Shares of Apple (NASDAQ:AAPL) fell by 6% today, and as one of the most closely watched stocks on the market, any move by Apple shares is going to have a lot of analysts immediately pretending to know what caused it. In this video, Motley Fool tech and telecom bureau chief Eric Bleeker addresses one Norwegian analyst's perspective that Apple's "cycle of vogue is ending." Eric explains how Apple's superior pricing power and supply chain, its low cost percentage for research and development, and its large percentage of users who intend to upgrade to the next iPhone all suggest that there isn't a shred of evidence for this viewpoint. Ignoring Apple's rock-solid fundamentals and attributing its success to a fad that is on its way out is exactly the kind of wrong-headed thinking that costs investors money.
