Positioning and Data Deliver Double Whammy For Bonds

There were no whammies last week as bonds drifted sideways to slightly stronger in a narrow range.  The new week/month began with an unpleasant double whammy, unfortunately, due to positioning and economic data.  Traders began selling in waves right out of the gate.  The first two waves (8am and 8:20am) were best explained by traders closing out last week's 3.5-day weekend protections and other traders opening new positions for the month of April. Additional selling followed the stronger PMI data (both from S&P and ISM) which included higher price components.  Longer-dated Treasuries fared much worse at first, but short-term yields closed the gap a bit by the afternoon.  All told, 10yr yields jumped more than 12bps to close just over the 4.32% technical level.   MBS lost roughly half a point by 4pm.
