Book Description
In this article, we characterize efficient contingent claims in a context of transaction costs and multidimensional utility functions. The dual formulation of utility maximization helps us outline the key notion of cyclic anticomonotonicity. Moreover, after defining a utility price in this multidimensional setting, we provide a measure of strategies inefficiency and a tool allowing to effectively compute this measure with the help of cyclic anticomonotonicity.

Book Description
"The decisions that investment professionals and fund managers make have a direct impact on investor return. Unfortunately, the best implementation methodologies are not widely disseminated throughout the professional community, compromising the best interests of funds, their managers, and ultimately the individual investor. But now there is a strategy that lets professionals make better decisions. This valuable reference answers crucial questions such as: * How do I compare strategies? * Should I trade aggressively or passively? * How do I estimate trading costs, ""slice"" an order, and measure performance? and dozens more. Optimal Trading Strategies is the first book to give professionals the methodology and framework they need to make educated implementation decisions based on the objectives and goals of the funds they manage and the clients they serve."

Book Description
We derive an explicit solution to a continuous time dynamic portfolio problem assuming investors maximize their welfare from a consumption stream in an incomplete market where returns to the securities are predictable but costly to trade. The solution is phrased in terms of a risk-sensitive Riccati equation. We show that the optimal trading strategy is to target a portfolio that is the optimal solution to a frictionless (or 'no-cost') dynamic portfolio problem but where the returns to the assets have been adjusted for costs; that is they have been expressed on a net rather than gross basis. The legacy portfolio (the inherited undesirable positions) are then traded away in line with a backward-looking optimal execution problem. We show that the utility gradient is a stochastic discount factor that prices the assets net returns. Thus we are able to generalise some of the results of the martingale approach to dynamic portfolio theory to market with frictions.

Book Description
We provide a price characterization of efficient contingent claims - i.e., chosen by at least a rational agent-in multiperiod economies with market frictions. Frictions include market incompleteness, transaction costs, short-selling and borrowing costs. We characterize the inefficiency cost of a trading strategy - its required investment minus the largest amount necessary to obtain the same utility level - and we propose a measure of portfolio performance. We show that arbitrage bounds cannot be tightened based on efficiency without restricting preferences or endowments. We observe common investment strategies becoming inefficient with market frictions, and others rationalized by them.

Book Description
Efficiently Inefficient describes the key trading strategies used by hedge funds and demystifies the secret world of active investing. Leading financial economist Lasse Heje Pedersen combines the latest research with real-world examples and interviews with top hedge fund managers to show how certain trading strategies make money--and why they sometimes don't. Pedersen views markets as neither perfectly efficient nor completely inefficient. Rather, they are inefficient enough that money managers can be compensated for their costs through the profits of their trading strategies and efficient enough that the profits after costs do not encourage additional active investing. Understanding how to trade in this efficiently inefficient market provides a new, engaging way to learn finance. Pedersen analyzes how the market price of stocks and bonds can differ from the model price, leading to new perspectives on the relationship between trading results and finance theory. He explores several different areas in depth--fundamental tools for investment management, equity strategies, macro strategies, and arbitrage strategies--and he looks at such diverse topics as portfolio choice, risk management, equity valuation, and yield curve logic. The book's strategies are illuminated further by interviews with leading hedge fund managers: Lee Ainslie, Cliff Asness, Jim Chanos, Ken Griffin, David Harding, John Paulson, Myron Scholes, and George Soros.

Book Description
A comprehensive guide to the dynamic area of finance known as market microstructure Interest in market microstructure has grown dramatically in recent years due largely in part to the rapid transformation of the financial market environment by technology, regulation, and globalization. Looking at market transactions at the most granular level—and taking into account market structure, price discovery, information flows, transaction costs, and the trading process—market microstructure also forms the basis of high-frequency trading strategies that can help professional investors generate profits and/or execute optimal transactions. Part of the Robert W. Kolb Series in Finance, Market Microstructure skillfully puts this discipline in perspective and examines how the working processes of markets impact transaction costs, prices, quotes, volume, and trading behavior. Along the way, it offers valuable insights on how specific features of the trading process like the existence of intermediaries or the environment in which trading takes place affect the price formation process. Explore issues including market structure and design, transaction costs, information flows, and disclosure Addresses market microstructure in emerging markets Covers the legal and regulatory issues impacting this area of finance Contains contributions from both experienced financial professionals and respected academics in this field If you're looking to gain a firm understanding of market microstructure, this book is the best place to start.

Book Description
In the presence of transaction costs, a risk-return trade-off exists between the quality and the cost of a replicating strategy. In that context, I show how to expand the set of all possible time-based strategies through the introduction of a multi-scale class of strategies, which consist in rebalancing different fractions of an option portfolio at different time frequencies. The method, based on time-scale diversification, is to dynamic replication what investment in diversified portfolios is to static portfolio selection: in a dynamic context, one may enjoy the benefits of diversification by using different time scales in trading the same asset.

Book Description
This study considers the relationship between trading volumes, transactions costs, and the profitability of momentum strategies using data from the UK. We demonstrate that round-trip transactions costs for selling loser firms are around double those of buying winners, and in particular, the costs of selling low volume losers is more than twice as high as the cost of selling low volume winners. By contrast, there are only modest differences between the costs of buying winners and losers, irrespective of their volume levels. Yet we observe that, even in net terms, momentum strategies based on low volume stocks are more profitable than those using high volume stocks. We also note important differences between transactions costs measured using quoted versus effective spreads. Altogether, our findings should sound a word of caution for any study attempting to evaluate the impact of transactions costs on momentum profitability that such costs are very heterogeneous across firms and trade types, implying that they require careful calculation.
