Broadcom has initiated a $10 billion share buyback program, effective through December 31, following a 34% decline in its stock this year amid tech sector volatility. The move, which resulted in a 3% rise in shares during late trading, reflects CEO Hock Tan's confidence in the company's chip and infrastructure software business.This buyback comes at a time of significant concerns over semiconductor tariffs, with the PHLX Semiconductor Index recently dropping 7%. Broadcom's strategy balances shareholder returns with investments in artificial intelligence, reporting a 77% year-over-year increase in AI revenue to $4.1 billion. Major tech firms are increasingly turning to Broadcom for custom AI chips, positioning the company as a competitor to Nvidia in the evolving AI chip market.
