Confirming the Flash Crash Omen

  • Print

The highly discussed and quickly forgotten Flash Crash was an omen of what lies ahead for the financial markets. It was a uniquely distinctive occurrence relative to anything we have ever experienced. Likewise, what we are about to witness will be startling and never before observed by this generation of investors. After only thirty days the Flash Crash signal has become unambiguous and historians will wonder why the public didn’t react sooner to its clarion call.

Prior to the May 6th Flash Crash I laid out in an article “Extend & Pretend: Shifting Risk to the Innocent” what to expect. The ink was barely wet before its predictions began to rapidly unfold. The basis for the predictions was the similarities between the rally we have experienced since March 2009 and the rally prior to the 1987 crash. It was striking in comparison to the amount of rise, the rate and the pattern, but more importantly the reason for both rallies. The 1987 crash was attributed to Portfolio Insurance. In 2010 it is about what is referred to as the ‘son-of-portfolio insurance’ or Dynamic Hedging.

Over the last ten years we have systematically accelerated the shifting of risk through the advancement of three new strategies; Dynamic Hedging, Capital Arbitrage and Regulatory Arbitrage. Individually they may seem sound but when pyramided as we have done over this period of time, they set the stage for systemic instability. The underlying bedrock of this pyramid is Dynamic Hedging.

For the full unabridged article: see TIPPING POINTS

The three new strategies:

Dynamic Hedging

Reduces Risk further through recent advancements in High Frequency Trading and Dark Pools

Capital Arbitrage

Hides Risk by removing it from financial balance sheets

Regulatory Arbitrage

Moves Risk to Sovereign entities.


I will not explore in this article how these strategies are being used and how they are building upon themselves (see “Extend & Pretend: Shifting Risk to the Innocent”) but rather I want to focus on what the Flash Crash is signaling and how it relates to the 3 critical flaws of all modern trading algorithms.


Liquidity Driver

Dynamic Hedging and Portfolio Insurance are both based on trend following mechanics. Consequentially both have a strong bias towards momentum correlation and the ability to adjust to changes in momentum.

One of three flaws in most mathematical algorithms is the assumption of market liquidity. When markets breakdown, liquidity quickly evaporates and this often makes execution impossible. The more serious the breakdown the more serious the liquidity problem will become. Also, the liquidity issue is often simultaneously seen across multiple markets where modern dynamic hedging operates.

The Flash Crash confirmed that Dynamic Hedging has now been modified by major players to take this into account and this is why the algorithms ‘grabbed’ as much liquidity as fast as it could, at accelerating rates - while liquidity was still available. The employment of High Frequency Trading has now emerged as a strategic imperative within state-of-the-art Dynamic Hedging Systems.

Counter Party Risk Driver

A second flaw of trading algorithms and markets is counter party risk or the sudden failure of a counterparty to deliver a contracted obligation. With banks & financial institutions still having serious amounts of off balance sheet risk tied to Structured Investment Vehicles (SIVs) and corporations to Special Purpose Entities (SPEs) the ability to rapidly shift hedging on any early indications is now paramount.

Shifts in LIBOR, TED Spread, and OIS-Swap spread must now be acted upon in milliseconds. The Flash Crash occurred when all these input drivers were moving as a result of the Euro crisis.

Sovereign Debt

Changes in Sovereign Debt Ratings have a profound impact on Collateral Calls associated with the $430 Trillion Interest Rate Swap market. Collateral Calls are typically tied to Credit Ratings, LIBOR, Spreads and Asset Values. Hedge positions on Trillion Dollar portfolios must now be repositioned in minutes versus days or even hours while high volume liquidity and price is available.


A third flaw of trading algorithms is their assumption of ‘continuity’ or continuously operating markets. Instability of any system can lead to compounding results or exponential change until the function reaches a point of discontinuity. The Flash Crash was the most severe of a number of market moves lately that evidenced higher amplitudes, shorter frequencies and steeper rates of change which are signs of instability in the market.

As much as the market became fixated on the Flash Crash, what has received little attention are the dramatic “Flash Dashes” where markets on close for example are seeing 20 handles on the S&P. For long term traders these are worrying tell tales. To others they are evidence of accelerating and compounding Dynamic Hedging issue.


It is readily apparent that present day markets have built across-market dynamic hedging machinery with a hair trigger. This trigger is designed to launch unimaginable trading volumes in less than 250 microseconds, across global exchanges, operating under different & still uncoordinated rules. The activation could be any number of events but my sense is it will stem from the dramatic contraction in money supply. Despite massive central bank actions, money supply as measured by MZM, M1, M2 is still de-accelerating and in the case of the difficult to obtain M3, is contracting. All of which is presently going unheralded by the mainline media

When a highly leveraged system is built on the basis of liquidity and liquidity is shrinking, it is only a matter of time.


Flash Crashes and Dashes will become more apparent. By their very nature they are de-stabilizing. When certain natural frequency boundary conditions are broken the markets will eventual seize up despite all circuit breakers and attempts by authorities to stabilize markets. These boundary conditions are not presently understood nor seen to exist. For practitioners of Chaos Theory they are a basic tenet to understanding any phase shift.

We are nearing a ‘phase shift’ in what I will refer to as the energy level of the markets. Elliott Wave practitioners would refer to it as a ‘higher degree pivot’. W D Gann practitioners would call it a Gann Cardinal. Economists call it a “Tipping Point”. I call it a ‘Critical Point’ or ‘Chaotic Transient’.

A trader would just call it a market melt-down or melt-up! Few alive have ever witnessed either.
