Treasury 10-year notes dropped for a sixth day, the longest streak in two years, as a report showing new-home sales rose more than forecast added to speculation a Federal Reserve program to boost the economy may be gradual. Thirty-year yields climbed for a second day while two-year yields were little changed amid speculation signs of growth will allow the Fed to buy fewer securities than some traders estimate in a tactic known as quantitative easing. Pacific Investment Management Co.’s Bill Gross said a renewal of asset purchases will likely signify the end of a 30-year bull market in bonds. The U.S. sold $35 billion of five-year notes today. “There’s not a lot of upside to the Treasury market,” Sean Simko, who oversees $8 billion at SEI Investments Co. in Oaks, Pennsylvania, said before the auction. “The speculation trade of getting ahead of the Fed is starting to slow down.”
