If the dollar drops this usually goes up---shouldnt it be the other way around? If investors want to get out of dollar denominated debt the dollar drops which to me suggest this should follow but it acts inverse. When rates go up, value of bonds decline and this falls--this makes sense BUT rising rates suggest inflation fears so I dont really think this should fall in price. When the Fed implements QE2 and is buying the crap out of Treasuries (just started) you would think that would make this go up (kind of similar to stock buy back announcements) but----not--- this has fallen. This should be more predictable-- as the FED crushes the dollar, based on previous action, VIPSX will go up but I can hardly believe that relationship will continue to run true. I got out at 13.55 and want to put some money back into this but cant justify it as the price swings dont make sense---What am I missing? My dimmer switch is on--please enlighten me.
