      Market liquidity is extremely important. If you decide you want to trade your shares you want to be able to do so quickly and with a low trading fee. And you want to be able to get the same price no matter where you sell them, London, New York, Hong Kong.

      A high trading volume facilitates this. A limit on how fast a broker can trade could cause people to be unable to sell their stocks if they want/need to.

      Many experienced investors believe that the three most important things about an investment are liquidity, safety of principal and yield. In that order.

      I remember when my father was investing in the stock market - an order to his broker would cost $150 to execute and take hours to process. And the price was fairly unpredictable. Now you can do an order at 1/20th the price, be pretty sure of what the execution will be because of the ability to place limit orders and get confirmation nearly instantly.

For a while, people tried to keep up - certainly not without a little greed of their own. Refinancing their house to fund their lifestyle. Living on their multiple credit cards. Taking out 50 year ARM mortgages and other shaky deals. So Americans were actually starting the fall into low income well before the 2008 bust. As their wealth dissapeared, they started settling into the new lifestyle.

    I view high-frequency trading (HFT) as great for society. Here is why: What HFT gives you is the fairest and most accurate (best) price for something. When there are many, many trades, the price gap between the individual trades becomes so low that there is no chance that you'll pay too little or too much for something or that you'll wait too long for your trade to happen. I'm talking about people who just want to buy something, not HFT traders.

    You're hungry and you want to cook yourself dinner. Your dinner is made up of commodities that are traded, except perhaps for the parts that you bought at the local farmers market. But you and the farmer used gas and a vehicle of some sort to make the transaction. If you rode your bike, your bike is lubed with oil and made of steel, etc. With HFT in play, everything that went into the transaction was bought and sold at the fairest price possible. Nobody got gyped because of low market volumes that day, and nobody had to pay a gigantic fee to a broker because the cost per transaction is now tiny.

    Of course you have issues like the flash crash. The best way to look at the flash crash is like this. Shares of John Gotts (JG) are worth $40, based upon fundamentals (intrinsic worth) and an idea about the future. Somebody sold a gigantic number of shares of JG for $20. Excellent computer algorithms put in buy orders for JG at $15 and possibly foolish computer algorithms found a way to sell shares of JG at that price, foolish if they bought the shares for more than $15 or smart if they bought the shares for less. The spiral kept going downwards due to both foolishness and intelligence. You can see that there were many, many winners. Every algorithm that bought shares for JG at less than $40 had the potential for a huge windfall. There are no rules against creating an intelligent HFT to look for mini-flash crashes and make a killing as a result. Fortunately or unfortunately, many of the trades that did happen were unwound by the exchange.

If you are a lender and you loan $1million, with a 10% risk of default then you have a 1 in 10% chance of losing everything and on average you get 90% back. If you make 10 loans of $100k at 10% risk then you've got a more complex risk but what you can avoid is the black-or-white nature of the single loan where you either get what you expected or get nothing. So by collateralizing a bunch of loans you are creating a risk curve. The odds of you losing everything are much lower, and the presuming your loan pays back some amount more than you lent your risk of making any loss is significantly reduced. It's the same as insurance. You expect occasional large payouts but overall you take in more than you pay out.

    So having a product made of non-triple-A loans is fine, so long as the risks are correctly understood - a problem with a vast number of things in finance. Two things occur: First people don't take into account, or aren't aware of, the interconnected nature of the risks - they are not independent. In the real world someone might stop paying their mortgage due to events that are connected to them only, but as a group the loans may be affected by much larger scale events (e.g. economic downturn, war, environmental disaster). Second is that the responsibility for the risk was passed on: the person making the loan gets their money when they sell the CDO to the market so their need to ensure that they have correctly analyzed the risk is significantly reduced, hence all the selling of loans to people who were in no way able to repay them. The people buying the CDOs _should_ have been thoroughly investigating the products they were buying - at least some kind of independent audit sampling the quality of loans to ensure that the risk matched what was being presented - but while everyone was making money that doesn't happen, what could be wrong when everyone's getting richer?

    The whole thing is not really any different to how most stock market investments are made. Diversify risk so that isolated drops in value can be absorbed and the overall investment turns a profit. If there is a major stock market shift then everyone loses - pension funds etc., the big, long-term investors that everyone wants to see lose a lot in these situations. Playing a long term game means they recover in time, but still they are affected by systemic problems and in some cases affected by poorly categorized or unknown risks (financial/accounting scandals spring to mind).

    In fact the only thing to do is guarantee some of those products, to stem the panic and cut the losses. On the other end there need to be tighter regulations on lending, right at the end-user point. I don't know about the US but in the UK this is definitely the case - we already have pretty strong regulation around lending and especially mortgages and people I know who are mortgage assessors for lenders are now incredibly cautious and will follow requirements to the letter - partly as every application they approve will be checked and any discrepancies mean that everything they've done will be thoroughly investigated.

    The government involvement is a trade-off between a true free-market where, yes, all the people who made out like thieves in the boom will be shirtless in the bust and having some kind of limits on the damage that can occur. Allowing an enormous crash like we would see without the bailouts will affect everyone. Pensions, investments, businesses, economies will all collapse and that will leave _everyone_ in a bad situation. Perhaps a few bad people will learn a lesson, but we will all definitely take an enormous punishment. It's not fair, but nothing is, and to take that as a basis for action is unfortunately naive. The best of a bunch of bad choices is more careful regulation. I'd like to see a much more proactive and independent approach to quantifying the risks being taken in some of these areas and a bit more backbone fro

    As one of the articles explains, HFT algorithms trade almost exclusively based on other trades. Guess what behavior is almost guaranteed to cause a bubble?

    Human behavior.

    Well, yes, that too. But positive feedback loops are a real bitch. In a real, physical system, positive feedback can be mitigated through damping, time delays, etc. In the worst case, you are still limited by the strength of your actuators - you'll saturate the system, or become slew-rate limited. Sticking a microphone next to a loudspeaker may make an unpleasantly loud sound, but it doesn't immediately become infinitely loud. HFT has the potential to blow up, almost without bound, almost immediately. Would the liquidity and purity of the market really suffer that much if the minimum hold time was, say, one second? At the very least, it would slow the ridiculous arms race of who can clear the most trades per second. I'd be pleased it we could free up the brainpower of some of those very smart people to solve more important, though less immediately profitable, problems. When a billion-dollar investment to shave a millisecond off latency times becomes worthwhile, it is time to change the game to straighten out our priorities.

    Dunbal, I don't think you understand the latency required to do HFT.

    A great deal of their advantage comes from housing their computers as close as possible to the stock trading computers. The gov't allows them to store and connect their equipment so closely, giving the HFT traders an unfair advantage. If the gov't wanted to stop it, they would simply say: "Nope! Go put your servers somewhere else!"

    HFT would become unprofitable for many of the most abusive uses overnight.

    While I will grant that HFT has a role in lowering spreads and increasing liquidity,
    this comment by mfw13 offers a different perspective:

    High-frequency trading harms longer term investors by distorting prices.

    Fundamental to the orderly functioning of markets is the idea that asset prices reflect the underlying value of assets they represent. In the case of stock markets, this means that the price of a stock at any given time should represent the perceived value of the assets it represents. This implies that trades are being made which reflect informed opinions and judgments about whether the current price of an asset accurately represents the present and/or future value of its underlying assets.

    However, algorithms do not have the capability to make these types of judgments. Nor do they care about the present or future relationship between price and actual underlying value. All they care about is pricing inefficiencies.

    This is why high-frequency trading is so dangerousi.e. because it does not care about the relationship between underlying asset value and current price which is the underpinning of orderly and well-functioning markets.

    Why would any sane person invest in the stock market when they have no faith that asset prices are accurately reflecting the value of their underlying assets? High-frequency trading is now such a high percentage of overall trading volume that the long term value of an asset barely factors into its current price at all.

    Ten years ago, a billion shares a day was considered to be huge volume.now its 4-5 billion shares a day, and let me tell you, all that extra volume isn’t coming from rational investors making judgments about the long terms values of stocks.

    HFT is only providing a solution to the supply/demand of the market at any given point in time

    NO. HFT is figuring out that I want to sell at $3 a share, and someone else wants to buy at $5 a share, then buying from me and selling to them before the other party can find my deal. Without HFT, We might have met in the middle, and both seller and buyer make a dollar per share on the deal. HFT, just leaches $2 out of the market for what? "Liquidity"? You've got to be kidding me.

    What caused the economic collapse was the bubble in the housing market that caused people to take out unreasonably large mortgages they had no possibility of repaying.

    Not at all. Every subprime and underwater mortgage in the US could have been paid in full with significantly less than $500billion. Yet, just the first TARP bailout of the banks was what, $900billion? And subsequent banking bailouts come to another trillion, trillion and a half, not to mention "quantitative easing" which has cost us another half to one trillion.

    AIG did not collapse because of people not being able to pay their mortgages. Same with Merrill Lynch. They were taking those mortgages and leveraging them thirty to a hundredfold. And the thing with leverage, in money as in physics, is that a small bit of energy at one end of the lever makes a big movement at the other.

    And the problem gets worse to this day. Derivatives are inherently dangerous, but the risk is socialized so that the next time a big bank messes up, maybe from a little hiccup in their automated trading model, it's you and I that are going to be on the hook for the damages, just like last time.

    And still, there is extreme political opposition to tightening up the regulations on these guys. Any politician who makes any effort to clean up this dangerous mess is targeted for destruction (example: Elizabeth Warren).
