SSPYs index aims to provide equal exposure to companies that share related business risks, using a proprietary stratified weighting methodology. The fund manager sorts S&P 500 companies into groups based on their underlying business functions and relationships such as common suppliers, customers, competitors, and products. When two or more companies earnings are affected by these fundamental drivers, they are grouped, and their weight is redistributed across the other components. The objective is to provide a more unbiased return on the large-cap space than market-cap-weighted funds. Rebalanced quarterly, the index includes 500 components from all eight industry sectors. On September 27, 2024, the fund acquired all assets and liabilities of the Syntax Stratified ETF suite, LargeCap, MidCap, SmallCap, Total Market II, and U.S. Total Market ETF (SYUS), which had about $50.1 million combined AUM.
