The Cringely Interpretation

I've enjoyed reading Robert X. Cringely's articles on technology since the late 1980s when he published in InfoWorld. He's still at it, he's still fascinating, but now it is via his blog. Here is his theory of how technology, "the machines", on Wall Street are killing us...
At any given moment in the market there is more than a $1 trillion in cash that can be brought to bear in seconds by computers that are functioning essentially like piranhas. The cash isn’t held in a few funds or hidden behind some mainframe interface – it is held by hundreds of workstations each operating independently yet as part of a global economic system – conscious or not.

These trading workstations are running in hundreds of offices, all scanning the same data. They have learned over time that certain signals lead to certain outcomes. They may be following an alpha trader but they don’t have to because at some point the market signal, itself, is going to be too strong to ignore.

Here it comes. An alpha trader makes a bold move against a firm or, more likely, against one or more of that firm’s financial products. Say the firm is big stupid AIG, an insurance company, and the instrument is a credit default swap sold by AIG.

Though AIG seems to have forgotten or ignores it, Credit Default Swaps act like insurance and are treated by the market like insurance, but they technically AREN’T insurance. They are ultra-hyper-purified demonic risk and nothing else. That’s because CDS’s are not regulated (they are in fact IMMUNE to regulation – funny that), they can be shorted without having to EVER actually own the underlying security (naked shorts of CDS’s are perfectly legal), because they don’t have to be owned the volume available to be shorted isn’t limited, and – here’s the best one of all – there’s no requirement that the trader have any causal, custodial, or familial relationship with the covered debt. In other words, while most credit default swaps are intended to hedge debt defaults, they don’t have to be. It’s like buying a life insurance policy on the guy down the hall because you hear him coughing at night. His death is meaningless to you so buying the policy is just a gamble, not insurance.

Here’s how it works in practice. The alpha trader senses, guesses, or maybe just wishes for weakness on the part of AIG and its particular CDS issue, so he shorts that mother. The signal from that short (it is big and aggressive, having as much force as possible) is detected by 500 trading workstations running genetic algorithms – workstations that are not regulated in any sense whatsoever. AIG’s CDS begins to glow in front of 500 junior traders. Some programs kick-in automatically and sell, too. The CDS glows even brighter and begins to throb as if its heart was beating. Traders pile-on like piranhas, sensing opportunity, smelling blood, until the CDS is oversold to nothing, until it is dead.

What we’ve accomplished here, through the miracle of synthetic derivatives, is buying a $1 billion insurance policy on a $10 million asset.

It isn’t investing, isn’t even trading, it’s just betting.

Nobody started it. Or at least it is impossible to figure out who started it. No one trader could have saved the issue by staying out of the fray (doing so would only have cost easy profit). There was no meeting at Starbucks. Yet the final result was just as certain.

The problem with this scenario is that conditions – primarily technology – have changed enough to allow what were always parasites to become true predators. Parasites need a healthy host to maintain their lifestyle. If they eat too much the host dies and the parasites die with it. But predators just find something else to kill and eat when all of one prey is gone.

In this case that prey is the American mortgage market, which is a fair proxy for the American economy.
