I Asked ChatGPT How the Stock Market Would Look If We Ignored the 7 Biggest Stocks

The article uses ChatGPT to illustrate how the seven largest US mega-cap tech stocks (Apple, Microsoft, Nvidia, Alphabet, Amazon, Meta and Tesla) have disproportionately driven S&P 500 returns. Removing the “Magnificent 7” would make the S&P 500 much flatter, reduce tech concentration in typical 401(k) and target-date funds, likely lower recent retirement account balances, and change the market’s risk profile—potentially lowering volatility and making US returns resemble international markets more closely. The piece concludes that investors may be more concentrated in tech than they realize and reiterates the importance of diversification and long-term discipline.
