To add to this, concerns over Apple's ability to continue growth in the China, which accounted for around 27 percent of revenue in the June quarter, was also questioned amid concerns over growth in the world's second-largest economy.

"With initial pre-order sales looking particularly strong out of the linchpin China region, we believe the combination of strong first weekend sales and potential upside to iPhone numbers for the next few quarters should help remove the 'China iPhone black cloud' hovering over Apple for the last few months," Daniel Ives, analyst at FBR Capital Markets wrote in a note on Monday. He maintained his "outperform" rating on the Apple stock with a price target of $175.
