Vanguard Financials ETF(AMEX:VFH)

The fund is passively managed to hold US financials stocks across all market caps. The fund uses a market-cap selection and weighting scheme with a portfolio that captures the broader financials market. In September 2016, the fund sold off all its REITs (except for mortgage REITs), a substantial part of the portfolio. It did so to comply with a change in GICS methodology, the sector framework supporting its underlying index. It increased its allocation to remaining financial industries in accordance with the revamped underlying index. To ensure diversification, the index applies investment limits on regulated investment companies of no more than 25% of value to a single issuer, and the sum of the weights of all issuers with more than 5% not exceeding 50% of total assets. The index is rebalanced on a quarterly basis.
