(Updates yields, adds auction results and analyst comments) By Karen Pierog CHICAGO, Nov 24 (Reuters) - U.S. Treasury yields on the longer end of the curve rose on Tuesday as investors rushed to riskier investments, including soaring stocks. The benchmark 10-year yield, which hit a session high of 0.888%, was last up 2.7 basis points at 0.8865% and the yield curve steepened. The yield on 30-year bonds was last up 4.6 basis points at 1.6092%. Stan Shipley, fixed-income strategist at Evercore ISI in New York, said investors, driven by hopes of a closer economic recovery, were ditching the safe haven of Treasuries for riskier commodities and stocks. "With yields of 85 or 88 basis points, that's not very attractive on the 10-year (note), and (people are) going to look for returns elsewhere," he said. Economic rebound hopes spurred by progress on coronavirus vaccines, along with the commencement of President-elect Joe Biden's transition process three weeks after the election, pushed stocks higher and lifted the Dow Jones Industrial Average over the 30,000 mark for the first time. Market positioning ahead of Thursday's Thanksgiving holiday was also a factor, according to Tom Simons, money market economist at Jefferies in New York. "Nobody wants to be still holding onto big short positions," he said. On the auction front, the U.S. Treasury sold $56 billion of seven-year notes at a high yield of 0.653% and with a bid-to-cover ratio of 2.37. The offering followed auctions of two- and five-year notes on Monday. Simons said the seven-year note auction went "pretty well." "This one was slightly better than average and yesterday's (five-year note auction) was slightly worse than average," he said. The two-year U.S. Treasury yield, which typically moves in step with interest rate expectations, was last down less than a basis point at 0.1641%. A closely watched part of the U.S. Treasury yield curve measuring the gap between yields on two- and 10-year Treasury notes, seen as an indicator of economic expectations, was last at 71.90 basis points, 2.8 basis points higher than Monday's close.
