The investment objective of the Underlying Fund is to closely track the ChiNext Index to minimise the tracking deviation and tracking error. The Underlying Fund mainly adopts a full replication strategy and invests in the constituent securities of the Index and alternative constituents. The Underlying Fund strives to control the average daily tracking deviation within 0.2% in absolute value and the annual tracking error within 2%. If the tracking error exceeds the above range due to adjustment of the compilation rules of the Index or other factors, the Underlying Fund Manager shall take reasonable measures to avoid further expansion of the tracking error
