Anywhere one turns these days, bashing HFT is the new market normal. Having written 150 articles on the topic, beginning in April 2009, we are happy to have brought the world’s attention to this most dangerous of market aberrations. Yet until the SEC finally bans the practices of micro churning, quote stuffing, positive feedback loop chasing, flash trading, subpennying, DMA accessing, and all other aspects conceived merely to provide some market participants with an unfair advantage over everyone else, the fight against HFT must continue.
Which is why we draw your attention to two items: the first is a paper by Bluemont Capital "The Marginalizing of the Individual Investor" in which the authors question if HFT has distorted true market valuation (yes) and to what degree. Some relevant soundbites: "Unfortunately, high-frequency trader interaction with computerized algorithms of large-cap financial institutions is providing opportunities for high-speed, virtually undetectable market manipulation", "At a minimum, computerized high-frequency and algorithmic trading are undermining traditional value investing strategies. Short-term liquidity and data movements are distorting information on real business performance", "Essentially, high-frequency trading platforms function as positive feedback loops. Engineers treat positive feedback loops as inherently unstable, as each positive response generates stepped-up repetition of the same actions. Positive feedback loops result in an ever- expanding balloon, but like all balloons, the risk of bursting increases with the balloon’s size." It concludes that the "continuing advances in computerized trading pose challenges for regulators throughout the world—and leave individual investors marginalized… Regulators should not only seek to assure that markets are able to continue to function under stress, but they also need to devise remedial actions that protect individual investors who have fundamentally different objectives from the high-turnover objectives of high frequency traders and computerized algorithms."
The other notable item is the appearance of our friends at Nanex on ABC radio over in Australia, where firm founder Eric Hunsader discusses the previously highlighted concepts of latency arbitrage as a potential progenitor to the May 6 crash, as well as possible ways that the NBBO arbitrage could have provided for unfair and illegal mispricing opportunities for a select few.

The Day The Market Almost Died (Courtesy Of High Frequency Trading)

A year ago, before anyone aside from a hundred or so people had ever heard the words High Frequency Trading, Flash orders, Predatory algorithms, Sigma X, Sonar, Market topology, Liquidity providers, Supplementary Liquidity Providers, and many variations on these, Zero Hedge embarked upon a path to warn and hopefully prevent a full-blown market meltdown. On April 10, 2009, in a piece titled "The Incredibly Shrinking Market Liquidity, Or The Black Swan Of Black Swans" we cautioned "what happens in a world where the very core of the capital markets system is gradually deleveraging to a point where maintaining a liquid and orderly market becomes impossible: large swings on low volume, massive bid-offer spreads, huge trading costs, inability to clear and numerous failed trades. When the quant deleveraging finally catches up with the market, the consequences will likely be unprecedented, with dramatic dislocations leading the market both higher and lower on record volatility."
Today, after over a year of seemingly ceaseless heckling and jeering by numerous self-proclaimed experts and industry lobbyists, we are vindicated. We enjoy being heckled – we got a lot of it when we started discussing Goldman Sachs in early 2009. Look where that ended. Today, we have reached an apex in our quest to prevent the HFT "Black Monday" juggernaut, as absent the last minute intervention of still unknown powers, the market, for all intents and purposes, broke. Liquidity disappeared. What happened today was no fat finger, it was no panic selling by one major account: it was simply the impact of everyone in the HFT community going from port to starboard on the boat, at precisely the same time. And in doing so, these very actors, who in over a year have been complaining they are unfairly targeted because all they do is "provide liquidity", did anything but what they claim is their sworn duty. In fact, as Dennis Dick shows (see below) they were aggressive takers of liquidity at the peak of the meltdown, exacerbating the Dow drop as it slid 1000 points intraday.
It is time for the SEC to do its job and not only ban flash trading as it said it would almost a year ago, but get rid of all the predatory aspects of high frequency trading, which are…
