Sigma Signals

Week of June 8, 2026

S&P Global confirmed that they are not waiving their GAAP profitability and “seasoning” requirements for inclusion into the widely followed S&P 500 index. This decision comes in the days leading up to what is slated to be the largest IPO in history, SpaceX. The inclusion requirements ensure that passive index funds aren’t forced to purchase shares of a company during a volatile trading period. Investments, even by passive index funds, should be made on merit rather than relying on unproven growth potential. Our Signals remain unchanged.
