The S&P 500 reached a new high as the market rally broadens across software and memory stocks. Investors reacted to positive updates from companies like Workday and SanDisk, which countered softer performance in other tech hardware sectors. While individual AI stocks face resistance, the broader indexes show signs of renewed strength.

Workday shares spiked 18 percent on rumors regarding a potential buyout, driving gains across the software sector. Meanwhile, SanDisk provided a bullish long-term outlook, which pulled up peers like Micron Technology and Seagate Technology. These moves helped the Nasdaq composite advance nearly one percent during Thursday's trading session.

Applied Materials reported earnings that beat analyst estimates, yet the stock saw pressure in extended trading. The company remains a key bellwether for the chip industry, and its future guidance will likely influence market sentiment in the coming days. Investors are also watching Reddit, which is set to join the S&P 500 index next Tuesday.

Economic factors continue to provide a backdrop for these moves. Oil prices dropped over two percent, and the 10-year Treasury yield declined to 4.64 percent. These shifts in the macro environment suggest a cooling in inflation concerns, providing more room for equity growth. As the market tries to break out of its recent pause, keeping an eye on sector-specific leaders will be vital for portfolio management.
