Consumer Confidence: The Bloomberg Consumer Comfort Index continues to rebound from the trauma caused by the government shutdown, climbing a big 4 points to -33.9 last week. The results can range from 100, indicating every participant in the survey had a positive response to all three components, to minus 100, signaling all views were negative. The index has gained at least 4 points just 78 times out of more than 1,400 weeks since 1985, the year the index was created, and the advance is in part due to better-than-expected jobs and GDP reports last week.

Home builders were the subject of much of the rally as investors bet that continued bond buying will keep a lid on mortgage rates.
