FZDXX - Fidelity Money Market Fund

[aetherie]

I just figured there was negative interest rate for FZDXX (0.36% Expense ratio and 0.1% 7 day yield)... I was blindly transferring my uninvested cash in FZDXX without thinking of current interest rate environment. I want something equally liquid, but at least provide some interest without much principal erosion... Can you experts please help me? Thank you.

The 7 day yield, which is net of expenses, is 0.01% so the rate is not negative. Over the last 10 years the 3-month treasury bill has slightly outperformed the fund. If the cash isn't necessarily required immediately you might want to consider longer term CDs or even Tbills.
