A good book for the designer of energy risk managment tools.......2005-09-29
Not for the average industry professional.......2004-08-20
Good overview.......2004-06-07
In chapter 5 the author presents techniques for energy modeling that go beyond the used of the convenience yield by using forward pricing techniques. The goal is to describe the dynamics of future contract prices that takes into account the correlations with other futures, and not on the price evolution of a single contract. Thus it is the `forward curve' that is relevant for obtaining a useable model for derivative cash flow. The HJM model is presented as one of these, with changes in the forward curve over a particular time interval represented as a linear combination of random perturbations. For energy markets, each perturbation is specified by a deterministic shape function multiplied by a Gaussian factor. The unobservability of the factors determining the forward curve evolution makes the use of historical data mandatory if the parameters are to be estimated. But lack of sufficient historical data and its nonstationarity complicate this estimation. The authors discuss the Schwartz-Smith multi-factor model as an example of a forward curve dynamics model and give some solutions. They then move on to a model that specifies the dynamics for only the contracts that are actually traded, which in the literature are called `market models.' The model they actually discuss is a multivariate geometric Brownian motion representation of the forward curve dynamics, where the volatility and drift functions are linear functions of the forward prices. The authors then derive the `discrete string models', where it is assumed that the number of factors is equal to the number of contracts, and the random factors are governed by ordinary Brownian motion. String models are represented as having the advantage of being able to directly observe the factors in the historical data. The authors apply string models to multi-commodity cases, and discuss an example for monthly forward prices. They show how to match the current forward curve, the option prices, and the correlation structure for this model.
The discussion in chapter 7 revolves around finding better models for the dynamics of power prices that capture the special properties of energy prices, such as mean reversion and seasonality, and the need for stable models. They therefore introduce `hybrid models', which they claim give a more natural representation of the dynamics of power prices, make use of nonprice forward-looking information, and can take the historical data on power prices and then extend it to information on fuel prices, outages, etc. The construction of these models is based on the use of nonlinear transformations on a collection of random variables. The random variables are essentially the system demand, natural gas and oil price, outages, emission prices, and weather at a particular time. The power price then can be written as a function of the dynamics of these factors, the latter written by the authors in terms of the corresponding tradables. Recognizing that hedging cannot be done on some of these factors, they adjust the power price formula so that the power tradables, i.e. the forwards and option prices, are exactly matched. This matching transformation is chosen so that if the forward contracts and options are priced using the adjusted formula, one recovers the exact current prices. The model, as the authors summarize it, is an attempt to explain the behavior of the tradables in terms of the evolution of the underlying factors and static adjustments to the terminal probability distribution. Historical information on the tradables and spot products is not used to calibrate the model, but it is used to validate the model. The authors distinguish between `reduced-form' hybrid models, where the transformation is calibrated from the historical prices, and `fundamental' hybrid models, where the transformation is calibrated from the market structure and is only tested on the historical prices. The authors discuss an example of a reduced-form hybrid model that is heavily parametrized, but has the advantage of using price data more efficiently. The rest of the chapter concentrates on fundamental hybrid models, with the author first discussing how power prices are formed in competitive markets. They consider a typical pool market, with the price determined via auction mechanisms. The authors then try to identify and characterize the underlying random variables that actually affect power prices. The time series for the price of power is written in terms of the demand using a `bid stack' function. The bid stack function is approximated by a `generation stack' that is found for a given time by sorting generation units by their generation costs. This approximation is checked by comparing the marginal generation costs generated by the generation stack with the distribution of power prices determined by the time series via the bid stack. There should be agreement in both approaches between the higher order moments. This comparison forms the basis of the authors' hybrid approach to modeling power prices. A transformation is found which relates the marginal generation costs to the distribution of power prices with the requirement that the prices of market instruments used for calibration are matched, and the higher moments are (approximately) preserved. The transformation is not unique, and in fact a family of transformations induced by the multiplication and stack scaling operators can be found.
Excellent subject treatment.......2004-05-06
To me, the greatest strength of the book lies in its fairly detailed analysis of what DOESN'T work, i.e. why common models and methods from the financial and other commodity realms can not be successfully grafted onto the energy market without risking significant valuation and cash flow prediction errors. The hybrid model they formulate towards the end of the book is very similar to Skantze and Ilic (2001). The departure from most previous models is that they attempt to use the markets to formulate and calibrate the structure instead of relying too much on past historical price/load data, which without some empirical understanding of the underlying processes, is fraught with danger due to rapidly evolving nature of the power market (or at least once rapidly evolving--it seems to be a little static at the moment).
Some familiarity with the market and stochastic/statistical mathematics is assumed. References to specific topics and more in depth analysis of particular subjects are good. The authors have a grip on real-world trading, risk, and cashflow issues, which makes this a useful reference for just about anyone associated with those aspects of the power market. I recommend it.

The Warren Buffett Portfolio: Mastering the Power of the Focus Investment Strategy
Robert G. Hagstrom Manufacturer: Wiley ProductGroup: Book Binding: Paperback Similar Items:
ASIN: 0471392642 |
Amazon.com
It's no secret that most mutual funds fail to beat the performance of the S&P 500. And if the pros can't beat the averages, it's not unreasonable to assume that most individual investors can't, either. Why? According to Robert Hagstrom, author of The Warren Buffett Portfolio, a big reason is the industry's emphasis on diversification. In the interest of minimizing risk, many investors have "become intellectually numb to its inevitable consequence: mediocre results." As a result, they wind up owning too many stocks and churn their portfolios unnecessarily (for example, the average mutual fund holds 100 stocks and turns over 80 percent of its portfolio annually). In The Warren Buffett Portfolio, Hagstrom shows how Buffett and others use the idea of focus investing to organize winning portfolios.Unlike Hagstrom's first book, The Warren Buffett Way, which describes how the world's greatest investor selects individual companies, this book looks at the mathematics, the psychology, and the mental models necessary to build a successful portfolio. The basic ideas: Pick no more than 10 to 15 companies with good track records and high probabilities of future success; plan to hang onto them for at least five years; and ignore predictions and the sometimes terrifying swings in market behavior. It's hard to argue with Hagstrom's approach, especially when he practices what he preaches. His fund, the Legg Mason Focus Trust, has 15 stocks, an annual turnover rate of 9 percent, and percentage annual returns in the mid-30s. For thoughtful investors and devotees of Warren Buffett, who are looking for more than the next hot stock tip, The Warren Buffett Portfolio is well-written guide. Recommended. --Harry C. Edwards
Book Description
The Warren Buffett Way provided the first look into the strategies that the master uses to pick stocks. A New York Times bestseller, it is a valuable and practical primer on the principles behind the remarkable investment run of the famed oracle of Omaha. In this much-awaited companion to that book, author Robert Hagstrom takes the next logical step, revealing how to profitably manage stocks once you select them. THE WARREN BUFFETT PORTFOLIO will help you through the process of building a superior portfolio and managing the stocks going forward.Customer Reviews:

A true treasure among modern investment books..........2003-07-03
The heart of this book rests on the premise that a proper portfolio must be "diverse" (i.e. must include 40 to 100 different companies) in order to remain "safe" and avoid a loss of capital. However, while such a notion may decrease short-term volatility, it does not necessarily increase returns. Hagstrom examines investment guru Warren Buffett's ideas on the subject, such as "knowledge decreases risk, not the number of stocks in your portfolio". Such an approach makes sense. Which is better, to own a few companies that you know everything about, or a lot of companies that you know little or nothing about? The less you know about a company, the more likely it is that an unforeseen event will sneak up on you and hammer your portfolio.
The book also addresses the fallacy of "re-balancing a portfolio". Again, Warren asks, why are you selling off your best company to buy a bunch of under-performing companies? Such a line of thinking is akin to saying "Michael Jordan takes too many shots and makes too much money relative to the other players on his team, so he should be traded to another team for three players so as to decrease the risk of an injury hurting the team... or we should give more shot opportunities to players of lesser talent so that the team doesn't become dependent on Michael Jordan to win." Nobody ever won an NBA Championship with run-of-the-mill players, but the Bulls won six NBA titles by relying on Michael Jordan.
It's this stalwart advance in the face of conventional wisdom that separates this book from most in the stock investment genre. Give it a try. You may find it's the most profitable book you've ever purchased...

The Power of Portfolios: What Children Can Teach Us About Learning and Assessment
Elizabeth A. Hebert Manufacturer: Jossey-Bass ProductGroup: Book Binding: Paperback Similar Items:
ASIN: 0787958719 |
Book Description
How should a student's learning be measured and assessed? Standardized tests identify the most knowledgeable child, whereas student portfolios can identify the knowledge level of each individual child. In The Power of Portfolios, Elizabeth A. Hebert offers a practical and imaginative approach for using portfolios with elementary level students and shows how the portfolio process can serve as a powerful motivational tool by encouraging students to assess their own work, set goals, and take responsibility for future learning. Throughout the book Hebert relates stories that illuminate the lessons learned -- by the students, teachers, and principal -- from a school that has used portfolios for more than a decade. Rather than prescribing what the portfolio should contain and how it should be assessed, she offers practical guidance, including classroom exercises, for making the portfolio experience a success for the students, the teachers, and the school as a whole.

Power and Portfolios: Best Practices for High School Classrooms
Jim Mahoney Manufacturer: Heinemann ProductGroup: Book Binding: Paperback Similar Items:
ASIN: 0867095296 |
Book Description
Portfolios are a driving force in student motivation and growth. Some are so stunning that they are the very models of what writing-reading workshops set out to doto engender in students confidence in their own abilities and to inspire them to become sophisticated users of language. But how do you set up such a workshop and how can you achieve such remarkable results?
For many years, Jim Mahoney has conducted workshops on the workshop approach to middle and senior high school teachers. Now he has written about the day-to-day practices of the writer's and reader's workshop, explaining the theory and the nitty-gritty details of putting together a portfolio in a way that goes beyond being a mere recipe. From his first chapter on the sharing of power to subsequent chapters building on Nancie Atwell's principles of time, ownership, and response, Jim shows how to structure and run a classroom with portfolios as the centerpiece.
And Jim truly practices what he preacheswhen he asks his high school students to write, he writes alongside them or in front of them, using a transparency and letting them see the tentative moves, corrections, and adjustments a writer makes. Literary letters, essays, stories, poemsany and all genres are grist for the mill of producing what Jim calls "a writing state of mind." His success in promoting this state is apparent in the many compelling student samples integrated throughout his text.
If you are interested in making the move from a teacherdirected classroom to a student-centered one, in learning from and with your students, and in sharing the joys and the power of reading and writing, you find no better guide than Jim Mahoney and his Power and Portfolios.

Proof There's Power in Portfolios.......2002-06-18
Most helpful to me were the details of the student created portfolio. In Chapter 3, "The Nitty-Gritty Details," Mahoney breaks down the portfolio into its components and explains the hows and whys of each. Throughout the book, Mahoney includes forms he has used in conferences, for student reflection on their Writer's Notebook and Literary Log, and for thorough student self-evaluation. You'll even find creative ideas for the portfolio cover itself (save your pizza boxes).
Mahoney skillfully weaves stories from his own classroom into his explanations and shares with us some exceptional writing done by students. He describes how the portfolios become more than a grade to the students, many of whom are willing to stay after school on the LAST day to perfect their portfolios, even though grades have been given and report cards issued.
Portfolios are a way to give students ownership of their work and to involve them in assessing their own writing. These creations become more than just projects to both Mahoney's students and their families. They become a way to explore their lives and communicate with others in a powerful and moving way.

It's Earnings That Count : Finding Stocks with Earnings Power for Long-term Profits
Hewitt Heiserman Jr. Manufacturer: McGraw-Hill ProductGroup: Book Binding: Hardcover Similar Items:
ASIN: 0071423230 |
Book Description
An innovative way to see through a company's published numbers to discover its true investment potential
This book gives you a blueprint for finding a great growth stock for the next decade without taking on a lot of risk in the process. Inspired by the writings of Benjamin Graham, It's Earnings That Count examines a firm’s earnings quality from the perspective of a “defensive” investor who wants to avoid committing ruinous mistakes as well as the “enterprising” investor who seeks Wall Street’s next great opportunities. Unfortunately, as recent market history has shown, the traditional income statement is ill-suited to meeting the needs of these sometimes opposing viewpoints. As a result, investors can buy shares of a seemingly profitable company that, in fact, has poor earnings quality.
However, the author’s trademarked Earnings Power Chart combines Graham’s two personalities to reveal, in picture form, whether a company possesses authentic earnings power for long-term growth. Using the world-famous William Wrigley Jr. Company gum-maker as a case study, you will learn how to build these two alternate profit-and-loss statements to protect yourself. Since this book is written in plain English, you do not need to be an MBA or accountant to follow these step-by-step instructions.
Giving investors the tools they need to turn the tables in their favor, It's Earnings That Count covers:

The Citizen Investor: The Power of Ownership
Phil Dow , and Paul B. Brown Manufacturer: RBC Dain Rauscher ProductGroup: Book Binding: Hardcover ASIN: 0974319007 |
Book Description
There are no guarantees when it comes to investing.And if you've heard it once, you've heard it a thousand times, "past performance is no guarantee of future results." And yet, year in and year out, the same companies ouperform the pack. They aren't flashy. And they certainly will not generate the highest returns over one week, one month or one year. Yet, every time you look at the best performing stocks over a three, five, or ten-year (or even longer) period, there they are. Doesn't it make sense to consider making these strong performers a core part of your portfolio? Phil Dow, director of equity strategy for RBC Dain Rauscher, one of the nation's leading brokerage firms, thinks so. Here in straight forward, no-nonsense language, Dow shows you how to identify the market's "Bulldog Stocks" and what you should do with them once you find them. (Hint: You OWN them for the long term.) If it is time to get back into the market, or to readjust your portfolio, THE CITIZEN INVESTOR is a great place to start.
