Defiance Robotics Actuators ETF (AT) 주가, 시세, 뉴스 및 이력 | Benzinga

To achieve its investment objective, the Fund invests at least 80 percent of its net assets (plus borrowings for investment purposes) in Robotics Actuator Companies (as defined above). The Fund will generally use a replication strategy to achieve its investment objective, meaning the Fund will generally invest in all of the component securities of the Index in the same approximate proportions as in the Index. However, the Fund may use a representative sampling strategy, meaning it may invest in a sample of the securities in the Index whose risk, return, and other characteristics closely resemble the risk, return, and other characteristics of the Index as a whole, when the Funds sub-adviser believes it is in the best interests of the Fund (e.g., when replicating the Index involves practical difficulties or substantial costs, an Index constituent becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Index).
