Active to Passive and Back Again

FT article saying that passive fund management is set for growth giving the disillusionment of investors with the benefits of active fund management. Interesting piece was the bit where the growth in index-based investment may ultimately introduce index-inclusion distortions in constituent pricing, so ultimately swinging round to benefit those active fund managers that are still around to see this. Makes sense as there is always some money to be made (and lost!) when everyone starts to do the same thing, or maybe I am already being taken in by the forward-looking PR departments of the active fund managers?...
