Apple is getting ready for its most massive product launch yet with the iPhone 6, with Business Insider pointing to a new RBC note to investors that says the upcoming smartphone will be a smash hit for the iPhone maker. “Most supply chain data is pointing towards Apple gearing up to ramp 70-80 million iPhone 6 units across the two form factors (4.7”/5.5”),” RBC analyst Amit Daryanani said. “This is a notable uptick from last year when the supply chain ramped 50-60 million units.”

Apple’s iPhone 6 could be a serious blockbuster, says RBC analyst Amit Daryanani in a new note Monday. “Most supply chain data is pointing towards Apple gearing up to ramp 70-80 million iPhone 6 units across the two form factors (4.7”/5.5”),” Daryanani says. “This is a notable uptick from last year when the supply chain ramped 50-60 million units.” In English, that means Apple is telling suppliers to make ~75 million iPhone 6 phones for the second half of the year, which is ~36% more than it requested last year. This would make the iPhone 6 a giant hit for Apple. This would blow away Daryanani’s own estimates that Apple will ship 65 million units in the second half of the year. If iPhone sales hit that number, then EPS could be 10% better than Daryanani expects. Daryanani’s note helped drive Apple’s stock higher today. It closed at $99.16, up 1.2%, which puts it within striking distance of its 52-week high of $99.44. Apple’s split-adjusted all-time high is just north of $100 per share.
