One Theory About Last Monday's ETF Implosion





Attempts to explain exactly what happened last Monday when prices for a whole host of ETFs and mutual funds diverged markedly from fair value abound and while there's no way to know for sure exactly what went wrong, FactSet has drawn some tentative conclusions after conducting a bit of "voodoo, tea-leaf reading."

Head Trader Of World's 4th Largest Hedge Fund Caught In HFT Frontrunning Scandal





Shortly after we reported the latest market-rigging scandal, in which ITG was busted for frontrunning sellside clients in its dark pool in what has been since dubbed a "trading experiment" (because it sounds better than criminal conspiracy to defraud clients), and which will cost the company a record for a private Wall Street firm $22 million settlement, we had one question for AQR's Cliff Asness yesterday morning: "Hi @Cimmerian999, is Hitesh Mittal the AQR employee who was formerly at ITG and is part of the SEC settlement?"   We got no answer from the AQR head, but luckily Bloomberg noticed, and as it turns out the answer to our question was a resounding yes.

Secret Court Permits NSA To Keep Collecting Our Data





Earlier this week the FISA court ruled the NSA can continue the bulk collection of phone metadata until November 29. This comes after Congressional gridlock allowed for Section 215 of the Patriot Act, the legal cover for the collection program, to expire on June 1.

HFT + Inept Regulators + Fed Distortion = More Flash Crashes





"I think we have to blame central bank intervention. How can we not? It’s all around the world. They’re setting interest rates at a ridiculous level. Quantitative easing is distorting all sorts of prices of assets. How do you price things anymore when you have such a giant manipulator out there?"

Why Sarao Is The Flash Crash Patsy: He Threatened To Expose The "Mass Manipulation Of High Frequency Nerds"





The CME contacted Sarao about his trades after concluding he appeared to be significantly swaying opening prices.  Sarao explained some of his conduct to the CME in a March 2010 e-mail as “just showing a friend of mine what occurs on the bid side of the market almost 24 hours a day, by the high-frequency geeks.” And the reason why nobody touched Sarao until just days before the 5 years statute of limitations following the Flash Crash had run out, is the following: "He then questioned whether CME’s actions regarding his activity meant the mass manipulation of high frequency nerds is going to end."

The answer was no.

The Fed’s Trapped In The Corner With An Empty Bucket





In response to questions posed by Santelli, former Dallas Fed president Richard Fisher made two points which were both salient if not downright prophetic. The first: “Well, what worries me is how totally lazy investors have gotten, totally dependent on the Federal Reserve and I find this to be a precarious situation.” The second: “Are we vulnerable in my opinion to a significant equity market correction? I believe we are. Not only has the Fed painted themselves into an even tighter corner – they’ve left no clear path as to now kick the empty can.

US Treasury Warns Investors Underestimate "Potential For A Market Reversal", Take "Low Volatility For Granted"





"Investors may have taken low volatility for granted and underestimated the potential for a reversal. While quantitative easing policies are intended to encourage investors to buy risky assets, there is also a risk that the perceived reversal of such policies will lead investors to turn the other way, triggering market instability.... Similarly, investors may have become too sanguine about the availability of market liquidity — the ability to transact in size without having a significant impact on price — during both good times and bad. Accommodative global monetary policy, coupled with the Federal Reserve’s purchases of large amounts of low-risk assets and changes in risk sentiment, helped to compress volatility and risk premiums.

Asian Gold Traders Suspicious Of Recent "Turbo Steroid Moves"





It will come as no surprise to regular readers that gold (and silver) have suffered from 'odd' violent down-slams in the last few months but, as Bloomberg reports, those 'sneak-attacks' have become increasingly more prevalent during the thin illiquid hours of the Asia trading session. "It is unusual for Asia to be seeing these busy trading sessions," notes on trader, adding that "consensus seems to be that there is a big increase in algorithmic and high-frequency trading in this time zone." The trend began on Oct. 31, with gold futures falling $11 in a minute on nearly 9,000 lots (20x the norm) - all happening when the Chinese market is at lunch. As one Hong Kong precious metals trader remarked, "someone is utilising these thin trading volumes to get a turbo steroid move."

The Broken Market's Latest Creation: An Algo To Offset The Impact Of Other Algos





 Trader's Magazine reports that "as part of KCG's continued push into the institutional trading side of the business"... which is a euphemism for please trade with us: we won't blow up again, we promise... "the well-regarded and historically focused market-maker [ZH: if you keep repeating that it magically comes true, just ask world-renowned trader Dennis Gartman] has built its first brand new algorithmic trading tool - Catch."  What does the algo known as Catch do? Well, supposedly it offsets the impact of all other algos who have crushed market liquidity.

Anti-HFT Revulsion Grows: IEX Ties For Fourth In Dark Pool Trading Thanks To World's Largest Wealth Fund





While Wall Street is certainly free to broken record that Michael Lewis' hugely popular story about HFT and market rigging did not impact the natural course of events, the reality is it did: the collapse in Barclays' dark pool LX (shown in the bolded red line on the chart below), in the aftermath of the NY AG case against the British bank, has been documented in the past, and is just one example. An even more vivid case study comes from the surge in popularity of upstart dark pool IEX (green dotted line below), the protagonist of Lewis' Flash Boys book, and which out of nowhere, has just tied with Lavaflow's dark pool for fourth spot in ATS trading with just over 200 million shares in the week ended October 27. The catalyst? Norway's sovereign wealth fund just said not to HFT parasites.
