Apple's new CEO Tim Cook faces his first earnings report test

Apple's new CEO John Ternus will host the first earnings call, facing three major challenges: holiday quarter performance, artificial intelligence, and the cost of storage chips. Analysts expect that rising storage chip costs will drag down quarterly profit growth. Apple's fourth-quarter revenue is expected to grow nearly 11% to $113.39 billion, with net profit expected to increase by about 6% to $29.04 billion.
