The Stratified LargeCap Index ETF (SSPY) seeks to track a stratified large-cap index that measures the performance of large-capitalization U.S. stocks using a stratified sampling methodology. This equity ETF provides exposure to major American companies while employing a systematic approach to portfolio construction that aims to reduce tracking error through statistical sampling techniques.
How It Works
SSPY uses a stratified sampling approach that divides the large-cap universe into distinct strata based on characteristics like sector, market capitalization, and style factors, then selects representative stocks from each stratum. This passive methodology aims to replicate index performance with fewer holdings than full replication while maintaining similar risk-return characteristics. The fund rebalances periodically to maintain alignment with its stratified index methodology and ensure proper representation across all defined strata.

Risks
