It typically allocates a minimum of 80% of its net assets—including any funds acquired through borrowing for investment purposes—to stocks of large-capitalization companies. The fund predominantly focuses its investments on a collection of equity instruments, encompassing common shares and other forms of equity (like securities convertible into common stock), issued by large-cap, domestically-based growth enterprises that are anticipated to demonstrate high-quality growth attributes. It's important to note that this fund operates on a non-diversified basis.
