HSBC upgraded Broadcom (AVGO) to a buy from a hold rating. Diane King Hall discusses the analyst call that AVGO's custom chips revenue will beat market expectations. Shares of Broadcom touched new all-time highs following the HSBC upgrade. Diane adds that Street chatter has led some to add AVGO to the "Mag 7" group, and says that hyperscaler growth would also be a catalyst for Broadcom.
