Tech Giants Apple and AMD Experience Contrasting Fortunes in Recent Week

Apple reported strong earnings, boosted its dividend, and announced a $90 billion share buyback program, leading to a rise in shares. AMD had a roller coaster week, reporting better-than-expected Q1 but issuing disappointing guidance, and then clawing back some gains after a report that Microsoft is helping finance its expansion into AI chips. Qualcomm's weak guidance led to a slide in shares, while Square reported better-than-expected Q1 results and raised its full-year adjusted EBITDA forecast. Coinbase's Q1 results were better than feared, driven by cost cuts and a jump in subscription revenue, leading to a rise in shares.
