There's not much to say about Monday other than "we'll take it!" Despite an absence of new motivations (today's data wasn't in the "market mover" category), bonds added to last week's already brisk rally. Longer-term yields outperformed as the yield curve continued a correction from the longer-term highs/wides hit last Tue/Wed. In other words, some of the motivation could be coming from curve traders who are more concerned with how bonds perform against one another than with simple gains/losses.
