Treasuries fell Monday, with 10-year yields rising the most in two weeks, as stocks extended their longest rally of 2015 amid expectations that the Federal Reserve will take its time raising interest rates. Debt maturing in 10 and 30 years underperformed shorter-term securities, as the benchmark 10-year note erased gains seen after an Oct. 2 report showed the U.S. added fewer jobs than forecast in September.
