A Bit of Meaningless Weakness. More Important Stuff On Deck Bonds lost ground to start the new week, but not for any compelling reasons.  If we could even make a case for the weakness being caused by something, we'd be forced to rely on unsatisfying explanations like technical corrections or a leveling off of the prevailing trend ahead of bigger-ticket data.  All that having been said, today was unequivocally a leveling-off of the prevailing trend ahead of bigger ticket data.  The focus is not so much on the 7-8bps of 10yr yield weakness on this data-free day, but rather on the 20-40bps of movement that could be seen in response to economic data and the Fed over the next 7 business days.
