US stocks rallied to start the holiday shortened week with the S&P 500 up 1.6% the Nasdaq jumping 2.6% and the Dow adding just over 300 points as investors grew more confident the Fed will ease policy soon. New York Fed President John Williams signalled there is room for a near term rate cut and Fed Governor Christopher Waller said recent labour market softening makes a December trim plausible.. Futures now put roughly a 79% probability on a 25bp cut at the Dec 9 and 10 meeting according to CME FedWatch. Traders also face a busy economic calendar this week that includes delayed US retail sales and PPI data which could still sway the Fed’s final call. Technology led the advance with Broadcom surging more than 10% on a revived AI infrastructure trade and Alphabet jumping over 4% after Gemini 3 related developments propelled the stock past Microsoft in market value while Tesla rose over 7% after Elon Musk flagged progress on next generation AI chips.
