It singles out big-tech leaders — Alphabet (GOOG/GOOGL), Apple (AAPL) and Microsoft (MSFT) — as among the priciest stocks, highlighting valuation concentration in large caps. Market impact: elevated valuations among a handful of large-cap tech stocks can influence S&P 500 multiples and investor risk perception, potentially raising sensitivity of the index to tech re-rating or disappointing earnings.
