Ralph Vince – författare

The cornerstone of money management and portfolio optimization techniques has remained the same throughout history: maximize gains and minimize risk. Yet, asserts Ralph Vince, the widely accepted approaches of combining assets into a portfolio and determining their relative quantities are wrong—and will cost you. They illuminate nothing, he says, aside from providing the illusion of safety through diversification. Although numerous Nobel Prizes have been awarded based on some of those widely accepted principles, their popular acceptance does not constitute real-world validation. What has been needed is a viable alternative to directly address these real-world dictates. In The Leverage Space Trading Model, Vince offers a groundbreaking contribution to the literature that builds on a lifetime of expert analysis to deliver not only a superior new portfolio model, but takes the entire discipline of portfolio management to a new level. In this book, Vince—who has made many important intellectual contributions to the field for over two decades—departs radically from informed orthodoxy to present an entirely new approach to portfolio management. At its core, The Leverage Space Trading Model basically tells how resources should be combined to maximize safety and profitability given the dictates of the real world. But, as the author points out, given the complex and seemingly pathological character of human desires, we are presented with a fascinating puzzle. Research has found that human beings do not primarily want to maximize gains—our psychological makeup is such that we instead tend to possess seemingly more complex desires. If the models don't work, if we are ultimately unable to satisfy our more complex desires, what's the alternative? As Vince shows, the answer is to utilize the Leverage Space Model as a "framework" to achieve the specific ends a trader or portfolio manager seeks. The author's new allocation paradigm avoids the troubles that come with mean variance models—which most models are—and quantifies drawdowns to achieve a growth-optimal portfolio within a given drawdown constraint, in a manner that satisfies these seemingly pathological human desires. And for those who don't wish to get involved with the mathematics, Vince has presented the text in a manner of two congruent, simultaneous channels, with math and without. Most simply put, this book will change how you think about money management and portfolio allocations.

THE NEW MONEY MANAGEMENT In his bestselling Portfolio Management Formulas and TheMathematics of Money Management, Ralph Vince brought the complexmathematics of probability and modern portfolio management theorydown to earth for traders and investors. He introduced innovativenew ways they could be used to maximize account managementdecisions. Now, in this groundbreaking new book, Vince takes aquantum leap forward to provide investment professionals with aproven new approach to portfolio management that overturns nearly ahalf-century of accepted wisdom about asset allocation and moneymanagement. The culmination of Ralph Vince's years spent probing the limits ofthe mathematics of portfolio management, The New Money Managementelaborates on his celebrated Optimal f notion--a concept which willbe familiar to readers of either of Vince's previous books--toprovide a revolutionary portfolio management model designed tooptimize account performance, not just in the long run, but atvirtually any given point in time. Unlike traditional models which focus on risk and reward ascompeting entities, the approach to portfolio constructiondescribed in this book concentrates on obtaining optimal synergyamong all of the various components of a given portfolio. Unlikeprevious portfolio models which assumed an a priori distribution toreturns, usually with returns being normally distributed, this newmodel is applicable to any distributional form of return. In The New Money Management, Ralph Vince once again demonstrateshis critically acclaimed talent for talking about highly complexconcepts in practical, real-world terms. Writing in a lively,anecdotal style, and relying on a bare minimum of math, he gentlyguides readers through the maze of complex theoretical issues whilearming them with a set of easy-to-understand, easy-to-use formulasand investment strategies that they can put into practiceimmediately. The New Money Management is an indispensable resource for allinvestment professionals, especially traders in stocks, options,and futures; institutional investors; and portfolio managers. From a leading pioneer in portfolio theory, a revolutionary newapproach to maximizing ongoing account equity . . . In his most original and accessible book yet, computer tradingsystems expert Ralph Vince introduces investment professionals to arevolutionary portfolio management model designed to optimizeaccount performance, not just in the long run, but at virtually anygiven point in time. "Ralph Vince has done it again. His work is original andlevel-headed, and contributes more than anyone else to ourunderstanding of risk. Vince's work is required reading for anyportfolio manager." --Barbara Rockefeller, President RockefellerAsset Management, Inc. "Ralph Vince's optimal concept is the single best strategy fordetermining how many contracts or number of shares to buy whenfirst entering a trade. This latest book breaks new ground in thefield of money management." --Howard A. Bernstein, President HBCapital Management, Inc. "I would encourage all progressive portfolio managers to understandRalph Vince's methodology. His works continue to be a rigorouslywell-researched and documented method of risk control and assetallocation. His focus is unique in our industry." --Michael J.McCarthy, Portfolio Manager Signalert Corporation "A great book, if you want to get rich quickly without going brokefirst, to help you formulate your risk and trading strategy."--Harry Ploss Private Managed Futures Investor and Actuary

Explores two neglected mathematical tools essential for competing successfully in today's frenzied commodities markets: quantity, which shows the proper amounts a trader should trade for a given market and system, and intercorrelation of returns (diversification), which shows not only which markets and systems to trade, but how to diversify with respect to trading the right quantities for each market. By using these lesser known tools in conjunction with the more popular trade/system selection tools, readers will see mathematically how success in the markets can be achieved, and how ``success'' without using all three is most likely incidental. In addition, non-stationary distribution of profits and losses and drawdowns are incorporated into the discussions to expose traders to the highs and lows of commodities markets and how best to leverage their assets.

Every futures, options, and stock markets trader operates under a set of highly suspect rules and assumptions. Are you risking your career on yours? Exceptionally clear and easy to use, The Mathematics of Money Management substitutes precise mathematical modeling for the subjective decision-making processes many traders and serious investors depend on. Step-by-step, it unveils powerful strategies for creating and using key money management formulas--based on the rules of probability and modern portfolio theory--that maximizes the potential gains for the level of risk you are assuming. With them, you'll determine the payoffs and consequences of any potential trading decision and obtain the highest potential growth for your specified level of risk. You'll quickly decide: What markets to trade in and at what quantities When to add or subtract funds from an account How to reinvest trading profits for maximum yield The Mathematics of Money Management provides the missing element in modern portfolio theory that weds optimal f to the optimal portfolio.

The Handbook of Portfolio Mathematics "For the serious investor, trader, or money manager, this book takes a rewarding look into modern portfolio theory. Vince introduces a leverage-space portfolio model, tweaks it for the drawdown probability, and delivers a superior model. He even provides equations to maximize returns for a chosen level of risk. So if you're serious about making money in today's markets, buy this book. Read it. Profit from it."—Thomas N. Bulkowski, author, Encyclopedia of Chart Patterns"This is an important book. Though traders routinely speak of their 'edge' in the marketplace and ways of handling 'risk,' few can define and measure these accurately. In this book, Ralph Vince takes readers step by step through an understanding of the mathematical foundations of trading, significantly extending his earlier work and breaking important new ground. His lucid writing style and liberal use of practical examples make this book must reading."—Brett N.
