Zain Asher is joining us from the New York Stock Exchange right now. Give us where the stock stands, Zain.</s>ZAIN ASHER, CNN BUSINESS CORRESPONDENT: Earlier today, the Dow was down about 200 points and now it's down about 76 points. We had a rocky week on Wall Street. And the investors are saying, if it weren't for the fact that you had long-term investors buying in, the swings this week, they would have been wilder. This is the perfect storm. We have a lot of money running for cover out of emerging markets. The idea is that, as the Fed continues to taper, you'll see the rise here and investors won't need to chase yields in developing nations. You had a slow down in China for quite sometime. Manufacturing certainly contracting over there. And the Fed this week deciding to take another $10 billion off the table as well. In terms of today, you are seeing investors begin their rebalance the portfolio at the end of the month -- Wolf?</s>BLITZER: All right, Zain, thanks very much. We will continue the breaking news coverage right after this.
