The S&P 500 has reached a historic level of earnings concentration, with just seven companies, Apple, Microsoft, Alphabet, Amazon, Nvidia, Meta, and Tesla, now producing 26% of the index’s total net income.

This group, known as the “Magnificent Seven,” dominates profitability across multiple sectors. In Information Technology, where roughly 70 firms are listed, these companies drive 67% of the sector’s earnings.

In Communication Services, they contribute 65% of the earnings despite the sector housing around 25 stocks. Even in Consumer Discretionary, they account for 35% of total profits.
