Bloomberg (October 23, 2008): Roubini Says `Panic' May Force Market Shutdown. Friday Morning Update: Markets are becoming dysfunctional and S&P and DJIA futures trading already suspended today

Early Friday Morning Update: Yesterday Thursday I gave a speech in London (see video below) arguing that markets were in sheer panic and becoming literally dysfunctional and unhinged. I also made the point that policy makers may soon be forced to close financial markets as the panic selling accelerates. Indeed, we have now reached a point where fundamentals and long term valuation considerations do not matter any more for financial markets. There is a free fall as most investors are rapidly deleveraging and we are on the verge of a a capitulation collapse. What matters now is only flows - rather than stocks and fundamentals - and flows are unidirectional as everyone is selling and no one is buying as trying to buy equities is like catching a falling knife. There are no buyers in these dysfunctional markets, only sellers and panic is the ugly state of this destabilizing game.

And while panic and destabilizing market dynamics is the driver of financial markets even economic fundamentals are awful as investors are finally realizing that a severe US and Eurozone and G7 and emerging markets and global recession is coming and will be deep and protracted. As I have argued for a while equity prices may have to fall another 30% based on fundamentals alone before they bottom out. Why so? In a severe two year US and global recession S&P 500 firms earnings per share (EPS) could realistically fall to $50 or $60. If P/E ratios fall to 12 this implies the S&P 500 index falling to a 600 to 720 range. If P/E ratios fall - as likely in a recession - to 10 then the S&P 500 index could fall as low as 500 to 600. So even based on fundamental factors alone there is another 30% or more downside risk to US equities; and now, on top of such fundamentals, thee is also an ugly and nasty panic-driven market dynamics at work.
