Not doubting that. Was just keeping an eye on if, where, and when circuit breakers would be triggered.

Speaking of that, does the NYSE have some ? How can stocks like LEH or AIG fall that low ?

Funny you should ask. They are set each quarter, so they are callibrated to current market levels.NYSE Circuit Breakers for Q3 2008The debate, as you might expect, concerns pent up demand, among other things.People are going very hard on the moral hazard in some of these forums as well. They do not protect individual stocks through the breakers.

Funny they still use points instead of percentage ... that would save some time each quarter to redefine the points.

Re: points vs. percentagePolicy makers opted for fixed vs. floating standard

Just don't believe circuit breakers are the way to go. I thought the only reason they were introduced was after 1987 and the software went wrong and started just selling before anyone could stop it. There I think perhaps they add some value, but in reality I think algo models are more sophisticated nowadays and you should allow people to trade in an open market.

Just to clarify:I'm not a naive evangelist for standing public policy solutions, but have to factor them in.Never mind vacuuming up the nickels with lots of leverage, sometimes there are Ben Franklins in the streets.And look at what's happening to the shorts now. I imagine that will have some unintended consequences.
