Are most leaders of publicly traded companies immune from wall st analyst quarterly estimates and projections? Do they not greatly affect the company's share price?
The leaders of most public companies are indeed influenced by analysts and investors. The reason is because the leaders of most publicly traded companies can be fired by the board, and the board's perception of leader performance is influenced by analyst opinions and the opinions of large and/or influential shareholders. In Google's case, Larry and Sergey hire and fire the board, not the other way around. There is a meaningful difference between the corporate governance dynamics at Google and most other public companies.
