Thursday’s ferocious plunge in US equities remains a mystery

invisibleSHIELD case for iPad“The day after $1,000bn was briefly wiped off the market value of US equities, traders were still trying to work out what caused share prices to plunge and then rebound so dramatically in a matter of minutes,” Michael Mackenzie and Henny Sender report for The Financial Times.

“The conventional wisdom held that an incorrectly typed sell order – one that confused ‘billions’ for ‘millions,’ for example – was the likely culprit,” Mackenzie and Sender report. “‘The trigger for the sell-off was most likely some kind of errant order, a fat-finger typo, which set off a chain reaction of selling,’ said Sang Lee, managing principal at Aite Group. ‘I would be shocked if that was not the case as the fall in stocks was so sudden and extreme.'”

MacDailyNews Take: A typo? Really? Might we be so bold as to wonder why this never happened before? Everyone’s been typing just perfectly for years? Puleeze. And, if true, any system that can fail so spectacularly due to a single typo doesn’t deserve to be called a “system.”

Mackenzie and Sender report, “However, despite the persistence of this story, officials were struggling to idenfity a specific cause. ‘We still don’t know what was the initiating signal for the trading activity we saw on Thursday,’ said Jeff Wecker, chief executive officer at Lime Brokerage. ‘The verdict is still out.'”

“What was clear was the ferocity of the fall. Just before 2.40pm on Thursday, the S&P 500 index, the US equity market’s benchmark, fell from 1,120. Inside six minutes, it bottomed at 1,065.79, a slide of nearly 5 per cent,” Mackenzie and Sender report. “By 3.00pm, the index was moving above 1,120, although still down 4 per cent on the day before, settling 3.2 per cent lower by the close.”

Mackenzie and Sender report, “One government official said the activity reinforced worries that ‘the market has outpaced the ability of the infrastructure to handle it. We have detached finance from the real economy and created a monster.'”

“The Securities and Exchange Commission and the Commodities Futures Trading Commission said they would ‘review the unusual trading,'” Mackenzie and Sender report. “Hearings have been scheduled for Tuesday before the House financial services subcommittee on capital markets.”

MacDailyNews Take: Oh, goodie. Congressional subcommittee hearings are always so productive.


  1. Someone wanted all gains this year to be erased….?

    Lets see now, politically would anyone benefit from trying to portray things as glum and disastrous? Is this a diversion? Is this a last run at everyones money? Is this the dress rehearsal?

    Apple is solid. Know your company.

  2. Not a mystery to me… Bwa ha ha ha ha!

    Perhaps the rigid automatic trading systems have had an element of chaos introduced. The market is a dynamic system if ever there was one and the “typo” from yesterday certainly qualifies as one big nasty butterfly. More like fricking mothman.

  3. If your going to give your take and speak your mind on the news tell your name half the time you make me sick with the retarted shit you say. That way if you do post who’s giveing there take I can just skip it and not wast my time…..

  4. Imagine the disasterous effect if someone ever accidentally typed “gazillion” instead of “twelve” !

    (sarcastic/sardonic comentary on the absurdity of the claim that it was a “typo”- what do they take us for, idiops?)

  5. I don’t know what disturbs me more: the probability that the trade-typo explanation is a lie or the possibility that it’s not.

    Stop loss triggers hit in retirement and investment accounts all over the world while hedge funds and investment bankers rushed in to scoop up the spoils.

    In the end does it really matter if it was an intentional theft of some large fraction of $1 trillion or an unintentional theft of the same? A huge amount of wealth changed hands that should not have. It might well have been the greatest robbery in the history of the world.

    Two predictions: the system will not be changed and this is not the last time this will happen.

  6. This is the biggest BS answer I have ever heard. One mistake sends the DOW down 1000 points. Bulls$&@. Do they want investors scared of their shadow? Because crap like this will erase all of the confidence in the market.

  7. As the manager of the Airline, I’d like to apologize to the families of the victims of that passenger jet that crashed.
    You see, the pilot typed a “C” instead of an “F” on his keyboard.

  8. @Brian, “If your going to give your take and speak your mind on the news tell your name half the time you make me sick with the retarted shit you say. That way if you do post who’s giveing there take I can just skip it and not wast my time…..”

    When you learn to spell, I will do just that. Just love those retarts!

  9. Don’t mind Ron. He’s just an astroturfer, paid by the RNC to spread slime. And this is just the beginning of a volcano of spew from his ilk.

    If not, then Ron, pray tell what motivates you?
