Quarterly iPad Revenue Has a 68% Correlation With Apple's Stock Price

Bloomberg Businessweek has posted a report noting that quarterly iPad revenue has a 68% correlation with Apple's stock price. The iPad accounted for $31 billion of Apple's revenue last year which is about 20% of total sales.


Quarterly iPad revenue has a 68 percent correlation with Apple’s share price. That’s higher than the stock’s correlations to iPhone revenue (62 percent) or Mac revenue (40 percent). If we consider unit sales rather than revenue, the iPhone becomes a better predictor of Apple’s share price than the iPad, but the difference is not enormous: Unit sales of the iPhone are 77 percent correlated with the stock; iPad unit sales are 68 percent correlated.
