Apple’s net income in the fiscal first quarter was US$13.1 billion, or $13.81 per share, flat with a year ago.

"Apple got driven sharply higher last year on sentiment and now the sentiment has turned. It can be quite vicious when that happens," said Norman Raschkowan, North American strategist for Mackenzie Financial Corp.
"As tech companies mature, they can still have very attractive margins but their earnings and revenue growth does slow. It doesn’t mean they aren’t great companies, but the market doesn’t value them anymore as a growth stock and that’s partly what’s happening here."

The TSX energy sector was higher amid good news from the world's second-biggest economy as China’s manufacturing sector crept higher in January to the fastest pace in two years. A preliminary version of HSBC’s monthly purchasing managers’ index rose for the fifth month in a row to 51.9 in January from 51.5 in December. Readings above 50 on the 100-point scale indicate expansion.
The report is further evidence that China’s economy is undergoing a modest recovery from a downturn sparked by the 2008 world financial crisis.
