What’s the downside/risk to investing some idle money in bond fund like PRFHX? Assuming this is clearly idle money not part of taxable or non-taxable equity investments. I feel like it’d be a good diversification from my equity and real estate investments.
Language/definitions are important here. IMO, "investing idle money" is not the same as "parking cash".
First order of business is deciding when the money will be needed, and if a decrease in value is acceptable between now and then.
