Apple Inc. shares extended their rebound on 1 July, rising about 1.9% in midday New York trading and touching their highest level in roughly six weeks. The move adds to an advance of around $8 recorded in the previous session and confirms the stock’s break above its 50-day moving average, a technical threshold it had spent most of the past month below. The two-day rally follows a period of listless trading and underscores renewed momentum in the world’s most valuable technology company.
