Tim Cook's AAPL reminds me of a pony trying to stand for the first time after birth. As an investor I'm happy the company surprised on the upside but let's face facts -- AAPL's growth and profits are declining.
"On Monday, Apple reported a profit of $7.5 billion for the fourth fiscal quarter, on revenue of $37.5 billion, down from earnings of $8.2 billion on $36 billion in revenue during the same period last year.
This is not at all the reason for the price drop today, since this is really old news for the markets. (If you went into the 'Analyst Estimate' section of, say, publicly available data source such as Yahoo!Finance, you'd see that it was right there for months on end.)
Just because you read it for the first time somewhere yesterday doesn't make it market-moving news.
