The S&P 500 reached a new record high, rising 0.41% to 6,978.58, while the Nasdaq Composite gained 0.91% to 23,817.10 and the Dow Jones Industrial Average fell 0.83% to 49,003.42 due to healthcare weakness. UnitedHealth Group saw a 20% decline, impacting the Dow, while chipmaker Micron Technology and Amazon rose on tech and AI strength. Micron announced a $24 billion memory plant in Singapore, and Amazon decided to transition Fresh and Go stores into Whole Foods, boosting market sentiment.

Technology, semiconductor stocks, and AI-focused investments are driving the market, while Amazon’s strategic move to expand Whole Foods was well-received. Market watchers are eagerly awaiting results from the Magnificent Seven companies.
