JPMorgan's most recent forward-looking analysis of Apple's earnings suggests that the issue of supply-demand imbalance for iPhones has been largely resolved, paving the way for a robust quarterly performance from the tech giant. However, profit margins and cost pressures are anticipated to be pivotal factors shaping market sentiment. According to a preview report sourced from media outlets covering Apple, investors have already formed clear expectations regarding the current sales performance of iPhones, with their attention now shifting from revenue figures to profitability, especially in terms of cost structure changes. JPMorgan highlighted that while demand for the iPhone 17 series has surpassed expectations, escalating costs for components like memory could exert pressure on profit margins. Nonetheless, Apple is projected to effectively manage costs through long-term supply agreements and economies of scale. Furthermore, the steady growth and risk-mitigation capabilities of Apple's services business, acting as a stabilizing force, are also expected to positively influence its overall performance.
