The fund provides full replication exposure to the Russell 1000 Index, which covers much more of the market than a typical US large-cap fund. The portfolio extends well into the mid-cap space and includes some small-caps too. Overall, the fund is broader and less concentrated than other large-cap funds. It is also slightly riskier, thanks to its collection of smaller holdings. Still, the fund provides representative coverage of the large-cap space, with exposure to both growth and value styles. The fund's plain vanilla exposure shouldn't offer many surprises for investors holding onto the fund longer-term. Like other Russell Indexes, the index is reconstituted annually.
