The range of the expense ratio for the ETFs in Daffy's portfolios is impressively low, ranging between 0.13% to 0.16%. This is a testament to Daffy's commitment to providing low-cost, globally diversified funds that are selected for high environmental, social, and governance (ESG) standards. Daffy has carefully selected funds from iShares by BlackRock, a company known for its low-cost and superb reputation. Each portfolio is comprised of a balanced mix of equities and bonds, with separate funds for US and International exposure. This allows for a wide range of options for donors, from conservative to moderate and aggressive options. In addition to the ESG portfolios, Daffy also offers a cash portfolio for those who prefer not to take any market risk with their charitable dollars. This portfolio has no expense ratio (0.00%) and pays a small amount of interest (0.01%). For those willing to take a small amount of market risk, Daffy offers a low-cost portfolio of short-term inflation-protected securities from Vanguard with an expense ratio of only 0.04%. Daffy's investment philosophy is centered around the belief that every penny contributed to your fund counts. They offer a total of 9 portfolios, each designed to suit different charitable objectives. This flexibility, combined with their commitment to low-cost, high-quality funds, makes Daffy a great option for a Donor-Advised Fund (DAF).
