Strategy: Cash equivalent
Funds holding short-dated US government paper, where the objective is that the principal is there when you need it. Yield follows short-term interest rates with a short lag rather than being locked in, so income falls when the central bank cuts and rises when it hikes. Because the underlying holdings are nearly identical across providers, the expense ratio comes almost directly out of what you receive.
There is no growth here by design, and purchasing power erodes whenever the after-tax yield sits below inflation.
