Saturday Morning Essay: Book Review, Michael Lewis and "Flash Boys"
While HFT takes many forms, all of it is based on a couple of simple principles: First, powerful computers using algorithms can execute trades at lightning speed; and second, one can gain enough of an advantage over other investors through sheer proximity to the stock exchanges, even when one is dealing with communication speeds nearing the speed of light, to game the system.
The proprietary trading departments (prop trading) of the big Wall Street banks, the hedge funds, the bucket shops specializing in HFT, all do it. They all cheat by using HFT. As a result, HFT investors can take the risk out of investing and can report strings of profitable investing days running into the thousands, as many of them have. HFT investing acts, in essence, as a kind of tax on the world of finance, a tax extracted at the rate of a fraction of a penny at a time, repeated millions of times each day (this is the "high frequency" of high-frequency trading), money earned simply by gaming the system so the HFT player cannot lose.
Michael Lewis gives many examples of how it's done, but a systems analysis involves these key elements.
1. Under what is known as Regulation NMS, passed in 2007, a broker-dealer licensed by the Securities & Exchange Commission (SEC), when given an order to buy or sell stock by a customer, must search the available exchanges to find the NBBO, the national best buy or offer. In other words, the broker-dealer (a company like Paine Webber, when there used to be a Painer Webber and people would stop what they were doing, like stealing home, to listen to them) must seek to execute the order on the best terms available.
2. It is critical to understand that the world of stock exchanges in America has fragmented over the years into about 16 different and discrete exchanges, mostly located in New Jersey on the far side of the George Washington Bridge. The New York Stock Exchange that serves as a backdrop for the CNBC show, for example, is mainly a stage set. The actual trading is done by a computer server in a large room on the west side of the Hudson River. This is also the case for the other exchanges: stacks of electronic boxes in large, mostly empty rooms, scattered around New Jersey. There are no "trading pits" where buyers scream out orders to a guy in a colored jacket feverishly scribbling confirmation notes and thrusting them at the reaching hands. That's the old way. The new way is the silent flow of electrons through circuit boards, executing trades in microseconds, over and over, all day long.
3. The Flash Boys (well-financed Wall Street Banks and hedge funds) bribe the various exchanges (the NYSE, NASDAQ, Direct Edge, various others) to allow them to "co-locate" their electronic connections immediately adjacent to the stacks of computer boxes comprising the exchange. They pay a lot of money for the privilege. Thus, a communication from an HFT "trader" only has to travel a few feet on fiber optic cable to hit the exchange. This tiny advantage in speed makes all the difference. A trading floor on Wall Street might reach the exchange in 3 or 4 milliseconds (3 or 4 one-thousandths of a second). To get a sense of this duration, the blink of a human eye takes a little under 100 milliseconds to complete.
4. If, for example, a trader on the prop floor of the Royal Canadian Bank (RCB, where Michael Lewis's hero, Brad Katsuyama worked) receives an order to buy 1,000 shares of Procter & Gamble at a price not to exceed $80.05 (a limit order, as most purchasing is done), RCB submits the order on its "slow" 3 or 4 millisecond connection. Finding 1,000 shares of P&G for sale might involve a search among numerous exchanges, since SEC rules now allow multiple exchanges to sell the same stocks. The HFT trader exploits this environment by using its connections, which transmit data to the exchanges in microseconds (millionths of a second). The HFT trader "sees" the RCB limit order, then "front-runs" the order by instantaneously searching the exchanges for a buy at less than the limit order price of $80.05, completes that transaction, and then sells the P&G stock to the RCB trader. The HFT trader might make a penny a share or less, or ten bucks minus transaction costs, on the whole deal; but scaled up into a full day of trading, where such scams are repeated millions of times a day, it becomes real money. In effect, the HFT trader is an uninvited middleman standing between a seller and a buyer and taking from both.
This is but one form of differential "arbitrage" used by HFT algorithms. There are numerous others, limited only by the imagination of the mathematics Ph.D's and computer programmers who comprise the money-making wings of the big U.S. banks and hedge funds.
As noted, Michael Lewis tells the story from the vantage point of Brad Katsuyama, a Japanese-Canadian who worked for RCB, got fed up with HFT tactics, and started his own exchange, the Investor's Exchange (IEX), designed to foil HFT tactics. Whether it will work in the long run or not remains to be seen. It IS interesting that contemporaneous with the roll-out of the book, and the renewed focus on HFT brought by the book, the stock market has softened and headed south (even Attorney General Eric "Place" Holder has apparently been jostled out of his customary coma and now vows an "investigation" of a practice which has been the dominant force on Wall Street for five years). The largely illusory trading of HFT accounts for nearly SEVENTY percent of all investment activity on American stock exchanges, and the total volume of trades on the exchanges has doubled since about 2007, reflecting the "echo" transactions of the HFT players. It is a cash cow for the exchanges and for the scammers who run these investment games.
It might be difficult to overestimate the impact that a curtailment of HFT might have on the American economy generally. Our President, who never met a Fat Cat Banker he didn't like (and didn't shield from prosecution, such as the Great & Honorable Jon Corzine, formerly of MF Global), is either aware or has been told that he should be aware, that the old school method of investing, to buy stocks and hold them over time ("going long") has had its day, and that as with mortgage-backed securities and money printing by the Federal Reserve, financial scams comprise at least half of what appears to be purposeful economic activity in the United States. We might be left with only IPO issuances in social media stocks if this keeps up, and how many more hours do Americans really have left to waste on Facebook and Twitter?
Perhaps the wiser course is to cool out on the moralizing about HFT. Let Goldman Sachs, J.P. Morgan, Citadel, and the HFT shops in leafy Connecticut continue to game the system (which involves lots of foreign money, after all). Let them extract their toll of fractional pennies on every stock transaction. Let the rich get richer. They pay all the income taxes, after all, and always max out their FICA obligations. They provide the funding to the feds which allows all the vast hordes of Americans living on government assistance to keep their heads above water, to keep the SNAP cards topped off, to keep those S.S. checks coming, to receive those diabetes treatments as they wallow in their immense lipidinous carcasses in the trailer parks of Bullhead City. Noblesse oblige. What the rich are able to save from taxation they send offshore. That's okay too. It keeps "bankers" in the Cayman Islands in the market for late-model Benzes. It's all good. Let the Flash Boys have their fun. Brad Katsuyama, after all, was just a greedy bastard with a pang of conscience, or maybe a grudge against playahs who were scamming his trades. So he turned his IEX into his own money-making investment. He should have called it the BuzzKill Exchange, if you ask me. What's he going to do when the whole American investment edifice comes tumbling down around his ears, hmm? And what about Bullhead City?
Nice work, Michael Lewis. Good luck with your next book, when everybody's flat busted.

Saturday Morning Essay: Life on the New American Plantation
Brought to you by Trader Joe's Dark Roast as the Tropic of Capricorn takes a direct shot from the sun...
From ZeroHedge: "Blackstone Group appears to be trying to oligopolize the business of renting single-family homes in the U.S.. As Bloomberg reports, after the housing crash left more than 7 million foreclosed homes in its wake, the investment firm has spent more than $7.8 billion purchasing about 41,000 single-family homes for rental conversion. The world's largest private equity firm has quickly become the largest landlord (of rental homes) in the U.S. and in October, Blackstone offered the first-ever "rental-home-backed" security on Wall Street. One has to wonder if this was the plan all along?"
Interesting idea. My older brother predicted The Great Foreclosure many years back. Maybe this, indeed, was the plan all along. Certainly at the time the prediction was made it seemed vaguely paranoid, but I have come to see that paranoia is a perfectly reasonable adaptive attitude in a world dominated by private corporations. To wit, it is not paranoid to think that they do not have your interests at heart, because they don't. If you think they do, even for a moment, you've been watching way too many Jimmy Stewart movies.
Get the American hoi polloi to mortgage their houses to the moon with adjustable rate mortgages, pump the consumer economy with equity loans, then when it all pops, scoop up all the distressed properties for pennies on the dollar and rent them to the people who used to own them. As a wise man once said, you'll never go broke underestimating the intelligence of the American people.
Calling this latest grift a "plan" might be a little too grand. Capitalism simply seeks profit "opportunities." Regarding Blackstone's raptor-like feeding frenzy as part of a conspiracy may be an example of the "ant in the sandbox" fallacy suggested by the polymath Herbert Simon decades ago; to wit, if you examine the path of an ant across a sand box, you will be impressed with the clever, efficient way he traversed the hills and valleys to follow a fairly straight line. When, in fact, all the ant was doing at every stage was making a choice to go left, right, over or down the terrain.
So it is with the Great Foreclosure. The Robber Barons got rich on fraudulent mortgage products, and now they're assembling new fraudulent Rent Backed Securities (RBS - that's even a good logo for Robber Barons) out of the wreckage. What else are they supposed to do? They're here to make money. L'argent, c'est moi.
At least someone is still getting rich in this country, something increasingly difficult for the ordinary member of the Booboisie. Blackstone and other financial predators are helped enormously by the Federal Reserve's policy of "exceptionally low interest rates for the foreseeable future." If you're big enough to borrow for practically nothing; then buy a house in Florida, say, for $100 k; then rent that 2/2 with lanai charmer for $900/month, annual income of $10,800; then even with a 10% management fee, your gross cap rate is around 10% a year. Bet you can't get that on your B of A money market, can you? Now if you're like Blackstone and can do this scam 41, 000 more times, you've got yourself a nice little business going. And you can build on that by bringing in investors on whom to pawn off the whole operation, pay them a nice 6% on their money, pocket 4% for having the brilliance (and corrupt connections) to pull this caper off, and essentially have no skin in the game. And then when the economy finally and completely collapses, maybe from an attack of acute nausea, Blackrock can let someone else hold the bag. Probably us again!
Sweet. It's the modern version of a sharecropper's life on the plantation, in a way, and it's what's left to the middle class now that the economy has been completely hollowed out by our decision to globalize and become an "open economy," as the Plantation Liberal Economists have always urged. As Gail Tverberg notes in her latest insightful post,
Economists, through their wholehearted endorsement of globalization, have pushed industrialized countries into a competitive situation which we are certain to lose. While oil prices tend to push wages down, competition with Asian countries makes the downward push on wages even greater. These lower wages are part of what are pushing us toward collapse.
I wonder to whom Gail could be referring? Well, this isn't a "Science" post so I certainly won't mention any names. Globalization and hyper-specialization of the economy, all guided by ruthless capitalism, are the status quo here on the Plantation, and Plantation Liberals always work within the status quo. If your specialized occupation, like assembling auto generators at a plant in Indiana, went away to a warmer clime where the workers aren't so fussy about "benefits," then you're just going to have to learn to do something else, such as Planning or Tanning, admittedly at a lower rate of compensation.
Maybe more "transfer payments" will help the new tenants to pay their new landlord. We can always print the money to send more cash to the poor to keep them in the houses as tenants which they used to own. And I'm sure Blackstone (probably a description of the company CEO's heart) will be reasonable and charitable lessors. Just get through the credit check, deposit the four months of rent, and pledge your youngest child as a security deposit. And if it doesn't work out, as a free gift to all applicants, a large cardboard box and map to the closest bridge.

Austerity, Then & Now
At a very personal, selfish level, I don't really care how "austere" the government decides to become. I don't have any real skin in the game, other than the increasingly perilous adventure of trying to drive on California's potholed roads. America doesn't really have any public amenities which are threatened by greater austerity; for example, we don't have a real passenger rail system, or much of anything in the way of public transportation. The conditions of accommodations and facilities (bathrooms, etc.) in national and state parks are usually a complete disgrace, and so forth. The graffiti-strewn walls, the urban blight, the shitty, cheap, tawdry look of so much of what's been built in this country in the last 60 years, are all reflections of the people who live here, their aesthetic criteria, their social mores. It's how we live and we've all gotten used to it. The public realm in general in the United States is a vast wasteland, in fact, and is the emblem of our governing ethos; to wit, beauty and grace in life are "private virtues" which must be earned and purchased. You must amass enough money to buy your own sylvan enclave, or your house on the beach, in order to escape the crapscape (h/t: James Kunstler) of American life in general. Amazingly, the financial elites who own such an overwhelmingly large proportion of the wealth in this country, and can afford to insulate themselves from the trash heap, have enlisted the help of the some of the most disadvantaged (the Tea Party types and Southern Rednecks, not always the same people) to assist them in enforcing this way of doing things. Thus, the Tea Party has as one of its main platform planks the perpetuation of the "Bush tax cuts," as if such a top-margin benefit could possibly help them at all.

The Cargo Cult Economic Recovery Under the Rahm Emanuel Administration
Sometimes I say to myself, "Self (for I want to get my attention), what's the deal with this Obama Administration? Why is it setting the table for the Tea Party?" I'm willing, you see, to ask myself the tough questions. Others may dodge them, but in the privacy of my own mind, I follow the facts where they lead.

Wile E. Updates His Dow Projections
Yes, yes, I know. It was my finest hour, when I predicted a Dow fall to 9,100 when the NYSE was cooking along at about 14,000. Yet Krugman got the Nobel for Economics. Go figure. What's he ever been right about? Well, I won the Nobel Prize of My Mind, which, unfortunately, does not come with a large honorarium and a trip to Stockholm.

Sure, things can get worse
I remain in continual awe of "Tyler Durden" at the zerohedge econoblog, who is an amazingly fecund and trenchant analyst (pretty good adjectives, huh?) of the American economic and financial market scene. Durden (his nom de blogue borrowed from the main character in "Fight Club") does not simply repeat the same tired stats one can read everywhere, e.g., the American economy is 70% consumer spending, we borrow a lot from China, et cetera. By now everyone knows that stuff, and yet blogsters like Jim Kunstler simply use those stats over and over, dressing up the doomsaying with artistic, novelistic writing (entertaining, to be sure) and leave you about where you started.

Audit the Fed?
Friday's Happy Face entry was, I guess, somewhat satirical. Actually, I simply do not see how the United States economy can recover in anything under a decade or so. The interesting part for me is the study of the various components, or shells, under which the Powers That Be are hiding the grim truth from their subjects. In this regard, the "Audit the Fed!" Brigade forming in Congress strikes me as a kind of Suicide Cult. It's borderline treason, in fact, for otherwise estimable pols like Ron Paul to suggest we really, really ought to kick over the slimy rock called the Federal Reserve Bank and see what slithers out. I'm pretty sure we don't want to know.

The Casino at the End of the Universe
I have referred before to a remarkably prescient book, published some years back, entitled Infectious Greed by Frank Partnoy, which detailed the tenuous world of derivatives and the threat they posed to the world's financial stability. Partnoy took as a jumping-off place the meltdown of Long-Term Capital Management, that giant hedge fund quietly working its sinister magic in the sylvan quiet of the Connecticut suburbs. LTCM innovated like crazy and had the inspiration, and genius, of sensing it required the services not of standard issue MBAs, but of math PhDs from MIT and Harvard who could construct the arcane and insanely complicated algorithms necessary for LTCM to optimize its computer-driven arbitrage strategies. The system couldn't miss, until it missed entirely.
