging demands that arise due to extreme co-movements and find a substantial shift of the portfolio holdings toward the risk-free asset. Ignoring the dependence between extreme events gives rise to sizeable economic losses. It penalizes investors for holding levered positions, and reduces the gains from diversification. These findings are robust along different specifications of the utility function, varying levels of risk aversion, and alternative modeling assumptions of extreme co-movements and conditional correlation.

Book Description
Based on a recent theorem due to the authors, it is shown how the extreme tail dependence between an asset and a factor or index or between two assets can be easily calibrated. Portfolios constructed with stocks with minimal tail dependence with the market exhibit a remarkable degree of decorrelation with the market at no cost in terms of performance measured by the Sharpe ratio.

Book Description
As today's preeminent doomsday investor Mark Spitznagel describes his Daoist and roundabout investment approach, “one gains by losing and loses by gaining.” This is Austrian Investing, an archetypal, counterintuitive, and proven approach, gleaned from the 150-year-old Austrian School of economics, that is both timeless and exceedingly timely. In The Dao of Capital, hedge fund manager and tail-hedging pioneer Mark Spitznagel—with one of the top returns on capital of the financial crisis, as well as over a career—takes us on a gripping, circuitous journey from the Chicago trading pits, over the coniferous boreal forests and canonical strategists from Warring States China to Napoleonic Europe to burgeoning industrial America, to the great economic thinkers of late 19th century Austria. We arrive at his central investment methodology of Austrian Investing, where victory comes not from waging the immediate decisive battle, but rather from the roundabout approach of seeking the intermediate positional advantage (what he calls shi), of aiming at the indirect means rather than directly at the ends. The monumental challenge is in seeing time differently, in a whole new intertemporal dimension, one that is so contrary to our wiring. Spitznagel is the first to condense the theories of Ludwig von Mises and his Austrian School of economics into a cohesive and—as Spitznagel has shown—highly effective investment methodology. From identifying the monetary distortions and non-randomness of stock market routs (Spitznagel's bread and butter) to scorned highly-productive assets, in Ron Paul's words from the foreword, Spitznagel “brings Austrian economics from the ivory tower to the investment portfolio.” The Dao of Capital provides a rare and accessible look through the lens of one of today's great investors to discover a profound harmony with the market process—a harmony that is so essential today.

Book Description
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.

Book Description
Alternative Investments: A Primer for Investment Professionals provides an overview of alternative investments for institutional asset allocators and other overseers of portfolios containing both traditional and alternative assets. It is designed for those with substantial experience regarding traditional investments in stocks and bonds but limited familiarity regarding alternative assets, alternative strategies, and alternative portfolio management. The primer categorizes alternative assets into four groups: hedge funds, real assets, private equity, and structured products/derivatives. Real assets include vacant land, farmland, timber, infrastructure, intellectual property, commodities, and private real estate. For each group, the primer provides essential information about the characteristics, challenges, and purposes of these institutional-quality alternative assets in the context of a well-diversified institutional portfolio. Other topics addressed by this primer include tail risk, due diligence of the investment process and operations, measurement and management of risks and returns, setting return expectations, and portfolio construction. The primer concludes with a chapter on the case for investing in alternatives.
