Entertaining

Book was more than I expected. Tied in many stories dating back to the early 1900's and the beginning of AT&T. Excellent read, very entertaining and well researched.
It takes exceptionally smart people to make truly massive blunders 2008-06-25
This book is a concise look at the evolution of formal investment theory, with continual contextual references to its ties to gambling and to organized crime. It also is a hilarious and insightful history of gambling from the Bernoulli's in the 1700s through the hedge fund traders of the late 1990's.
The author devotes over 50 pages to notes and the index. This was appreciated since I wanted to look up more about so many of the anecdotes he included.
Mr. Poundstone poignantly describes the downfall of high-flying firms such as LTCM, where the investment wizards went from the darlings of Wall Street to the dredges of the investment community in large part because they were so clever; and they started to believe they were infallible.
One LTCM road-show presentation was held at the insurance company Conseco in Indianapolis. Andrew Chow, a Conseco derivatives trader, interrupted Scholes. "There aren't that many opportunities," Chow objected. "You can't make that kind of money in Treasury markets."
Scholes snapped: "You're the reason - because of fools like you we can." (Page 281)
Warren Buffett marveled at how "ten or 15 guys with an average IQ of maybe 170" could get themselves "into a position where they can lose all their money." That was much the sentiment of Daniel Bernoulli, way back in 1738, when he wrote: "A man who risks his entire fortune acts like a simpleton, however great may be the possible gain." (Page 291)
He also points out the real world flaws in some theoretically appealing scams. The St. Petersburg Wager seems mathematically correct; yet it overlooks a vitally important constraint (pages 182-184). Another is the unfounded weight we unconsciously give to historical returns, as evidenced by his retelling of another Warren Buffett story:
In a 1984 speech, Buffett asked his listeners to imagine that all 215 million Americans pair off and bet a dollar on the outcome of a coin toss. The one who calls the toss incorrectly is eliminated and pays his dollar to the one who was correct.
The next day, the winners pair off and play the same game with each other, each now betting $2. Losers are eliminated and that day's winners end up with $4. The game continues with a new toss at doubled stakes each day. After twenty tosses, 215 people will be left in the game. Each will have over a million dollars.
According to Buffett, some of these people will write books on their methods: "How I Turned a Dollar into a Million in Twenty Days Working Thirty Seconds a Morning." Some will badger ivory-tower economists who say it can't be done: "If it can't be done, why are there 215 us?" "Then some business school professor will probably be rude enough to bring up the fact that if 215 million orangutans had engaged in a similar exercise, the result would be the same - 215 egotistical orangutans with 20 straight winning flips." (Page 314)
The author follows the lives of a few major contributors to investment theory, information theory, and betting theory: Claude Shannon, who invented Information Theory and paved the way for the digital computer age; John Kelly, who developed the formula for gains with no possibility of ruin; and Edward Thorpe, who built upon these findings and beat the roulette wheels, the blackjack tables and the investment fund managers.
It's a fast read - only 329 pages before the notes and index. I highly recommend it!
Interesting review of the systems of the past 
2008-06-09
This is a nice look into the past systems of betting. Also nicely written and gives a good understanding of the Kelly formula. Was not quite what I thought it would be but was a nice book.
OK, but not great

Having just finished Poundstone's book on Gaming the Vote, I was hoping for a book equally as interesting. Although this book was worth reading, and there are a few aspects from it that I will put into practice, I did not walk away wanting to quote it on a regular basis like I did Gaming the Vote.
It gives an interesting historical overview of various scientists involved with gambling and the stock market, and it reviews the concepts involved. These parts were interesting, but truthfully not fascinating.
The sections about Murder Inc, Boesky, Millken, and the junk bond collapse were much more interesting.
In short, it is an interesting book and worth reading, but there are many other books I'd read first...
Any investor or gambler needs this book! 2008-05-12
An insightful look under the hood at the factors affecting the money making process.
With a lot of very interesting stories, from the mob all the way to Nobel prize winners on Wall Street, it shows the latent traps that can destroy the bankroll of investors, gamblers, and poker players.
Any investor (or gambler) needs this book or he will risk losing his bankroll!
Fortune's Formula 2008-04-29
In 1956 two Bell Labs scientists discovered the scientific formula for getting rich. One was mathematician Claude Shannon, neurotic father of our digital age, whose genius is ranked with Einstein’s. The other was John L. Kelly Jr., a Texas-born, gun-toting physicist. Together they applied the science of information theory—the basis of computers and the Internet—to the problem of making as much money as possible, as fast as possible.
Shannon and MIT mathematician Edward O. Thorp took the “Kelly formula” to Las Vegas. It worked. They realized that there was even more money to be made in the stock market. Thorp used the Kelly system with his phenomenonally successful hedge fund, Princeton-Newport Partners. Shannon became a successful investor, too, topping even Warren Buffett’s rate of return. Fortune’s Formula traces how the Kelly formula sparked controversy even as it made fortunes at racetracks, casinos, and trading desks. It reveals the dark side of this alluring scheme, which is founded on exploiting an insider’s edge.
Shannon believed it was possible for a smart investor to beat the market—and Fortune’s Formula will convince you that he was right.

This is a really great book that I don't think many people have read. I am not particularly good at math, and I don't really gamble, but this book on the mathematics of odds is one of my favorite kinds of books - its smart, playful and full of an eccentric mix of gangsters, MIT professors and business people who have used a variety of methods to get rich by playing the odds.
If you have any interest in how markets or gambling work this is worth checking out.
The Original Quant... 2007-12-28
Ed Thorpe wrote "Beat the Dealer", and when he was kicked out of every casino in Nevada, went back to the drawing board. After he wrote "Beat the Market", finance in *practice* was never the same.
This is a fascinating account of the evolution of probabilistic approaches to money management, first in blackjack card counting, then in the stock market. Written in Poundstone's detailed style, every chapter draws you in further. A large number of interviews were conducted to put this together, and the anecdotes give it the color to make the story tingle.
Jim Simons and Renassaince Capital are cut directly from this cloth.
Engaging read, some good introductory concepts. 2007-12-21
This book is relatively well written and an interesting read, for many it will be an introduction to John Kelly, Claude Shannon, Ed Thorp and some of the other people whose career/investment histories are related in the book. This book is not a guide for the serious practitioner (nor does it pretend to be), but rather a relatively well written popular history. Its one drawback is that the author occassionally gets relatively excited about something and bludgeons the point home repeatedly.

This truly is an excellent work by the author. I found it to be extremely entertaining. The stories are fascinating for anyone of any background due to the author's talent and skill.
