Apple's stock price grew by double digits in 2016 despite reporting in October the company's first year-over-year annual sales decline since 2001 and a drop in the giant company's profits.

In fall 2016 Apple refreshed key items in its product portfolio, introducing a new line of MacBook Pro laptops and the iPhone 7 and 7 Plus. Those products boosted the vendor's holiday sales and that momentum carried into the new year. (In late March the company unveiled a 9.7-inch iPad tablet.)

For the company's fiscal 2017 first quarter (ended Dec. 31), Apple reported revenue of $78.35 billion, up more than 3 percent from $75.87 billion in the same quarter one year earlier. Net income for the quarter, however, was $17.89 billion, down 2.5 percent from $18.36 billion one year earlier.
