Magnificent Seven Back, Lead Market Higher

The article argues that the Magnificent Seven mega-cap tech stocks are again driving the S&P 500 higher, restoring a positive market perception centered on renewed faith in AI. A composite of the Mag 7 fell from $65 to $55 earlier in the year and has rebounded to $66.32. Nvidia’s leadership and strong private-market AI valuations (OpenAI at $853B, Anthropic at $800B) are cited as key catalysts, supported by expected outsized earnings growth for the Mag 7 versus the rest of the S&P 500 per Morgan Stanley. The piece highlights individual moves (Nvidia up ~8% YTD, Amazon ~7.5%, Microsoft down ~14%, Tesla down ~12%) and concludes the Mag 7 could remain market drivers if earnings and AI progress continue, implying continued concentration risk for the index.
