Soluções para a tarefa
Rory Riggs is the CEO and Founder of Syntax Indices. Rory’s idea for Syntax Stratified Indices came from his career in healthcare and the industry’s statistical use of population sampling and stratification across sub-populations to control for inadvertent biases in clinical trial results. To address the potential of similar biases in index results, he and his team identified a new risk category called related business risks; developed a new classification system with which to identify and group related business risk; and implemented a stratified weighting methodology to control for the inadvertent over-weighting of related business risks that regularly occur capitalization-weight and equal-weight methodologies. Using this stratified-weight methodology, Syntax operates a family of Syntax Stratified Indices that includes a Stratified Syntax LargeCap and MidCap Index that provide stratified-weight versions of the widely-followed S&P 500 and the S&P 400.
