Cook v. Icahn

Philip Elmer-DeWitt for Fortune:

He (Tim Cook) was surprised, he told the Journal, that Apple’s share price fell 8% after the company turned in its Q1 2014 earnings and Q2 guidance.

But while the Street was shorting the stock, Cook was in there snapping up shares – 26.7 million of them, by my calculation.

It puts in perspective the roughly 1 million shares Carl Icahn says bought on Jan. 28. link

Per a comment from the above, AAPL average daily volume is 13.40M shares. 26.7M would be 1/5th of all shares traded the past two weeks.
