I recently ran across zero duration bond funds and thought they would be a good substitution for the majority of my increasing cash holdings. I previously mentioned HYZD ( YIELD 4.87 % ) ALSO: HYGH ( YIELD 5.21% ) HYHG ( YIELD 5.86% ) HYIH ( YIELD 7.1% ) Any downside risk that I am missing in these and especially HYIH ? Are they too good to be true? TOOFUZZY
