Advanced Micro Devices (AMD) climbed roughly 13% for the week, hit an all-time high and recorded a 12‑consecutive‑day winning streak in a run that exceeded 40%. Microsoft was up more than 14% for the week, pacing for its best week since 2007 after a steep loss in the prior quarter. Tesla gained about 14% after CEO Elon Musk said the company reached a milestone on its AI5 chip. ETFs and other chipmakers also rallied: the iShares Expanded Tech-Software ETF (IGV) was up ~15% week-to-date and multiple chip firms showed strong April performance, reflecting renewed investor optimism around AI, data-center demand and semiconductor partnerships.
Large weekly gains among major cloud, chip and software companies signal renewed investor optimism in AI infrastructure and semiconductor demand, which can influence capital allocation and technology investment across the industry but does not represent a platform policy or technical release.
