The Dow Jones Industrial Average fell almost 1000 points in ten minutes today, wiping out $1 trillion in equity values as algorithmic trading by high-speed computers spun out of control.
What passes for sanity on Wall Street was eventually restored, and after falling 998.5 points or 9.2% in only a few minutes, stocks ended the day with a relatively benign loss of 3.2%, 347 points off the Dow, in what was still its biggest one-day tumble since February, 2009. Luckily, investors didn’t see that much of an impact during this loss. Stock markets do tend to fluctuate from time to time, so investors should expect this. Hopefully, the stock market will increase again after this, encouraging more people to try and invest their money. For those who do want to do this, it might be worth reading about welche Aktien kaufen (what stocks to buy) online to make sure the investment will be a good one. No one can predict the stock market, but choosing a safe option is always a good idea.
The more or less rational fraction of this mini-panic was apparently fear that the Spanish economy would collapse along with Greece, and then…
Robot-traders ran wild!
The 1987 crash, when the Dow lost 20% in a matter of hours, was blamed squarely on program trading, in which computers are set to sell (or buy) when stocks hit a certain threshold.
But at the end of the day, nobody knows exactly what happened, or why, and our economy continues to be ruled by a tunnel-vision coalition of half-bright wonks and predatory hustlers.

The Wall Street Journal also mentioned a few especially crazy micro-crashes:
Boston Beer Company, which produces the line-up of Sam Adams beers, went from $59.44 to… Zero!
Exelon, one of the largest utilities in the world, with a market cap of about $30 billion, declined to… Zero!
Both those stocks eventually recovered, and meanwhile the giant auction-house Sotheby’s was riding the whilwind in the opposite direction, and exploded to the absolutely senseless stock-price of $100,000 per share, before eventually returning to its typical value of $33.

Does anybody understand this shit?
Is the apparently unregulated multi-trillion-dollar hocus-pocus of algorithmic trading transparent to anybody?

Although it’s now (and probably forever) impossible for any human being to comprehend exactly how the avalanche of high-speed computer-trading began to roll down the Dow, last year Seeking Alpha ran an unusually transparent description of how so-called High-Frequency Trading can be manipulated, and even though it doesn’t specifically apply to today’s ten-minute panic, it still supplies some relevant context IMHO…
In a nutshell, Speedy Traders INC “probes” your computer algorithm with tiny offers, and in a time-frame of 3 milliseconds they uncover your high bid, like a kid luring ET out of his hiding-place with a trail of M&M’s.
Oh yeah we are such masters of our own universe here.
How do you regulate, legislate against a species in perpetual error.
Be calm. Everything is under control. Please continue to send your 401k money to Wall Street so the bankers can continue to steal it.
Fat finger my ass.
