Do public stock indexes represent most of the US economy?
Core argument: S&P 500 companies employ 29 million people globally against 158 million employed in the US economy, meaning more than 80% of US employment sits outside S&P 500 firms.
Most of the time in financial markets goes with talking about the S&P 500. But public markets and public companies are only a small part of the economy. Total global employment in the S&P 500 companies is 29 million, and total employment in the US economy is 158 million. Put differently, more than 80% of total employment in the US economy is outside the S&P 500 companies. This is consistent with our recent note in which we showed that 87% of firms in the US with revenue greater than $100 million are private. The bottom line is that the vast majority of the US economy is in private markets.
