wed is the 10 year auction, whilst thurs is the 30yr auction. if I were a conspiracy theorist, or mutual fund long bond portfolio mgr. I would think that the way the auctions go could be key to some quick gains for the fleet footed. my thinking goes as follows, 10 year auction wed. afternoon (1pm est) is mid-land to poor results, setting up for a quick move to higher yields for longer term bonds at wed close. that would set up a further quick flurry of activity early morning Thurs.  just in time for a 'well' received 30 yr auction Thursday, and sharp long term yield decline into Thursday close and further running on Friday.  just speculation on my part, but TMF (the ETF) might be an interesting play come Wednesday afternoon and/or Thursday  morning. time will tell, good trading. I'll post if I take it.
