Broken Markets: How High Frequency Trading and Predatory Practices on Wall Street Are Destroying Investor Confidence and Your Portfolio by Sal Arnuk, Joseph Saluzzi

It was not due to small supply and rabid demand. One algorithm was pricing the book at 1.27 times the price of the other algorithm, which in turn would revise its price to 0.998 times the price of the first algorithm, creating a positive feedback loop. Momentum ignition is extremely damaging to long-term investors. It does not cost pennies; it costs them quarters, and it ferociously distorts the price discovery process. How the World Began to Learn About HFT While HFT has been steadily expanding since the millennium and exponentially since the implementation of the SEC’s Reg NMS in 2007, it stayed out of the mainstream media until mid-2009. Over the July 4 weekend, Sergey Aleynikov was arrested by the FBI at Newark Airport for stealing code from his prior employer, Goldman Sachs, and trying to bring it to his new job as an HFT programmer at Teza Technologies, where he was set to triple his $400,000 salary.

The proposals called for dark pool indications of interest to be treated like regular quotes and therefore required to be visible to all investors; real time disclosure of the identity of the dark pool that executed a trade; and any dark pool that traded more than 0.25% of a stock had to display those orders in the public quote.8, 9 Ironically, Reg ATS in 1998 was supposed to force more orders into the public quote to aid in the price discovery process. However, it resulted in almost one-third of orders being executed away from the public quote and in dark pools. With the flash order and dark pool proposals, it appeared that the SEC was serious about increasing transparency. The SEC received hundreds of comment letters, most by industry participants who wanted to maintain the status quo. Unfortunately, even though proposed in 2009, the SEC has yet to approve any parts of either proposal.

Investors who thought they were protecting themselves with the prudent use of stop orders were left with fills that were far away from the closing price. Today’s severe market drop should never have happened. The U.S. equity market had been hailed as the best, most liquid market in the world. The market action of May 6 has demonstrated that our equity market has major systemic risks built into it. There was a time today when folks didn’t know the true price and value of a stock. The price discovery process ceased to exist. High frequency firms have always insisted that their mini-scalping activities stabilized markets and provided liquidity, and on May 6 they just shut down. Money began pouring out of the equity market, as nervous investors lost confidence. The SEC responded almost five months later, issuing a report titled “Findings Regarding Market Events of May 6, 2010.” The report placed a good piece of blame on one midwestern money manager.

Overall, dark pools and broker internalization facilities aren’t unquestionably bad, but it’s hard to make a compelling case for any significant benefit. For professionals in particular, they make it easier to shoot oneself in the foot. For the public, the lack of transparency doesn’t inspire confidence. And for the markets themselves, there is a legitimate question about whether or not they detract from the price discovery process. For these reasons, I believe that the default destination for retail customer orders should always be the public markets. If customers want to “opt in” and select a dark pool or internalizer for their orders, that’s fine, but it should be a choice the customer makes – not a choice that the broker makes for them. The Impossibility of Getting Full and Precise Information Lewis, now embedded in the offices of IEX, walks us through a discussion of how IEX might provide information to the customers of the banks about how the banks and IEX handle their orders.

Prior to early 2001, stock prices in the United States were quoted in multiples of one-sixteenth and one-eighteenth of a penny. Since April 9, 2001, all U.S. stocks have been quoted in decimals. This seemingly innocuous change has had a dramatic impact on the market structure, which is particularly negative for the profitability of statistical arbitrage strategies. The reason for this may be worthy of a book unto itself. In a nutshell, decimalization reduces frictions in the price discovery process, while statistical arbitrageurs mostly act as market makers and derive their profits from frictions and inefficiencies in this process. (This is the explanation given by Dr. Andrew Sterge in a Columbia University financial engineering seminar titled “Where Have All the Stat Arb Profits Gone?” in January 2008. Other industry practitioners have made the same point to me in private conversations.)

He gives the broker an order to buy 100,000 shares of Acme Corporation. It doesn’t matter if it is a mutual fund, registered investment adviser (RIA), or a hedge fund, the point is that when dealing with a pool of money, the trades get big. This affects your money regardless of whether you own individual stocks or pool it with a manager. The market doesn’t care who you are. Now we enter the point of price discovery. price discovery The process of determining the price of an asset in the marketplace through the interactions of buyers and sellers. Also known as reality versus what you think a security is worth. You may discover that nobody wants to buy your stock unless the price is very low. Or, you may discover that in order to buy a stock you must pay a premium to get someone to sell it to you. market maker A dying breed.

Investors ran away from securities that made them nervous—driving the current yield of 30-day ABCP up to 6 percent (from 5.28 percent in mid-July)—and began to accumulate Treasury bonds and notes, long the safest securities on the planet. This classic flight-to-quality nearly resulted in a failed auction of four-week bills on August 21, when massive demand for government paper so muddied the price discovery process that, ironically, some dealers pulled back from bidding to avoid potential losses. As a result, there were barely enough bids to cover the auction, so yields shot up despite the strong real demand. Karthik Ramanathan, head of Treasury’s Office of Debt Management, had to reassure global investors that the problems stemmed from too much demand, not too little. In the end, the Treasury auctioned off $32 billion in four-week bills at a discount rate of 4.75 percent, nearly 2 percentage points higher than the prior day’s closing yield.

While the market price (shown by the dashed line) moves up as a result of the catalyst, it initially underreacts and therefore continues to go up for a while. A trend-following strategy buys the asset as a result of the initial upward price move and therefore capitalizes on the subsequent price increases. At this point in the life cycle, trend-following investors contribute to the speeding up of the price discovery process. Figure 12.1. Stylized plot of the life cycle of a trend. Source: Hurst, Ooi, and Pedersen (2013). Research has documented a number of behavioral tendencies and market frictions that lead to this initial underreaction:3 i. Anchor-and-insufficient-adjustment. People tend to anchor their views to historical data and adjust their views insufficiently to new information. ii. The disposition effect.

The Invisible Hands: Top Hedge Fund Traders on Bubbles, Crashes, and Real Money by Steven Drobny

Then they hide it through beta, sometimes through difficult-to-see exotic betas. Alpha seeking is, however, a positive sum game for society. You need to have people in there chasing alpha to make markets more efficient. And by efficiency I am not talking about providing liquidity to the market. Rather, you need to have people constantly trying to evaluate the right price, who are ready to trade on that belief, pushing the market towards equilibrium in a price discovery process. That way we get better allocation of resources in the real economy and fewer bubbles. If there had been more John Paulsons in the market during the last few years, and fewer gullible institutional investors in subprime, the global economy would have been much better off. But alpha in a strict sense is a zero-sum game, although with beneficial externalities for society. What else did you learn in 2008?

The quick and, indeed, instantaneous change in most prices that can be assumed in a model economy will communicate the facts quickly to everybody. The time and space for some consumers and some producers to err and to develop the patterns described above is very restricted in the context of pure models. However, the more we move away from the unrealistic model assumptions and consider a real-life economy, in which spending is not ongoing but discontinuous and intermittent, and price-discovery therefore periodic, these processes will be unavoidable. In any case, the imperfections of a real-life economy, when compared to the purity of the theoretical model, enhance the phenomena we just described; they do not cause them. What causes the processes described here is the lack of full transparency, which leads to potential misinterpretation. Some economic agents will confuse additional nominal spending with a rise in real demand that can only result from changes in consumer preferences or true entrepreneurial success.
