The iShares Preferred and Income Securities ETF (PFF) offers a high yield of about 5.6%, but charges a 0.45% annual fee that can significantly reduce long-term returns. The fund's value is sensitive to rising Treasury yields and is concentrated in financial sectors like banks and insurers, which carry credit risks. Monthly payouts vary and the fund's structure exposes investors to interest rate and credit risk, making the yield a compensation for these risks. Cheaper alternatives exist, and investors should weigh whether the premium yield justifies the risks and fees before investing.
