Prices on U.S. bonds crept up a little higher on Tuesday, motivated by weaker-than-expected housing data. As prices rose, yields on the 10-year Treasury bonds fell to 2.71 percent from yesterday???s 2.74 percent. Additional yield may continue today, but isn???t likely as analysts expected reduced trading volume beginning today, in front of Thanksgiving. However, the National Association of Realtors presents its housing data on Monday, which may cause a whole new round of higher prices and lower yields.
