Common metrics include Average Dollars Traded, Share Turnover, and Bid Ask Spread.| |Market Sensitivity|Clarify the common variations in stock returns attributable to the performance of their local market indices. Leverage regressions performed between security-level and market-index returns across different return horizons and methodologies. Metrics are derived from FactSet Prices and include Beta R-Squared, Up Market Beta, and Down Market Beta.| |Momentum|Analyze the historical momentum of a security and uncover how each underlying data item, calculation, and horizon can be meaningful in different situations.
