In 1927 Werner Heisenberg introduced the Heisenberg Uncertainty Principle in one of the foundation papers of quantum mechanics. He was awarded the Nobel Prize in physics primarily because of it. The HUP might appear to have nothing to do with investing. But I believe the HUP is as critical to the strong disagreements about indexation as it was to quantum mechanics.

Simply put, the "uncertainty principle'' states that any and every measurement process affects and alters the state of any entity being measured. One cannot, therefore, ever know at ...
