DIVB selects its holdings from a diversified universe that represents 97% of US free-float market capitalization. Companies with the largest dividend and buyback programs, measured by dollar value, are chosen for the index. Constituents are selected in decreasing order of shareholder payout until 90% coverage of the aggregate shareholder payout of the selection universe is achieved. The index is weighted using an adjusted market-cap weighting scheme, where market-cap is adjusted by a total shareholder yield multiplier. At each quarterly rebalance, constituent weights are further constrained such that no individual security exceeds 4.9% weight of the portfolio. While dividend-focused funds abound in the US equity space, DIVB is one of only a few to emphasize shareholder yield. Prior to October 25, 2022, the fund traded under the name iShares US Dividend and Buyback ETF.
