Modeling Financial Markets : Using Visual Basic.NET and Databases to Create Pricing, Trading, and Risk Management Models Review

Modeling Financial Markets : Using Visual Basic.NET and Databases to Create Pricing, Trading, and Risk Management Models
Average Reviews:

(More customer reviews)
This is a "How To Program" book which uses financial applications as samples. It is heavy on programming basics and scratches the surface of financial modeling. That's fine if that's what you expect from the book, but the title led me to believe that I'd learn modeling techniques. I expected a book that assumed proficiency in VB and dealt with moderate to advanced financial topics.
If you already know what a where clause is and are proficient at VB.Net, this is not for you. If you know nothing about VB and want to learn it using interesting examples, this is for you.

Limitations in today's software packages for financial modeling system development can threaten the viability of any system--not to mention the firm using that system. Modeling Financial Markets is the first book to take financial professionals beyond those limitations to introduce safer, more sophisticated modeling methods. It contains dozens of techniques for financial modeling in code that minimize or avoid current software deficiencies, and addresses the crucial crossover stage in which prototypes are converted to fully coded models.

Excel Modeling and Estimation in Investments Review

Excel Modeling and Estimation in Investments

Craig W. Holden's "Excel Modeling in Investments" came as an excellent surprise to me when I received a faculty review copy from the publisher. I have long used Simon Benninga's competing text "Financial Modeling in Excel" to teach undergraduate and graduate financial modeling courses, however, I seriously am considering switching to Holden's EMinI. Holden correctly emphasizes discounting a bond's value on various yield curves, rather than a linear or fixed discount rate as in Benninga. Holden has some flaws, his layouts for binomial pricing models are inefficient for adapting to trinomial converging tree models, for example, but Holden is the only serious rival to Benninga in coverage of the major topics of modeling. Holden covers bonds, duration, convexity, portfolio optimization, financial planning, and the leading option pricing models. In addition, he covers cost of carry in the context of spot and futures prices, and interest rate parity. Holden does not cover Value at Risk, cheapest to deliver bonds, and has little on Visual Basic. However he does cover the Vasicek and Cox-Ingersoll-Ross interest rate models more thoroughly than Benninga. Holden's flaws are many: there is no index, and this is a text that cries out for one. Similarly, the footnotes are inadequate, and a broad "Further Reading" and bibliography should be here. Holden also suffers from being written as a companion text to popular finance textbooks such as Bodie Kane and Marcus, however, one always has the impression that the author was looking more to maximizing the market share of the text than really selecting the best chapters. We can only hope that Holden follows the better angels of his nature and includes more detail and chapters, perhaps on Monte Carlo simulation, VaR, and VBA programming. The CD-Rom, while helpful, is a little light, but this is the author's intention for he wishes students to build their own models from scratch.
In summary, I heartily recommend this book coupled with Benninga's more detailed "Financial Modeling in Excel" and find the practical emphasis indispensable for those working with or using a theoretical text such as Bodie Kane and Marcus. For those students that want careers in finance, this book is fundamental, primary, and necessary, for it emphasizes practical skills you will be executing everyday at a much higher level in a bank or asset management firm. Master these skills and models now before beginning your career and the acceleration of your promotions responsibilities will exceed those of your peers quickly.

Modeling Structured Finance Cash Flows with Microsoft Excel: A Step-by-Step Guide.Book & CD-ROM Review

Modeling Structured Finance Cash Flows with Microsoft Excel: A Step-by-Step Guide.Book and CD-ROM
Average Reviews:

(More customer reviews)
In structured finance, there is a tremendous discrepancy between academic literature and practice. In purporting a generalizable, scientific approach, many textbooks avoid explaining the intracacies of actual structured finance deals. The fundamental issue is that the implicit value of deal transparency required for issuer and investor tends to be overlooked by authors approaching the field from an academic background. Technical pyrotechnics that suit liquid markets fail when fees, interest rates, and other deal specifics are malleable constructs negotiated among a handful of parties. At the same time, basic bond math on an unsegregated pool of loans cannot accurately describe how assets generate cash flows and the risks faced by investors.

MFSC is the *only* book (afaik) that demonstrates how real structured finance pros bridge the void between these 2 common pitfalls made by other structured finance books. For one, the calculations that belie each component of a structured finance deal is integrated into a single model rather than considered separately. Other books may describe how cash flows pay out in a senior-sub structure, but they won't, for example, take the time to step through how funding costs and triggers affect the cash flows. The primary model also gives the user flexibility to stress the model and enables the user to treat the model as a base for all structured finance deals. Through a neatly organized inputs sheet, each component in the primary model described painstakingly anticipates the gamut of variations common to these types of deals.

All this in a book that's easy to follow and a delight to read. Five stars.

A practical guide to building fully operational financial cash flow models for structured finance transactions
Structured finance and securitization deals are becoming more commonplace on Wall Street. Up until now, however, market participants have had to create their own models to analyze these deals, and new entrants have had to learn as they go. Modeling Structured Finance Cash Flows with Microsoft Excel provides readers with the information they need to build a cash flow model for structured finance and securitization deals. Financial professional Keith Allman explains individual functions and formulas, while also explaining the theory behind the spreadsheets. Each chapter begins with a discussion of theory, followed by a section called "Model Builder," in which Allman translates the theory into functions and formulas. In addition, the companion CD-ROM features all of the modeling exercises, as well as a final version of the model that is created in the text.
Note: CD-ROM/DVD and other supplementary materials are not included as part of eBook file.

Excel Modeling &_Estimation in Corporate Finance (2008 publication) Review

Excel Modeling and_Estimation in Corporate Finance (2008 publication)

I am a huge fan of this book for several reasons. First, I believe that Professor Holden is absolutely right in trying to move finance from a calculator driven study to spreadsheets. Everyone uses spreadsheets in their work, NOT calculators. So, it is not only useful to use spreadsheets, but to learn how to build them.
Another very nice thing about this book is that it uses plain vanilla Excel. You don't need any special add-ins. This allows the user to understand what Excel on its own is capable of (and that is quite a bit). It also means the student doesn't have to buy anything more than this book to get everything the author intended.
I also like the way he takes the student along. You build the first spreadsheet with the steps he provides, and then you modify that to make the second, and then the third, and so on. You get to see the increasingly powerful things one can do with Excel. The graphs he has one build also help because it allows you to change different values and immediately see how it changes the graph. This is immensely important in helping the student develop intuitions about how the changing of this or that number affects the topic of the spreadsheet.
This book on corporate finance begins with the time value of money, a basic concept, but one that seems to elude any number of people. Part 2 takes the student into the valuation of bonds and stocks. You also get to build a yield curve (very useful) and US yield curve dynamics. Part 3 is Capital Budgeting and this means Project Net Present Value (NPV), Cost-Reducing Project, Break-Even Analysis, Adjusted Present Value, Flows to Equity, and WACC.
Part 4 takes on topics of financial planning such as Corporate Financial Planning, the Du Pont System of Ratio Analysis, and Life-Cycle Financial Planning. The last part, Part 5 deals with options and corporate finance. You get to build spreadsheets for Binomial Option Pricing, Black Scholes Option Pricing, Debt and Equity Valuation, and Real Options.
While the book uses the Brigham text notation, the accompanying CD has several important chapters with the Brealy, Keown, Ross, and Van Horne notation systems. The CD also supplies databases and problems to solve using the spreadsheets. The author also has a website for additional info and updates.
Terrific book for finance classes or as a supplement to your own study.

Financial Modeling - 2nd Edition: Includes CD Review

Financial Modeling - 2nd Edition: Includes CD
Average Reviews:

(More customer reviews)
I have used Simon Benninga's "Financial Modeling with Excel" for five years to teach undergraduate computational finance [...]. My thinking remains that my students have been well served by this textbook.
The inadequacies that limit my assessment to four stars and need to be addressed in the third edition are: 1) frustrating errors in the text and models, for which the errata sheet and corrected models (available at: [...] only improve, but do not heal. My students find new, undocumented, errors each semester. 2) the data sets and examples are getting, frankly, a little old. It is the year 2005 as I write this, but the data sets and examples end in 1999, a year in which my current students were in high school. 3) the models, while excellent as introductions to the field, are now at the point of being fundamental, rather than exemplary. This is not Prof. Benninga's fault, but as the other reviews from professionals here attest, Excel modeling has advanced in all fields (option pricing, financial statements, portfolio optimization, bond metrics, etc). When this volume was introduced, it was adequate for helping MBA and Master of Science in Finance students build essential modeling skills. Sadly, it now is only appropriate for raw beginners or undergraduates. A new text with a larger scope that addresses advances in the fields is called for. 4) While it is a subject in itself, the book is seriously hindered by not introducing basic Monte Carlo simulation in Excel. 5) No information on downloading data from BLOOMBERG, REUTERS, and other historical and market data providers. It would add to the scope of the text, but 6) fitting DCF models to yield curves also would be welcome.
Even with these criticisms, Benninga's Financial Modeling remains the best book in the field for what it seeks to accomplish. It covers the major topics of finance that are appropriately addressed with models: financial statement, firm valuation and credit metrics, portfolio construction, fixed income metrics, option pricing, etc. Benninga's FM also compares favorably with his two nearest competitors.
Powel and Baker's "The Art of Spreadsheet Modeling" is a two pronged monster: it seeks to be a meta-level theoretical work on spreadsheet modeling, and then introduces modeling Monte Carlo simulation as a fundamental component of Excel (a student edition of CrystalBall is included in the text, and is the only reason to buy this book). The gap between the two is a Grand Canyon's worth of knowledge space that this text does not fill in and nearly ignores. The student who uses only Powel and Baker is ill served; whereas if he uses Benninga, he knows how, why, when and what to model. Consider Powel & Baker as sketches of a concept car with simulated wind tunnel runs, whereas Benninga shows how to build your own kit car and drive it around. Powel and Baker's concept car is beautiful, advanced, gracious, but doesn't exist and doesn't run; Benninga's kit car is like a Lotus Super Seven: simple, runs, is a blast to drive, but is dangerous in heavy traffic and you would not want to go on a 1,000 mile journey with it (i.e. or build a DCF model for the Goldman Sachs LBO team with only Benninga).
Chandan Sengupta's "Financial Modeling Using Excel and VBA" is the only book that comes close to Benninga, and I recommend it as another perspective for my students who want to continue with financial modeling. However, Sengupta's work is flawed on two counts: 1) it is clear throughout that he had read Benninga, and 2) he dropped much of Benninga's content in favor of adding wordy explanatory paragraphs to soften the blow of the fact that modeling is mathematically and technically both boring and intense work. With those criticisms in mind, his work still has neater, leaner, more compressed models with updated contemporary detail.
There are three other books, Scott Proctor's "Building Financial Models with Microsoft Excel: A Guide for Business Professionals," which focuses on building vanilla financial statements, as does John Tjia "Building Financial Models." Mary Jackson & Mike Staunton's "Advanced Modeling in Finance using Excel and VBA" is also now dated and seriously flawed and limited in scope), however it is the next step following Benninga.
For those working in top-tier banks, the internal training and modeling documents, and examples built by colleagues, will likely surpass by light years what is offered in these books. And so for beginners, Benninga remains the the best choice and first step, until something better comes along, or Benninga himself produces a new edition.

Too often, finance courses stop short of making a connection between textbook finance and the problems of real-world business. Financial Modeling bridges this gap between theory and practice by providing a nuts-and-bolts guide to solving common financial models with spreadsheets. Simon Benninga takes the reader step by step through each model, showing how it can be solved using Microsoft Excel®. In this sense, this is a finance "cookbook," providing recipes with lists of ingredients and instructions.Areas covered include computation of corporate finance problems, standard portfolio problems, option pricing and applications, and duration and immunization. The second edition contains six new chapters covering financial calculations, cost of capital, value at risk (VaR), real options, early exercise boundaries, and term structure modeling. A new technical chapter contains a potpourri of tips for using Excel®.Although the reader should know enough about Excel™ to set up a simple spreadsheet, the author explains advanced Excel® techniques used in the book. The book includes chapters dealing with random number generation, data tables, matrix manipulation, and VBA programming. It also comes with a CD-ROM containing Excel® worksheets and solutions to end-of-chapter exercises.

Financial Modeling Review

Financial Modeling
Average Reviews:

(More customer reviews)
Simon Benninga's 3rd Edition of Financial Modelling with Excel is the single most useful book for finance students and professionals ever published and continues to offer an outstanding reference and textbook for students and practitioners of applied finance.
For further information, please use the "Look Inside" feature and examine the Table of Contents carefully, because I will emphasize selected portions.
It is difficult to overstate how useful and practical and helpful this work is for a wide audience and Financial Modelling is the single finance book I recommend for everyone after they have taken (or read themselves) Introductory Finance.
For those looking for "one-stop-shopping" for models that resemble those of professional financial analysts then there is no better value than Benninga's FM3.
Benninga's FM3 is a coal-face work for those who must make financial decisions using models. There are further specialist texts in topics covered here (credit modelling, portfolio construction, option pricing), but the models in FM3 are the first advanced models applied to loans, bonds, options, and equity portfolios. Master these and then specialized texts are easier to digest.
"Cookbook" metaphors are too strong and do not do this work justice, for Financial Modelling 3rd (FM3) is not a mere collection of recipes but rather topical introduction, explanation, and then direct technique.
If we can make a comparison with a "cookbook" then FM3 falls somewhere between "The Joy of Cooking" and "Mastering the Art of French Cooking." "Joy" combines chapters on technique, ingredients, and tools with dense pages of endless recipes, whereas "Mastering" emphasises technique and a few well-selected recipes.
The welcome new chapters cover bank valuation, the Black-Litterman approach to portfolio optimization, and Monte Carlo methods and applications to option pricing, and the previous 2nd edition's small chapter on using array functions and formulas has been expanded. The chapter on data downloads from YAHOO is also welcome, especially for those on a budget.
There is a single significant flaw in the work, which is excusable and redeemable. Far too often the discounting in the chapters is done over a flat interest rate curve. While the term structure of interest rates is covered, and historical term structures and parallel shifts and steepening and flattening is covered in isolation in a thorough chapter and with wonderful data files, the necessity and explicit connection of discounting from an appropriate yield curve is left implied and only mentioned in a few exercises. I would have preferred a "round up" chapter where each of the subjects treated (bond discounting, portfolio expected returns, options, etc.) under a yield curve with advanced models. Sure BLOOMBERG and REUTERS have these sort of things (often incorrectly) programmed, but students need to learn explicitly about them and do the exercise themselves to comprehend the importance of curve discounting.
The CD attached in the back of the book is alone worth the price, with over two score of models that are practical and adaptable for students and professionals alike. The files are stored and separated according to chapters and subject matter. Each file has logical progression of the concepts advanced in the book, and each separate sheet either stands alone or appropriately links to data and models on other sheets, so editing for your own purposes is a breeze.
For those who want to train themselves in Finance (not "personal finance") then I suggest reading Copeland, Weston, & Shastri's Financial Theory and Corporate Policy (4th Edition) and Brealey, Myers, and Marcus's "Corporate Finance" and "Investments" followed by working through FM3. Such a course would give any self-disciplined person the equivalent of a Masters of Science in Finance.
Full disclosure: I am thanked in the "Acknowledgements" for providing a few helpful comments on the second edition.
