For Apple (NASDAQ:AAPL), there was a time when everyone was talking about the iPhone X “super cycle.” Analysts were saying that the new-and-improved iPhone X would have enough bells and whistles to spark unprecedented upgrade demand, and that such demand would push AAPL stock way higher. Instead, the iPhone X was pretty much a flop from a demand standpoint. AAPL stock dropped after prelim iPhone X numbers were released.
