KeyBanc analyst John Vinh says his November carrier survey indicates Apple Inc. iPhone 13 supply remains heavily constrained. The demand continues to outstrip availability during the Thanksgiving holiday period. While the analyst recently observed modest supply improvement, most of the stores surveyed reported not having any 13 Pro/Max availability. Carrier store DOI remains very lean at well under one day. Vinh views these results as neutral for the Apple supply chain and expects stocks to remain range-bound as constraints are likely to limit near-term upside. Companies with meaningful Apple exposure include Broadcom Inc., Cirrus Logic Inc., Qualcomm Inc., Qorvo Inc., and Skyworks Solutions Inc. By Anusuya Lahiri  © 2021 The Epoch Times.
