The fund offers efficient exposure to the heavyweights in the US financials sector. It tracks an index comprising of a broad range of diversified financial service firms, insurance, banks, capital markets, consumer finance and thrift companies. Its S&P 500-only portfolio means that it's concentrated in the largest firms and avoids small-caps. To achieve its investment objective, the fund may invest directly in the index constituents securities or hold other securities with similar investment profiles through a sampling strategy. It may also use derivatives, enter securities lending and repurchase agreements, and engage in short selling to maximize its returns. The constituents are market cap-weighted with quarterly index rebalancing.
