Oh, so now after several articles, including a video Ticker, we start to see some mainstream media exposure?
“We live in a day when things are measured in milliseconds,” said Sang Lee of the Aite Group, a financial services consulting company. “It is meant to be a level playing field, but if you have better technology you will have the edge.”
Oh gee, nothing like talking out both sides of one's mouth, eh?
Then of course there's this....
Traders at BMO Capital Markets in Toronto said they had also identified a “data deluge” a few minutes before the crash. They said people in the markets were poring over Nanex’s colorful charts.
A few minutes before? Hmmmm...
He and others are tempted to go further, hypothesizing that the bizarre patterns might have been the result of a Wall Street version of cyberwarfare. They say high-speed traders could have been trying to outwit one another’s computers with blizzards of buy and sell orders that were never meant to be filled. These superfast traders might even have been trying to clog exchanges to outflank other investors.
Could have?
Look, let's cut the crap. The markets are supposed to be fair, open to all, and available on equal terms. You are supposed to get your quotes at the same time I get my quotes. We are all supposed to see the same prices, disseminated to all of us at the same time, and we are all supposed to have the same ability to respond.
The premise of a fair market - indeed, the entire word market - is that it is a mechanism to further price discovery. That is, it is supposed to answer the question "What is a fair price for a share of Frobozz corporation?"
But to answer that question one must have fair markets. That is, when I enter an order to buy 100 shares of Frobozz, I must actually intend to buy 100 shares. I must enter a bid with a fundamental purpose and intent of execution of that order.
Likewise, when I enter an order to sell 100 shares of Frobozz, I must actually intend to sell 100 shares, whether they're shares I actually own or ones I have borrowed and want to sell short. I must enter that sell with a fundamental purpose and intent of execution of that order.
Inherent in that intent is market risk. That is, any time I enter an order with an actual intent of execution I am taking the risk that the market price - the "true price" if you will - will go the opposite direction of my entered order. That is, I will lose money.
If any part of my intent in entering that order is to earn a risk free return - that is, if I have knowledge or take an act that makes my entry of that order free of market risk, then in the general sense I have probably violated the law.
"Front running" is one of the manifestations of this sort of unlawful activity. When one "front runs" one has actual and specific knowledge that an order at a higher (or lower) price is about to be made known to the marketplace. The unlawful act is inserting oneself in front of that other order so as to earn a risk-free "profit" - not through price-discovery (the lawful way in which one profits at someone else's expense in the market) but through what amounts to theft.
The reason this activity is theft is that the person who you get in front of is entitled, as a matter of law, to the better price that you steal from them.
That is, if you know that I am about to enter an order to buy Frobozz with a limit price of $100 a share, and the current market price is $99/share - that is, there are people willing to sell shares at $99, I am entitled to the dollar of price improvement. When you insert yourself in front of my order so as to buy the shares at $99, whether you then immediately sell them to me at $100 or not you are stealing from me, in that you are "cutting in front of the line." The persons whom you cut in front of are deprived of their lawful and proper place in the order queue.
Front-running is as old as the markets. In the days of telephones and teletypes on the floor of the stock exchanges, where actual buying and selling took place by open outcry of people, it was common for brokers to learn of a large order and to insert their own order in front of the customer's, so as to be "right there" when the big order moved the price up or down. This has been illegal since at least the Securities Act of 1934, which has extremely broad anti-fraud language in the form of Section 10b(5).
Technology doesn't change the inherent nature of an act.
If your particular "high frequency strategy" obtains it's advantage by being first, then you are inherently attempting to front-run. Whether such activity finds some loophole (or more likely simple willful blindness on the part of regulators) doesn't change the intent of the law, nor does it change the intent of your act.
Indeed, the very fact that exchanges and other trading venues sell "premium" quote services which have as their primary attraction that they are more-current - that is, faster - than the "standard" means by which quotes are disseminated - should be sufficient evidence standing on its own that there is intent to profit not through the taking of market risk but rather by inserting one's activity in front of others before they become aware of the market's movement in price.
Whether this technically meets the "fine definition" of a violation of the laws against front-running isn't the issue.
The issue is that it damn well should, as it is quite clear that the intent is to insert one's activity in front of that which you know is going to occur - and thus by intent such activity clearly meets the common-sense definition.
To the extent such loopholes exist they must be closed, and to the extent that such actions violate existing laws they must be prosecuted.
