Knight Trading Losses Attributed To Old, Dormant Software

New submitter alexander_686 points out a Bloomberg article about the cause of Knight Capital Group's $440 million algorithmic trading disaster from a couple weeks ago. The report says a dormant software system was accidentally activated on August 1, which immediately began increasing stock trade volumes by a factor of 1,000. The Wall Street Journal has further details: "Knight Capital Group Inc.'s accidental trades earlier this month were triggered by a flawed upgrade of trading software that caused an older trading system connected to the computer code to inadvertently go 'live' on the market, according to people familiar with the matter. The errors at Knight on Aug. 1 involved new code the Jersey City, N.J.-based brokerage designed to take advantage of the launch of a New York Stock Exchange trading program, which was introduced that day to attract more retail-trading business to the Big Board, the people say. ... When NYSE Euronext trading floor officials called Knight at about 9:35 a.m. to try to pinpoint the cause of unusual swings in dozens of stocks, just after the Big Board opened for trading, Knight traders and their supervisors had a difficult time detecting where in its systems the problem was located, say people familiar with the morning's events. The NYSE had to call Knight several times before deciding to shut the firm off, the people say."

      You really don't know what you are talking about. Sure the market can get volitile but most companies in the S&P 500 actually do have value. If you don't panic and cash out during the crash you will be fine. All of the financials in the S&P 500 are about 15%.

      If you are investing long term and are diversified these panics are a good time to buy.

      The problem with that idea is that sometimes these high frequency traders also cause volatility spikes in the market, triggering other computer programs, and, sometimes, humans, to react as though the spurious trades were intentional.

      While I also loathe HFT as a scourge on the market, I think the NYSE's overall response is a good one: when abnormal trades occur as a secondary effect of other's mistakes, abort them.

      Note that the ca. $440 million loss Knight took was BECAUSE they couldn't unwind the bad positions they bought into. Goldman Sachs bought the entire block from them at a discount. Knight didn't get any kind of parachute.

      Where do you suggest one goes for short-term, no-risk investments? I want to go to there.

      Money-market funds. They invest in short-term Treasuries and top-rated debt. They try to be diversified, so even an unlikely nasty surprise won't nick you much. You won't get much of a return, but your money will be most likely safe (there's no absolute guarantees anywhere, but if the money market funds go south, there's not likely to be any safe place elsewhere). With current low interest rates, you'll probably make a return of less than 1%, though.

      I use a method by the late great Harry Browne he called failsafe investing.

      Here is the summary. Divide your investment into quarters.
      25% S&P 500 stocks
      25% 30 year Treasury Bonds
      25% 100% Treasury Money Market (If you can find one. They pretty much all went under after they put FDIC on money markets)
      25% Gold Bullion Coins

      As you save add your funds to the Cash (Money Market) portion.
      Every once in a while check the balances. If any gets above 35% or below 15% of your total portfolio re-balance it to 25%.

      The beauty of it is that when anything bad happens it is usually people running from one of these to another. This allows you to automatically buy low and sell high.

      I've averaged about 12% per year for the last 10 years. You don't get as good of a return long term as the S&P 500 but it's also less scary.

      No kidding. Although it wasn't reversed in Knight's case, there have been many flash crashes that have been reversed, making it so that profit is almost guaranteed for HF traders: good bets go through and bad bets get reversed.

      I was personally affected a couple of years ago. I had an outstanding bid (limit order) on a stock at what I thought the stock was worth, although significantly lower than the going price, so I could pick it up in case there was a temporary drop due to negative news or whatever. The "whatever" happened; my open order got filled by HF traders due to a flash crash they caused in that stock. I got a call from my broker later in the day to tell me the SEC reversed the trades during that flash crash, including mine. So a few thousand dollars that by all rights should have been mine went back to the HF traders.

    that say this stuff spells the end to high freq trading. The trouble is HFT is less about investment and more about skimming off the top. HFT Traders take a percentage of a company w/o ever actually owning it. The increase in liquidity is so small that legitimate investors don't even notice it (who cares if my stock sells in .1 milliseconds vs 5 minutes if it was an investment). No real money was lost for the HFT'ers because they were never actually creating anything productive in the first place. They'll recover from this and continue to be yet another bloated tick on the face of capitalism.

      Liquidity isn't about time, it's about spread. Stock markets are double-auction systems, where you are free to bid and offer at any price you want. Trades only occur when someone offers a stock for less than someone else's bid price. The stock has a 'price,' and to buy stock you have to bid a little higher, and to sell you have to bid a little lower. The difference between the bid and offer price is the spread, and the spread represents an inherent transaction cost to most investors.

      Now liquidity is just how easy it is to convert your stock into cash. There is always some liquidity, as long as you're willing to accept a bad deal. You offer to sell your stock cheaply enough, or buy high enough, and somebody will buy or sell. Of course, on blue chip stocks, the spread has always been pretty small, so it has never cost a lot to trade in those stocks. But in medium-cap and small-cap stocks, where HFTs have had the biggest impact, they've reduced spreads enormously.

      Twenty years ago before the rise of HFT traders, you might had paid a market maker $0.50 / stock on the spread for a trade in a medium-cap stock. If you want to rebalance your investment portfolio annually, those kinds of transaction costs could wipe out your gains. It effectively priced individual investors out of the market, and if you wanted to save money you were forced into the hands of large institutional investors, who will happily charge you a 2% management fee for the pleasure of handling your money.

      Today we take it for granted that most stocks have very small spreads, and you can make regular trades without seeing all your gains lost to transaction costs. HFTs have put the Serious Men in Suits market makers out of business, and have pushed the cost of trading down to the point where the individual can manage their own savings, without having to fork over most of their profit to other Serious Men in Suits.

      So yeah, you may not like high frequency traders, but they're better than the old-boy networks of "specialists" and stockjobbers that they replaced.

      Twenty years ago it was also much harder to match up buyers and sellers, and actual trades took a lot longer. It's hard to say how much of the decrease in spread is due to high frequency traders and how much is due to improved technology providing a more efficient, easier to access market.

      Not that there seems to be anything particularly bad about encouraging people to buy long term investments.

The investment will give the firms a 73 percent stake in Knight once the shares are converted into common stock.
