Is some of this down to really agreeable shareholders? My layperson's understanding is that there's been a long term trend where more shares are through index and other passive funds, and that these rarely put any pressure on management. Is it possible to have a fund which is passive in the sense of not trying to pick and predict stuff, but is "activist" in the sense of pressuring management based on some general good governance principles?
