My core position with fidelity is spaxx for which 7 days yield is 4.22 right now with er at 0.42% Also the 2 equivalent fidelity funds have higher expense ratios, hence will generally have lower yields compared to vanguard equivalent. I found this fund vusxx with 0.09% er with 7 days yield as 4.61 right now

Also the vusxx has 71% treasury bill which saves on state tax See fzfxx for a comparable fund like vusxx So overall is it better to hold cash in vusxx in a fidelity account

What am i missing here?

They’re highly liquid, earn better returns than savings accounts and are often used in. Last time i looked vusxx was my best choice in term of yield and tax advantage for holding cash equivalents, spaxx had lower yields for example Am i missing some other mmf at fidelity that it closer to vusxx? With interest rates falling, investors need to be more diligent in comparing money market funds to ensure they're getting the highest possible yield.

I have my savings in a combination of spaxx and vusxx (slightly higher rate) While there is technically more risk in treasuries vs cash, that risk is so minuscule that it is not worth worrying about. Safe enough, but more comparable to vmfxx (not vusxx)
