FNCL is one of ten Fidelity ETFs that track MSCI sector indexes. The fund competes in a crowded financial space with three popular and well-seasoned cap-weighted funds: XLF, VFH and IYF. FNCL tracks an investable market index from MSCI, which aims to capture 99% of the market cap of US financial firms, meaning it also covers the smaller financial firms in market-like weights. To meet diversification requirements,, the index employs a capping methodology, such that no group entity exceeds 25% of index weight and the aggregate weight of issuers with over 5% weight in the index are capped at 50% weight of the portfolio. In September 2016, the fund sold off all of its REITs (except for mortgage REITs) - a substantial part of the portfolio. It did so to comply with a change in GICS methodology. It increased its allocation to remaining financial industries in accord with the revamped underlying index. Prior to December 1, 2020, FNCL tracked the unconstrained MSCI USA IMI Financials Index.
