NEW YORK (MarketWatch) -- Treasurys prices held onto small gains on Thursday, nudging yields lower, after the Labor Department said initial claims for unemployment benefits were flat in the latest week at 505,000. Yields on 10-year notes (UST10Y 3.36, +0.04, +1.17%) fell 1 basis point to 3.36%. Still to come is a manufacturing report from the Philadelphia Federal Reserve, the government's leading indicators index, and the Treasury Department's announcement of how much in notes it will sell next week.
