GSY: Low Duration Doesn't Protect Against Credit Widening
The Invesco Ultra Short Duration ETF offers a 4.27% SEC yield with a low 0.77-year duration, targeting above-cash returns via incremental investment-grade credit risk. GSY's incremental yield over Treasuries is primarily from credit exposure, but current credit premiums are compressed and not particularly attractive. The 0.22% expense ratio further erodes net returns, especially given the fund's reliance on low credit spreads for excess yield.
