US Treasuries advanced in the wake of the latest GDP numbers, which also whetted the appetite for an auction of US$35 billion of five-year bonds.
"It was a fair auction, decent demand-global fixed-income continues to trade very, very well despite the fact most market pundits were calling for higher rates this year in an improving economy," Guy Haselmann, an interest-rate strategist in New York at Bank of Nova Scotia, which as a primary dealer must bid at US debt auctions, told Bloomberg News. "Growth and inflation expectations have been overly rosy for four years in a row, and the risks are they will continue to be overly rosy."
Shares of Monsanto climbed, last up 5 per cent, after the company upgraded its full-year outlook and announced a US$10 billion share buyback.

"That performance in a more challenging agricultural environment speaks to the breadth and customer value of our product portfolio."
Shares and Barnes & Noble rose, last up 4.9 per cent, after the book retailer said it would spin off its Nook business. It also posted a quarterly loss that shrank from the previous year.

"We have determined that these businesses will have the best chance of optimising shareholder value if they are capitalised and operated separately," Huseby said. "We fully expect that our Retail and NOOK Media businesses will continue to have long-term, successful business relationships with each other after separation."
