Stock Market Manipulation By Millisecond Trading

cfa22 writes "Nice piece in the NY Times today on ultra-fast trading on the NYSE and other markets. The 'algos' that make autonomous trading decisions have to be fast, but I wonder: Is network speed ever a bottleneck? Can anyone with inside experience with millisecond trading provide some details for the curious among us regarding hardware architectures and networking used for such trading systems?" According to the article, high-frequency traders generated about $21 billion in profits last year.

  1. 1588v2 aka Precision Time Protocol Version 2 by statusbar · · Score: 4, Insightful

    I believe that precision millisecond stock trading globally is the real reason behind the IEEE 1588v2 precision time protocol. The cisco 9000 enterprise switch supports it. Support has been lacking in smaller switches. The only other group using PTPv2 is the cell phone industry.

    The interesting part of PTPv2 for me is that it is used in the 802.1AS protocol ( http://www.ieee802.org/1/pages/802.1as.html ) which is one of the foundations of Audio Video Bridging (AVB) http://www.ieee802.org/1/pages/avbridges.html - Which allows for real time low latency low jitter media streams transported via ethernet with guaranteed bandwidth.

    Just yesterday I was joking with friends: Forget about stealing the rounded pennies from bank accounts, criminals could re-program the PTPv2 implementation in switches to steal milliseconds of time during trading!

    Anyways, back on the original question, no, network speed is not so crucial once all of your packets are properly timestamped.

      On the one hand, you can call this 'perfect price discovery'
      OTOH, that specific set of behaviors fundamentally breaks the traditional way that the imperfect markets have worked.
      And just as importantly, it represents an unfair trading advantage that you or I will never have.
      Allowing this behavior doesn't further market activities, it just allows a few players to accumulate wealth at everyone's expense.
      Seems to me that the solution is to close the loophole that allows this to happen.

      As an investor (which is the term the article is using--among whom are you and I), you had better not be trading like these traders. These traders are Market Makers, which are specialized traders that provide liquidity (a very important thing) to the market. If you don't have real market makers, then the stock market is going to look like what Mortgage Backed Securities look like right now: there will be periods of time when nobody wants to touch the stuff, and if you are an investor, you are truly screwed if you need to buy or sell your security.

      These market markets are looking to capture a spread (the cost to buy or sell)-which by the way is much better for the investor than 5, 10 or 20 years ago--capturing a fraction of a penny a billion times a day. The key component to a market maker's success or failure is understanding supply and demand. This was true even before the computers came in. The computers can only detect it much faster, so you get what you mentioned first--better price discovery. It's not that the investor is getting screwed out of 20 cents, it's that they're not getting the 20 cent discount they used to when the market makers were humans standing in the pits.

      As an investor, you really shouldn't care if you get Broadcom at $26.20 or $26.40. Yeah, it's nice if you get it for the cheaper price, but the reason you're buying Broadcom is because you think it's a good investment, and if $0.20 ruins that investment for you, then I guarantee it's not a good investment.

      The $0.20 might ruin a day-trader's day, but day-traders are not investors nor market makers. You and I are not day traders. The only thing the electronic market makers ("high-frequency traders") ruin are slower, human-based market makers' profits and day-trader's profits. It's certainly not worth an article in the New York Times.

    The problem is the start-up cost. Buying the necessary hardware, obtaining the required data sources, developing the necessary analytical formulas and coding them efficiently costs a *lot* of money. So it's the free market of people who already have a lot of money and time, or simply an enormous amount of money.

    I'm not entirely against it in some cases; well implemented it can smooth out market fluctuations and value securities more accurately. But it still makes me squeamish: It's yet another mechanism by which the rich get richer, and the poor get left behind. Every trade a "normal" person makes will end up costing a small amount more, and the difference goes into the pocket of the HF funds. It feels very much like the "shave the fractional cents off interest calculations" scam: No one suffers individually suffer, but it still feels wrong.

      You're wrong.

      High frequency trading means that more trades happen in general. This extra competition to fill orders drives down the difference between the buy and sell prices and greatly reduces arbitrage situations (ie, the difference in price between the same stock listed on different exchanges and possibly in different currencies).

      So, if you buy or sell a something, you're giving less money to the market-makers and you're getting a more "correct" price. It levels the playing field.

      And it's true that arbitrage and hifi trading are a zero-sum game. That's why it's an arms-race at this point.

      You're wrong.

      High frequency trading is based on exploiting knowledge that isn't available to everyone. Its akin to insider trading and should be regulated.

      Lets say that a company announces something that means big profits. Lots of people then place orders to buy. Due to a special agreement with NASDAQ or whoever, a high frequency trading program will see these orders getting ready to be placed and make their orders a fraction of a second before everybody else. So they get the stock for slightly cheaper and then sell it off quickly for a profit. They end up making money off the people that don't have access to high frequency trading. They don't make a lot off of each trade, but they make up for it in volume.

      If this is allowed to continue, the markets will lose their credibility. Hopefully they will either self regulate or government intervention will take care of the problem.

    In this case, that is not quite what 'liquidity' means. When you discuss 'the liquidity of assets' you're generally referring to how easily and cost effectively those assets can be converted into cash or other, spendable assets. However, liquidity of a stock/bond/credit in this context is referring to how much that market is actively being traded. A liquid market is constantly moving, an non liquid market is stagnant. Theoretically, the more liquid a market is, the closer it's price is to its actual market value. This is related to the other kind of liquidity, as if you have an investment in a stagnant market, it would be very difficult to sell and turn into cash, but in a financial market context, that's not really what they're referring to.

    This is not what happens. Such corporations don't simply "disappear", their assets and personnel persist, and are snapped up at a steep discount by other, similar corporations which haven't collapsed yet. These asset strippers leave the debts: the creditors and the creditor's shareholders have to write them off, creating losses that can wipe them out too.

    On the way down, the desperate management strips as much out as they can, in self-awarded bonuses and by running as much of the inbound cashflow through - extracting more money from other corporations so that they are damaged - and constraining outbound. The end result is more collapse and economic suffering, not less.

    The alternative to this law-of-the-jungle, Libertarian no-tax, no-fed-money "ideal" is progressive taxation. It's an existing mechanism for inhibiting John Galt from excessive, unwarranted greed, and it can be used to redistribute wealth in a directed fashion.

    No, it doesn't.

    I think our entire society (Except stock traders) would be a hell of a lot better off if you were required to own stock for six months.

    People might actually start purchasing stock based on actual company performance. They'd start expecting to make money via dividends, aka, company profit, instead of random fluctuations in the price caused by CEO manipulation.

    Like the CEO, oh, firing half the workforce to cause an upward stock price bump for two months, so they get their bonuses. Oh, and incidentally cripple the company, but what the fuck do they care, they're out the door to another company.

    Stock ownership is company ownership. It is not a fucking bingo game. Although if that existed by itself, that would be fine...the problem is that the idiotic bingo games get play by the board, which starts operating the company for the benefit of the bingo game, instead, of, I dunno, the actual company.

    As a lefty, I'll complain when companies put profits ahead of employees, but hell, they've stopped doing even that. At least that system worked somewhat. Make the workers too unhappy, abuse them too much, and you don't make as much money.

    Now the people running the company are rewarded solely based on an idiotic bingo game, which bears no relationship to how much money the company makes. And it doesn't matter how much the workers abused, because the actual business of actually producing goods and services is irrelevant to the paycheck of the people at the top.

    Until the entire company collapses, at which point they walk out the door with a shitload of money and head to another company, whose board will happily hire them because it will make their stock go up. Which they can sell to poor unsuspecting suckers, and walk away with a lot of money to pour into the next business, building it up as an actual industry, until they can hire a stock-pricing oriented CEO and suck all the cash out of that stock, too.
