Quote from trade-ya1:
I'll make a controversial statement here. While it is highly likely that we will see an orderly decline, we will not see a crash anymore due to the proliferation of hedge funds. Reason being is that the market has much more 2-way action due to hedge funds (longs and shorts) which will buffer the market on the way down with shorts looking to cover positions. Back in '87 there was relatively no significant short position (or 2-way action) in the marketplace and hence things fed on themselves. This is why i really can't understand why some countries frown upon short-selling in their markets. It creates a dampening of volatility by creating natural buyers on selloffs. Just my 2c.
Quote from illiquid:
The Fed-speak as of late seems directed more at the bond market, as if they are trying to make sure a bid remains in treasuries; there are any number of players that could get hurt from quickly rising rates, FNM for one, China, Japan could also become sellers.

quote from mg financial...
"Recall that an orderly decline in the dollar turned ugly was the very backdrop in 1987. Only this time the US is the world's largest debtor nation, not a net creditor, which means the downturn could be worse as it requires $2 billion in foreign financing a day. In the near term US deficits may continue to be funded by Asian central banks, but it may eventually take a sharp rise in bond yields (wanted or not) to stop the dollar's decline."

Quote from Pabst:
While I agree that we'll never see a one day 22% break again in our lifetime (you stats guys can figure out what a tremendous statistical anomaly '87 was)I'm going to argue your statement with something even more controversial. [/i]I don't see any evidence that liquidity buffers volatility! [/i] The ratio of strong vs. weak positions, the equilibrium remains constant regardless of how many traders are positioned.
The Treasury market, far more "liquid" and volumous than equities, had a rally the week of the '87 stock crash that was as dramatic on the upside as the crash was on the downside. No one accused program traders or options expiration (Friday before crash) for the rally in bonds. Instead it was "flight to quality." 10 Bond pts overnight on Monday-Tuesday. And that's in a market that always had arbs and hedge funds providing liquidity. It doesn't matter if it's 10 guys trading or 10,000,000, all it takes is for some fraction of positions to become so dislodged that it's like a game of musical chairs at Madison Square Garden instead of someone's living room.
