Computer Glitch Causes Havoc and Losses on Nasdaq

goombah99 writes "In an illustration of how fragile the electronic stock market system is the NY Times is reporting how a tiny computer glitch rippled through the Stock Markets with buyers who bought low and sold high taking huge losses. An erroneous large sell order was entered. Many people bought at this low price, then signed options contracts to sell these at higher prices, locking in a profit. Or so they thought utill the erroneous low sell order was removed. Now to honor their options they had to buy the stock at a higher price. Since exchanges trust each other's trade prices it rippled throughout the system. There does not seem to be any way to gracefully undo such errors."

    and while the SEC and others do their best to proteect traders, mistakes do happen. This is part of the random process of the markets, and must be accounted for when making a trade, even on options markets.

    If you lost money, sorry. Unless the SEC/others can prove that somebody is liable for the initial mistaken order, you lose. Tough. Trading is risky, and sometimes the risks are completely unforseen.

      That's pure nonsense.

      The markets are meant for people to invest their money in businesses they feel will make a decent return for them. Investment risk consists of inherent risk of the industry, currency risk, political risk, etc. Nowhere in that equation is there EVER risk of a glitch in the computing system factored in.

      Mistakes happen because people are unethical, criminal, or just dumb managers. But mistakes should never ever happen because the system that you gave an order to buy or sell for you decided to have a glitch.

      Someone IS liable. NASDAQ is liable! NASDAQ is a company and it will be sued for the losses that it caused other people. It's as simple as that.

      The investor chooses the risk and the reaction to short term changes. The low risk, long term investor would not likely be affected by this mistake. Such investors seldom keep track of minute to minute prices. Such an investor might notice something funny happened the previous day, and check on the details, but when nothing was found go on with life.

      It the high risk trader that is going to be burned by this scenario. This trader has chosen the high risk levels, and should know the consequences. And, your fantasy world notwithstanding, information is sometimes wrong. (In fact this case is not about computers but information dispersal) Sometimes you lose money. Sometimes you can sue for damages. But these traders are big boys and girl. The smart ones double check information if it seems out of the ordinary (and wrong quotes come by more than you might believe, often direcly from the exchange). They do not run home to mommy and daddy complaining that a 5th grader sold his pubes for $10, and you now want your money back.

      You're at least half right. But this isn't a question of information about prices - if it were, NASDAQ and the ECN would be off the hook. This is a question of whether the ECN executed orders that should not have been executed and NASDAQ didn't cancel them all. That's when risk minimizers are hit.

      If I market buy because the ticker says a $50 stock is selling at $40, it goes through between 10:46 and 10:58, then NASDAQ is right to cancel at 12:30: no problem. If my option straddle executes on the volatility on both sides, one before and one after 10:58, but NASDAQ cancels the options in-the-money (on Instinet) but not the options out-the-money (on another ECN), then its a problem. If I'm an idiot, and leave those options open unchecked through a halt, then its my fault for engaging in a risky behavior and getting slammed in the ensuing short-squeeze.

      Other stocks in the sector were off by 10%, so it was not stupidity to think that a 20% move was legitimate. NASDAQ halted Instinet, but not other ECNs. Archipeligo already announced intentions to file suit with the SEC on the matter. And that won't be the last suit filed on it.

  2. Bound to happen. by dolo666 · · Score: 4, Insightful

    This reminds me of a nugget.

    The stock market is frail, and a fool's playpen. I remember hearing a story about a huge media barron, before the stock market crash that led to the great depression. The mogul was standing in this elevator and overheard busboys talking about how they were going to start playing the stocks. The millionaire immediately sold everything when he got to the office. His reasoning was that if two people who had no money were playing stocks, that they were a sign that the whole system was at fault and doomed. I forget who this person was, so if anyone remembers... hehe feel free to say.

    The guy's logic is correct even to this day, imho. The big companies that go public hope that an infusion of cash will make them more profitable, but it usually ends up that they get to take a break on stockholder's money for a while until it's deadline time again and they have to scramble to make product/service X work.

    The whole system is wrong.

      The fact is that there is no harder work than taking a risk. Things like the stock market allow people to take measured risks in return for a greater reward. It also provides cheap capital for businesses and liquidity in trading businesses. Without it the economy would be less efficient and your "hard work" would buy you a whole lot less.

      Yup. The question is what happens afterwards - do they get corrected and people move on, or do not get corrected and people lose confidence?

      The former seems to have happened here showing that the system has a degree of failure tolerance.

  3. Hyper-transactional databases? by mcrbids · · Score: 5, Insightful

    My first thought when reading the summary above was that this would be an easy problem if managed by a central, relational database system.

    Simply "roll back" the transaction that failed, and the dependencies would cancel themselves out. But, then I realized that the current RDBMS model only allows for a single transaction - you can't nest them.

    Also, transactions are private only - you cannot transact with data in the middle of another transaction.

    Thus, you might have ACID compliance, but only with one level of "undo".

    How hard would it be to create an RDBMS that supports infinite levels of "undo" or transaction/rollback.

    Such that you commit transaction A, which affects rows 1,2,3, and 11. Then, another transaction B which affects (further) rows 2, 3, and 12.

    Then, if you roll back transaction A, transaction B would be similarly affected. I dunno - the depencies may get rediculous - but it seems that this could and should be done at some point.

    Bright idea? Or another noise from an unpleasant orifice?

    Let me know what you think!

    I think the people left holding the bag here are exactly the right ones: The ones who thought they were gonna make instant big profits.

    Not only did think they had bought something something at far below its value, they then signed options contracts to sell what they had just bought at slightly below its regular price. They should have known something was fishy... why would anybody want to pay close to the normal price to them if the price had just plumeted? Why would anybody want to sell to them at far below the usual price?

    The should have known that the rules of the game allowed for their trade to be undone, yet they committed to an options contract that couldn't be undone because if they had hesitated, they risked their "instant profits" going away... their fault.

    From the article:

    Such losses would have been prevented if the markets had not resumed trading until a decision was made on which trades, if any, should be canceled. But with markets intensely competitive, trading resumed before officials had made their decisions. The losers were traders who were not responsible for the errors or the slow decision making.

    However, Archipelago was the first to make the decision to resume trading, so most of the people who got burned did so there. NASDAQ then was caught in a no-mans-land of decision making... their investigation hadn't yet returned an explanation, but Archipelago's actions indicated that they had already made a decision that the trades were going to stick. For a trading halt to be effective, there has to be a trading halt everywhere. The markets should have seperate regulatory divisions, but they all should be coming to the same decisons at about the same time. Archipelago clearly didn't do a good investigation here... that's the question that needs further investigation.
