The 10 biggest stocks are faltering, and it's dragging the S&P 500 down

Apple (AAPL) and Nvidia (NVDA) may be renewing their battle for the world's most valuable company, but a challenging few months for the S&P 500's (^GSPC) 10 largest companies are holding back the broader index. The 10 biggest stocks in the S&P 500 have started to falter again relative to the rest of the market, RBC strategist Lori Calvasina rightly pointed out in a new note. These 10 stocks include Apple, Nvidia, Amazon (AMZN), Broadcom (AVGO), the two classes of Alphabet (GOOGL) (GOOG) stock, Micron (MU), Meta (META), Microsoft (MSFT), and Tesla (TSLA). Their stutter step weighs on the overall stock market given their weight in the benchmark index.
