This fund's primary strategy involves allocating a significant portion of its total assets—specifically, at least 80% and typically a greater share—to the securities that comprise its target index. Furthermore, it retains the flexibility to hold equity investments not included in that index, alongside liquid assets such as cash, cash equivalents, or various money market instruments. These money market holdings may include repurchase agreements and money market funds, potentially even those managed by the fund's own Adviser.
