Treasurys were marginally higher in early trading Wednesday, supported ahead of expected purchases of debt maturing between 2010 and 2011 by the Federal Reserve during the session. Bonds also benefited from weakness in equities as Alcoa's worse-than-expected loss in the first quarter sparked fears of continuing losses. Ten-year note yields , which move in the opposite direction of prices, fell 2 basis points to 2.88%. Later on, the Treasury will sell $35 billion in 3-year notes , the second of three big auctions this week. Also, Fed policy makers will release minutes of their March 18 meeting, when they decided to begin buying Treasurys.
