About this ETF
The investment seeks to track the investment results of the Russell US Mid Cap Factors Blend Style Index. The fund generally will invest at least 90% of its assets in the component securities of the underlying index and may invest up to 10% of its assets in certain futures, options and swap contracts, cash and cash equivalents. The underlying index is designed to select equity securities from the Russell Midcap Index, with exposure to five equity style factors (momentum, quality, value, size and low volatility) while maintaining a level of risk similar to that of the parent index. It is non-diversified.

Guided help: AUM is fund size. The expense ratio is the yearly cost baked into returns. NAV is the value of what the fund owns per share; the market price can sit slightly above (premium) or below (discount) it. Total return assumes distributions were reinvested. Every dataset shows its own as-of date because holdings, assets and quotes update on different schedules.
