What this fund is
Objective, as filed

The investment objective of BlackRock Technology Opportunities Fund (the Fund), a series of BlackRock Funds SM (the Trust), is to provide long-term capital appreciation.

Strategy, summarised

The fund invests at least 80% of assets in equity securities of U.S. and non-U.S. technology companies across all market capitalizations, selected by BlackRock for rapid and sustainable growth potential from technology development and use. The fund may also use derivatives, including options and futures, as substitutes for direct positions or to reduce currency risk, and may invest in Rule 144A private placements and IPOs. Because the fund's selection of which companies qualify as technology companies is discretionary, its composition and returns depend on BlackRock's determinations.
