Product Description

From the Back Cover

“Read this book before you invest a penny in the stock market.”
—Mark Cuban, Owner, Dallas Mavericks

“In one of the most memorable scenes in motion picture history, before giving him the  red pill, Morpheus says to Neo, ‘You’re here because you know something. What you know, you can’t explain, but you feel it. You’ve felt it your entire life—that there’s something wrong with the world. You don’t know what it is, but it’s there, like a splinter in your mind, driving you mad.’ Although Arnuk and Saluzzi will not expose every dark corner of the ‘matrix’ that our capital markets have become, they will provide the clues to aid you in your quest to understanding  just why more people withdraw from trading fully aware that ‘there’s something wrong.’  Morpheus also asks, ‘Do you want to know what it is?’ To all who answer yes  and take the red pill, read this book.”
—Tyler Durden, Zero Hedge

“Markets now trade at the speed of light, apparently benefiting Wall Street ultra-short-term traders over long-term investors and causing more than a few ‘flash crashes’ along the way. Arnuk and Saluzzi intuitively piece together how High Frequency Trading, for-profit exchanges, fragmentation, regulatory changes, and a ‘need for speed’ over the past 20 years have  dramatically shifted benefits from investors to short-term traders in our increasingly fragile  markets. A must read for anyone concerned about investors, trading, and  the long-term health of U.S. stock markets.”
—Professor Michael Goldstein, Professor, Finance, Babson College

“Arnuk and Saluzzi are the Woodward and Bernstein of the securities markets.  Their gutsy, dogged sleuthing exposed the perverse market effects of robotic trading  and predicted an event like the Flash Crash 2010, long before blinkered market regulators had a clue. The two crusaders deserve a medal for looking out for investors.”
—Jim McTague, Washington Editor, Barron’s

“Who broke the stock market? The NYSE and NASDAQ, that’s who. They sold the investing public down the river so colocated algo driven servers of  high frequency traders could steal billions by front running grandma’s mutual fund.  The horrific truth about this legalized theft is all here in black and white.  Read it, and you will never so much as invest one thin dime in U.S. equities again.”
—Barry Ritholtz, CEO, FusionIQ; Author, Bailout Nation and  The Big Picture website; Bloomberg personality

“The authors explain in wonderfully clear language how, instead of banning card counters as they do in Vegas, Wall Street has remade itself to not only stack the deck in the card counters’ favor, but to enable them to do so via ever-faster computer networks and algorithms, that leave not only ordinary investors but many sizable institutions, like pension funds, with worse odds than on a lottery ticket. There’s more, much more, in Arnuk and Saluzzi’s book; it’s quite simply a must read, if you care about your capital—or the future of our capitalist economy.”
—Kate Welling, Former Founder, Editor, and Publisher, Weeden & Co. LP, Welling@Weeden; Former Managing Editor, Barron’s

An eye-opening view on the way stocks are really traded today—and why the stock markets are  broken and desperately need to be fixed. Written in an easily understandable style, the authors explain:
• The strategies and tactics high frequency  traders use to scalp pennies off of nearly every retail and institutional share traded
• How the stock exchanges provides high frequency traders with powerful tools that give them an advantage over retail and institutional investors
• Why the stock markets no longer accurately price the values of the securities in your portfolio
• What you can do to prevent these and other problems from getting any worse
Authored by the Wall Street traders who figured out how high frequency traders were harming retail and institutional investors and explained how it all works on 60 Minutes, Bloomberg TV, CNBC, and  Fox Business News

Learn
• Why retail investors are pulling their money  out of stocks in unprecedented amounts
• How decades of regulation created the  broken markets we have today
• Why there are more than 40 exchanges,  sub-exchanges, and dark pools rife with  conflicts of interest where stocks  are traded today
• How the stock exchanges became for-profit companies and fundamentally changed market structure
• Why the Flash Crash happened—and why  it will happen again
• How there are two markets—the fast,  accurate one that high frequency traders  see and the slower one that retail and  institutional investors see

Difficult but Important Work Nov. 8 2012
By Greg Nyquist - Published on Amazon.com
Format: Hardcover Vine Customer Review of Free Product
This is a very important book dealing with a subject that many people find baffling. Nowadays financial markets have become so complex that it is nearly impossible for an outsider to grasp how they work. Sal Arnuk and Joseph Saluzzi try their best to reduce this complexity to terms comprehensible to the layman; but in the end it's almost a quixotic venture. If you know little of financial markets you might find "Broken Markets" difficult to follow. But the Arnuk's and Saluzzi's thesis is not all that complex. The authors argue that our financial markets are thoroughly broken. They explain how stock exchanges have been taken over by high frequency traders who use sophisticated computer algorithms to scalp pennies off nearly every share traded. This has essentially transformed stock exchanges from facilitators of capital formation to arbitrage driven casinos that are rigged in favor of a class of speculators, the high frequency traders, who account for 50 to 70 percent of the volume traded on stock exchanges and, still more ominously, 80% of the profits.

It's hard to see why anyone, after going through this book, would want to have anything to do with stock market investing. To be sure, the intention of the authors is not to scare investors away, but to motivate investors to demand reform. I'm not sure whether the specific reforms advanced in the book are either politically feasible or will actually cure the ills of hyper frequency trading. There are a number of other problems afflicting asset markets other than those limned by Arnuk and Saluzzi in "Broken Markets"; and their doesn't seem to be much interest in even comprehending, let alone tackling, these issues. Curiously, the authors of Broken Markets trace the rise of high frequency trading, not to deregulation, but to misregulation. But if this is true, how can we be sure that attempts to reregulate won't lead to an even greater disaster? We seem to be suffering from a failure of leadership in such matters. Hopefully, this book will help turns thing around and bring a bit more intelligence and wisdom to the whole issue of regulating and improving free and open markets.

Read the book....don't wait for the Movie June 25 2012
By James J. Biancamano - Published on Amazon.com
Format: Hardcover
I have been following the (meandering at times) thoughts and opinions of Sal Arnuk and Joe Saluzzi for a number of years. The guys at Themis have become thought leaders on market structure, and while for some it may be easy to disagree with their opinions, it is very hard to ignore them. I will be quite frank and say that there are quite a few issues that I differ with them on, but that's no reason for me or anyone else to have a negative opinion of this book. The book itself is not meant to be read at one sitting, it is a much easier read taken in small doses. The authors are outspoken, passionate, and right or wrong willing to take a stand on issues that too many in our industry either ignore, or afraid to speak about. Market volume is down nearly 50%, something is wrong and the authors are giving their POV. They made me question some of my own opinions, and for that alone it is worth the four star review.

One of the reasons to read this book, especially if you have witnessed the events and turmoil of the last few years, is to understand just how we have gotten to this point. Yes it focuses on HFT, but HFT is now probably more than 90% of the volume on any given day in the Equities markets. While not perfectly organized, since it covers quite a bit of ground, it still gives a good accounting of the history of the Equities Industry in the last 10-15 years. Yes it is an "insider's view" but that exactly what this subject needs. While not written as a narrative like Scott Patterson's "Dark Pools", it still manages to tell an interesting and compelling story with enough facts for the reader to understand what the flaws are and what can be done. Of all the numerous topics it tries to cover it is especially detailed when discussing the rise of HFT and Dark Pools. It's very hard to write something interesting about Exchange demutualization, Co-location, Reg NMS, Reg ATS, et al, but since the authors pull no punches, it makes for some very enjoyable reading.

The real reason to read this book is because the authors actually go out on a limb and offer solutions. Are all those solutions the right ones? Far from it, but I'd rather hear someone offer even the most ridiculous solution than offer nothing at all. It is thought provoking, informative and very entertaining. There are many people in our industry that have jumped on the anti-HFT bandwagon (and let me say for the record I don't think Sal and Joe are altogether anti-HFT) for nothing more than self serving reasons without offering real solutions; you don't get that feeling here. It is actually an enjoyable read with enough anecdotes to keep it from being tedious. It leaves the reader, especially anyone who has a very limited understanding of the equities markets armed with enough information to investigate further, and that is exactly what the authors want you to do.

informative and thought provoking, could be better organized May 23 2012
By Nim Sudo - Published on Amazon.com
Format: Hardcover Vine Customer Review of Free Product
Have you ever done something like the following: you place an order to buy a stock at $15.00, and your order is filled at $14.99999? The answer, which I learned from this book, is that you have just unknowingly traded with a high frequency trading (HFT) algorithm. My understanding (although the book doesn't explain this so clearly) is that something like the following happens: a (human) seller offers to sell the stock at $15.00. The computer, which is located in the same building as the computers that run the stock exchange and so has access to huge amounts of information that you don't at enormous speed, decides based on order flow that the stock is headed downward in the next few seconds and that you were an idiot to buy it (in the very short term). So the computer jumps in front of the seller, winning the auction by .001 cent per share. The human seller hasn't yet sold the stock and so may need to lower their price. This can then help the stock's price decline (in the very short-term), and the computer can then buy shares to cover the ones that it sold to you and make a profit of a couple of pennies per share. HFT algorithms do this kind of thing hundreds of millions of times a day and make billions of dollars a year. They also rapidly enter and cancel huge numbers of orders in an attempt to manipulate prices in their favor, making short term prices impenetrable and good order execution difficult for human investors.

This book passionately argues that our markets are broken as a result of HFT algorithms and the unfair conditions in which they operate. My summary of the argument as I understood it is as follows: In the "old days", the stock market was kept going by (human) market makers and specialists, who provided liquidity (i.e. being willing to buy or sell something when no one else was) and smoothing out fluctuations (e.g. by matching up large buy and sell orders). They profited from substantial spreads (e.g. bid and offer prices might be required to differ by intervals of 1/8 of a dollar), in addition to the privileged information they had. Then new regulations were introduced which allowed stocks to trade in intervals of a penny and which enabled fast electronic trading. While these nominally helped small investors by reducing spreads and taking out the middleman, they counterintuitively made things worse by causing market makers and specialists to be replaced by HFT algorithms. The HFT algorithms skim roughly as much money from the markets as the market makers and specialists used to, but without providing the same services. In particular, while the large number of high frequency trades nominally provides liquidity, when things get bad the HFT firms can simply shut down the computers and bail, as happened in the "flash crash" of May 6, 2010, when stock prices dropped a huge amount for no fundamental reason and then rebounded, all within minutes. In addition HFT makes it difficult for mutual funds that need to make large trades. Although a large trade can be broken into small chunks, HFT algorithms can sense that this is being done (with the help of information which they really shouldn't have access to) and work to move prices against you.

In addition to all of the above, there are some serious conflicts of interest and lack of transparency. Many trades are executed in one of dozens of "dark pools" whose activity does not appear in ordinary listings. A brokerage can choose among these venues to execute your order in a way which minimizes their cost of execution but which does not necessarily give you the best price. Data about your every move can be sold to HFT firms which will use it against you. HFT firms buy "colocation" (i.e. the right to place their computers in the same building as the stock exchange computers). This means that the stock exchange, instead of working to make a level playing field for all participants, is selling advantageous conditions to those that can afford the fee (as well as the necessary high tech).

I would give the book five stars for being thought provoking and informative (even though I was not convinced by all of the arguments). I am deducting a star for suboptimal organization. The book repeats the things that the authors are upset about a lot, but does not give a very clear and organized explanation of the basic facts, with interruptions for biographical interludes, and more repetition. It reads as if a collection of related blog postings were edited into a book. This is made worse by the inclusion of three guest chapters by other authors; while the guest chapters are well written by themselves (although I found their arguments more extreme and less convincing than those of the main two authors), they further repeated many of the same points. There are also appendices with "white papers" by the authors, but I didn't read them because I didn't want to hear the same stuff again (although maybe it is more clearly explained there).

Some of the arguments didn't quite convince me. For example, the "dark pools" originated as places for large orders (e.g. by mutual funds) to trade quitely without moving prices a lot. Later they became dominated by HFT. The authors seem to feel that the lack of transparency in the dark pools is good when it helps the "good guys" (mutual funds managing your hard earned savings), and bad when it helps the "bad guys" (HFT firms which skim investor pennies and perform no social good). This seems inconsistent to me (although I don't have a better suggestion and I admittely know extremely little about this topic). The first two guest chapters argue that the "flash crash" was a huge catastrophe, but if you are a long term investor, then you probably didn't notice anything (unless you were unlucky enough to sell using a market order during those few minutes). The last guest chapter argues that the introduction of penny increments for stock prices caused the loss or lack of creation of 20 million American jobs. What? The argument is that the penny increments put market makers and specialists out of business, reducing the money available to financial firms to shepherd small IPO's into the marketplace, with a resulting lack of job creation. Well, maybe something is going on there, but I think there are some other significant factors for reduced IPO's and jobs, for example, so many IPO's introduced in the late 90's were such junk that no one wanted to invest in anything like that anymore, and our country is losing its lead in education and technology so that many of our jobs can be done by workers overseas who will do so for much less.

Anyway, at the end of the book there are a few suggestions for improving the situation. Meanwhile, happy reading, and don't use market orders.

Cards Stacked July 25 2012
By Ted Feit - Published on Amazon.com
Format: Hardcover Vine Customer Review of Free Product
When it came time for FDR to appoint the first chairman of the Securities and Exchange Commission, he selected Joseph P. Kennedy, a well-known stock market operator and speculator, presumably on the theory "it takes one to know one." Well, it was a good choice, and the SEC got off to a good start, its reputation and effectiveness not only lasting, but increasing for several decades. Unfortunately, in the last 10 years or so, this has not been the case, as theoretical economists and attorneys have led the regulator far afield from protecting investors, the original intent of the '33 and '34 Acts.

As a result many new rules have been instituted changing the investment climate, and this treatise indicts many of them, especially what has become known as high frequency trading ("HFT"), a method that allows "front running," something that was always illegal. The authors, two well-known institutional traders, have been conducting a long-standing effort to do something about the practice for several years. Their contention, of course, is that HFT is destroying investor confidence and portfolios, in general, by allowing these practioners to scalp trades with advance order knowledge and steal (often literally) pennies which mount up to millions of dollars.

It should be noted that conflicts of interest have always been present on Wall Street: Was the broker who sold you that stock acting in your or his best interest? But generally, the markets worked, companies were able to raise money, the public could amass stocks for savings and retirement. At present, however, the authors contend that this is not the case, especially when the very institutions (the SEC, NYSE, NASDAQ and other regulators) are more interested in profits and speed and volume than in the orderly markets of the past.

Read it and weep.

Recommended.

Interesting and informative book on HFT. July 30 2014
By Ting Liu - Published on Amazon.com
Format: Paperback
I have read this book from cover to cover through my workplace's safari online book account and found this book is very informative, and also quite relevant to the current market. Though I work for fixed income side, many of the discussions are and will be relevant very soon.

The author has first described main ideas about how dark pool and HFT works, presented a number of issues such as liquidity-maker rebate program, private data feed, flash orders, co-location, and then discuss various HFT strategies that might hurt the traditional market maker and regular investor. It gives very clear and simple examples that everyone can easily understand. More interestingly, it also points out many technical details such as ITCH API which leaks hidden order information. Even if you happen to work with these API in your daily work but never really pay attention to these rarely used features, you will find his discussion has widened your view.

In addition to this book, I have also read Michael Lewis' Flash Boys which also discusses HFT and dark pool, and is a popular book at the moment. Unfortunately, Michael's book is a story full of non-important and trivial details. I have to filter out all the junkies to get to the meat part of the Michael 's book which can be simply summarized in about five sentences. Its short version can be freely found on NY Times web site:

http://www.nytimes.com/2014/04/06/magazine/flash-boys-michael-lewis.html?_r=1

This book, on the contrarily, covers everything that Flash boy covers and adds a lot more technical and regulatory details. More importantly, this book is written by someone who has first hand experiences in market structure. Moreover, the author's writing style is very concise and the concepts are presented in a logic way which makes the reading enjoyable.

However, the book is very opinionated and hence I gave the book 4 star though I am against HFT and share the same view point of author. I just think as a book it should be more objective when presenting information.
