The S&P/TSX Composite High Beta Index is designed to measure the performance of the 50 constituents in the S&P/TSX Composite that are most sensitive to changes in market returns. For this index, the market is represented by the performance of the S&P/TSX Composite. Sensitivity is measured by the beta of an individual stock. Beta is the slope of the regression line of a security's trailing 12-months' daily price changes versus the daily changes of the S&P/TSX Composite over the same period. Constituents are weighted relative to their level of market sensitivity, with each stock assigned a weight proportional to its beta. The index is designed to serve as a benchmark for high beta strategies in the Canadian equities market.
