Mortgage rates remained virtually unchanged Friday following the release of weaker than expected economic data. The October Core PCE price index, the Fed’s preferred measure of inflation, rose 0.1%, and was a tame 1.6% higher than one year ago. Personal Income was flat. The Chicago PMI manufacturing index rose to 50.4, a bit below forecast. Readings above 50.0 indicate expansion in the manufacturing sector. Stocks moved modestly higher. The big news next week will be Friday’s release of Non-farm Payrolls and the Unemployment Rate. No other key data will be released today.
