Let me add that these investment items will take a long time to fall from their peak values (at the lowest interest rates) to their lowest values (when interest rates finally peak next).
So for all the "Quick-draw McGraws" out there, don't use up your ammo too quickly. The shooting might go on for as long as a couple of years. Plan enough cash to be able to buy into at solid 30% to 40% discount and then wait and use the cash wisely. One buy a quarter should be enough at first. After that maybe one buy a month to the bottom.
