A recent analysis using ChatGPT examined how the stock market would appear without the Magnificent 7 stocks—Apple, Microsoft, Nvidia, Alphabet, Amazon, Meta Platforms and Tesla. These seven megacap tech companies have driven a huge portion of U.S. market gains since 2023. ChatGPT noted they account for roughly 25% to 35% of the S&P 500’s total value, depending on recent price moves, and in some recent years have contributed the majority of the index’s gains. If they disappeared, the S&P 500’s recent returns would be significantly lower, and some years that looked like strong bull markets would look modest or even flat. Without those seven companies, the tech percentage of a portfolio would shrink dramatically, other sectors could have more influence, and volatility could potentially decrease, though growth would likely be slower. Regarding risk, with the Magnificent 7 there is higher concentration risk and bigger swings if tech sells off; without them, there is broader participation from smaller companies and potentially steadier but slower growth.
