Tech investor Gene Munster criticized Wall Street's reaction to Apple's Q4 results, calling it an overreaction. He pointed out that Apple's business would have seen a 7% growth if the quarter had 14 weeks, an improvement from the 1% decline in the previous quarter. Despite surpassing predictions with its Q4 results, Apple's stock was down 0.91% in after-hours trading due to iPhone revenue falling slightly below estimates.
