Daily Market Update 9/24/13

Rates inched lower Tuesday, largely reflecting yesterday's late rally in mortgage-backed securities.  In economic news, the July S&P/Case-Shiller 20-city home price index rose 0.6%, a bit less than forecast, and was 12.4% higher than one year ago.  Consumer Confidence fell to 79.7, close to expectations.  Results from today's 2-year Treasury auction will be released at 1:00 PM.
