This holiday-shortened week brings us the release of an abundance of economic reports for the markets to digest. There are seven reports on the calendar with several being considered to be of high importance to the bond market and mortgage rates. With multiple moderately or highly important reports due out more than one day this week, we will likely see a fair amount of movement in mortgage rates day to day.

October's Existing Home Sales data will be posted late this morning. This report, along with Wednesday's New Home Sales data are the least important reports of the week. They give us a measurement of housing sector strength and mortgage credit demand, but the bond market generally does not rely heavily on their results.

The first important data comes early tomorrow morning brings us the first revision to the 3rd Quarter Gross Domestic Product (GDP) reading. The GDP revision is expected to show a downward revision from last month's preliminary r eading of -0.3%. Current forecasts call for a reading of approximately -0.6%, meaning that there was less economic growth during the third quarter than previously thought. This would be good news for the bond market and mortgage rates.

Late tomorrow morning, November's Consumer Confidence Index (CCI) will be posted. The Conference Board will release the CCI for the month of November at 10:00 AM ET, giving us a measurement of consumer willingness to spend. If consumer confidence is rising, analysts believe that consumers are more apt to make larger purchases, essentially fueling economic growth. This raises inflation concerns and usually pushes mortgage rates higher. Analysts are expecting a small increase from last month's 38.0 reading to somewhere around 39.5. A weaker than expected reading should be good news for mortgage rates, but a stronger than expected reading could push mortgage rates higher Tuesday.
