NEW YORK (MarketWatch) -- Treasury prices turned down slightly, pushing yields up, as traders kept an eye on equities and U.S. corporate earnings. Losses may be limited as Federal Reserve Chairman Ben Bernanke's testimony to Congress, starting later in the session, is expected to be modestly supportive for bonds. "It's a sideways grind ahead of Bernanke, but one with a bullish tilt," said strategists at CRT Capital Group. Yields on 10-year notes (UST10Y 2.96, +0.00, +0.10%) , which move inversely to prices, rose 1 basis point to 2.96%, hovering near a 15-month low.
