Straightforward Session as Traders Wait For More Monday ended up being rather uneventful for the bond despite its role as the lead-off hitter for an all-star line-up.  There were no significant economic reports on tap, but the 3yr Treasury auction managed to come in weak enough to prompt a bit of additional selling.  Losses were short-lived and trading levels returned to pre-auction levels about 90 minutes later.  That left a sideways-to-modestly-weaker tone intact for the day as traders wait for ultra-high consequence data and events on Wednesday.
