Apple's free cash flow is "mind-blowing" and can push shares of the tech giant to $150, Barclays analyst Ben Reitzes told CNBC on Tuesday.
In the last quarter, that free cash flow per share beat the Street by about 40 percent, he said.
"Free cash flow is what, in my training, pushes stocks and really moves it. That's what you get to reinvest in the business, buy other companies and ultimately return cash to shareholders," Reitzes said in an interview with "Squawk Alley."
He anticipates the free cash flow, which he said was overlooked by many in the last earnings report, will hit people on a delay, especially into a big stock buyback program.
