To wit, Cisco has told the Wall Street analysts (employees who work for brokerage houses to provide "expert" advice to investors) that it expects to earn 40-45 cents a share on $10.5-11 billion in revenues. One analyst publishes that they expect 43 cents on $10.652 billion; another analyst publishes that they expect 40 cents on $11.1 billion, etc. See Whisper Number ,Buy side, and Sell side for more gory details.
