Big Tech earnings delivered mixed results this week as Alphabet (GOOGL) and Tesla (TSLA) weighed on the sector despite Alphabet's revenue and earnings beat, with investors focusing instead on rising capital expenditure plans. Intel (INTC) stood out with stronger than expected earnings driven by growth in its data center and AI client computing businesses. Defense stocks rallied after strong quarterly results from Lockheed Martin (LMT) and RTX Corp. (RTX), sending both shares sharply higher.
