Commentary on the economy, the markets, and business

Motion sickness quantified

You may have noticed that yesterday was a rough day for the market. And last week had gone so well, too. Shoot. This morning I was talking to some folks over at the electronic trading platform Liquidnet, and one of them pointed me to a Citigroup report that lends nice context to the recent volatility. Here's a look at some different time periods and the number of days the S&P 500 has moved up or down more than 5% during the trading day:

1950-2000: 27 days
2000-2006: 7 days
Jan. 1-Sept. 30, 2008: 20 days
Since Oct. 1, 2008: 22 days

Historically, we've seen a 5% swing less than 1% of the time. Through September, we were running at about 10%. These days, we're hitting the threshold more than half the time. Wear your seatbelts.

Barbara!

    Deck the Halls With Bailout Folly
    WilliamBanzai7

    Deck the halls with bailout folly
    Fa la la la la, la la la la.
    Tis the season for capitalist jolly,
    Fa la la la la, la la la la.

    Don we now our pin striped apparel,
    Fa la la, la la la, la la la.
    Trolling Capital Hill for taxpayer marrow,
    Fa la la la la, la la la la.

    See the sinking Dow before us,
    Fa la la la la, la la la la.
    Spell A.I.G./CITI and join the chorus.
    Fa la la la la, la la la la.

    Follow all in downward spiral measure,
    Fa la la la la, la la la la.
    While you dream of sub prime bonus treasure,
    Fa la la la la, la la la la.

    Fast away Detroit's fat SUV lead passes,
    Fa la la la la, la la la la.
    Hail the new Japanese hybrid classes,
    Fa la la la la, la la la la.

    Sing we joyous, all together,
    Fa la la la la, la la la la.
    Heedless of the bleak financial wind and weather,
    Fa la la la la, la la la la.

    does daily volatility correlate with daily trading volume? more frenetic trading activity --> more price volatility?
