U.S. stocks extended their rally on Monday, with the S&P 500 finishing at 6,305.60, its first close above the 6,300 mark and a 0.14% gain on the day. The Nasdaq Composite advanced 0.38% to its own all-time high, while the Dow Jones Industrial Average slipped, highlighting investors’ concentration in technology shares. Gains were led by megacap companies such as Alphabet, Amazon and Apple as traders positioned for a heavy slate of second-quarter earnings. Tesla and Alphabet are scheduled to report on Wednesday, and other members of the so-called Magnificent Seven will follow later in the week. Solid corporate results and resilient consumer-spending data continued to bolster sentiment, countering worries about trade policy. Market participants are monitoring an Aug. 1 deadline, when higher U.S. tariff rates on key trading partners are set to take effect, as well as a speech by Federal Reserve Chair Jerome Powell on Tuesday that could provide clues on the interest-rate outlook. Monday’s advance marks the S&P 500’s 10th record close of the year, underscoring investors’ confidence that the artificial-intelligence boom and steady economic growth can carry equities higher despite policy and geopolitical risks.
