With the latest purchases, Mr. Cook said Apple had bought back more than $40 billion of its shares over the past 12 months, which Mr. Cook said was a record for any company over a similar span.

“It means that we are betting on Apple. It means that we are really confident on what we are doing and what we plan to do,” said Mr. Cook, speaking in a conference room at the company’s corporate headquarters here. “We’re not just saying that. We’re showing that with our actions.”

The story also notes that Apple purchased 21 companies in the last 15 months. As usual, Apple is being very strategic with every move it makes.
