Mortgage rates were little changed Monday following the release of weaker than expected economic data. This morning, the Chicago Purchasing Managers Index fell sharply to 48.7, far short of the consensus forecast of 54.0. Readings below 50.0 indicate contraction in manufacturing in the Midwest region. Separately, the Pending Home Sales index increased by 0.2% in October, below expectations. No other key data will be released today.
