no book- this might all be complete bs...
1. investor's goals may not be the same/aligned with the best interests of the company as a whole
2. most large investors are institutions that have many other things to do (think of some massive pension), essentially not a priority for them to effect change in a company
3. investor's time frame is shorter and can sell at any point- interests might be more ST than what is LT best for co.
4. costs vs benefits- not worth the time, effort, legal fees, etc. for a large holder to necessarily be an activist
5. who is monitoring the activist? no monitoring of the supposed monitor.
