title: 🚀 Big Tech Is Carrying the Entire Stock Market — Literally
description: "Alphabet ($GOOGL) has been the single biggest driver of the S&P 500 this year…\naccounting for 19.4% of the index’s entire YTD gain.\n\nThat’s what happens when you add $1.3 trillion in market cap in 11 months.\nRight behind it?\nNvidia ($NVDA): +16.0% contribution (+$1.05T)\nBroadcom ($AVGO): +$520B\nMicrosoft ($MSFT): +$380B\n\nTogether with the rest of the mega-cap giants, the top 10 stocks now make up 59.4% of the S&P 500’s total gain this year.\n\nWhich means the other 490 companies combined contributed just 40.6%.\n\nSource: The Kobeissi Letter, econovisuals"
