Analysts everywhere for all companies behave the same way. Those for Apple, because they keep tight control over information about forthcoming products, must continue to report something. Analysts are in the business of making money buying and selling stock; no transaction, no money.
Transactions are executed among brokers and brokers and the public who hold Apple stock. Each broker manages transactions between their clients making fees coming and going. Clients are all different, each are biased, and each will buy or sell based on the same information, interpreting that information according to their biases. It's that differential between biases that accounts for transactions. Those who buy and hold don't listen.
But all these rumors are ultimately good for Apple. Continuous advertising without Apple having to spend a dime.
I wonder how these rumors effect apple competitors? They must monitor each other and must be prepared to react to each other, while continuing to execute their own plan and do R&D.
Apple under Jobs publically had said they only focus on executing their plan and are not driven by what the others are doing. Apples theme of only wanting to make great products, seems to me, reflects this approach and why Apple seems late to the game when competitors market a feature and Apple doesn't seem to play oneupmanship games -- it's not in there plans.
For brokers covering other companies, and sectors, there are differentials that cause transactions which make them money. It recently was suggested that a relatively new company had developed a new medical test, and was going through the hoops of getting approval to market it. The experimental trials showed certain results. That is all public knowledge. Each analyst has a different opinion as how the tests compare to existing tests on the market, what the regulatory agencies will do at each step of the approval process, and how medical insurance companies will cover or not cover the procedure, and whether a doctor will order this test or a competitors. All these different perceptions affect transactions and stock price. Uncertainty generates money.
No one knows what will happen until it happens. Only then will we be able to separate the winners from the losers.
