Rates inched lower Friday as key economic data came in close to forecast. Preliminary Gross Domestic Product (GDP) figures indicated that the economy grew by 2.0% in the third quarter, matching expectations. Consumer Sentiment fell to 67.7 in October, the lowest reading since last November. The Chicago Purchasing Managers Index increased to 60.6, beating the consensus forecast of 58.0. Stocks were mixed. Mortgage-backed securities markets may be highly volatile next week with mid-term elections on Tuesday, an FOMC meeting of the Fed on Wednesday, and the October Non-farm Payrolls report on Friday. No other data will be released today.
